SHANNON HURRICANE IVAN IN 2004, : THE BLIZZDAR OF 1993, THE HEATWAVEF O 1988, THE FLOOD OF 1936. JUST A FEWXA EMPLES FROM HISTORY OF DAMAGING, SEVERE WEATHER IN SOUTHWESTERN PENNSYLVAA.NI MIKE WHILE AN 8-DAY FORECAST : GIVES US A GOOD IDEA WHAT’S COMI UNGP THIS WEEK, PREPARING FOR YEARS TO COME IS A LITTLE HARDER. WITH LIVES ON THE LINE, AS WLEL AS HOMES, HILLSIDES, RIVERS, TREES, BRIDGES, DAMS AND POWER LINES, TONIGHT WE LOOK FORWARD , TO THE FUTURE. THUNDERSTORMS TOP THE LIST WHEN YOU LOOK AT REPORTS OF EXTREME WEATHER FROM THE PAST TWO DECADES. LIGHTNING, WIND, RAIN CAN TOPPLE TREES, LEAVE HOMES IN RUINS, AND PUT LIVES IN DANR.GE SHANNON AND FLASH FLOODING : STANDS OUTS AA GROWING PROBLEM FOR OUR REGION. WE BEGIN WITH ASHLEY ZILKA AND THE LIFE CHANGING IMPACTS THIS WEATHER CAN BRG.IN IT HAS ALWAYS BEEN AN ISSUE. AND I KNEW SOMEBODY WOULDID E THERE SO WHEN IT HAPPENED TO HER, THAT’S JUST WHEN I WENT CRAZY. HAD LIFE FLIGHT ON STANDBY AT THEY RIVERTOWN PORT HOUSE AND THEN THEY HAD CALLED IN THE WATER SEARCH-AND-RESCUE TEAM. ASHLEY DOREEN CHATKIN DOESN’T : KNOW HOW HER DAUGHTER SU RVIVED. IN JULY OF CAITLIN WAS BEHIND 2019, THE WHEEL OF HER CAR IN MONROEVILLE WHEN SHE WAS SWEPT 165 FEET OFF OF LOGANS FERRY ROAD BY FLOOD WATERS. CAITLIN NOW SHARING THE DETAILS OF THAT DAY FOR THE FIRST TIME. >> AND BEFORE I COULD DO ANYTHING, MY CAR SPUN IN A CIRCLE, TOOK ME BACKWARDS, I CALLED MY MOM, TOLD HER I HIT A TREE, I HAD NO IDEA WHERE I WAS BECAUSE IT WAS PCHIT BLACK OUTSIDE. IN TTHA MOMENT I COULD FEEL THE , WATER RISING UP UNDERNEATH MY BUTT, SO I WAS LIKE OK I HAVE TO GET OUT OF THIS R.CA I DON’T KNOW HOW I AM GOING TO GET OUT BUT I’M GOING TO. AND THE CURRENT WAS SO BAD, IT KIND OF FLIPPED ME AROUND AND I GRABBED ON TO WHAT I THINK WAS THE BACK OF THE CAR AND JUST PULLED MYSELF UP AND CLIMBEDP ONTO THE TOP OF THE CAR. ASHLEY WE KNOW FROM EXPERIENCE : FLASH FLOODING CAN HAPPEN AAT MOMENT’S NOTICE AND LEAD TO DISAST.ER AND BIG DISASTERS CAN LEAD TO LONG-LASTING PROBLEMS OFHE TIR OWN. WHEN Y WOUALK DOWN THE STREETS OF MILLVALE ON A RAINY AFTERNOON , YOU GET AN EERIE FEELING. >> IF YOU WERE TO GO BACK IN METI TO FRIDAY, SEPTEMBER 17, 2004, AT THIS TIME OF DAY, RIGHT WHERE WE ARE WALKING, WE WOULD BE UP TO OUR NECKS. ASHLEY JIM BURN WAS THE MAYOR OF : MILLVALE WHEN A BIGGER DISASTER, HURRICANE IVAN, HIT MORE THAN 15 YEARS AGO. >> I WAS IN MY 11TH YEAR AS MAYOR WHEN THE FLOOD HIT. WHAT YOU SAW WAS 11 YEARS OF INFRASTRUCTURE BUILDING, 11 YEARS OF PROGRESS, 11 YEARS OF WORK WITHIN A MATTER OF HOURS WASHED INTO THE ALLEGHENY RIR.VE AS GIRTYS RUN OVERFLOWED ITS BANKS. ASHLEY THE REMNANTS OF THE : HURRICANE CAUSED THEOR WST FLOODS IN A GENERATION. >> YOU ARE STANDING OVER GIRTY’S RUN RITGH NOW. THIS WAS ALL METAL ACROSS HERE FOR THIS PARK, SO THE CREEK IS HEADING THIS WAY. THE WATER PRESSURE WAS SO POWERFUL THAT IT LITERALLY PEELED UP THIS PORTION OF STLEE AS IF IT WAS TIN FOIL AND ETH WATER WENT STRAIGHT INTO THESE BUILDINGS OVER HERE,N I PARTICULAR THE ATTIC RECDOR STORE. THE NEXT DAY WHEN THE SUN CAME UP IT WASN’T A TORNADO BUT IT , MIGHT AS WELL BEEN ONE. I MEAN, DEBRIS ALL OVER THE STREETS. ASHLEY: WESTERN PA IS NO STRANGER TO FODINLOG IT IN THAT YEAR, IT WAS THAT THE FOREFRONT THE SAME, EXT ACTRAGEDY HIT THE , NEIGHBORING BOROUGH OF ETNA. >> IT WAS ABSOLUTELY DEVASTATG.IN WE ACTUALLY HAD 400 HOMES FLOODED IN IVAN, WHICH IS 25% OF THE COMMUNITY. ASHLEYE TA WLKED WITH MARY ELLEN : RAMAGE. SHE MANAGES THE BOROUGH OF ETNA DESCRIBING THE FLOOD AS A GIANT WAKE UP CALL. PROJECTS TO HELP CONTROLHE T SEVERITY OF FLOODING BEGANND A TO THIS DAY HAVEN’T STOPPED. >> PENNDOT RAISED THEIR BRIDGE 18 INCS.HE WE GAVE ALLEGHENY VALLEY RAROILAD $700,000 OUT OF THE $1.3 MILLION WE HAD TO RAISE THAT BRIDGE. ASHLEY: ALONG WITH THE BRIDGES ETNA INSTALLED DEBRIS CONTROL , FACILITIES UPSTREAM IN SHALER TOWNSHIP. AND NOW WHEN YOU WALK WNDO BUTLER STREET IN THE BUSINESS DISTRICT YOU’LL NOTICE THESE , DECORATIVE GRATES. >> WE ARE JUST VERY, VERY COMMITTED. ASHLEY A MONROEVILLE MOTHER, : SHOWING SIMILAR COMMITNTME AFTER HER DAUGHTER’S NEAR-DEATH EXPERIENCE. AFTER THAT 2019 INCIDENT DOREEN , TOOK HER CONCERNS TO COUILNC FOR MONTHS EVENTUALLY MAKING , SOME PROGRESS. >> FROM THE MAYOR OF MONROEVILLE, I GOT THE GUARDILRA EXTENDED SO SHE WON’T BE ABLE TO SLIDE BACK THERE ANYMORE. THEY PUT UP THE TWO STREET SIGNS THAT S THEAY ROAD WON’T FLOOD AND THEY HAD DUQUESNE LIGHT COME AND PUT ANOTHER LIGHT CABEUSE YOU DON’T KNOW YOU ARE IN THE WATER UNTIL YOU ARE IN THE WATER. ASHLEY DESPITE THE IMPROVEMENTS : CAITLIN SAYS SHE WILL NEVER FORGET THAT DAY. >> WHEN IT RAINS I GET REALLY NERVOUS. WHEN IT REALLY RAINS, NOW I AM STARTING TO T GEMORE COMFORTABLE BUT YEAH I AM STILL SHOCKED THAT I GOT OUT OFHE T CAR. SHANNON FLASH FLOODING GETS A : LOT OF ATTENTION FROM LOCAL OFFICIALS. MI BKEUT THAT’S JUST PART OF THE : FOCUS. THERE’S SO MUCH