This week, world leaders are converging in Paris to talk about climate policy. Under current guidelines, the planet is on target to warm by 2 degrees Celsius in 2050 and by 4 degrees in 2100, triggering serious large-scale problems by the end of the century. “Drought, heat waves, forest fires — we are already seeing this,” says … Read moreThe Climate Change Facts You Need to Know
Scientists have long known that volcanoes cool the atmosphere because of the sulfur dioxide that is expelled during eruptions. Droplets of sulfuric acid that form when the gas combines with oxygen in the upper atmosphere can persist for many months, reflecting sunlight away from Earth and lowering temperatures at the surface and in the lower … Read moreSmall volcanic eruptions explain warming hiatus
As warm ocean water rises up to melt them, glaciers around the Amundsen Sea are losing half a Mount Everest a year. A second study, published Thursday in the journal Science, helps explain the accelerating ice melt: Warm ocean water is melting the floating ice shelves that hold back the glaciers. The two new pieces … Read moreWarming Seas Drive Rapid Acceleration of Melting Antarctic Ice
New research suggests that unlawful marijuana farming is diverting water sources, poisoning animals, and increasing erosion. It began with dying weasels. First one, then many, all mysteriously killed by rat poison banned in the lush Northern California forests where the animals live. Damning evidence soon pointed to a surprising culprit: illegal marijuana farms, where growers … Read moreGreen But Not Green: Pot & The Environment
The cherry blossoms in Washington D.C.’s annual festival now bloom five days earlier than when the festival was celebrated in 1921 (on average). Scientists theorize that with the drastic warming of the globe, future decades could see blossom times not just a few days early but advanced by almost a month. To better understand the … Read moreCould cherry blossoms one day be blooming in winter?
Can a status update from a tulip tell us anything about climate change?
When biologist Tyrone Hayes discovered that a top-selling herbicide messes with sex hormones, its manufacturer went into battle mode.
Researchers at Los Alamos National Laboratories and elsewhere are investigating other aspects of fire propagation, like how big fires create their own weather — a process that has contributed to some of the most devastating fires in recent years. The setup in the photo above is known as a “fire-whirl generator” and is used to … Read moreInto the Wildfire

Octavio Aburto, a Scripps Oceanography research scientist, traveled to a marine reserve in Mexico and took this stunning photo of bigeye jacks swirling like a tornado in front of David Castro, a local naturalist. (And in case you think it’s photoshopped, here’s the behind the scenes video.)
