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

This Is What the Ice-Free Northwest Passage Looks Like

This Is What the Ice-Free Northwest Passage Looks Like

An ice-free Northwest Passage was once the stuff of legend. But it’s now becoming the norm thanks to global warming, and commercial freighters to luxury cruise ships are racing to turn a profit off the newest frontier on earth.

2015 Set Frenzy of Climate Records

2015 Set Frenzy of Climate Records

The warming of the world’s climate has reached a fever pitch in recent years, causing records to fall like dominoes. In 2015, the planet saw a number of such records set, from the hottest global temperature measured to the largest annual increase in carbon dioxide. Those records — along with numerous other indicators of the considerable change… 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

Diving Enthusiasts Could Measure Ocean Temperatures

Diving Enthusiasts Could Measure Ocean Temperatures

Millions of holidaying scuba divers are able to become citizen scientists and take vital measurements of ocean temperatures, which are being driven up by climate change. More than 90 percent of the heat trapped by global warming goes into oceans, where it drives hurricanes and disrupts fish stocks. Satellites can measure surface temperature when … Read More
