TODAY WE DISCUSS JUST JUST HOW MUCH THE PLANET HAS ACTUALLY WARMED AND HOW CONFIDENT SCIENCE IS ABOUT THE ROOT CAUSE OF THIS WARMING. IN JUST THE PAST CENTURY, THE EARTH HAS WARMED UP BY 2 DEGREES FAHRENHEIT. >> > > MOST OF THAT OCCURRING IN THE LAST 40 YEARS. NOW, THIS MIGHT NOT SEEM LIKE MUCH, BUT OVER THE PAST 10,000 YEARS AFTER RECOUPING FROM THE LAST GLACIAL EPOCH, THE EARTH'' S AVERAGE TEMPERATURES HAVE BARELY BUDGED. THIS STABILITY ALLOWING FOR THE INCREASE OF MODERN CIVILIZATION BUT NOT ALL PARTS OF THE EARTH ARE WARMING AT THE SAME PRICE LAND IS WARMING 50% FASTER THAN THE WORLDWIDE AVERAGE MAGNIFYING DROUGHTS AND WARMTHS WAVES IN TAMPA.YEARLY TEMPERATURES HAVE BOOSTED BY 3 LEVELS WINTERS SPIKING BY 5 AS A RESULT, RECORD COLD IN THE BAY LOCATION HAS ALMOST VANISHED IN THE ARCTIC. TEMPERATURES ARE WARMING AT 3 TIMES THE INTERNATIONAL PRICE ARCTIC SEA ICE IS VANISHING. THE QUANTITY DECREASING 40 %IN SIMPLY 40 YEARS. IN TURN LESS SEA ICE AXES, A POSITIVE COMMENTS AND ACCELERATES FROZEN WARMING, ICE ON LAND, OTHERWISE KNOWN AS GLACIERS. OUR MELTING AROUND THE WORLD.TWO-THIRDS ARE ON TRACK TO VANISH BY 2100. THIS THAWING ICE CONTINUES
TO ELEVATE SEA DEGREES AND THOSE SEAS ARE ABSORBING 90 %OF EXCESS WARMTH FROM ENVIRONMENT ADJUSTMENT. THAT ' S THE EQUAL WARM OF 600,000 HIROSHIMA, NUKE DAILY.'AND THAT HEAT IS DECIMATING CORAL REEFS. SO THE PROOF IS OVERWHELMING. THE PLANET REMAINS TO WARM AT A FAST RATE, BUT DO ATMOSPHERIC SCIENTISTS REALLY SETTLE ON WHAT ' S TRIGGERING IT? THE ANSWER IS YES IN 2021, SCIENTISTS SURVEYED NEARLY 3,000 RESEARCHERS, 91 %OF METEOROLOGISTS AND 99 %OF CLIMATE SPECIALISTS CONCURRED THAT HUMAN BEINGS ARE THE MAJOR WRONGDOER DUE TO THE MELTING OF NONRENEWABLE FUEL SOURCE AND THE LAUNCH OF HEAT CAPTURING GREENHOUSE GAS POLLUTION. THE RESEARCH STUDY CONSENSUS IS EVEN STRONGER IN 2019, THE PROOF FOR MANMADE WARMING REACH THE ELUSIVE SCIENTIFIC GOLD REQUIREMENT, MEANING THERE ' S ONLY A ONE IN A MILLION CHANCE THIS WARMING COULD BE DUE TO NATURAL FLUCTUATIONS.NOW, AS LONG AS WE CONTINUE ORGANIZATION AS USUAL, THE WARM WILL KEEP UPCOMING. THE PLANET GETS ON TRACK TO ADD ANOTHER 2 TO 4 LEVELS
FAHRENHEIT IN THE COMING YEARS. > > BUT THE BIG QUESTION IS, WHAT DOES THIS MEAN FOR HUMANITY? HOW CONCERNED SHOULD WE BE? WE ' LL DISCUSS THAT NEXT THURSDAY. >> AT THE EXACT SAME TIME.
