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.
Unfortunately, even if we curb global warming emissions today, these problems are likely to get worse before they get better. According to marine geophysicist Robin Bell of Columbia Universityâs Earth Institute, sea levels rise by about 1/16â for every 150 cubic miles of ice that melts off one of the poles.WF says that rising sea levels throughout tropical and sub-tropical regions of the world have inundated coastal ecosystems, decimating local plant and wildlife populations. In Bangladesh and Thailand, coastal mangrove forestsâimportant buffers against storms and tidal wavesâare giving way to ocean water.