MORE AT STAKE FOR ANREA AWITH SO MUCH INFRASTRUCTURE. SHANNON PAUL VAN OSDOL LOOKS : INTO THE PROBLEM WITMOH RE FLASH FLOODING AND OTHER WEATHER IMPACTS ON OUR INFRASTRUCTURE. PAUL WESTERN PENNSYLNIVAA IS WESTERN PENNSYLVANIA IS DEFINED : NOT JUSTHE T -- DEFINED BY WATER, NOT JUST THE THREE RIVERS BUT ALSO THE DOZENS OF STREAMS , THAT FEED INTO THE RIVS.ER WATER EVERYWHERE MAKING US THE , ENVY OF DROUGHT-RIDDEN REGIONS IN THEES WT. >> HAVING WATER IAS FUNDAMENTAL BENEFIT TO THE ECONOMY AND THE QUALITY OF LIFE. PAUL DAVID DZOMBAK HEADS THE : CIVIL AND ENVIRONMENTAL ENGINEERING DEPARTMENT AT CMU. >> SO WE ARE FORTUNATE TO HAVE WATER. WE NEED TO MANAGE WATER. PAUL MANAGING WATER IS A : STRUGGLE WHEN SKIES UPERT AND THE RIVERS AND STREAMS ARE OVERRUN. THE CONSEQUENCES CANE DE BADLY. FOUR PEOPLE DIED DURING A FLASH FLOOD ON PITTSBURGH’S WASHINGTON BOULEVARD IN1. 201 ONE VICTIM’S BODY WAS SWEPT INTO A SEWER CONDT.UI SINCE THEN THE CITY HAS , INSTALLED FLOOD GATES AND WARNING LIGHTS. BUT DZOMBAK SAYS THAT IS NOT ENOUGH. >> WE’VE ALWAYS HAD FLOODING CHALLENGES IN OUR REGIONND A THOSE ARE GROWING IN FREQUENCY AND IN MAGNITUDE. PAUL GOVERNMENT RECORDS SHOW THE : NUMBER OF SEVERE STORMS IN ALLEGHENY COUNTYOR ME THAN TRIPLED FROM THE 1980S TO THE 20S.10 EXPERTS SAY THOSE NUMBERS WILL CONTINUE TO GROW. RECEA NT PENN STATE STUDY FOUND CLIMATE CHANGE WILLEL AD TO EVEN MORE FLOODS BY THE END OF ETH CENTY.UR THE IMPACT WILL BE PARTICULAYRL SEVE IREN SMALLER TOWNS THAT LACK FLOOD CONTROL INFRASTRUCTU.RE ONE OF THE WORST HIT AREAS WLIL BE CONNELLSVILLE WHICH SUFFERED A DEVASTATING FLOOD IN 2016. THE STUDY PROJECTS THAT THE EAAR OF CONNELLSVILLE SUBJECTO T SEVERE FLOODING WILL INCREASBYE MORE THAN 50%. OTHER MON VALLEY CMUOMNIESTI WILL SEE A 25% TO 50% INCREASE IN FLOOD RISK. >> MAINTAINING SEETRTS IN A NON-FLOODED STATE, MAINTAINI STORMWATER SYSTEMS THAT ARE CAPABLE OF HANDLING FUTURE CONDITIONS, THAT’S A BIG CHALLENGE FOR US. PAUL: HEAVY RAIFRN EQUENTLY CAUSES STORMWATER AND SEWAGE TO OVERFLOW INTO THE RIVERS AND OCCASIONALLY INTO THE STREETS. THE TOTAL OVERFLOW AMOUNTS TO 9 BILLION GALLONS PER YEAR. THAT’S ENOUGH TOILET WATER TO FILLORE MTHAN 13,000 OLYMPIC SIZED SWIMMING POOLS ALCOSAN, THE ALLEGHENY COUNTY SANITARY AUTHORITY IS SPENNGDI $2 BILLION ON A 14-YEAR PROJTEC TO LIMIT OVERFLO.WS >> A SMALL TERUNNEL GOING ACROSS HERE TO CKPI UP FROM THE CREEK. PAUL MOST OF THE MONEY FOR A : 16-MILE NETWORK OF TUNLSNE THAT MAY ALSO HELP EASE FLOODING. >> ANYTHING TH'A’S DONE TO HELP KEEP WATER OUT OF THE SYSTEM IS GOING TO HELP A MULTITUDE OF ISSUES. PAUL ALCOSAN HAS EXISTING : UNDERGROUND PIPES BUT THEY ARE NOT BIG ENOUGH TO HANDLE HEAVY RAS.IN THE NEW TUNNELS WILL BE 18 FTEE IN DIAMETER AND UP TO 150 FEET BELOW GROUND. >> ONCE ALL OF THIS NEW INFRASTRUCTURE IS BLTUI WHEN WE , HAVE A WET WEATHER EVENT AND THIS PIPE FILLS UP THE REGULATOR , ALLOWS US TO MOVE THIS WATER BACK INTO A DROP SHAFT WHICH SLOWS THE FLOW DOWN, TN ITHE ENTERS THE NEW TUNNELS. PAUL THE STORMWATER WILL THEN BE : PUMPED INTO AN EXPANDED TREATMENT PLANT THAT MORE THAN DOUBLES THE CURRENT PLANT’S CAPACITY. THE WORK WILL NOT BE DONE UNTIL 2036. ALCOSAN SAYS CLIMATE CHANGE YMA FORCE THEM TO INCREASE CAPACITY. LET’S SAY SWETART GETTING MEOR RAINFALL. ARE YOU GOING TO BE ABLE TO BUILD BIGGER PIPES? >> WE’LL BE ABLE TO ADAPT INFRASTRUCTURE TO MEET THE NEEDS IF POSSIBLE, ABSOLUTELY. PAUL EXPERTS SAY PITTSBURGH’S : WEATHER ALSO IMPACTS THE AREA’S BRIDGES. THE NTSB IS STILL TRYINGO T DETERMINE THE CAUSE OFHE F TERN HOLLOW BRIDGE COLLAP.SE BUT IN ANY BRIDGE, EXPERTS SAY SNOW, RAIN AND ROAD SALT COMNEBI TO CAUSE RUST WHICH LEADS TO DETERIORATION. >> WE ARE GOING TO PAINT ALL THE STEEL. PAUL ALLEGHENY COUNTY IS : SPENDING $34 MILLION TO REHAB THE 94-YEAR-OLD CLEMENTE BRIDGE. BEFORE CONSTRUCTION BEN,GA COUNTY OFFICIALSED L "CHRONICLE" ON A TOUR OF THE BRIDGE HIGHLIGHTING THE AREAS OF , CONCERN MAINLY RUST AND LOTS , OF IT. >> THE RUST LIKE YOU SEE HERE ON THE SURFACE AND IT STARTS LAMINATING SO WE’RE TRYING TO STOP THAT, ARREST IT WHERE IT’S AT NOW AND PAINT IT SOT I DOESN’T GET ANY FURTHER. PAUL THESE IMAGES SHOW RUST ON : THE INTERIOR OF THE BRIDGE. AND THERE’S EXTENSIVE RUST BELOW THE BRIDGE DK.EC HOW DOES THAT RUST IMPACT THE SUPPORT OVER THE LONG-TERM? >> WELL YOU GET SECTION LOSS IN , THAT MAIN MEMBER AND IT GETS THINNER AND THINNER SO OVER TIME YOU’LL HAVE TO POST THE BRIDGE. PAUL THE CMELENTE BRIDGE IS : RATED FAIR BUT 175 STATE AND LOCAL BRIDGES IN ALLEGHENY COUNTY HAVE A POOR RATING REQUIRING HUNDREDS OF MILLIONS , OF DOLLARS IN REPAIRS. LOCAL OFFICIALS REALIZE EYTH HAVE A LOT OF WORK TO DO. >> WE AAS PUBLIC WHETHER IT’S , LOCAL GOVERNMENT, STATE GOVERNMENT, FEDERAL GOVERNMENT, WE NEED TO INVEST IN INFRASTRUCTURE BECAUSE IF WE DON’T WE COULD PAY A DEAR PRICE. >> STILL AHEAD ON "ROCHNICLE," THEY’RE PESTS. THEY OFTEN CARRY LYME DISEASE. AND THEY’RE