Time to re-write one little section in my Webster's Dictionary. That's an old-time thing, ink on paper, you remember? It gives the fifth definition of "glacial" as "as slow as the movement of a glacier." Need to change that to read "fast" in the future.

British researchers have found the movement of Antarctic's glaciers is speeding up. During the decade ending in 2003, these southern glaciers speed up by 12 percent. That means these huge rivers of ice are speeding toward the ocean. There three things can happen: the ice melts, … Read more

We're not going to be the first generation of humans to cope with severe climate change. We may simply be the first to know just what's happening.

An international research team traced the growth of farming in Mexico's Iguala Valley. Their new report charts the rise of agriculture as the climate became warmer and wetter. Farming began after the last Ice Age. New lakes formed. Corn and squash were being regularly farmed 8,000 years ago. Then farming spread. Agricultural burning was used. Sixty-three hundred years ago domestic crops were plentiful. Forest clearing increased.

Then, around 1,… Read more

U.S. House of Representatives Speaker Nancy Pelosi (D-Calif.) on Friday called for Congress to enact mandatory restrictions on carbon dioxide emissions by year's end.

At a news conference in Washington D.C. alongside Rep. Edward Markey (D-Mass.), the chairman of the Select Committee on Energy Independence and Global Warming, Pelosi said that as part of a "Fourth of July energy independence package" of legislation, she said it is "absolutely essential" for the House to pass a European-style "cap-and-trade" proposal related to carbon dioxide. The compound, a greenhouse gas released into the atmosphere … Read more

A new scientific study funded by NASA shows that there will be even more rain and snowfall due to global warming. This latest data indicates that rain could increase as much as 13 percent over the next century. The recent Intergovernmental Panel on Climate Change predicted a maximum rainfall increase of 8 percent. So this new satellite-based data may lead to rejiggering currently used climate change models.

The whole report is now available online. You have to pay, or be a member of the American Association for the Advancement of Science (AAAS) to access the complete PDF.

Beginning in 1991, every summer NASA has measured the ice sheets of Greenland. Past data indicates significant thinning of ice along the coast. Meanwhile some ice sheets have thickened in Greenland's interior. Overall, there's much less ice on Greenland's surface than there was 100 years ago.

This summer's NASA expedition to Greenland has returned with fresh data. Now the analysis begins. One piece of equipment used is an ice-penetrating radar that can find bedrock up to 2 miles below the ice surface. NASA estimates an average drop of 9 inches in the height of Greenland's … Read more

Nashville is hundreds of miles from the nearest forest fires. Recently smoke levels there were 20 times normal. Health officials in the southeastern U.S. can now look at maps showing where the smoke is, and where it's going.

This smoke forecasting is being done by the Center for Forest Disturbance Science in Athens, Ga. Both hourly forecast updates and daily peak values of smoke concentrations are available on the Internet.

The 6-week-old fires have burned a half-million acres. And they're still outta control. These fires are a record for Georgia. That's sparked debate over lack of … Read more

The 21st century is already setting records. Wall Street stock prices keep rising, and so does the amount of carbon dioxide we're putting into Earth's atmosphere. It's apparently going to get more uncomfortable for those folks clinging to the theory that global warming is a hoax.

Data released Monday by the Carnegie Institution shows we are now producing near three times as much carbon dioxide as we were during the 1990s.

The global carbon emission study was done by the Carnegie scientists using readily available data from public sources. One source was the Department of Energy's … Read more

You may have missed this on your favorite blog site, and you definitely missed this if you looked at American TV news. Reunion Island got smashed on Saturday. Big waves. Lots of damage. It was not a tsunami this time. Certainly earthquakes can pack an enormous wallop, but the supporters of wind power surely have something going as well.

The European Space Agency (ESA) satellites were tracking the course of the big swells. Ocean swells, not rich guys with big heads. Big, really big waves. Some that slammed into Reunion without warning were over 35 feet high.

First, the satellite … Read more

Carbon dioxide is known to be one of the greenhouse gases that can cause the Earth's atmosphere to retain heat. Today, two new scientific studies have been released that offer more insight into carbon and its dispersal into the air as carbon dioxide.

First, from Australia's CSIRO, the national science agency, comes a study on carbon contained within tropical forests that is thus not available to be released as CO2. This study says the current deforestation rate in the tropics releases 1.5 billion tons of carbon into the atmosphere annually--about one-fifth of all carbon emissions caused … Read more
