The transmitter and receivers Energous brings to my office can send power to two devices that require less than 10 watts of power at a distance of up to 15 feet; eventually, Energous says, it will be able to charge more gadgets at a time.
This debate about whether there will be 1 or 2 meters of sea level rise by 2100, however, pales in comparison to the numbers for the long-term outlook. The last time the planet was steadily 2 degrees C warmer than pre-industrial times, some 120,000 years ago, sea levels were 5 to 10 meters higher than today.
New research indicates that climate change has already triggered an unstoppable decay of the West Antarctic Ice Sheet. The projected decay will lead to at least 4 feet of accelerating global sea level rise within the next two-plus centuries, and at least 10 feet of rise in the end. What does the U.S. look like with an ocean that is 10 feet higher? The radically transformed map would lose 28,800 square miles of land, home today to 12.3 million people.