MULTIPLYINGN I PENNSYLVANIA. >> PENYLNSVANIA HAS TWO TO THREE TIMES MORE CASES THAN ANY OTHER STATE AND THAT’S BEING DRIVEN BY THE WESTERN HALF OF THE STATE. >> WHY WARMING CLIMATE MEANS MORE TICS IN OUR BACKYARDS AND WHAT THE FUTURE COULD BRING. PLUS NOWHERE TO GO AFTER DECADES , IN THEIR HOME. >> YOU ARE WORRYGIN ABOUT WHAT AM I GOING TO DO, WHEN DO I HAVE TO DO IT. HOW SOON ARE THEY GOING TO WANT ME OUT OF HERE. WHERE MY GOING TO GO? >> IN THIS STREET IS NOTHE T ONLY PART OF PITTSBURGH SLIDING AWAY. THE WORK TO ANTICITEPA LANDSLIDES, "-- SHANN:NO IN ORDER TO FULLY UNDERSTAND THE PROBLEMS WE’RE SHOWING YOU TONIGHT, LIKE FLOODING, WE MUST UNDERSTANDHE T WEATHER CAUSING THEM AND HOW THAT WEATHER IS LIKELY TO LOOK DIFFERENT IN THE COMING YEARS AND DECAS.DE MIKE: WEATHER AND CLIMATE ARE DIFFERT.EN WEATHER IS WHAT’S HAPPENING RIGHT NOW. CLIMATE REFERS TO CONDITIONS IN A SPECIFIC REGION AVERAGED OVER A LONG PERIOD OF TIME. EXTREME HEAT CAN BE DEAD.LY EXPERTS BELIEVE MORE 90 DEGERE PLUS DAYS ARE ON THE WAY TO SOUTHWESTERN PENNSYLVANIA. SEVERE STORMS CAN BE DDLY.EA EXPERTS EXPECT MORE RAINFALL ALSO. >> IN PITTSBURGH THE BIG ISSUE , FOR US IS EXTREME PRECIPITATION. MI:KE RAIN, SW,NO EVEN ICE OUR , REGION GETS IT ALL, AND A LOT OF IT. PITTSBURGH SEES ABOUT 39 INCHES OF PRECIPITATION EACH YEAR. ELLWOOD CITY, BEAVER COUNTINY FEBRUARY 2022. FLASH FLOODING SENT WATER SP ILLING UP OVER THE BANKSF O CONICAL NESTING CREEK. ONE DAY LATER -- >> THIS IS WHERE IT TOOK THE MOST DAMAGE. KE:MI JARROD MATTHEWS INVITED OUR CAMERAS INSIDE AND OUTSIDE HIS HOME ALONG MCKIM WAY. >> PULLED THE STEPS ALL THE WAY AWAY FROM THE PORCH. MIKE: HE SAYS THELOOD FING KNOCKED HIS HOUSE OFF ITS FOUNDATION. >> LITTLE BY LITTLE, GET IT FIXED BACK. MIKE: LIKE MANY IN PITTSBURGH HE DOESN’T WANT TO LIVE SOMEWHERE ELSE. WHICH IS WHY HE WANTS TO RAISE HIS HOUSE ABOVE THE FLD.OO >> THIS IS BEAUTIF.UL THIS IS PARASEDI SEER. -- PARADISE HERE. >> BUT NOW WE RECOGNIZE THAT THE CLIMATE ISN’T WE SAY STATIONARY. IT’S NOT STATIONARY. IT’S CHANGING. MIKE: HE SAYS SHORT TERM TRENDS AND LONG TERM MODELS ALIGN TO PREDICT THE STEEL CITY WILL SEE MORE RAINFALL IN THE YEARS TO COME. THOSE PREDICTORS ALSO POINT TO RISING AVERAGE ANNUAL TEMPERATURES IN SOUTHWESTERN PENNSYLVANIA. MORE EXTREMELY HOT DAYS PUTS THE VERY YOUNG AND THE VERY OLIND JEOPARDY. >> WITH EXTREME HEAT, IT’S NOT JUST ANNOYING AS IT IS ANNOYING TO THE BULKF O THE POPULATION, BUT TO SOME PEOPLE IT IS LIFE-THREATENING. MIKE: A GROUP CALLED THE UONNI OF CONCERNED SCIENTISTS PREDICTS THAT BY THE MIDDLE OF THE CENTURY THE NUMBER OF 90 DEGREES DAYS PITTSBURGH SEES EVERY YEAR COULD QUADRUPLE. OUR CMU EXPERT SAYS WEATRHE TRENDS DON’T HAPPEN QUICKLY. >> BUT THEY ARE HAPPENING. YOU CAN LOOK IN THE DATA RECORD TO S IEET CLEARLY. OUR MAIN TASK AS A SOCIETY IS TO GET ABOUT THE BUSINESS OF ADAPTATION. MIKE: PITTSBURGH’S AVERAGE TEMPERATURES HAVE BEEN WARMING FOR A FEW DECADENOW.S THAT HAS LED TO AN INCREASE IN SOMETHING ELSE MANY OF US ARE FAMILIAR WITH, TIC.KS SHANNON: ASHLEY ZILKA EXPLAINS EXPERTS ARE FOCUSING ON THIS TINY EXAMPLE THAT SIGNIFIES A HUGE PROBLEM. ASHLEY: IT’S THE SIZE OF A FRECKLE BUT THAT TINY TI HCKAS , THE POTENTIAL TO CAUSE YEARS OF PAIN FOR A PERSON WHO HAS BEEN INFECTED WITH LYME DISEASE. A MAN LIKE BILL MOORE. >> I FELT LIKE MY LIFE WAS SLIPPING AWAY. ASHL:EY MOORE SAYS IN 2009 HE WAS A HEALTHY GUY, A 40-YEAR-OLD WHO HAD RECENTLY PURCHASED HIS DREAM HO.ME >> WE WOULD GO IN THE BACKYARD AND PLAY WITH THE KIDS AND IT WAS GREAT. I HAD ZERO APPRECIATION THAT IT WAS THE PERFECT HABITAT FOR TICS. ASHLEY: BUT WHAT STARTED OUT AS THE FLU TURNED INTO SOMETHING MUCH MORE SERIOUS. MOORE HAD NO IDEA HE WAS LIVING WITH LYME DISEASE FOR WHAT WOULD END UP BEING TWO YEARS. >> THE HEADACHES BECEAM CONSTANT. THEY BECAME TO THE POINT WHERE IT WAS HARD TO WK.OR I STARTED HAVING JOINT PAIN, HAD TROUBLE THINKING, BRAIN FOG. I STARTED HAVING SOME EMOTIONAL ISSUES. I WOD ULGET ANGRY, I WOULD START CRYING FOR NO REASON. ASHLEY: THE CULPRIT, AN INFECTED TICK THAT BIT HIM IN HIS BACKYARD. WE MET WITH DR. DANIELLE TUFTS IN SCHENY LEPARK TO LEARN MORE . HERER SEARCH INCLUDES TRAPPING SMALL MAMMALS AND COLLECTING TICKS. >> SO WE ARE SEEING THAT TKSIC OUT HERE IN WESTERN PENNSYLVANIA ARE INCREASING IN ABUNDANCE AND TOIN NEW LOCATIONS. WARMER WEATHER MEANS THAT HOSTS ARE SURVIVING LONGER ANDHE T HOST MAY BOMECE MORE ABUNDANT IN THE ENVIRONMENT WHICH GIVES TICKS MORE OPPORTUNITIES TO EDFE ANFINDD A HOST. IF WINTERS CONTINUE TO GET WARMER, AND IF WE KEEP SEEING THIS TREND, THEN IT’S A GOOD POSSIBILITY THAT WE WILL KEEP SEEING AN INCREASE IN LYME DISEASE. ASHL:EY WE ASKED DR. ANDREW NOWALK AT UPMC CHILDREN’S HOSPITAL WHAT HE IS PERSONALLY SEEING IN HIS PATIENTS WHO DIDN’T GET THAT TICK OFF OF THEM IN TIME. >> WE ARE THE CENTER OF THE LYME DISEASE EPIDEMIC IN THE UNITED STATES. PENNSYLVANIA HAS TWOO