Geoengineering our planet to solve climate change is one of the riskiest propositions humanity has ever considered. That’s largely because there’s no way to know all the consequences that come with reflecting sunlight back into space, particularly when it comes to the agricultural system that has allowed humanity to…

After hinting that it would roll back clean vehicle regulations last month, the Trump administration made it official on Thursday. It announced it would be putting Obama-era fuel-efficiency standards on hold and moving to replace them with watered-down regulations.

Noted craver of “the cleanest air” Donald Trump has finally nominated a science advisor. It’s the longest the post has remained vacant since its was created under law in 1976 (the post has been around since 1941).

To fix climate change, everything has to change. This much is true and known. But new research out in Nature Climate Change this week shows how tall the task is in particularly stark terms.

It’s not every day you learn Congressional Republicans are excited to pass an Obama-era climate deal, but that seems to be the case when it comes to a treaty that would eliminate an obscure but potent greenhouse gas.

The Group of Seven (G7) summit in Canada is going to be winnowed down the Group of Six because Donald Trump’s fee-fees are hurt. According to CNN, the White House announced Thursday the president will be packing up his toys and leaving the gathering of world leaders before its conclusion on Saturday, cutting out on…

Everyone seems to be tiring of Scott Pruitt’s many scandals, but now it seems people are even getting sick of his crappy policies. A group of 103 Congress members that includes Republicans sent a letter on Thursday to asking the Environmental Protection Agency (EPA) administrator to kill a rule he proposed that would…

Most of us (understandably) associate NASA with rockets and space exploration, but the space agency also keeps an eye on our home planet. And it turns out the public is more supportive of NASA’s efforts to monitor Earth’s ever-warming climate than you might expect.

Just over a year after President Trump’s announcement that the U.S. will jettison the Paris climate deal, Hawaii has set the most ambitious climate goal of any state: carbon neutrality in just 27 years.

California announced a sweeping rooftop solar mandate earlier this month. The first-in-the-nation policy will require all newly-constructed homes and small apartments to have solar panels on their roofs starting in 2020.

Florida Senator Bill Nelson is none too happy that the Trump administration got away with killing NASA’s Carbon Monitoring System (CMS). And it seems he won’t let the program go down without a fight.

Move over, California, there’s a new climate heartthrob state in town. After years of backward climate policies under Chris Christie’s leadership, the Garden State’s new governor Phil Murphy is overseeing a rapid transformation.

Geoengineering is a radical climate change response that could backfire catastrophically. If it did, developing countries would bear the brunt of the burden, both in terms of any negative consequences of planet-hacking, as well as if we suddenly stopped. So it stands to reason that just maybe, those countries should…

There’s been a partisan split on climate change among Americans for a while now. But a new Gallup poll shows that the gap is growing. At the same time, Americans (those who believe in climate change, at least) have never been more sure global warming will pose a risk in the near(ish) future.

On Friday, Congress passed a 1.3 trillion dollar spending bill that, among other things, will continue to enshrine the controversial notion that biomass fuels are carbon neutral. The day before, a prominent ecologist penned an article in a prestigious journal explaining why that’s baloney.

It may not include everything on environmentalists’ wish lists, but a $1.3 trillion spending bill just released by Congress spares climate and energy research programs that President Donald Trump envisioned gutting.

The Trump era is unlikely to be known for aggressive climate action, but there is one front on which scientists, engineers, and policymakers may yet make a little progress over the next few years: carbon capture technology.

On Tuesday, Environmental Protection Agency chief Scott Pruitt got an earful about his decision to repeal the Clean Power Plan from a group of 233 mayors representing more than 51 million Americans. The group submitted a letter asking Pruitt to stop with all this repealing the Clean Power Plan nonsense.

This has been the year of “drill, baby, drill” and record renewable energy numbers, science denial and increasingly dire warnings, insane wildfires and unfathomable deluges. Competing narratives are nothing new, but it increasingly feels like an existential struggle centered on climate change is underway, with…

The wildly unpopular GOP tax bill, which is expected to pass through Congress along party lines imminently, includes a number of provisions that have big ramifications for the climate and the environment. These range from mostly good (preserving solar and wind tax credits) to actually the worst (drilling in the Arctic…
