Is It Safe To Eat Snow?

Quick! Something white, cold, and flaky is falling from the sky. Should you start eating it, perhaps by the spoonful? Maybe — but, more likely, maybe not.


The LA Gas Leak Was So Bad You Could See It From Space

The natural gas leak at Aliso Canyon earlier this year was already one of the worst environmental disasters in US history. Several months later, however, it has now gained the additional distinction of being the first industrial methane point-source visible from outer space.


After 60 Years Of Fighting, We Finally Found The Tallest Peak In The US Arctic

A debate over the tallest peak in the Alaskan arctic has finally been settled after almost six decades of fighting. Both Mount Chamberlin and Mount Isto claimed the title as their own. Now, one has emerged triumphant — and a third, entirely separate mountain peak has also entered the scene.


This Pink Snow Does Not Bode Well For Our Future

Your first thought on seeing this weird pink snow might be an industrial accident or a nearby Big Foot massacre. Rest assured, it’s neither — just a perfectly natural, snow-dwelling algae. So why are scientists all in a tizzy about it? Because it’s causing glaciers to melt faster.


Take An Underwater Tour Of The Most Biodiverse Reef On Earth

Coral reefs have been having a rough time of it lately, have you heard? They’re in the midst of the largest, longest and worst mass die-off in history. But there’s a bright spot: When humans take action to protect reefs, they tend to do better. Sometimes, they even thrive.


The Worst Coral Die-Off In History Just Got Worse

The National Oceanic Atmospheric Administration has just released an update on the state of the Earth’s coral reefs, and it’s bleak as hell. For the third year in a row, many reefs around the world will be exposed to hotter-than-normal temperatures, placing them at risk (again) for catastrophic die-offs.


The Last Spot On Earth Just Passed A Historic Climate Milestone

On May 23, something extraordinary happened at the South Pole. For the first time in four million years, carbon dioxide concentrations cleared 400 parts per million (ppm). It’s the last climate-monitoring spot on Earth to pass the historic milestone.


The Most Hopeful Place On Earth For Climate Change

Eastern Canada’s black spruce forests are one of the largest untamed wilderness areas on Earth. And in refreshingly optimistic news, parts of this ecosystem are expected to flourish in a warmer world, creating a refuge for species escaping drought-stricken regions to the south and west.


El Niño Has Pushed Our Planet Past A Major Climate Milestone

The monster El Niño of 2015-2016 is finally gone, but scientists are still coming to terms with its impacts on the planet. Among those impacts: Charging up the global carbon cycle and pushing atmospheric CO2 levels above 400 parts per million (ppm) for an entire year — a first in human history.


Researchers' Attempt To Find Even One Pristine Spot On Earth Ends In Total Failure

An exhaustive attempt by researchers to find a single untouched space on planet Earth has yielded no results. Sorry, folks, everything is ruined now.