TREETH TIMES MORE CASES THAN ANY OTHER STATE AND THAT’S BEING DRIVEN BY THE WESTERN HALF OF THE STATE. THE PEAK NUMBER OF CASES ARE IN OUR BODAR IS -- BOYS AGES FIVE TO BUT WE SEE A LOT OF CASES NINE, ACROSS ALL OF THE AGE GROUPS AND UP TO ALMOST 1500 A YEAR NOW. ASHLEY: NOWALK SAYS THERE ARE A NUMBER OF SYMPTOMS YOU SHOULD BE AWARE OF ESPECIALLY AS TICK SEASON APPROACS.HE >> THE RASHES WE SEE WITH LYME DIASSEE WHICH TEND TO BE CIRCULAR RASHES THAT GET BIGGER OVER TIME. >> IT’S BAD NEWS. ASHLEY: AS FOR MOORE HE SAYS IT TOOK A NUMBER OF VISITS TO DOCTORS, A VISIT TO THE CLEVELAND CLINIC AND ULTIMATELY , A LYME DISEASE SUPPORT GROUP IN OHIO TO HP ELHIM GET DIAGNOSED. IT’S WHY HE BECAME MOTIVATETOD GET INVOLVED WITH THE PA LEYM RESOURCE NETWORK NOW HEADING THE , PITTSBURGH REGION. >> IT WAS PRETTY DARK FOR THEOS TWO YEARS THAT I WAS SICK. I AM ONE OF THE LUCKY I WAS ABLE ONES. TO MOSTLY RECOVER. NOT 100%, I STILL HAVE LINGERING SYTOMPMS, BUT MOSTLY I WAS AEBL TO GET MY LIFE BACK. >> IN A CITY OF SLOPES CRACKS , PUT ENTIRE COMMUNITIES ON HIGH ALERT. >>HE M TONEY NEEDED TO DO ALL THE STABILIZATION IN THE CITY JUST TO STABILIZE THE ONES WE KNOW OF IS MILLIONS OF MILONLIS IN OUR -- NOT IN OUR BUDGET. SHANNON: A VISUAL PITTSBURGHERS SEE MORE FRQUENTLY THAN THEY’D LIKE, THE LAND LITERALLY SLIDING AWAY. MI:KE THE AMOUNT OF RAIN WE’VE TALKED ABOUT TONIGHT SOFTENS THE GROUND OVER TIME WHICH ALONG , WITH OTHER CONTRIBUTING FACTORS LEADS TO THESE RECURRING LANDSLID. SHANNON: HERE’S PAUL VAN OSDOL. >> ESSENTIALLY IT SLID DOWN A FAIR AMOUNT AND THEN STOPPED. PAUL: THIS IS LANDER STREET IN FRONT OF JOE AND JENNIFER GOLLICK’S HOME IN PITTSBURGH’S ELLIOTT NEIGHBORHO.OD FOUR YEARS AGO A LANDSLIDE , CAUSED THE STREET TO CRUMBLE PREVENTING THE GOLLICKS FROM ACCESSING THEIR GARA.GE AND THAT’S NOT ALL. >> JOE HAS HEALTH PROBLEMS AND WE’VE HAD EMS UP HERE A COUEPL TIMES FOR THAT AND THEY CAN’T GET A STRETCHER TO THE HOUSE BECAUSE OF THE CONDITION OF ETH ROAD. SO THERE’S A CONCERN THAT IF WE HAD A REALLY BAD EMERGENCY WE’D HAVE TO SORT OF FEND FOR OURSELVES. PAUL: DAYS AFTER THE SLIDE CITY , OFFICIALS PROMISED TO ADDRESS THE PROBLEM. TBU IN THE FOUR YEARS SINCE -- >> ABSOLUTELY NOTHING. WHAT YOU SEE IS WHAT'’ HERE. PAUL: THE CITY’S CHIEF ENGINEER SAYS IT'S’NOT FINANCIALLY FEASIBLE TO REPAIR THE STREET. >> CAN WE JUSTIFY SPENDING WHATEVER IT MIGHT HAVE BEEN, A MILLION OR MORE DOLLARS TO FIX A STREET THAT HAD ONE HOUSE ON IT? PAUL: A SPOKESPERSON FOR MAYOR GAINEY SAYS THE CITY HAS OFFERED THE GOLLICKS $190,000 TO BUY THE PROPERTY. BUT THE GOLLICKS SAY THAT ISAR F BELOW THE APPRAISED VALUE AND DOES NOT INCLUDE MOVING COSTS. >>ES NOT INCLUDE MOVING COSTS. LET ME PUT IT THIS WAY. WHEN THIS ALL STAEDRT I HAD BROWN HAIR. I HAVE ALL GRAY HAIR NOW. IT’S STRESSFUL. IT IS EXTREMELY STRESSFUL. UL:PA LANDSLIDES HAVE BEEN STRESSING OUT PITTSBURGHERS FOR DECADES FROM EAST PITTSBURGH TO , MOON TOWNSHIP TO MNTOU WASHINGTON TO THE NORTH LLHI A TOTAL OF ABOUT 200 LANDSDESLI IN ALLEGHENY COUNTY OVER THE PAST DECADE, ACCORDING TCOO UNTY RECORDS. THIS MAP SHOWS LOCATIONS OF ALL THE COUNTY’S LANDSLIDES. WHY SO MANY LANDSLIDES IN WESTERN PA? PITT GEOLOGIST DAN BAIN YSSA WHEN YOU COMBINE STEEP HILLSIDES DAN CLAY SOIL WITH RAIN AND SNOW YOU’VEOT G TROUBLE. ,>> THESE CLAYS ARE PRETTY SLIPPY PARTICULARLY WHEN YOU GET IT W.ET WITH THE STEEP SLOPES,HE T WETNESS AND THE UNDERLYING ARCHITECTURE OF THE BEDROCK YOU TEND TO START TO PUSH WATER OUT ONTO THESE SLOPES. PAUL:HE T RESULT COLLAPSING , ROADS LIKE EL PASO STREEINT PITTSBURGH’S STANTON HEIGHTS NEIGHBORHOOD. >> GETTING TO MY HOUSE IAS SAFETY ISSUE. PAUL: HOMEOWNER DONNA SOMMER SAYS WHEN IT SNOWS S PHEANICS. IF THIS ROAD IS ICY WH'A’S GOING THROUGH YOUR MIND? I’M NOT GOING DOWN IT. I’M NOT GOING DOWN. I’M NOT GOING TO EVEN TRY COMING DOWN THE SIDE BEUSCAE WHAT’S GOING TO STOP ME IN THE FRONT? NOTHING. I’M GOING OVER THE HILLSIDE, -- I’M GOING OVER THE HILLSIDE. PA:UL THE CITISY SPENDGIN 10 MILLION DOLLARS TO FORTIFY MOUNT WASHINGTON AGAINST LAND LIED BUT THE CITY SAYS FIXING ALL OF ITS LANDSLIDE PROBLEMS COULD COSUPT TO $100 MILLION. AND WITH CLIMATE CHANGE BRINGING MORE PRECIPITATION IN THE COMING DECADES OFFICIALS EXPECT THE TAB TO GROW. WHAT IS YOUR CONCERN ABOUT WHAT THAT MEANS FOR THE CITY? >> I MEAN THAT’S VERY SCARY FROM , A SLOPE STABITYLI STANDPOINT. IAS MENTIONED WATER IS THE , ENEMY OF SLOPE STABILI.TY PAUL: AND THERE’S ONLY SO MUCH ENGINEERS CAN DO TO PROTECT PITTSBURGH’S HILLSIDES OMFR INCREASING AMOUNTS OF WATER. >> I MEAN YOU COULD RING EVERY , HILLSIDE WITH MASSIVE RETAINING WALLS BUT THAT’S JUST NOT A FEASIBLE OUTCOME. >> I DON’T KNOW WHAT YOU CAN DO. DUMPING THAT MUCH WATER, WE WOULD HAVE TO ENGINEER EVERY SINGLE INCH OF THE LAND SLATE -- LANDSCAPE TO MAKE IT FAILSAFE. >> COMING UP FORECASTING OUR , FUTURE. A WARNING FROM HISTORY. >> WE HAVE HAD THE WORST FOG IN THE LAST