Climate change could release unexpectedly huge stores of carbon dioxide from Arctic soils, which would in turn fuel a vicious circle of global warming, a new study warned Sunday.

And according to one commentary on the research, current models of climate change have not taken this extra source of greenhouse gas into account.

Scientists have long known that organic carbon trapped inside a blanket of frozen permafrost covering one fifth of the world’s land mass would, if thawed, release greenhouse gases into the atmosphere.

Parts of the Endangered Species Act, which has protected nature in the United States for 3 1/2 decades, soon may be extinct. The new regulations, which do not require Congress’ approval, would reduce the numbers of mandatory, independent reviews government scientists have been performing for 35 years, according to a draft first obtained and reported by The Associated Press.

As world oil production has never peaked before, there is no historical basis for making informed judgments as to what is going to happen.

All we know is that some six billion people, living in some 200 economies on this earth are soon going to be confronted with getting by on less than the 86 million barrels of oil per day (b/d) that we currently consume. The outcome of the interaction among all those people, all those countries and all that oil is too complex to foresee with any clarity.

About half the world’s apes, monkeys, and other types of primates are in danger of extinction, according to a new study that predicts a bleak future for many of humankind’s closest relatives.

Primates are falling prey to intense hunting and rapidly losing their habitats to deforestation, the study released Monday said.

Like it or not, oil fuels the engines of industrialized economies. In California, we burn through nearly 20 billion gallons of the stuff each year just driving around. Then there’s the oil we use to grow and transport food and pump water, the oil that fuels planes, trains and cargo ships, and the oil that is embedded in every computer, every inch of asphalt and every bit of plastic. So imagine my surprise when I learned that oil supplies are running out - and that the federal government is doing nothing to prepare for it.
