History Shows Weather Patterns May Head North

History Shows Weather Patterns May Head North

As the world warms, weather patterns will change. The already arid Middle East and American West will get even drier, and so will the well-watered Amazon region. Monsoon Asia and equatorial Africa, wet already, will get even rainier, according to new research from Columbia University in the U.S. The oceanographer Wallace Broecker and his colleague… Read More

Tiny Plankton in the Oceans Could Have Big Impact

Tiny Plankton in the Oceans Could Have Big Impact

Some of the most minute forms of marine life may have a significant effect both on more developed creatures and on the oceans’ ability to absorb carbon dioxide. An international team of scientists has found that the smallest species of plankton thrive when levels of CO2, the main greenhouse gas from human sources, rise and increase the acidity of … Read More

Winds of Change: Why Antarctic Sea Ice Is Growing

Winds of Change: Why Antarctic Sea Ice Is Growing

The ice that covers the Arctic Ocean has been on an overall downward trend in summer for more than three decades now, but the growth of sea ice in winter at the opposite end of the world has been trending upward over the same time span. That doesn’t contradict the idea of global warming — for one thing, the growth is very slow compared with ice los… Read More

Worsening Water Scarcity to Affect 2 Billion Globally

Worsening Water Scarcity to Affect 2 Billion Globally

Water scarcity is a fact of life in many parts of the world, particularly in the countries of sub-Saharan Africa. A new study says the situation could get a lot worse, with climate change resulting in less rain and more evaporation in many areas. The study, led by researchers at the Potsdam Institute for Climate Impact and Research and appearing i… Read More

Epic Flooding Deals Colorado Drought Crippling Blow

Epic Flooding Deals Colorado Drought Crippling Blow

All it took was a 1,000-year flood to knock out — or at least significantly dampen — the drought that has been ravaging much of Colorado for at least a year and half. The Sept. 17 U.S. Drought Monitor, released Thursday, shows that nearly all of north-central Colorado is drought free, and the drought is greatly reduced in much of the rest of the … Read More

Microgrids: Sandy Forced Cities to Rethink Power Supply

Microgrids: Sandy Forced Cities to Rethink Power Supply

Hurricane Sandy and the havoc it wreaked on New York City and the rest of the Northeast in 2012 could prove to be a turning point in how people think about the way electricity is produced and distributed in storm-prone areas.… Read More

Newfangled ‘Icepod’ Tracks Greenland’s Melting Ice Sheets

Newfangled ‘Icepod’ Tracks Greenland’s Melting Ice Sheets

The LC-130 Hercules flew low over the ice sheet in a tight grid pattern, Teflon-coated landing skis barely 300 meters above the soft upper layer of snow. At the rear of the plane, scientists clustered round a monitor displaying a regular pattern of dark red waves generated by a radar signal. Somewhere in the vast, white emptiness below were two tin… Read More
