This Startup Wants To Plant One Billion Trees a Year Using Drones

Deforestation downs 10 billion trees around the globe annually. Replanting trees by hand is slow, expensive, and barely puts a dent in reversing the damage. But one startup wants to use drones that can reforest our increasingly tree-strapped Earth, on a big enough scale to replace slow and expensive hired humans. »10/05/15 9:30amMonday 9:30am

Why fighting wildfires makes wildfires even crazier and harder to fight

Here’s an interesting argument from MinuteEarth saying that we should stop fighting wildfires so vigilantly because we’re actually making wildfires even worse and harder to stop. Why?

How Plants and Animals Would Colonise an Ice-Free Antarctica

Antarctica’s ice sheets could totally collapse if the world’s fossil fuels are burnt off, according to a recent climate change simulation. While we are unlikely to see such a dramatic event any time soon, we are already observing big changes and it’s worth considering what the worst case scenario might look like for… »9/16/15 4:00am9/16/15 4:00am

Even Spaceflight Will Be Impacted By Sea Level Rise

Sea level rise isn’t just a problem for coastal cities, it’s a problem for NASA. Two thirds of the space agency’s infrastructure, including the Kennedy Space Center, the Ames Research Center, and the Johnson Space Center stand between 5 and 40 feet (2 to 12 meters) above mean sea level. By the end of the century,… »9/08/15 1:55pm9/08/15 1:55pm
