Heatwaves, hurricanes and other extreme weather might be the "face of climate change," but it's not the only sign. A grim new visualization from NASA shows another problem caused indirectly by global warming: airborne particles and droplets.

The WFP warns progress in reducing global hunger is under threat by conflict and the increase in climate disasters. For the first time in several decades, the WFP reports the number of people suffering from chronic food shortages has risen. ... Read more about WFP: Climate Change to Accelerate World Hunger

Two years after a long-lasting undersea heat wave scalded large sections of the Great Barrier Reef, scientists have found that because so many corals died, much of the reef has probably been altered “forever.”

“What we just experienced is one hell of a natural selection event,” said Terry Hughes, director of the Australian Research Council Center of Excellence for Coral Reef Studies at James Cook University in Queensland. ...
