It’s Cold Outside. Cue the Trump Global Warming Tweet.<br />One 2009 study found that the United States saw roughly as many record highs as record lows in the 1950s,<br />but b y the 2000s there were twice as many record highs as record lows.<br />And while climate scientists expect that the world could warm, on average, roughly 2 to 7 degrees Fahrenheit by the end of the century<br />— depending on how quickly greenhouse-gas emissions rise — they don’t expect that to mean the end of winter altogether.<br />In announcing that the United States would withdraw from the agreement among almost 200 nations to collectively<br />rein in greenhouse-gas emissions, Mr. Trump lobbed a similar charge that the deal put a burden only on America
