Confusion over how much CO2 can be emitted could undermine global climate action

The potential for drought and large wildfires looms over the summer

Young, thin sea ice melts faster, putting Arctic ecosystems in danger

U.S. has biggest footprint, both from foreign visitors and Americans traveling abroad

Rates have tripled in 15 years, and some scientists suspect climate change is partly to blame

Meltwater is fueling a feedback loop that lets warm seawater eat away at them from below

At least 30 percent of corals died off in 2016, and more extreme heat is likely in store

Warm ocean waters are eating away at ice, but what’s driving that process is unclear

Spikes in sea temperatures stress marine ecosystems, particularly coral reefs

Linked to a warming ocean, ice retreat was more rapid than even at the end of the last Ice Age

And the melt of the massive ice sheet is only picking up speed

Warming rivals habitat loss and land degradation as a threat to global wildlife

Using wood as fuel source could actually increase CO2 emissions

Evidence builds for controversial idea linking Arctic temperature spikes to changing weather patterns

Plantations would have to be massive in scale, and their value is still unproven

But suitable islands for breeding may be harder to find

New data show that ocean acidification not only stops corals from building, it tears them down

Although the Gulf and East coasts get most of the attention, the West Coast could see massive losses

And the longer it takes to reduce carbon emissions, the higher they will go

And if countries do not meet the Paris climate agreement goals, the risks will be even greater

The effect of removing fossil fuel subsidies would fall far short of the reductions promised in the Paris Agreement 

Due to climate change, they already may not be catching enough prey to meet their high energy demands

Over planetary history, warm-blood animals have outperformed cold-blooded animals in adapting to changing temperatures

Ultra-fine aerosol particles, produced by industrial activity, are helping storms grow bigger and more intense in the Amazon basin
