How do hurricanes form? How do we predict their paths? How can we improve predictions? More
Horrific Hurricanes
Atmospheric science
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
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
Texas is dry and hot. Global warming?
Was the epic 2011 heat wave in Texas due to global warming or natural variation? More
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
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?
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!
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
Carbon tax or carbon trading? Can economics battle global warming?
On the virtues of the carbon tax for controlling greenhouse gases… More
Ultimate Storm: What are hurricanes?
How do hurricanes form? How do we predict their paths? How can we improve predictions? 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
Antarctic Ozone Hole Sets New Record
Measurements show a huge ozone hole. How can this happen? We thought ozone-destroying chemicals were being phased out… More
Farming: Does it Change the Climate?
Land use: When it changes, so does the climate! The plow and the thermometer: What relationship? 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
