Did icy-methane bring on the age of the dinosaur?

Did icy-methane bring on the age of the dinosaur?

Posted Thu, 21 Jul 2011 18:00:00 GMT by Martin Leggett

The mass extinction 200 million years ago, that paved the way for the rise of the dinosaurs, could have been caused by a massive belch of methane, say scientists in a paper just published online on ScienceExpress. Plant remains show that the atmosphere was rapidly filled with carbon, which could have come from CO2-driven warming, releasing the methane stored in the cold sub-sea sediments.

Scientists have plans for high-tech procedures to reduce climate change. As climate change creates increasing impacts on our planetary ecosystem and the pace of carbon reduction makes many people fear that we are moving too slowly to avert a catastrophe, some scientists have promoted GeoEngineering as a way to stave off disaster.

A study carried out by the French Agency for the Environment warns that emailing is just as bad for the environment as flying. At an average size of 1 MB and 220 working days per year, ADEME has calculated sending work related emails generates 13.6 tonnes of CO2, about 13 round-trip flights from Paris to New York.

China was a late-arriver to the green technology craze. But it's making up for lost time - and then some - by taking Western innovation and doing it better. In the process, the world's biggest polluter has become the world's king of greentech.

Windbreaks have several agricultural benefits, but because trees grown in these rigid lines behave differently it's been hard to measure their impact on climate change, until now. American farmers already use windbreaks. They take up a small amount of land, help to protect both crops and livestock from a battering and keep a check on soil erosion too.

A UK university today announced a £400,000 investment to develop automotive technologies which can save fuel and reduce carbon emissions. The move comes from the University of East Anglia, which says money from its Low Carbon Innovation Fund (LCIF) project will support development work already under way from Essex company Controlled Power Technologies (CPT).

A pioneering paper in today's Science has been able to put a number to the temperature-chart of 150 million-year old dinosaurs - using enamel from their teeth. Two larger dinosaurs species have had their temperatures taken, showing a warm 96-100°F - but more work is needed with their smaller cousins to settle the warm-blooded vs cold-blooded debate.

Researchers from the University of Minnesota have created a remarkable new alloy, Ni45Co5Mn40Sn10, that can generate powerful magnetic currents - and so electricity - when warmth flips it from one phase to another. The material is described in a new science journal, Advanced Energy Materials, and the team hopes that its high efficiency will lead to better use of waste heat - and even to the sourcing of green electricity from the oceans.

Researchers at the Plymouth Marine Laboratory and the Marine Biological Association (UK) together with colleagues from the University of North Carolina (USA) have made an important contribution to our understanding of the relationship between marine plankton and ocean pH.

Traditionally, coal has been used for the production of electricity by burning it in power stations to produce steam which then turns turbines and generates power. However, researchers from Brookhaven National Laboratory, Oak Ridge National Laboratory and the New Jersey Institute of Technology have published a paper which may ultimately change that.

The mystery of life between the total ice lock-downs of two Snowball Earth eras - when the planet was covered in ice from pole-to-pole - is being swept away by new research, just published in Earth and Planetary Science Letters. It seems that tiny amoeba were reaching out into the sea, to make some of the first sea-shells from floating particles, right after the first Snowball Earth event ended, some 710 million-years ago.

A new book on the diplomatic triumph of the 'border-less' Antarctic Treaty in 1959, is being launched today, as the 5th Malaysian International Seminar on Antarctica draws to a close. The book's editor, respected polar scientist Paul Berkman, sees the need to re-summon the political will shown back then, so as to deal with the ultimate cross-border threat - global warming.

Thunderstorm predictions during the Sahel monsoon season, in Africa, are likely to be improved by work published in Nature Geoscience today. By using incredibly detailed satellite images, scientists have discovered that soil moisture levels can be a big factor in some of the crop-nourishing storms breaking out at that time of year.

With high oil prices are sailing ships about to make a comeback? In order to lower running costs, cargo ships are now often reducing speed to 12-15 knots, but this makes them slower than the sail-powered clipper ships of a century or more ago.

Oxygen-poor 'dead zones' ebb and flow across the oceans

Oxygen-poor 'dead zones' ebb and flow across the oceans

Worries about the growth of oxygen-depleted dead zones may be eased by a new study, which models the 50-year evolution of low oxygen tongues and plumes across the oceans. The paper in Science shows that bacteria have a big influence on the ebb and flow of oxygen through the seas – but that a long term decline in oxygen, due to global warming, is still likely.

In today's Nature, a scientist is pointing to the role of 'Critical Zone Observatories' in understanding soils and fast-tracking solutions to preserve them - even as greater demands are placed on them. With the roots of civilization holding on tenuously to the denuded resources of the soil, action is needed fast, says Prof. Banwart.
