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.
This high-tech approach eliminates the problems of land motion on Earth and has given us a new global sea-level rise rate over the past 22 years of 3.2 millimeters per year, the equivalent of 12 inches per century. Wind and currents can affect a seaâs level.
