WASHINGTON (AP) – There’s nothing like a cold snap to bring out the global-warming skepticism of President Donald Trump.

The fact that periods of extreme cold happen in a warming climate is well known by his government but Trump’s crack Sunday — “Wouldn’t be bad to have a little of that good old fashioned Global Warming right now!” — suggests that hasn’t sunk in for the president.

Over the past week and through the weekend, Trump and his team misstated the reality on myriad issues, many connected with the partial government shutdown, Trump’s proposed wall and the Russia investigation. Here’s a look: […]

TRUMP: “Large parts of the Country are suffering from tremendous amounts of snow and near record setting cold. Amazing how big this system is. Wouldn’t be bad to have a little of that good old fashioned Global Warming right now!” — tweet Sunday.

THE FACTS: Trump is suggesting, as he has done before, that global warming can’t exist if it’s cold outside. But he is conflating weather and climate. Weather is like mood, which changes daily. Climate is like personality, which is long term.

The climate is warming, which still allows for intense cold spells.

While much of the United States was frigid Sunday, that is still less than 2 percent of the world. Earth on Sunday was about 0.9 degrees (0.5 Celsius) warmer than from 1979-2000, according to the University of Maine’s Climate Reanalyzer.

The White House in November produced the National Climate Assessment by scientists from 13 Trump administration agencies and outside scientists. It amounted to a slap in the face for those who question whether climate is changing.

“Climate change is transforming where and how we live and presents growing challenges to human health and quality of life, the economy, and the natural systems that support us,” the report says.

The White House report swept aside the idea, already discredited, that a particular plunge in temperatures can cast uncertainty on whether Earth is warming. It says more than 90 percent of current warming is caused by humans: “There are no credible alternative human or natural explanations supported by the observational evidence.” [more]
