When forests are logged, managed or selectively trimmed so they’ll be less susceptible to raging fires, there are usually huge piles of stumps, branches and other wood debris left laying on the ground. Now a group of researchers at the University of Washington in Seattle is developing a portable technology to turn these waste piles into treasure troves by converting them into biochar; charcoal made from plant material that can be burned for energy or applied to soils, where it helps plants grow.

A cap and trade system for carbon dioxide has been a terrific flop; even proponents are leery that it is just another layer of bureaucracy and the only economic benefits have been of the economic voodoo kind, similar to a federal stimulus package that went primarily to state and municipal union employees were called 'jobs saved' in a brilliant bit of marketing.

Why would anyone want to export that fiasco to another environmental issue?  It's academic.  Sometimes academic is obviously a good thing; basic research, for example.  And sometimes 'academic' connotes 'out of touch with reality', like people in the humanities who try and argue that communism really works, it's just that no one has really tried it.

If enough ice from land slides into the sea, the sea level can measurably increase, in the same way that the water in a glass will rise if an ice cube is dropped into it. Because water's molecules are more closely packed in the liquid state than they are in the solid state, they can support ice's open, hexagonal and  less dense structure. When ice is floating, water's buoyant force has the same magnitude as the ice's weight. And the buoyant force is simply equal to the weight of water displaced by floating ice.

How can basically honest scientists using a rigorous methodology have different data?  Numerical models are tricky business and while climate scientists are rapidly becoming experts in statistics and creating better models, that was not always the case.

One vital component of getting clean models is accurate calibration. Calibration is life, in science.  A satellite temperature record put together by the University of Alabama in Huntsville in 1989 has often been cited by climate change skeptics as evidence of doubt that models showing the impact of greenhouse gases on global warming are accurate.

A new paper by Natural Resources Defense Council says hydraulic fracturing (fracking) generates massive amounts of polluted wastewater in in the Marcellus Shale that threatens the health of drinking water supplies, rivers, streams, and groundwater - and that federal and state regulations have not kept pace with the dramatic growth of fracking and must be strengthened to reduce the risks of health issues throughout the Marcellus region.

Over the past century, 70 percent of beaches on the islands of Kaua'i, O'ahu, and Maui have had long-term erosion, according to a U.S. Geological Survey (USGS) and University of Hawai'i (UH) report released today.

They studied more than 150 miles of island coastline (essentially every beach) and found the average rate of coastal change – taking into account beaches that are both eroding and accreting – was 0.4 feet of erosion per year from the early 1900s to 2000s. Of those beaches eroding, the most extreme case was nearly 6 feet per year near Kualoa Point, East O'ahu.

Anthropogenic climate change is so anthropomorphic.  While we think we have a mighty impact on the atmosphere, sauropod dinosaurs millions of years ago shouldn't be left out of the pollution hall of fame - they alone could have produced enough methane to warm the climate many millions of years ago, according to a numerical model.

Like CO2, methane is a greenhouse gas, but with 23X the warming impact of CO2. It's produced by dying plants and cow burps - and cows share one thing in common with hulking sauropods, distinctive for their enormous size and unusually long necks, that were widespread about 150 million years ago. As in cows, methane-producing microbes aided the sauropods' digestion by fermenting their plant food.

The iconic Coelacanth are fish well-known as ‘living fossils’. Coelacanths were thought to have died out with the dinosaurs and then a living one was caught off the coast of South Africa in 1938, sending waves of excitement throughout the scientific world.
