Here we go again. One of the favorite gambits of climate skeptics and deniers is to roll out the old chestnut that if the weather is cold outside your door, then global warming (emphasis here on “global”) must be fake news. You would think that anyone playing golf in sunny Florida and commenting on the cold snap in the Northeast would grasp the basic idea. But apparently not. Hence the latest dispatch from the tweeter-in-chief calling for some “good old global warming.”

Putting the concept in terms that even President Trump might understand, Jon Foley, executive director of the California Academy of Sciences, observed, “There is still hunger in the world, even if you just had a Big Mac.”

The map above makes the same point, using science rather than a metaphorical cheeseburger. It shows all of the places in the world that were experiencing above-average winter temperatures during the current cold spell in the eastern U.S. “Nobody ever said winter would go away under global warming, but winter has become much milder and the record cold days are being far outnumbered by record warm days and heat extremes,” Matthew England, a climate scientist from the University of New South Wales, pointed out. “Climate change is not overturned by a few unusually cold days in the U.S.”

In the face of such willful ignorance on the part of the American president, it would be easy to pull up close to the fireplace, take a slug or two of Wild Turkey, and write off the future. But, in fact, Trump’s extreme views on climate change are a reason for hope, not despair. His obstinate refusal to acknowledge the reality of climate change has mobilized citizens and their leaders across the globe.

The U.S. withdrawal from Paris, in particular, has energized American corporations, higher education institutions, faith-based organizations, mayors, and governors to take action. Projects for carbon-cutting and green energy at the local and state levels are making every effort to close the gap created by the White House’s insistence on treating the urgent need to reduce greenhouse gas emissions as a hoax. The most prominent coalition emerging since the withdrawal expresses this determination with eloquent conciseness: “We Are Still In.”

Developing countries, too, are recognizing the foolhardiness of President Trump’s stance and are ramping up the production of renewable energy at unprecedented rates. As a recent New York Times article noted recently, “China has indeed moved dramatically on climate change,” seeking to meet its own pledge under the Paris accord to cap carbon emissions by 2030, to launch the world’s largest carbon market, and rapidly expand the use of electric cars.

So, as the clock winds down on 2017, we should turn to 2018 with a renewed commitment to engage in unrelenting local action and national resistance, understanding that Trump is the weather and we are the climate. Best wishes for the new year.
