Three years ago, Kim Cobb was feeling “completely overwhelmed” by the problem of climate change. Cobb spends her days studying climate change as director of the Global Change Program at Georgia Tech in Atlanta, but she felt paralyzed over how to be part of the solution in her personal life. The barriers felt immense. She […] More
A decade ago, climate change projections pointed to a distant future, 50 or 100 years down the road. But with each storm and fire season seemingly more ferocious than the last, it’s clear we’re already facing the impacts of climate change: Sea levels are rising, and storms, wildfires and droughts are intensifying, fueled by warmer […] More
Hurricane Maria roared across Puerto Rico in late September 2017. The storm caused an estimated $90 billion in damage, demolished the power grid (SN: 2/15/20, p. 22) and left more than half of the island’s residents without safe drinking water. Dachiramarie Vila recalls the smell of gasoline from generators choking the air. “The smell was […] More
In the film Planet of the Humans, producer and director Jeff Gibbs and executive producer Michael Moore take aim at renewable energy technologies and the environmental organizations such as 350.org and the Sierra Club that promote them. The film’s premise is that green tech is not so green and that turning to this technology as […] More
Human beings have a superpower — sweating. When temperatures rise, beads of sweat exude from our pores and evaporate, releasing energy that cools the skin and keeps our bodies from overheating. This self-cooling mechanism has helped humans spread to every hot and humid corner of the globe. But that sweating superpower has a theoretical upper […] More
Microbe communities living in the seafloor off Peru haven’t bounced back from a deep-sea mining experiment 26 years ago. The populations are still reduced by 30 percent in this part of the South Pacific Ocean, researchers report April 29 in Science Advances. From 1989 to 1996, the DISturbance and reCOLonization, or DISCOL, experiment plowed grooves […] More
In the tug-of-war between coastal melting and inland ice buildup, the meltdown is winning in both Greenland and Antarctica. Initial observations from NASA’s ICESat-2 satellite in 2018 and 2019 reveal how the Greenland and Antarctic ice sheets have changed since the original ICESat mission collected data from 2003 to 2008. Both missions measured the height […] More
When it rains heavily in Hawaii, lava pours from the volcano Kilauea, according to a new study facing strong scrutiny by some volcanologists. Starting in May 2018, the volcano dramatically ramped up its 35-year-long eruption, opening 24 new fissures and shooting fountains of lava 80 meters into the air. Within three months, the volcano had […] More
