In 4 days, a river that had flowed for millennia disappeared

The latest consequence of climate change is rivers “pirating” each other’s water. Nearly a year ago, scientists noticed that the water level of the Slims River in British Columbia was extremely low. So they hopped into a helicopter and flew upstream to investigate. What they found startled them: A second, more powerful river, the Kaskawulsh, had stolen the Slims River’s...

Artist’s brilliant National Park posters advertise a grim future

Drawing upon the WPA’s classic National Parks posters, Hannah Rothstein’s new series envisions our natural treasures ravaged by climate change. With a wry and poignant twist, artist Hannah Rothstein has reimagined the great WPA posters once used to lure visitors to the splendors of U.S. National Parks. Where the original might have promised Yellowstone’s campfire...

Great Barrier Reef: Two-thirds damaged in ‘unprecedented’ bleaching

Unprecedented coral bleaching in consecutive years has damaged two-thirds of Australia’s Great Barrier Reef, aerial surveys have shown. The bleaching – or loss of algae – affects a 1,500km (900 miles) stretch of the reef, according to scientists. The latest damage is concentrated in the middle section, whereas last year’s bleaching hit mainly the...

Coal Companies Ask Trump to Stick with Paris Climate Deal

Some big American coal companies have advised President Donald Trump’s administration to break his promise to pull the United States out of the Paris Climate Agreement — arguing that the accord could provide their best forum for protecting their global interests. Remaining in the global deal to combat climate change will give U.S. negotiators a chance to advocate...

Scientists made a detailed “roadmap” for meeting the Paris climate goals. It’s eye-opening.

Back in 2015, the world’s governments met in Paris and agreed to keep global warming below 2°C, to avoid the worst risks of a hotter planet. For context, the planet’s warmed ~1°C since the 19th century. One problem with framing the goal this way, though, is that it’s maddeningly abstract. What does staying below 2°C entail? Papers on this topic usually drone on about a...

Trump’s big new executive order to tear up Obama’s climate policies, explained

This is it. The battle over the future of US climate policy kicked off in earnest today. In a sweeping new executive order, President Trump has ordered his Cabinet to start demolishing a wide array of Obama-era policies on global warming — including emissions rules for power plants, limits on methane leaks, a moratorium on federal coal leasing, and the use of the social...

Clean energy employs more people than fossil fuels in nearly every U.S. state

Trump’s upcoming executive order meant to boost fossil fuel jobs may end up harming an even bigger job creator — renewable energy. Nationally, clean energy jobs outnumber fossil fuel jobs by more than 2.5 to 1, according to a new Sierra Club analysis of Department of Energy jobs data. And when it comes to coal and gas — two sectors President Donald Trump has promised to...

California just put serious limits on methane leaks

The California Air Resources Board voted unanimously on Thursday to enact regulations that will curb the amount of methane the oil and gas industry can leak and vent during production and storage. The new rule — years in the making — requires oil and gas companies to monitor infrastructure and repair leaks. It is a massive step forward for California’s air quality...

Driven by heat and high winds, wildfires are 10 times worse so far this year than average

Wildfire season, or the period between spring and late fall when dry weather, heat, and ignition sources make wildfires more likely, is already off to a devastating start, with fires already burning through a combined 2 million acres across the country — ten times the average for mid-March. Record-high temperatures combined with low humidity and high wind have created...

Trump’s Defense Secretary Cites Climate Change as National Security Challenge

Secretary of Defense James Mattis has asserted that climate change is real, and a threat to American interests abroad and the Pentagon’s assets everywhere, a position that appears at odds with the views of the president who appointed him and many in the administration in which he serves.

The Trump administration really doesn’t want this climate lawsuit to go to trial

The lawsuit, brought by a group of 21 children and young adults against the federal government, alleges that the United States government has violated the plaintiff’s constitutional right to a healthy environment. The lawsuit is based on the old legal doctrine of public trust, which holds that it is the government’s responsibility to preserve certain natural resources...

Spring in the Smokies

Spring has sprung in the Smokies. Daffodils have popped up, trees are budding, and grass is sprouting green but that’s not necessarily a good thing. For a lot of the country spring has arrived about 3 weeks too soon, a growing result of climate change according to a recent study shared by the US Geological Survey. Looking at data spanning the past 112 years, the...

The great Greenland meltdown

From a helicopter clattering over Greenland’s interior on a bright July day, the ice sheet below tells a tale of disintegration. Long, roughly parallel cracks score the surface, formed by water and pressure; impossibly blue lakes of meltwater fill depressions; and veiny networks of azure streams meander west, flowing to the edge of the sheet and eventually out to...

Antarctica’s sea ice just hit the lowest level ever seen

Since it’s summertime there, sea ice cover is poised to drop even further. Sea ice can fluctuate from year to year, but over the past 20 years, Antarctica has lost 61,390 square miles of ice — a Florida-sized chunk. That’s Act I of the unfolding Antarctic drama. In Act II, the continent’s fourth-biggest ice shelf, Larsen C, sheds a Delaware-sized iceberg. It could break...

We are witnessing a historic passing of the baton of global leadership on technology and climate from the United States to China. The new U.S. administration has said it will abandon climate action, gut clean energy funding, and embrace coal and oil — the dirty energy sources of...

Can Grasslands, The Ecosystem Underdog, Play an Underground Role in Climate Solutions?

Globally, grasslands are one of the most converted and least protected ecosystems. The rich soil of Earth’s grasslands plays an important role in feeding the world and because of this much of our grassland has been converted to row-crop agriculture. Loss of grasslands is a big problem for two reasons: The continual conversion of native grassland puts all grassland...

Scientists sound the alarm on impending ‘major extinction event’

In June of 2016, a group of scientists reported that a tiny rodent found only on a single island off the coast of Australia had officially gone extinct — the first mammalian causality, according to the scientists, of man-made climate change. The tiny mammals might have been the first to go extinct due to man-made climate change, but it’s unlikely they’ll be the last. One...

This is what climate change looks like

Two years ago this month, in a well-publicized and much lampooned political stunt, Sen.

The Hermit Who Inadvertently Shaped Climate-Change Science

It was a year into his life alone in Colorado’s Rocky Mountains when Billy Barr began his recordings. It started as a curiosity, a task to busy his mind during the winter.

How the Parks of Tomorrow Will Be Different

When Congress passed the act creating the National Park Service in the summer of 1916, it instructed the agency to leave park scenery and wildlife “unimpaired for the enjoyment of future generations.” The law did not define “unimpaired.” To Stephen Mather, the charismatic borax magnate who served as the first director of the Park Service, it meant simply “undeveloped.”...
