The Next March Is All About Climate Change

The Next March Is All About Climate Change

For the second weekend in a row, Washington, D.C. will be home to people clamoring for policies based on science. But unlike the March for Science, this weekend’s People’s Climate March will be overtly political and put a sharp focus on climate change and justice. The march builds on a 2014 landmark event that drew hundreds of thousands to the … Read More

California Got More Snow This Winter Than Past 4 Total

California Got More Snow This Winter Than Past 4 Total

That it was wet this winter in California is an understatement. After four years of drought, the Golden State faced a whiteout of epic proportions. Mountains were caked in nearly 800 inches of snow and ski resorts are slated to stay open into summer to take advantage of snowpack unseen in years. Reservoirs filled, dams overtopped with nearly … Read More

Climate Change Altering the Arctic Faster Than Expected

Climate Change Altering the Arctic Faster Than Expected

Evidence continues to mount that climate change has pushed the Arctic into a new state. Skyrocketing temperatures are altering the essence of the region, melting ice on land and sea, driving more intense wildfires, altering ocean circulation and dissolving permafrost. A new report chronicles all these changes and warns that even if the world … Read More

Climate Change Was the Epicenter of March for Science

Climate Change Was the Epicenter of March for Science

The roar of the crowd of thousands of scientists and supporters rippled up and down Constitution Avenue like a wave on Saturday. It found two fitting sounding boards on either side of the street. On one side, the Smithsonian, the world’s largest museum and research program. It’s a literal institution in the science community, with its research cut … Read More

The Energy Dept. Website Shifts Focus to the Economy

The Energy Dept. Website Shifts Focus to the Economy

The Trump administration is cutting down on greenhouse gases . . . on its websites, that is. The Department of Energy’s pages on bioenergy and wind energy as well as transportation have both reduced their mentions of greenhouse gas emissions and reducing fossil fuel use in favor of language more geared toward jobs and energy independence. They’re … Read More

This App Shows What Sea Level Rise Will Do

This App Shows What Sea Level Rise Will Do

The oceans are rising and already creating problems from Boston to Miami. But the true scope of what the world is in for is hard to imagine. Standing on dry land today and knowing that it will be underwater by 2100 is understandable in some abstract way, but abstractions don’t exactly move people to undertake action, let alone at the scale needed … Read More

We Just Breached the 410 Parts Per Million Threshold

We Just Breached the 410 Parts Per Million Threshold

The world just passed another round-numbered climate milestone. Scientists predicted it would happen this year and lo and behold, it has. On Tuesday, the Mauna Loa Observatory recorded its first-ever carbon dioxide reading in excess of 410 parts per million (it was 410.28 ppm in case you want the full deal). Carbon dioxide hasn’t reached that … Read More

The March For Science is Heading to Greenland

The March For Science is Heading to Greenland

Field research season is getting underway in Greenland. Scientists are racing to the island for the few months a year when the towering ice sheet is accessible. Despite the scramble to get as much research done as possible in such a tiny window, scientists will take a moment on Saturday to march in solidarity with thousands of other researchers… Read More

This Graphic Puts Global Warming in Full Perspective

This Graphic Puts Global Warming in Full Perspective

To say the world is having a streak like no other is an understatement. Global warming has made cold scarce on a planetary scale. This March clocked in as the second warmest March on record when compared to the 20th century average, according to newly released data from the National Oceanic and Atmospheric Administration. NASA data published last … Read More

Harvard Scientists Taking Geoengineering Into the Field

Harvard Scientists Taking Geoengineering Into the Field

Geoengineering has been a topic on the fringe of climate discussions for more than a decade, but it’s been edging ever closer to the mainstream as carbon pollution rises. It’s slated to take a step closer still later this year, with a group of Harvard scientists planning a small scale experiment. Their test will redirect the sun’s rays back into s… Read More

New Posters Imagine National Parks in 2050; It’s Not Pretty

National parks are at the front lines of climate change. The creep of change is playing out in places that Americans have set aside to be preserved for the enjoyment of future generations. A new poster series takes the landscapes that have inspired countless road trips and daydreams of summer vacation and imagines what they’ll look like in 2050 if… Read More

NOAA Is Still Lacking an Administrator to Lead Agency

We’re 12 weeks into the Trump administration and there’s a glut of nominations President Trump has yet to put forward. Many are crucial to having a functioning government and setting the priorities for their agencies. In the climate world, there’s perhaps no more important position to fill than the head of the National Oceanic and Atmospheric … Read More

Hey Look, Another Record Low Month for Sea Ice

Hey Look, Another Record Low Month for Sea Ice

Climate change continues its rapid reshaping of the Arctic as yet another month saw sea ice set a record-low mark. March data just released by the National Snow and Ice Data Center marks six months in a row of record-low sea ice for the region. It’s a story that’s been reported so often recently, it risks feeling almost normal. But make no mistake… Read More

The March for Science is Getting Organized

In a little over two weeks, scientists and science advocates are planning to flood the streets of 480 cities around the globe. They’ll stand up for science, but March for Science organizers want to make sure they don’t go back to sitting down after that. On Monday, the organizers revealed they plan to keep organizing for science after the April 22… Read More

Scientists Just Confirmed the Great Barrier Reef Bleached

Climate change is putting one of the wonders of the world in a vice. For an unprecedented second year in a row, Great Barrier Reef coral have been decimated by a wave of warm water. Last year’s mass bleaching was fueled in part by a powerful El Niño, but would have been nearly impossible without climate change bumping up background temperatures … Read More

Energy Dept. Scrubs Paris Agreement From Climate Page

The expunging of climate information from government websites under President Trump continues to march forward with the latest changes happening to the Energy Department. The agency’s climate change page once prominently featured a video about the Paris Agreement along with extra links to climate information. Now it’s a little more barren. While … Read More

Icebergs Are Swarming Shipping Lanes in the Arctic

Icebergs Are Swarming Shipping Lanes in the Arctic

Like bees, icebergs sometimes roam in swarms. Unlike bees, icebergs can sink ships. It’s with that threat in mind that shipping companies are now avoiding parts of the North Atlantic, where an unusually large swarm of icebergs is making life miserable for captains on the high seas. Around 450 icebergs — defined as hunks of ice covering at least … Read More

Trump’s Executive Order is Out of Step With Americans

President Trump is expected to start the rollback of a wide swath of Obama-era climate regulations when he signs a new executive order on Tuesday. On the chopping block are the Clean Power Plan, methane and coal regulations, and accounting for the social cost of climate change in federal projects. Tuesday’s executive order is part of what Trump … Read More

Climate Change is on Pace to Kill an Ice Age Remnant

Climate Change is on Pace to Kill an Ice Age Remnant

Humans are in the process of changing the planet in a way that hasn’t happened in more than 2.5 million years. For eons, the Laurentide Ice Sheet has been a fixture of North America. At its peak, it covered the majority of Canada and sent icy tendrils down across the Midwest and Northeast, covering Chicago, New York and Toronto in a mile or more … Read More
