DAVID WALLACE WELLS, WELCOME TO THE PROGRAM.

THANKS.

IT'S GREAT TO BE HERE.

SO, LOOK, PANIC SEEMS TO BE THE OPERATING MOTIVATIONAL SYSTEM OF THE DAY.

WE'VE JUST HAD GRETA THUNBERG.

WE'VE HEARD WHAT SHE SAID, AND NOW YOU ARE ESSENTIALLY SAYING THE SAME THING IN A MUCH LARGER AND BIGGER, MORE SCIENTIFIC WAY.

IS IT TIME TO BE TERRIFIED?

IS IT TIME TO EMBRACE THE NIGHTMARE AND FIX IT?

I THINK THE SCIENCE SAYS THAT THE FUTURE IS GOING TO BE QUITE TERRIFYING, EVEN IF WE MOVE VERY AGGRESSIVELY ON CLIMATE.

AND SO, I ALMOST DON'T THINK IT'S A RHETORICAL QUESTION.

IT'S JUST A MATTER OF RESPONDING TO THE SCIENCE AS IT COMES OUT.

WE'RE AT ABOUT 1.1 DEGREE OF WARMING RIGHT NOW.

I THINK IT'S ALMOST CERTAIN THAT WE WILL BE UNABLE TO AVOID TWO DEGREES OF WARMING.

AT THAT POINT, MANY OF THE ICE SHEETS OF THE WORLD WILL BEGIN AN IRREVERSIBLE MELT, AND WE'LL SEE AS MANY AS 200 MILLION CLIMATE REFUGEES.

THAT'S THE U.N. ESTIMATE, NOT MINE, 200 MILLION.

WE'RE ON TRACK TO HIT FOUR DEGREES OF WARMING BY THE END OF THE CENTURY, AND IF WE GET THERE, WE'RE TALKING ABOUT $600 TRILLION IN GLOBAL CLIMATE DAMAGES.

THAT'S DOUBLE ALL THE WEALTH THAT EXISTS IN THE WORLD TODAY.

TWICE AS MUCH WAR, IMPACTS ONNING CLURKS ON THE ECONOMY, WHICH COULD BE 20% SMALLER THAN IT WOULD BE WITHOUT CLIMATE CHANGE OR POSSIBLY EVEN SMALLER THAN THAT.

SO, WE'RE HEADING INTO SOME UNPRECEDENTED CLIMATE, AND WE HAVE NOT REALLY BEGUN TO THINK ABOUT THE WAY THAT THAT WILL AFFECT HOW WE LIVE ON THIS PLANET.

OKAY, SO LOOK, YOU'VE JUST GIVEN US THESE FIGURES.

AND FOR MANY PEOPLE, IT'S QUITE SORT OF, THEY DON'T UNDERSTAND, WHAT DOES 1.5 DEGREES MEAN?

WHAT DOES TWO DEGREES MEAN?

NOBODY QUITE UNDERSTANDS THE SCOPE OF THAT.

SO, CURRENTLY, WHERE ARE WE?

AT 1.5?

A LITTLE BELOW THAT, 1.1 ABOUT, AND IT'S GOING TO GET CONSIDERABLY WORSE FROM HERE.

IF WE END UP AT FOUR DEGREES BY THE END OF THE CENTURY, CALIFORNIA WILDFIRES WILL BURNING 64 TIMES AS MUCH LAND AS THEY DID THIS PAST YEAR, WHEN THEY BURNED MORE THAN A MILLION ACRES.

THAT'S JUST ONE FIGURE, BUT EVERYWHERE YOU LOOK, EVERY ASPECT OF LIFE WILL BE TOUCHED BY THIS FORCE.
