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.
Hence the relatively small projected sea level rise by the year 2100, as compared to the changes measured in tens of meters that occurred in Earth's history (see Introduction). The rise by 2100 is only a small beginning of a much larger, multi-century response of ocean and ice sheets to elevated global temperatures.
