Climate Change Could Put Tiny Krill at Big Risk

Climate Change Could Put Tiny Krill at Big Risk

They may be small, but krill — tiny, shrimp-like creatures — play a big role in the Antarctic food chain. As climate change warms the Southern Ocean and alters sea ice patterns, though, the area of Antarctic water suitable for krill to hatch and grow could drop precipitously, a new study finds. Most Antarctic krill are found in an area from the … Read More

Scientists Tease Out Climate Change’s Role in Zika Spread

Scientists Tease Out Climate Change’s Role in Zika Spread

Athletes and tourists converging on Brazil this week are crowding into a country where rapid environmental change and natural weather fluctuations nurtured a viral epidemic that has gone global. The Zika virus has exploded throughout South America, up through Mexico and Puerto Rico and into Florida, but the conditions it needed to fester in … Read More

Climate Change’s Fingerprints All Over California Wildfires

Climate Change’s Fingerprints All Over California Wildfires

Reports this week from the front lines of the Sand Fire in Southern California painted the scene as apocalyptic. The drought-fueled blaze was explosive, fast-moving and devastating, burning through 38,000 acres in the Santa Clarita Valley and forcing the evacuation of more than 10,000 homes. If the state’s wildfire season holds true to forecasts… Read More

Climate Pollution Can Complicate Fishes’ Sex Lives

Climate Pollution Can Complicate Fishes’ Sex Lives

The mating rituals of male ocellated wrasses are as intricate as their shimmering scales, and new research showing that carbon dioxide pollution can affect those rituals has some scientists fretting for the future of fish. Elevated levels of carbon dioxide — which dissolves from the atmosphere into oceans, where it changes acidity levels — can … Read More

More Mosquito Days Increasing Zika Risk in U.S.

More Mosquito Days Increasing Zika Risk in U.S.

Hot and humid summer weather across the U.S. brings with it the rise of the mosquito season, and this year the threat of the Zika virus makes that more than a minor nuisance. Mosquito species found in the Lower 48 states are known to transmit this disease, thriving in tropical and subtropical climates. As the climate warms and humidity increases… Read More

North American Forests Not a Climate Change Remedy

North American Forests Not a Climate Change Remedy

North American forests will not fight climate change by absorbing carbon dioxide at levels once hoped for because the trees may not grow big enough, a study said. The new research challenges previous studies that said trees could grow larger due to higher temperatures brought on by global warming, said the authors of the study published in the… Read More

Local Efforts to Save Coral Reefs May Be Futile

Local Efforts to Save Coral Reefs May Be Futile

Scientists agree that coral reefs will continue to be decimated if climate-changing pollution from fossil fuels, farming and deforestation is not addressed. They disagree, however, over whether local efforts to restrict fishing and reduce water pollution will make meaningful differences in a world of fast-rising temperatures.… Read More

Warming Could Mean More Algae Blooms Like Florida’s

Warming Could Mean More Algae Blooms Like Florida’s

Nearly 240 square miles of Lake Okeechobee, the largest freshwater lake in Florida, are covered in a scum of blue-green algae that has also traveled down nearby waterways and out to the coastline. The stinking sludge has impacted local ecosystems and the tourism industry and caused Gov. Rick Scott to declare a state of emergency in the affected… Read More