FOUR DAYS IN THE HISTORY OF DONORA. ABOUT 18 PERSONS HAVE DIED FROM ASTHMA FROM THE FOG. >> WHY THE AIR TURNED DEADLY IN OCTOBER 1948. AND WHAT HAPPENS TODAY WHEN WEATHER CONDITIONS TPRA POLLUTION IN OUR VALLEYS. BUT FIRST, WE RETURN TO THE LOCAL COMMUNITY HIT BY AN UNEXPECTED TORNADO. NEXT ON "CHRONICLE." MI:KE -- SHANN:NO WELCOME BACK TO "CHRONICLE." TONIGHT WE ARE TALKING ABOUT , PITTSBURGH’S WEATHER AND CLIMATE AND THE IMPACT THEY HAVE ON OUR COMMUNITIES NOW AND INTO THE FUTURE. MIKE: USUALLY IN WESTERN PENNSYLVANIA TORNADOES HAPPEN , BETWEEN APRIL AND SEPTEMBER WITH THE PEAK ACTIVITY IN JUNE AND JULY. BUT NOW THEY’RE HAPPNING MORE FREQUENTLY. LIKE IN FEBRUARY 2018 WHENN A -- A TORNADO HIT UNIONTOWN. IT WAS UNPRECEDENTED. SHANNON: ASHLEY ZILKA GOES BKAC TO THE NEIGHBORHOOD THAT GOT HIT AND TURNS OUT, THE IMPACT >> PEOPLE DIDN’T KNOW WHATOT DO. THAT’S NEVER HAPPENED TO THEM BEFORE AND PROBABLY WILL NEVER HAPPEN AGAIN. ASHLEY: IT’S BEEN FOUR YEARS SINCE THE RAREOR TNADO HIT UNIONTOWN IN FAYETTE COUY.NT >> THIS HOE USHAD ROOF DAMAGE. ASHLEY: BUT FOR PEOPLE LIKE JOHN MCMAHON THE DETAILS REMAIN FRH.ES >> I HAD DAMAGE ON THE WTEHI PART OF THE PEERS. THEY HAD TO PUT THAT BACK AND YOU CAN SEE WHERE MY SIDING SPLIT. I HAD A GUY JUST COMANE D HE CUT IT AND REPLADCE THAT GOT HER WO.RK -- GOT YROU WORK -- GUTTER WORK WAS REPLACED. ASHLEY: AN EF1 TORNADO UCTOHED DOWN ON THE NIGHT OF FEBRUARY 15, 2018 WITH WINDS UP TO 105 MI LES PER HOUR. >> IT WAS FAST. I WOULD SAY LESS THAN A MINUTE. ASHLEY THE FIRST EVER RECORDED : TORNADO IN THE MONTHF O FEBRUARY SINCE 1950 WHEN THE NATIONAL WEATHER SERVICE STARTED TRACKING THEM. >> I WAS JUST HOPING NOBODY GOT HURT BUT YOU REALLY COULDN’T TELL. ASHLEY: SKY 4 VIDEO CAPTURED THE DESTRUCTION LEFT BEHIND ROOFS BLOWN TREES UPROOTED AND DEBRIS SCATTERED ACROSS YAR.DS >> I TELL YOU WHAT YOU HAVE TO , BE IN ONE AND WALK O THEUT DOOR AFTER IT HAPPENSND A AUTOMATICALLY SEE ALL THE DAMAGE. THERE WAS NO ELECTRIC BUT PEOPLE HAD FLASHLIGHTS AND EVERYTNGHI ELSE TRYING TO GET AROUND. ASHLEY: NOW FAST-FORWD ARTO PRESENT DAY. THE POWER’S BACK ON AND ETH DEBRIS HAS BEEN CLEARED BUT IF YO U DRIVE AROUND UNIONTOWN YOU’LL SEE LIFE NEVER REALLY GOT , BACK TO NORMAL FOR SOME TORNADO VICTIMS WHO MCMAHON SAYS STAYED IN THOSE RAVAGED HOMES. >> SINCE THAT HAPPENED, EY ATHRE NOT LIVABLE. THEY ARE LIVING IN IT, BUT IT’S NOT LIVABLE. ASEYHL: OR THIS PROPERTY A , PERMANENT REMINDER OF THAT NIGHT. >> SO ITOO TK THE HOUSE COMPLETELY GONE. I MEAN IT JUST PICKED IT UP AND TOOK IT AW.AY LEFT THE FOUNDATION. ASHL:EY HE CONSIDERS HIMSELF LUY CKA MAN WHO HAS LIVED IN THE , SAME HOME ON MILLVIEW STREET FOR 36 YEARS A NEIGHBORHOOD WITH A LOT OF HISTORY HE SAYS BOTH GOOD AND BAD. MIKE: SOMETHING UNIQUE TOHE T PITTSBURGH AREA IS THE IMPACT TOPOGRAPHY HAS ON AIR QUALITY. WHILE THE AIR WE BREATHE AROUND PITTSBURGH IS SO MUCH CLEANER THAN IT USED TO BE, THE AMERICAN LUNG ASSOCIATION STILL RANKS OUR AIR QUALITY AMONG THE WORST IN THE NATI.ON SHANNON: WITH REGARD TO OUR AIR QUALITY, WE CAN’T THINK ABOUT THE FUTURE WITHOUT TAKING A HARD LOOK AT THE PAST. LET’S START IN DONORA, WASHINGTON COUNTY, LATE OCTOBER, 1948. >> WE HAVE HAD THE WORST FOG IN THE LAST FOUR DAYS IN ETH HISTORY OF DONA.OR ABOUT 18 PERSONS HAVE DIED FROM ASTHMA FROM THE FOG AND ACID FUMES FROM THE ZINCOR WKS. SHANNON: AIR POLLUTION CAUSED DEATHS IN DONORA IN 1948. THE WEATHER SOMETHING CALLED A , TEMPERATURE INVERSION PUT THE , NAIL IN THE COFFIN. MORE ACCURATELY PUT THE LID ON THAT CFIOFN. THE INVERSION STARTS ON A TUESY.DA BY FRIDAY -- >> AND FIGHT -- IN FACT RIGHT , OUT HERE ON THE CORNER OF 6TH AND MCANKE, IT’S PETER STARKOVICH WHO DROPS, LITERAYLL DROPS DEAD ON THE STRT.EE SHANNON: HISTORIAN AND RETIRED TEACHER BRIACHN ARLTON WORKS SMOG MUSEUM. THEIR RESEARCH SHOWS THE TEMPERATURE INVERSION THAT HIT WESTERN PA THAT YEAR WAS PROBABLY THE LONGEST LASTING INVERSION IN THE 20TH CENTURY. THINK OF AN INVERSION AS AN ATMOSPHERIC LAYER CA.KE COOL AIR SITS ON A LAYER OF WARM AIR. THAT LAYER SITS OVER TOP ANOTHER LAR YEOF COOL AIR. WHATEVER LIES UNDER THAT LAYER CAKE CAN’T BUDGE. ESPECIALLY IN A RIVER VALLEY. UNITEDTA STES STEEL’S OPERATION IN DONORA INCLUDED A FACTORY THAT SMELTED ZINC OUT OF ZCIN ORE. THAT ZINC WAS USED TO GALVANIZE METAL. >> IF YOU LOOK AT A PHOTOGRAPH OF THE ZINC WORKS, YOU WILL SEE AROUND THE ZCIN WORKS THAT A TON OF EROSION THAT’S WHAT’S KILLING , ALL OF THE VEGETATION, THOSE GASES, AND THAT’S WHAT’S ATTACKING YOUR LUNG TISS OUEN A DAILY BASIS. SHANNON: OFFICIALLY THE DONORA , SMOG DISASTER TOOK ABOUT 20 LIVES. BRIAN CHARLTON PUTS THE NUMBER CLOSER TO 80 INCLUDING THE FATHER OF BASEBALL HALL OF FAMER STAN MUSIAL WHO TRAVELED TO HIS SON’S SAINT LOUIS HOME TO E.DI DR. CHARLES STACY, A RETIRED SCHOOL ADMINISTRATOR SURVIVED THE SMOG. HE KNOWS MANY OF HIS NEIGHBORS DID T.NO >> TOUGH COMMUNITY, EVERYBODY THOUGHT THAT THAT