A surprising new study finds that during the past century the frequency of fog along California’s coast has declined by approximately three hours a day. Published in the Proceedings of the National Academy of Sciences the researchers are concerned that this decrease in fog threatens California’s giant redwoods and the unique ecosystem they inhabit. “As…

The President remains committed to advancing his stalled legislative agenda. Addressing the Democratic National Committee in Washington last Saturday, Obama insisted he is not going to let go of his aspirations for America. “I’m not going to walk away from the American people,” he said. “I’m not going to walk away on any challenge.” However,…

Plans to use concentrating solar power plants in the Sahara to generate and export electricity have been on the table for years. Now, it looks as though political will might help move things forward The logic of the idea would seem obvious to a child: the human race needs to wean itself off fossil fuels,…

The U.N. panel of climate experts overstated how much of the Netherlands is below sea level, according to a preliminary report on Saturday, admitting yet another flaw after a row last month over Himalayan glacier melt. A background note by the Intergovernmental Panel on Climate Change (IPCC) said a 2007 report wrongly stated that 55…

An examination of mineral deposits in a coastal cave on the Spanish island of Mallorca shows evidence of rapid rises and declines in sea level as the planet warmed and cooled. Reporting in the journal Science, University of Iowa researchers said that studies of the mineral, calcite — deposited by sea water on the inside…

Gold medals are not handed out for architectural design, but the environmentally friendly speed skating arena built for the Vancouver Olympics is being called a winner by the bladed athletes who will compete there this month. The Richmond Olympic Oval, considered the signature building of the Games, contains salvaged wood damaged by a pine-beetle infestation…

Why are some wells contaminated and some are not? All wells are not equally vulnerable to contamination because of differences in three factors: the general aquifer chemistry, groundwater age, and paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States receive their drinking…

A team of scientists said in a report on Friday that they had found the strongest evidence yet linking a devastating mud volcano in Indonesia to drilling at a gas exploration well by local energy firm PT Lapindo Brantas. Lapindo has denied triggering the disaster through its drilling activities, arguing the mud volcano near Indonesia’s…

Mars is too cold. Venus too hot. Earth is just right in terms of temperature for us to live. How does this all affect climate change? The notion that scientists understand how changes in Earth’s orbit affect climate well enough for estimating long term natural climate trends is challenged in a recent study.

Are warming conditions in the Arctic unprecedented in Earth’s history? It turns out that they are not. The Earth’s climate has gone through warming and cooling times in the past as can be seen in the fossil record that shows tropical species in regions now too cool to support them. These past variations were obviously…
