Thawing permafrost driven by climate change could free decades-old radioactive material, antibiotic-resistant microbes and unknown viruses that have been frozen for millennia.
It's real. It's happening. It's accelerating. And it's our fault. Human activity — particularly the production of greenhouse gasses from fossil fuel emissions — is reshaping our planet, effecting rapid environmental change at a rate never seen before. Global temperature averages are creeping upward, seas are warming, rising and becoming more acidic, and extreme weather events such as droughts, wildfires, floods and powerful storms are more commonplace. Here's where you'll find the latest on the effects of climate change, and the measures that scientists, world leaders and innovators are taking to reduce our harmful impact on the planet and mitigate the damage already done.
The thinning of an icy "glue" that holds fractured ice together may drive ice shelf collapse in Antarctica, according to a new study.
The melting of Earth's polar ice is warping the planet's crust. Here's how that's linked to climate change.
The Southwestern United States is experiencing the worst drought in the region's history, a new NOAA report finds.
A new study shows that strict caps need to be placed on fossil fuel extraction to avoid the worst impacts of climate change.
Hundreds of scientists with a UN panel reviewed more than 14,000 studies documenting climate change evidence, to create a new report for policymakers worldwide.
Although scientists don’t fully understand the varying strengths of the factors contributing to the slowdown, all of them are linked to human-caused climate change.
One estimate suggests that 13 billion tons (12 metric tons) of ice made its way into the ocean on a single day.
A new report signed by 14,000 scientists assesses Earth's 'vital signs,' and finds 'untold suffering' awaits if climate change isn't dealt with soon.
A United Nations panel is preparing to present the first of three reports on climate change, defining the factors that shape it and recommending strategies for policymakers and global leaders.
A high-altitude balloon mission would investigate a controversial way to reduce global temperatures.
A 1972 report predicted the collapse of human society by the mid-2000s. New research suggests that, yeah, we're right on track.
The Amazon rainforest is creating more CO2 emissions than it is absorbing, causing global climate change to accelerate, a new study finds.
The mass death of animals such as mussels and clams will have a significant impact on coastal water quality, scientists say.
Coastal flooding could quadruple in the US in the 2030s, a new study of the lunar cycle and sea level rise finds.
The planet has been losing 33,000 square miles (87,000 square kilometers) of ice coverage each year since 1979.