WAS WHATHE T WORLD WAS SUPPOSED TO BE, SMOKE AND FOG AND PEOPLE BREATHED IT IN, AND YOU ENJOYED .IT THEY ENJOYED IT BECAUSE IT WAS EMPLOYMENT. SHANN:NO THE FORECAST THE FUTURE OF SIMILAR THREATS RESEARCHERS , FOLLOW THE LOGIC A SIMPLE , EQUATION. WHEN MAN-MADE POLLUTION PLUS A NATURAL WEATHER EVENT EQLSUA DEATH ELIMINATING THE ONLY MAN , MADE THING EQUALS A BETTER SHOT AT HEALTH AND LIFE. FOLLOW THE BREEZE TO CLAIRTON. HOME OF U.S. STEEL’S CLAIRTON COKE WORKS. >> TAKE A DEEP BREATH. SHANN:NO AND HOME TO A DAYCARE CENTER WHERE CHERYL HURT TAKES CARE OF CHILDREN INCLUDING HER THREE-YEAR-OLD GREAT GRANDSON KYRE.LL >> HE HAS RESPIRATORY ISSUES, SO HE HAS TO TAKE IT EVERY SINGLE DAY TWICE A DAY. SHANNON: AN AIR MONITOR OUTSIDE GIVES HER VALUABLE INFORMATION INSIDE. >> IF THIS GOES TOO HIGH ACCORDING TO THE MONORIT, ETH CHILDREN DON’T GO OUT AND PLAY. SHANNON: AND YOU GREW UP IN AICLRTON? >> BORN,. -- BORN, RAISED, REARED. SHANNON: YEARS AGO, SHE WORKED IN THE MILL. TODAY SHE WATCHES THE SMOKE STACKS FROM HER FRONT WIND.OW >> THE AIR QUALITY HERE IS BA}.) SHANNON: THAT’S NOT JUSTER H OPINION. >> WE FOUND THAT 22% OF THE CHILDREN HAVE PHYSICIAN DIAGNOSED ASTHMA, THAT’S TWO TO THREE TIMES WHAT WE EXPECT IT TO BE BASED ON THE COUNTY, STE,AT AND NATIONAL PREVALENCE RATE. SHANNON: DR. DEBORAH GENTILE PUBLISHED A STUDY ON ASTHMA RATES IN CLAIRTON. 74 YEARS AFTER THE DONORA SMOG DISASTER WEATHER AND POLLUTION CONTINUE TO COLLIDE IN WESTERN PA. >> I THINK, WHAT ARE WE BREATHING? ATTH’S WHAT I THINK, WHAT ARE WE DOING BREATHING? SHANNON: AIR QUALITY MONITORS STATIONED AROUND THE MON VALLEY ANSWER THAT QUESTION EVERY DAY. WHILE MOST AMERICAN CITIES HAVE GOTTEN INTO COMPLIANCE WITH AIR QUALITY STANDARDS IN THE PAST TEN YEARS, THE PITTSBURGH REGION JUST ACHIEVED COMPLIANCE FOR THE VERY FIRST TIME. NOW THE CLEAN AIR GOAL LINE MAY , BE SOON MOVING FURTHER DOWN THE FID.EL ETH CURRENT ALLOWABLE MAXIMUM AMOUNT OF PARTICULATE OR FINE POLLUTION IS 12 MICROGRAMS FOR EVYER METER CUPID. -- ERYVE METER CUBED. THE EPA IS CONSIDERING LOWERING THAT TO 10 OR EVEN 8. THE WORLD HEALTH ORGANIZATION RECOMMENDS LOWERING THAT PARTICULATE NUMBER ALL THE WAY TO 5. WHILE GOVERNMENT AND INDUSYTR BATTLE ABOUT POLLUTION RULES, CHERYL HURT WATCHES THE SMOKE STACKS AND THE WEATHER. >> I WANT US TO BE ABLE TO BREATHE. WE DESERVE TO BE ABLE TO BREATHE. >> STILL AHEAD ON "CHRONICLE KUNCO WADING INTO A POCKET OF WILDERNESS INSIDE THE CITY. >> SO MUCH OF THE FLOODING ISSUES ARE CAUSED BY INAPPROPATRIE LAND USE. >> MEET THE WOMAN SPEAKINGP U FOR PITTSBURGH WATERWAYS. AND THEN, HE WANTS TO HELP PITTSBURGH BUILD GREENER COMMUNITIES. SHANNON: DO YOU THINK ABOUT YOUR GRANDCHILDREN? >> YEAH, YEAH, IT WORRIES ME, CLIMATE CHANGEOES DWORRY ME. >> THE LALOC LEADERS AND INNOVATORS SOLVING PROBLEMS POSED BY A WARMER FUTURE. MIKE: WHEN YOU THINK OF PITTSBURGH, YOU THINK OF RIVS.ER WHEN STORMS HIT HARD AND FT WITH HEAVY RAIN, PITTSBURGH’S CREEKS, STREAMS, AND TRIBUTARIES BEAR THE INITIAL BRU ONTF THE FLOODING AND DAMAGE. SHANNON: AS THE HEALTH AND SUSTAINABILITY OF OUR STREAMS GO, SO GOES OUR RIVERS. I GOT A VERY CLOSE LOOK AT ONE OF PITTSBURGH’S WATEAYRWS, WITH A WOMAN WHO CARES A GREAT DEAL ABOUT FORECASTING ITS FUTURE. A PIECE OF PITTSBURGH SO SELDOM SEEN THAT IT’S LLCAED SELDOM SEEN PK.AR BACK BEHIND THE SALT DOME ON SAW MILL RUN BOULEVARD IN PITTSBGHUR’S BEECHVIEW NEIGHBORHOOD. >> WE ARE PRIMARILY FOCUSED ON WHAT’S HAPPENING IN SAW MILL DAN WHAT WE CAN DO TO CRTEEA POLITICAL WILL FOR CHANGE AND TRANSFORMATION. SHANNON: LISA WERDER BROWN, THE DIRECTOR OF WATERSHEDS OF SOUTH PITTSBURGH LEADS STREAM WALKS. >> URBAN STREAM WALKS ARE A RARITY. SHANNON: SHE SAYS THE SAMIW LL RUN IS IN TROUBLE. >> YOU DON’T WANT TO TOUCH THE WATER. SHANN:NO REAY?LL >> IT’S NOT, THERE’S A LOT OF BACTERIA IN THIS WAT.ER SHANNON: SHE SAYS THIS STREAM’S PROBLEMS GO BEYOND POLLUTION. >> SO MUCH OF THE FLOODING ISSUES ARE CAUSEBYD INAPPROPRIATE LAND USE. SHANNON: SHE SHOWED ME A STUDY COMMISSIONED BY THE CITY OF PITTSBGHUR IN TO GET ADVICE ON 1910 ALL THEAJ MOR TRAFFIC ROUTES IN AND AROUND THE CITY. FREDERICK LAW OLMSTED CAME BACK TO THE CITY PLANNERS AND SAID UNDER NO CIRCUMSTANCE SHLDOU THEY ALLOW DEVELOPMENT ALONG THE SAW MILL RUN. HE SAID THE LAND ALONG THE WATERWAY SHOULD BE A LONG LINEAR PARK. PITTSBURGH’S LEADERS DIDN’T LISTEN. >> BUT MOST OF WHAT WE HAVE ALONG HERE IS USED CAR LOTS, WHICH IS ESSENTIALLY A PARKING LOT. SOOU Y HAVE ALL THIS PAVEMENT. SHANNON: TOO MANY IMPERVIOUS SURFACES LEAD TO FLOODING IN STREAMS AND CREE.KS SHE URGES PITTSBURGH AND THE SOUTH HILLS SUBURBS TO COMMIT TO A PLAN TO FIX THE STREAM. THE PITTSBURGH WATER AND SEREW AUTHORITY’S STORM WATER MANAGEMENT TEAM LED BY ENGINREE TONY IGWE SAYS THEY’RE WORKING ON IT. THEY STARTED REHABBING THE BANKS OF THE SAW MILL RUN ADDING , BOULDERS AND PIPES CAREFULLY DESIGNEDO TREDUCE FLOODING. >> LIKE MOST