Could Nature Be Planning a Sudden 'Surprise Party'?

The Northern Hemisphere briefly emerged from the last ice age some 14,700 years ago with a 22-degree-Fahrenheit spike in just 50 years, then plunged back into icy conditions before abruptly warming again about 11,700 years ago.

Massive “reorganizations” of atmospheric circulation coincided with each temperature spurt, with each reorganization taking just one or two years, according to a new study.

New Honda is powered by hydrogen, not fossil fuels

Honda Motor of Japan has launched the world’s first hydrogen-powered fuel-cell vehicle intended for mass production.

Although it will make just 200 of its FCX Clarity vehicles over the next three years, Honda plans eventually to increase production, especially as hydrogen filling stations become more common.

And even the small initial run represents progress toward a clean-burning technology many have rejected as too exotic and too expensive to gain wide acceptance.

Solutions: New trading funds highlight expanding role of wind in global warming struggle

Two new Exchange Traded Funds, filed within days of each other with the U.S. Securities and Exchange Commission, will focus on companies that provide products and services to the wind-energy industry, such as turbine makers and utilities with wind farms.

Wind energy reduces carbon dioxide emissions and cuts natural gas and water use. Of particular interest to investors, wind power is unaffected by price swings in natural gas, coal and uranium — all of which soared this year.

The new filings reflect the deepening role of wind in the battle against climate change.

Does economists’ change of tune herald turning point on climate change?

The most interesting aspect of the 1,700 prominent signatories urging U.S. politicians to make immediate, deep reductions in greenhouse-gas emissions is that so many of them are economists.

Predictably, the statement by the Union of Concerned Scientists, issued on the eve of U.S. Senate debate on the Lieberman-Warner climate bill, affirms the long-standing scientific evidence for global warming.

But what was unusual, and surprising, was the prominent role of economists as measured by the statement that acting quickly to cut emissions “would be the most cost-effective way to limit climate change.”

UN Deep-Sixes Algae Seeding Scam

Nearly 200 countries agreed on Friday to a moratorium on projects to fight climate change by adding nutrients to the seas to spur growth of carbon-absorbing algae. Opponents argue the little-tested process has unknown risks which could threaten marine life, for instance by making the oceans more acidic.

Clean Coal's Costs Put It On Life Support!

How many windmills could we build for the cost of one clean coal plant?

Coal is abundant and cheap, assuring that it will continue to be used. But the failure to start building, testing, tweaking and perfecting carbon capture and storage means that developing the technology may come too late to make coal compatible with limiting global warming.“It’s a total mess,” said Daniel M. Kammen, director of the Renewable and Appropriate Energy Laboratory at the University of California, Berkeley.

Skeptics' Longest, Strongest Argument Kicks the Bucket

The humble bucket turns out to be at the bottom of a perplexing anomaly in the climate records for the twentieth century.

Land and ocean temperature measurements show a strange cooling of about 0.3 °C in the global mean temperature in 1945. A US–British team of climate scientists has now found a surprisingly simple explanation for the long-standing conundrum. It turns out that the mysterious drop is due to differences in the way that British and US ships' crews measured the sea surface temperature (SST) in the 1940s.

Book cites population growth as key driver of global warming

After virtually abandoning the issue for three decades, the environmental movement got a bold reality check this week from a new book highlighting relentless human population growth as a driving force behind global warming.

This wouldn’t have raised eyebrows in the 1970s, when the modern environmental movement had its genesis and Paul Erlich’s “The Population Bomb” was on just about everybody’s bookshelf.

Since then, however, overpopulation has dropped from the vocabulary of most environmentalists despite a near doubling of the world’s numbers to an estimated 6.8 billion people today.

Costs of ignoring global warming far steeper than taking action

In sharp contrast to denier’s claims that action against global warming will trigger economic catastrophe, a new study has concluded it would actually be cheaper to cut greenhouse-gas emissions than to suffer the consequences of a changing world.

In fact, the report by economists at Tufts University warns, “The longer we wait, the more painful and expensive the consequences will be.”

University research linked to global warming

A Canadian scientist says university research should be added to the list of human activities that contribute to global warming.

Professor Hervé Philippe of University of Montreal has found that his own research produces 44 tons of carbon dioxide a year.

The average American citizen, in contrast, produces 20 tons of carbon dioxide annually.
