Was the epic 2011 heat wave in Texas due to global warming or natural variation?

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

Are extreme heat, wicked cyclones and record rainfalls signs of climate change, or just more changes in the weather? Will warming eliminate record cold days? Will hurricanes get bigger?

Pythons, anacondas and boas are breeding in South Florida. What are these snakes eating, besides alligators? Can they be trapped, hunted, poisoned?

Climate scientists worry about feedbacks, glacial melting, sea level rise, and the complexity of climate science. What does human behavior tell us about warming?

Lasers read and write CDs and DVDs, form the heart of fiber-optics, and are being used in climate prediction, chemical identification, high-tech manufacturing, even the battle against influenza.

Greenland’s icecap holds enough water to raise sea level by 7 meters. Some studies show it sliding faster into the sea. Should we worry? New report says “We don’t know.” Comforting?

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?

To understand and protect the home planet: it’s no longer a key NASA mission. What will we lose as NASA turns its eyes toward the moon and Mars?

Global warming is changing the planet: Antarctica is melting, sea level is rising, oceans are turning sour. Killing Amazon forests spreads malaria, reduces rainfall. How sick is our Earth?

A new year is a chance to bring sanity to our medical, scientific and environmental disasters. Here’s our wish-list for a better New Year!

Land use: When it changes, so does the climate! The plow and the thermometer: What relationship?

How do current conditions compare to past predictions of the effects of global warming? Are living on a warming planet?

New evidence from records of lake ice freezing and thawing is evidence for global warming.

Causes and effects of overfishing. Why do fishing regulations fail? Where have they succeeded? Like sushi? Read on: the fish are disappearing fast!
