He is using his retirement to evangelize for the planet-saving advantages of hydrogen batteries. In December, the California Fuel Cell Partnership tallied 8,890 electric cars and 48 electric buses running on hydrogen batteries, which are refillable in minutes at any of 42 stations there. On the East Coast, ...there’s just one. His name is Mike Strizki. He is so devoted to hydrogen fuel-cell energy that he drives a Toyota Mirai even though it requires him to refine hydrogen fuel in his yard himself. ...You can make fuel using water and solar power, .... The byproduct of making hydrogen is oxygen, and the byproduct of burning it is water. Hydrogen is among the most plentiful elements on earth, so you don’t have to go to adversarial countries or engage in environmentally destructive ext...

The hole, scientists believe, ultimately penetrates more than a half-kilometer into the ice, joining a network of channels extending all the way to the base of the ice sheet. ...Covington and his colleague Jason Gulley, ...were motivated by a scientific question with enormous implications as the climate warms. Just how vast are these moulins, these ice caves found by the thousands across Greenland’s surface? How much are they undermining the integrity of the second-largest sheet of ice on the planet? And how much worse will it get as melting, and moulins, begin to extend farther and farther toward the airy center of Greenland, where the ice is well over a mile thick? ...As the climate warms — with the Arctic warming fastest of al...

The debate now centers on just how bad things will get. But there are still major uncertainties when it comes to modeling future climate. Chief among them: How much more carbon dioxide will humans emit, and how sensitive is the climate system to all those emissions anyway?...To account for those uncertainties, the United Nations Intergovernmental Panel on Climate Change (IPCC) created several baseline scenarios, known as Representative Concentration Pathways (RCPs), to describe just how much warming might result from a range of carbon emissions. ...The most extreme model,  RCP 8.5...

The need to study the real-world effects of releasing reflective particles is pressing, says David Keith, a Harvard energy and climate scientist and one of SCoPEx’s lead scientists.
