What Is Really Warming the World?

Researchers who study the Earth’s climate create models to test their assumptions about the causes and trajectory of global warming. Around the world there are 28 or so research groups in more than a dozen countries who have written 61 climate models. Each takes a slightly different approach to the elements of the climate system, such as ice, oceans, or atmospheric...

Alaska Entering New Era for Wildfires

Alaska, the great northern frontier of America, is being reshaped by climate change. While rising temperatures are altering its character and landscape, they are also bringing the ravages of wildfires. In the past 60 years, Alaska has warmed more than twice as fast as the rest of the country, with average temperatures up by nearly 3°F. By 2050, temperatures are projected...

21 of the world’s 37 largest aquifers losing water

The Weather Channel’s new climate change messages will surprise you

The Weather Channel has gone hawkish on climate change. It has started web- and broad-casting short but blunt messages from “25 influential voices on climate change, security, energy and peace.” The “Climate 25” features former Bush Treasury Secretary Hank Paulson, who warns that failure to take strong action on climate is “radical risk taking” for our economy.

How did we get to this point, where our politics determines whether we trust scientists or not?

By Katharine Hayhoe New to Texas Tech, it was my first year as an atmospheric science professor. We’d just moved to Lubbock, the second most conservative town in the United States. A colleague asked me to guest teach his undergraduate geology course while he was out of town. The packed lecture hall was cavernous and dark. Many of the students were glued to their phones;...

Here’s what it would take for the US to run on 100% renewable energy

It is technically and economically feasible to run the US economy entirely on renewable energy, and to do so by 2050. That is the conclusion of a new study in the journal Energy & Environmental Science, authored by Stanford scholar Mark Z. Jacobson and nine colleagues. Jacobson is well-known for his ambitious and controversial work on renewable energy. In 2001 he...

This is crazy, but there is actually good news about climate change

Here’s something rare in climate reporting: a bit of good news. Or, more accurately, not disastrous news. China has long exerted an outsize role in global climate change, not simply because it’s by far the world’s leading emitter of greenhouse gas, due largely to its enormous population, its rapid growth, and its reliance on dirty coal — but also because of China’s...

The Coal Boom Choking China

Chinese miners last year dug up 3.87bn tons of coal, more than enough to keep all four of the next largest users – the United States, India, the European Union and Russia – supplied for a year. The country is grappling with the direct costs of that coal, in miners’ lives, crippling air pollution, expanding deserts and “environmental refugees”. Desire for change...

Peak Sand, Climate Change, And The Coastal Property Bubble

Taxpayers are propping up wildly-inflated coastal property values. At some point, we’ll stop doing that, and coastal property values will crash. Unless they have already crashed because Miami gets hit by its equivalent of Superstorm Sandy. Or because the smart money pulls out of coastal real estate ahead of time after realizing that our climate inaction has made the...

GOP pledges to “rein in” Obama on climate change

The Obama administration says a new federal rule regulating small streams and wetlands will protect the drinking water of more than 117 million people in the country. Not so, insist Republicans. They say the rule is a massive government overreach that could even subject puddles and ditches to regulation. Sen. Shelley Moore Capito, R-West Virginia, is promising to...

America’s Top Two Oil Companies Reject Climate Change Measures

Shareholders of ExxonMobil and Chevron — the United States’ top two oil companies — voted down proposals aimed at getting the companies to focus a little more on climate change this week. One of the proposals would have added an independent director with experience in climate change to the boards of both companies. That proposal got about 20 percent of the shareholders’...

Drought kills 12 million trees in California’s national forests

Rangers in the San Bernardino National Forest call them “red trees.” Instead of the typical deep green color, large swaths of pine trees now don hues of death, their dehydrated needles turning brown and burnt-red because of the state’s worsening drought. “Unlike back East, where you have fall colors, here it’s because the trees are dying,” said John Miller, a spokesman...

What you need to know about Hillary Clinton and climate change

It’s strange to remember how bitterly divisive the 2008 Democratic presidential primary battle was. Hillary Clinton’s and Barack Obama’s platforms and ideological positioning were awfully similar. And on the chief difference between them — Obama’s less hawkish foreign policy — the victor wiped away that distinction by appointing Clinton as secretary of state. Now Clinton...
