DEGREES THING. IT IS HARD FOR PEOPLE TO IT IS HARD FOR PEOPLE TO UNDERSTAND BECAUSE YESTERDAY WAS UNDERSTAND BECAUSE YESTERDAY WAS SEVERAL DEGREES WARMER THAN IT SEVERAL DEGREES WARMER THAN IT WAS. WAS. TODAY WHERE I AM. TODAY WHERE I AM. THIS TWO DEGREES CELSIUS THIS TWO DEGREES CELSIUS THRESHOLD. THRESHOLD. THE WASHINGTON POST ANALYZED THE WASHINGTON POST ANALYZED DATA FOUND THAT SEVERAL SECTIONS DATA FOUND THAT SEVERAL SECTIONS IN THE UNITED STATES EXPERIENCED IN THE UNITED STATES EXPERIENCED THE 2 DEGREES WARMING. THE 2 DEGREES WARMING. HELP PEOPLE UNDERSTAND WHAT DOES HELP PEOPLE UNDERSTAND WHAT DOES IT MEAN? IT MEAN? WE CROSS THE THRESHOLD OR DO WE WE CROSS THE THRESHOLD OR DO WE COME BACK FROM IT OR CAN WE FIX COME BACK FROM IT OR CAN WE FIX IT? IT?>>YES, TO PROVIDE>>YES, TO PROVIDE SOME PERSPECTIVE HERE, TWO SOME PERSPECTIVE HERE, TWO DEGREES SOUNDS LIKE A MAUL DEGREES SOUNDS LIKE A MAUL INCREASE IN TEMPERATURE, BUT INCREASE IN TEMPERATURE, BUT THAT’S THE DIFFERENCE BETWEEN A THAT’S THE DIFFERENCE BETWEEN A HEALTHY PERSON AND SOMEBODY HEALTHY PERSON AND SOMEBODY SUFFERING A FEVER, BECAUSE IT’S SUFFERING A FEVER, BECAUSE IT’S SYSTEMIC.

THE EARTH IS SUFFERING A FEVER. AND WHAT MIGHT SOUND LIKE A AND WHAT MIGHT SOUND LIKE A MODEST WARMING OF TWO DEGREES MODEST WARMING OF TWO DEGREES CELSIUS — A LITTLE LESS THAN CELSIUS — A LITTLE LESS THAN FOUR DEGREES FAHRENHEIT — FOUR DEGREES FAHRENHEIT — CORRESPONDS TO A MAJOR MELTING CORRESPONDS TO A MAJOR MELTING OF THE ICE SHEETS, INCLUDING OF THE ICE SHEETS, INCLUDING GREENLAND. GREENLAND. WE JUST SAW LAST MONTH — THE WE JUST SAW LAST MONTH — THE MONTH OF JULY — 200 BILLION MONTH OF JULY — 200 BILLION TONS OF ICE MELTED FROM TONS OF ICE MELTED FROM GREENLAND, ENOUGH TO RAISE SEA GREENLAND, ENOUGH TO RAISE SEA LEVELS BY HALF A MILLIMETER. LEVELS BY HALF A MILLIMETER. THAT MIGHT SOUND SMALL, BUT IT’S THAT MIGHT SOUND SMALL, BUT IT’S LARGE ENOUGH THAT THE HUMAN EYE LARGE ENOUGH THAT THE HUMAN EYE CAN ACTUALLY SEE IT. CAN ACTUALLY SEE IT. SO, WE CAN ACTUALLY SEE THE SO, WE CAN ACTUALLY SEE THE AMOUNT OF SEA LEVEL RISE THAT AMOUNT OF SEA LEVEL RISE THAT HAPPENED BECAUSE OF THE HAPPENED BECAUSE OF THE EXCESSIVE HEAT IN GREENLAND. EXCESSIVE HEAT IN GREENLAND. WE SAW EXCESSIVE HEAT HERE IN WE SAW EXCESSIVE HEAT HERE IN THE NORTHEASTERN U.S., IN THE NORTHEASTERN U.S., IN EUROPE. EUROPE. SO, WHAT MIGHT SOUND LIKE A SO, WHAT MIGHT SOUND LIKE A MODEST AMOUNT OF WARMING MODEST AMOUNT OF WARMING CORRESPONDS TO AN INCREASE IN CORRESPONDS TO AN INCREASE IN THE SEVERITY OF THESE MAJOR HEAT THE SEVERITY OF THESE MAJOR HEAT WAVES, THE MELTING OF THE ICE WAVES, THE MELTING OF THE ICE SHEETS, THE RISE IN SEA LEVEL, SHEETS, THE RISE IN SEA LEVEL, AND A WHOLE HOST OF AND A WHOLE HOST OF UNPRECEDENTED EXTREME WEATHER UNPRECEDENTED EXTREME WEATHER EVENTS THAT WE HAVE SEEN PLAY EVENTS THAT WE HAVE SEEN PLAY OUT IN RECENT YEARS, OUT IN RECENT YEARS, UNPRECEDENTED FLOODS AND UNPRECEDENTED FLOODS AND WILDFIRES AND SUPERSTORMS AND WILDFIRES AND SUPERSTORMS AND HEAT WAVES.