CITIES INHE T MIDWEST AND NORTHEAST, WE'V’ DEFERRED A LOT OF INFRASTRUCTURE REPAIRS THAT WE SHOULD HAVE BEEN DOING, SO THE BIGGEST CHALLEENG REALLY IS JUST CATCHING UP. SHANNON: PWSA USED TO BASE YOUR WATER BILL ON HOW MUCH YOU RAN YOUR TAPS. IF YOU’RE A PWSA CUSTOMER YOU’LL ALSO NOTICE A NEW FEE ON THE HARD SURFACES OF YOUR PROPERTY LIKE PATIOS AND DRIVEWAYS. THEY SAY THAT’S A BETTER MEASURE OF HOW MUCH EACH WATER CUSTOMER IS CONTRIBUTING TO THE STORM WATER CHALLENGANE D PROVIDES A DIRECT WAY TO PAY FOR THE FIX. >> THERE WAS A TIME WHERE IT WAS POPULAR FOR POLITICIANS TO SAY NO NEW TAXES, YOU’RE NOT GNGOI TO GET ANY INCREE.AS WELL, THATAS W BASICALLY THEM SAYING WE’RE NOT GOING TO DO THE , MAINTENANCE THAT WE NEED, WE’RE NOT GOING TO DO THE UPGRADES, WE’RE GOING TO CKKI THE CAN DOWN THE ROAD. THIS IS DOWNHE T ROAD. SHANNON: WERDER BROWN SAYS NEW ZONING LAWS SHOULD REQUIRE DEVELOPERS BUILDING NEAR STREAMS TO MAINTAIN THEM AND REQREUI THEM TO REPLACE SOME HARD SURFACES WITH GREEN SPE.AC THE PROBLEMS AND POLLUTIONF O THE PAST FLOW DOWNSTREAM FROM A SMALL AND SELDOM SEEN CITY WATERWAY ALL THE WAY TO PITTSBURGH’S ROLLING RIVERS. THAT MEANS WHEN THE SAW MILLUN R GETS HEALTHIER THAT FORECASTS A , STRONGER FUTURE BEYOND ITS BANKS FOR THE MONONGAHELA, THE OHIO, AND BEYO.ND >> NT EXON "CHRONICLE" -- >>HE T FACT THAT SOME CITIES MAY BE UNDERWATER DAN UNINHABITLEAB AND THE COST TO SOCIETY, IT’S WORRISOME. >> AN UERNCTAIN FUTURE LEADING TO A LIFE-CHANGING PRESENT. HOW ONE LOCAL MAN IS RE-ADJUSTING HIS WORLD, AND THE EXAMPLE HE HOPES IT SETS FOR OTHERS. AND PITTSBURGH, GOA LDILOCKS ZO?NE WHAT ABOUT OUR WEATHER MAKES THINGS JUST RIGHT ACCORDING TO EXPERTS, WHEN "CHRONICLE" CONTINUES. SHANNON: WE MUST ADAPT. IT’S A SSMEAGE WE HEARD OVER AND OVER AS WE REPORTED THE STORIES WE’RE TELLING TONIGHT. MI:KE AND THERE’S WORK ALREADY UNDERWAY TO ADAPT TO CHANGING CONDITIONS AND HELP SOLVE SOME OF THE TOUGHEST PROBLEMS. SHANNON: WE GOT A CHANCE TO MEET SOME OF THE PITTSBURGHSER SOLVING THOSE PROBLEMS. PITTSBURGH’S INDUSTRIAL PAST PLAYED A BIG ROLE IN THE POLLUTION THAT SEEPS EVENOWN INTO CLIMATE AND WEATHER WOR -RY -- WEATHER WORRY. SOLVING THE CLIMATE ZZLEPU STARTS HERE TOO. THE PIECES OF THAT PUZZLE ARE IN OUR AIR, HOW OUR WATERWAYS FLOW, AND IN WHAT WE TAKE FROM THE GROUND. FOR THAT COME WITH ME FOR A RARE , LOOK INSIDE THE NATIALON ENERGY TECHNOLOGY LABORATORY. WE ARE NOT IN WASHINGTON, D.C. THE U.S. DEPARTMENT OF ENERGY BUILT THIS LAB IN SOUTH PARK TOWNSHIP, ALLEGHENY COUNTY 110 YEARS AGO. FOR 30 YEARS THE SCIENTISTS HERE , HAVE BEEN TRYING TO FIGURE OUT HOW TO SLOW DOWN THE FLOW OF GREENHOUSE GAS CARBON DIIDEOX INTO THE ATMOSPHERE WHEN WE BURN FOSSIL FLS. >> IN OUR BUILDINGS HERE WE ARE DEVELOPING TECHNOLOGIES TO LOWER THE COST OF REMOVING CARBON DIOXIDE FROM FLUE GAS, FROM POWER PLANTS, NATURAL GAS, OR COAL PLANTS. WE HAVE DISCOVERED THE CHARACTERIZING MATERIALS. SHANNON: DIRECTOR BRIAN ANDERSON FORECASTS ANY FUTURE FOR CARBON CAPTURE TECHNOLOGY TO HELP FIGHT CLIMATE CHANGE WILL HAVE TO HAVE AN ECONOMIC INCENTE.IV THERE IS SUPPORT FROM HIS BOSS IN THE WHITE HOUSE AND BHOT SIDES OF THE CONGRESSIONAL ALEIS TO INCREASE THE TAX INCENTESIV FOR COMPANIES WHO STORE CARBON OXIDES UNDER THE GROUND. ANDERSON AND THE SCIENTISTS HERE PRETTY EXCITED ABOUT UPCYCLING CARBON COAL WASTE AND MAKING INTO SOMETHING USEFUL AND IN SKY HIGH DEMAND. >> THIS IS THE FIRST EXAMP OFLE USING CARBON IN A COMPUTER CPHI LIKE THIS, AND MORE IMPORTANTLY USING A WASTE CARBON FROANM INDUSTRIAL PROCESS. SHANNON: AND IT’S JUST AS GOOD OR BETTER THAN WHAT’S ALREADY WIDELY ON THE MARKET? >> IT OUTPERFORMS WHAT IS CURRENTLY COMMERCIALLY AVAIBLLAE. IT IS MORE ENERGY EFFICIENT, SO IT USES LESS ENERGY TO RUN THE COMPUTER SYSTEM. IT’S FASTER WHICH MEANS IT CAN DO MORE OPERATIONS PER SECOND THAN A TRADITIONAL COMRTEPU MEMORY CHIP. SHANNON: THE WHITE HOUSE TASKED DIRECTOR ANDERSON WITH TURNING AROUND AMERICA’S FORMER CLOA COMMUNITIES, LIKE THE ONHEE GREW UP IN, IN WEST VIRGINIA. IT’S NOT A PIPE DREAM TO YOU FOR COAL MERINS WHO MAY HAVE BEEN LAID OFF FROM JOBS COULD BE MAKING SOLAR PANELS IN PENNSYLVANIA, WESTERN PENNSYLVANIA? >> NOT JUST SOLAR PANELS. SOLAR PANELS, COMPONENTS OF A WIND TURBINE, RARE EARTH ELEMENTS THAT GO INTO THE PERMANENT MAGNETS OF WIND TURBINES, OR BATTERIES THAT GO INTO ELECTRIC VEHIES.CL SHANN:NO HOW MUCH MORE EVOLVED ARE THESE? WE LEAVE THE FEDERAL LABORATORY TO LEARN THAT THE MARKET FOR THOSE SOLAR PANELS IS HEATING UP ACROSS ALLEGHENY COUNTY TO THE NORTH BILL SPOHN LIVES IN A HOME , WITH NO NATURAL GASIL BL, EVERYTHING ON THE PROPERTY IS ELECTR.IC AND VIRTUALLY NO ELECTRICITY BILL THANKS TO NET METERG.IN HIS PROPERTY MAKES ITS OWN PEROW FROM THE SUN. >> WHEN WE OVEGER-NERATE WE GET TO USE THOSE ENERGY UNITS, THEY’RE CALLED KILOWATT HOURS, THEY’RE KEPT IN A BANK IN THE UTILITY, SO WE CAN DRAW ON TMHE WITHOUT HAVING TO PAY FOR