Lightning strikes will surge with climate change
Warming temperatures will lead to 50 percent more lightning strikes across the 48 U.S. states in the next century, researchers report. That increase could lead to more warming, more fires and even more deaths.

Thirst for water moves and shakes California
Here’s a scary cost to pumping up groundwater to slake the thirst of crops in California’s Central Valley: It may uplift nearby mountains and trigger tiny earthquakes, experts find.

Teen puts calculus on ice
Jacob Nichols wondered if he could use calculus to find the volume of the icicles building up outside his house. His study earned him a spot at the 2014 Intel International Science and Engineering Fair.

The quake that shook up geology
North America’s biggest earthquake struck 50 years ago. Here’s what science has learned about Earth since the 1964 Great Alaskan Earthquake.

Burning to learn
Fires cause billions of dollars of destruction to homes and forests every year. But not all fires are bad, especially for forests. With a better understanding of fire, scientists can both help people prevent dangerous fires — and identify which ones it would be better to let burn.

Earthquake-triggered lightning?
An experiment with beads offers support for the claim that a rare type of lightning may accompany some quakes.
