Greenhouse gas maps

Greenhouse gas maps

Using at least 20 sources of data, scientists have modeled releases of carbon dioxide from Indianapolis. The new view will help cities map reductions in greenhouse warming, and help people understand that the climate warming problem belongs to everybody. More »

Ocean fish in hot water

Ocean fish in hot water

The ocean’s most valuable fish are caught in a vise. Areas known as dead zones are encroaching on their living zones and pinning them closer to the surface, where they are more vulnerable to becoming the day’s catch. The predicament is yet another side effect of climate change. More »

Weather, climate, war

Weather, climate, war

If conflicts are more common near the equator, what will global warming affect do? A new study shows increases in conflict during el Niño periods — but only during the warm, dry part of the cycle, and only in places affected by these big climatic cycles. More »

Tornado prediction

Tornado prediction

Tornadoes need wet air, dry air, and wind shear. What explains the big improvement in tornado prediction? Is climate change boosting these storms? More »

Climate: Simple = beautiful?

Climate: Simple = beautiful?

Earth’s orbit subtly changes over thousands of years, in complex cycles that affect the timing and delivery of sunlight to various regions of the globe. Climatologists have said that when this “Milankovitch cycle” warms the Arctic, it somehow warms the Antarctic. A new study finds that the cycle acts more directly. More »

No joke: Laughing gas attacks ozone!

No joke: Laughing gas attacks ozone!

The ozone layer protects Earth from UV rays: Twenty-two years after a treaty to protect ozone, how is the layer doing? What has happened to the ozone hole above Antarctica? More »

Winter’s Weird Weather: Blame el Nino?

Some call it Fall. Some call it spring. But nobody in the Midwest, East Coast or Northern Europe is calling it “winter.” What’s up with our weather? More »

Your Air: Breathe with Care

Farms release airborne, drug-resistant bacteria, and indoor air could be making you sick. More news about the particles we breathe every day. More »

Climate Change: It Can Happen Fast!

Evidence from ice cores in Greenland and Antarctica show how fast the climate has changed in the past. In this era of global warming, you can’t count on a slow, gradual, predictable warming. More »