IT. >> -- SHANNON: OUR FUTURE FORECAST MOTIVATES HIM. DO YOU THINK ABOUT YOUR GRANDCHILDREN? >> YEAH, YEAH, IT WORRIES ME, CLIMATE CHANGE DOES WORRY ME. SHANNON: HIS MESSAGE TO THE AVERAGE HOMEOWNER DON’T BE , INTIMIDAD.TE LEARN ABOUT THE SYSTEMS IN YOUR HOME AND WHEN IT’S TIME TO REPLACE THEM MAKE ENERGY EFFICIENCY PART OF YOUR UPGRADE. MAYBE YOU’RE CONSIDERING GOING SOLAR AT YOUR HOME. IF THAT’S NOT AFFORDABLE RHTIG NOW MAYBE TRIPLE PANED WINDOWS E. AND MORE STRATEGIC INSULATION, SOMETHING CALLED A DERMAL JACKET. >> YOU CAN THINK OF IT IS IF YOU WORE A PKAR OUTSIDE BUT YOU HAD THE BOTTOM WIDE OPEN BUT THE WIND WAS BLOWING AND THE AIR COULD MOVE THROUGH IT, YOU WOULDN’T FEEL VERY WARM AT ALL. BUT IF YOU TUCKED THAT INTO YOUR PANTS AND YOU AIR SEALED IT AND YOU MADE A BARRIER FROM THE AIR MOVING THROUGH IT, YOU WOULD ACTUALLY START TO FEEL THAT WARMTH BUILD UP AND FEEL A LOT WARMER. SHANNON: IF YOU THINK YOU CAN’T DO ANYTHING TO HELP SLOW DOWN CLIMATE CHANGE HE WANTS TO CHANGE YOUR MI.ND >> AND I’M NOT SELLING YOU ANYTHING EXCEPT THE FACT THAT YOU CADON BETTER. SHANNON: THE SPOHN FAMILY HAS A WELL FOR WATER AND THEMAY NAGE STORM WATER RUN-OFF ON THEIR PROPER.TY THE CEO OF THE PITTSBURGH WATER AND SEWER AUTHORITY SAYS YOU CAN DO THAT TOO LIKE WHEN IT’S TIME , FOR A NEW PATIO OR DRIVEWAY. >> MAYBE YOU D'O’T NEED ALL OF THE CONCRETE. MAYBE YOU JUST NEED THE AREA FOR YOUR TIRES TO RUN ALONG DESI YOUR DRIVEWAY. SHANNON: A PERMEABLE PARKING LANE IN SHADYSIDE. SAME CONCEPT AT A PARKING LOT ALLEGHENY COUNTY’S SOUTH PARK. FIGHTING FLOODING THROUGH DESI.GN IDEAS IN AIOCT AIR, EARTH, AND WATER PULEZZ PIECES SLOWLY SNAPPING TOGETHER ASE WSEARCH FOR THE CLIMATEND A WEATHER SOLUTIONS THAT ARETILL S MISSING FROM OUR PICTURE. SOLUTIONS TO OUR CLIMATEND A WEATHER IMPACTS WILL TAKE RESOLVE FROM MORE THAN JUST OUR CIC VILEADERS. MIKE: IT WILL TAKE COMMITMENT FROM INDUSTRY AND FROM ALL OF US. STILL AHEAD ON "CHRONICLE," EXPERTS FORECASTOU STHWESTERN PENNSYLVANIA MIGHT BE JUST RIGHT FOR THE FUTU.RE FAST FORWARD 100 YEARS. WHAT COULD MAKE PITTSBURGHO S DESIRABLE? THAT’S WHEN "CHRONICLE" RETURNS. MI:KE FOR THE LAST HOUR WE’VE BEEN SOUNDING THE ALARM ABOUT POSSIBLE WEATHER AND CLIMATE PROBLEMS IN THE YEARS TO CE.OM SHANNON: BUT IT’S POSSIBLE PITTSBURGH COULD BE BETTER OFF THAN MANY AMERICAN CITIES WITHIN THE NEXT 50 TO 100 YEARS. KE:MI METEOROLOGIST BRIAN HUTTON JUNIOR EXPLAINS THE IDEA OF A GOLDILOCKS ZONE FOR THE CHANGING CLIMATE. BRIAN CLIMATE CHANGE WILL IMPACT : EACH AREA OF THE COUNTRY DIFFERENTLY. R FOPITTSBURGH, WE LIE IN WHAT SCIENTISTS DESCRIBE AS A GOLDILOCKS ZONE. >> IN SOME RESPECTS, PITTSBURGH IS A GOLDILOCKS ZONE. OUR CLIMATE IS CHANGING, BUTOT N IN AS EXTREME AND CHALLENGING WAYS AS IN SOME OTHER PARTS OF THE COUNTRY. AS I OBSERVE SOME OF THOSE AND COMMENT TO MY WIFE ABOUT IT, SHE SAID WE LIVE IN THE GOLDILOCKS ZONE. BRIAN AS THE CLIMATE CHANGES, : AND NATURAL DISASTERS BECOME STRONGER, OUR AREA WILL EXPERIENCE AN INCREASE IN OUROU MAIN NATURAL DISASTER, FLOODING. COMPARED TO STRONGER AND MORE FREQUENT HURRICANES, LONGER WILDFIRE SEASONS, AND SCORCHING HEAT WAVES, OUR AREA MISSES ETH STRONGEST BLOWS OF CLIMATE CHANGE. IN FACT, AS TEMPERATURES WM,AR OUR HARSHEST SEASON BECOMES MORE HOSPITABLE WITH LOWER SNOWFALL TOTALS, OUR GROWING SEASON LENGTHENS, AND OUR CLIMATE BECOMES MORE LIKE A CITY HUNDREDS OF MILES TO OUR SOU.TH AS PEOPLE FLEE AREAS THAT WILL SEE SEA LEVEL RISE, COASTAL FLOODING, AND OTHER NATULRA DISASTERS, PENNSYLVANIA COULD SEE AN INFLUX OF OVER 200,000 PEOP BLEY THE END OF THE CENTURY. FOR CITIES LIKE PITTSBURGH, OWH WERE BUILT TO ACCOMMODATE LARGE POPULATIONS, OUR CURRENT INFRASTRUCTURE AND MILDER CLIMATE MAY MAKE IT A DESIRABLE DESTINATION FOR THOSE LOOKING TO ESCAPE THE WORST OF CLIMATE CHANGE. WE AREN’T THE ONLY ONES WHO HAVE DISCOVERED OUR ABILITY TO BE A CLIMATE HAN.VE FELLOW RUST BELT CITIES OF BUFFALO,EW N YK,OR DULUTH, MINNESOTA, AND CINCINNATI, OHIO HAVE STARTED TO MARKET THEIR LOCATIONS AS CLIMATE HAVENS, HOPING TO ATTRACT PEOPLE AND INDUSTRY TO HELP REVITALIZE THEIR ECONOMIES AS THE CLITEMA WORSENS. FOTHR OSE OF US WHO ALREADY LIVE HERE, WE CAN EXPECT OUR FUTURE SEASONS TO BE NOT TOO T,HO AND NOT TOO COLD, BUT JUST RIGHT IN TERMS OF TEMPERATUREND A INCREASING CLIMATE THREATS. SHANNON: OUR COMMITMENT TO THE IMPACT WEATHER HAS ON THE PITTSBURGH REGION DOESN’T END TONIGHT. MIKE: FORECASTING OUR FUTURE IS A YEAR-LONG EFFORT TO BRING YOU STORIES ABOUT THE IMPACT WEATHER AND CLIMATE HAVE ON OUR AREA. WE HOPE WHEN YOU WATCH THE WKOR WE’RE DOING THIS YEAR YOU’LL THINK ABOUT YOUR PART IN FINDING SOTIS.LU WE ALSO HOPE YOU SHARE YOUR IDEAS AND STORIES WITH US. SHANN:NO ON BEHALF OF THE ENTIRE "CONHRICLE" TEAM THANK YOU FOR , JOINING US AND HAVE A GOOD NIGHT. ♪ [CAPTIONING PERFORMED BY THE NATIONAL CAPTIONING INSTITUTE, WHICH IS RESPONSIBLE FOR ITS CAPTION CONTENT AND ACCURACY.
