Sunburned in Siberia: Heat Wave Leads to Wildfires

A heat wave in Siberia has led to a surge in wildfires, releasing large amounts of greenhouse gases into the atmosphere.… Read More

Melting Permafrost Will Boost Temps, But Not Quickly

Melting Permafrost Will Boost Temps, But Not Quickly

Climate scientists have long known that human-generated greenhouse emissions are only part of the story with global warming. A rising planetary temperature sets in motion all sorts of secondary effects that can boost the temperature even higher — effects like melting Arctic sea ice, rising levels of heat-trapping water vapor in the atmosphere, and … Read More

Image of the Day: Otters Are Climate-Saving Creatures

After studying 40 years worth of data, researchers from the University of California Santa Cruz have found that sea otters play an active role in combating climate change. And it's all thanks to their love of sea urchin, a natural predator of the carbon-sucking coastal seaweed, kelp. In the absence of otters, urchins dine like kings, but in their … Read More

Image of the Day: For This Forest, It’s Easy Being Green

The Iwokrama forest in Guyana is protected by the Conservation Trust Fund, which provides funds for managing the country’s intact protected tropical rainforests that are mostly untouched by humans. This is the first of its kind in Guyana. Having an ecosystem untouched by humans and industrial progress is a good thing for the climate. Deforestation … Read More

NASA Animation: Watching the Earth Breathe

When Charles Keeling first began measuring the atmosphere’s carbon dioxide levels in the late 1950’s, he noted first that they stood at about 315 parts per million (ppm), or 315 molecules of carbon dioxide for every million molecules of air. Soon after, though, he found that the concentrations were rising, thanks to the burning of fossil fuels … Read More

Image of the Day: ‘Supertrees’ Super Useful in Singapore

Trees clean the air. They take in carbon dioxide, a climate inducing greenhouse gas. They provide shade and thus keep forested areas cooler. They purify water. Giant man-made “supertrees¬Ě in Singapore will now provide electricity. The 18 fake trees, some almost 165 feet tall, which were opened to visitors on June 29, make up a project from … Read More

Charcoal decorates the back of a laborer at an illegal charcoal camp nestled in the Brazilian rainforest. Much of the illegally logged trees from the Amazon end up in charcoal camps like this one. The charcoal then travels to the furnaces of smelters that produce pig iron, which is later turned into steel… Read More

The Issue of Population is More Than a Little Radioactive

The Issue of Population is More Than a Little Radioactive

But if you think about it, the Earth’s booming human population is at the root of just about every environmental crisis that threatens the natural world. Last October 31, Earth’s population reached 7 billion people (unofficially, because there’s no way to pinpoint the actual day, but it was in the ballpark). Every last one of them taps into the pla… Read More
