Climate Change May Already Be Shifting Clouds Toward The Poles

EXCERPT: The way clouds cover the Earth may be changing because of global warming, according to a study published Monday that used satellite data to track cloud patterns across about two decades, starting in the 1980s. Clouds in the mid-latitudes shifted toward the poles during that period, as the subtropical dry zones expanded and the highest cloud-tops got higher. These changes are predicted by most climate models of global warming, even though those models disagree on a lot of other things related to clouds, says Joel Norris, a climate scientist at the University of California, San Diego. "I guess what was surprising is that a lot of times we think of climate change as something that's going to occur in the future," says Norris. "This is happening right now. It's happened during my lifetime — it was a bit startling...."
Another Inconvenient Truth: It’s Hard to Agree How to Fight Climate Change

EXCERPT: By just about any measure, the movement to battle climate change has grown so large that the truths of Al Gore’s decade-old movie now seem more mainstream than inconvenient. In Paris in December, 195 nations agreed to reduce greenhouse gases. In the United States, 70 percent of Americans say that climate change is real. Pope Francis has joined the call for action. Hundreds of thousands of people have come together for climate marches in Paris and New York, and demonstrators recently held fossil-fuel protests on six continents.
“That’s what I call momentum,” Daniel R. Tishman, the chairman of the board of the Natural Resources Defense Council, said in its recent annual report. “This isn’t just the wind at our backs; these are the winds of change.” But the movement that started with a straightforward mission — to get more people to appreciate the dangers of climate change as a precursor to action — is feeling growing pains. What may seem like a unified front has pronounced schisms, with conflicting opinions on many issues, including nuclear power and natural gas, that are complicating what it means to be an environmentalist in this day and age.
The factional boundaries are not hard and fast, with groups shifting their positions as the science and waves of activism evolve. The environmental movement has always been a congregation of many voices, and some disagreement should be expected on such complex and intractable problems as saving the planet. Still, the tensions remain strong. Consider some of the biggest points of contention...
