WASHINGTON – President Donald Trump‘s description of the local weather on planet Earth doesn’t fairly match what knowledge present and scientists say.
In an interview with Piers Morgan airing Sunday on Britain’s ITV Information, the president mentioned the world was cooling and warming on the similar time and that claims of melting ice caps haven’t come true.
TRUMP: “There’s a cooling, and there’s a heating. I imply, look, it used to not be local weather change, it was world warming. That wasn’t working too properly as a result of it was getting too chilly everywhere.”

Ten completely different local weather scientists contacted by The Related Press mentioned the president was not correct about local weather change. Rutgers College local weather scientist Jennifer Francis responded in an electronic mail: “Clearly President Trump is counting on various info to tell his views on local weather change. Ice on the ocean and on land are each disappearing quickly, and we all know why: rising greenhouse gases from burning fossil fuels that entice extra warmth and soften the ice. ”
THE FACTS: The world hasn’t had a cooler than common yr since 1976 and hasn’t had a cooler than regular month because the finish of 1985, in keeping with greater than 135 years of temperature information stored by NASA and the Nationwide Oceanic and Atmospheric Administration.
The final 4 years have been the 4 hottest years on report globally, with 2010 the fifth hottest yr, in keeping with NOAA. Yearly within the 21st century has been at the least three quarters of a level (zero.four levels Celsius) hotter than the 20th century common and within the high 25 hottest years on report, NOAA information present.

And whereas chunk of america had a frigid snap not too long ago, many of the remainder of the world was far hotter than regular, in keeping with temperature information.
Zeke Hausfather of the Berkeley Earth temperature monitoring program – initially funded by non-scientists who doubt that the world is warming – mentioned in an electronic mail: “The world has been warming steadily over the previous 50 years, with 17 of the previous 18 years being the warmest since information started within the 1850s. It’s not correct to say that the local weather has been ‘cooling in addition to warming’.”

TRUMP: “The ice caps have been going to soften, they have been going to be passed by now, however now they’re setting information. They’re at a report degree.”
THE FACTS: It is a little more nuanced, however not fairly proper.
Whereas a small variety of specialists a decade in the past had predicted that Arctic could be freed from summer time sea ice by now, most mainstream scientists and the United Nations’ Intergovernmental Panel on Local weather Change didn’t, as a substitute they mentioned Arctic sea ice would shrink, which it has, mentioned Pennsylvania State College ice scientist Richard Alley. Most scientists, together with the director of the Nationwide Snow and Ice Knowledge Middle, are predicting that the Arctic will probably be freed from summer time sea ice someday across the 2040s.

The Arctic set a report for the bottom quantity of sea ice within the winter, when sea ice often grows to its most ranges, in March 2017. In 2012, the Arctic set a report for lowest sea ice ranges. Sea ice recovered barely from that report and in 2017 in September, the annual low was solely the eighth lowest on report, in keeping with the Nationwide Snow and Ice Knowledge Middle. However the 10 lowest years of sea ice have been all within the final 11 years. Arctic sea ice is declining at a fee of 13.2 per cent per decade, in keeping with NASA.

Princeton College local weather scientist Michael Oppenheimer mentioned the Antarctic sea ice pack, much less instantly influenced by world local weather change, varies from yr to yr. Antarctica hit a report low for sea ice in March 2017, the identical month the Arctic hit a report winter low. Antarctic sea ice additionally reached a report excessive in 2014.
“Each of the big ice sheets of Greenland and Antarctica are shedding a whole bunch of billions of tons of ice per yr. Sea ice continues to say no considerably within the Arctic decade by decade, and the thickness of Arctic ice is now lower than 50 per cent of what it was 40 years in the past,” Nationwide Snow and Ice Knowledge Middle scientist Ted Scambos mentioned in an electronic mail.
