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.
We often hear reports that sea level is rising due to global warming but what is sea level and how is sea level measured? When it is stated that sea level is rising, this usually refers to mean sea level, which is the average sea level around the earth based on numerous measurements over a long period of time. The elevation of mountain peaks are measured as the height of the peak of the mountain above mean sea level.
