Sea cow teeth point to a wetter Eocene and a 'greenhouse earth'

Sea cow teeth point to a wetter Eocene and a 'greenhouse earth'

Posted Thu, 21 Apr 2011 18:02:01 GMT by Martin Leggett

Sea cow teeth from 50 million years ago are helping scientists to flesh out the climate of the earth during the Eocene, a time when greenhouse conditions reined supreme. Their paper, published today in Science, confirms that very wet conditions extended right down to the tropics, where rainfall rates were much greater than that seen today.

Ozone hole's long reach brings climate change to the tropics

The ozone hole over Antarctica could be causing the tropics to have wetter summers, increasing flooding and landslide risks, according to recent research published today in Science. A team from Columbia University has found that the ozone hole is helping to shift the jet streams south, making parts of the tropics much rainier than they were before. The results imply it is not just greenhouse gases that can change the climate.

Rapid increase in ice loss from the Canadian Arctic

The vast Canadian archipelago of Arctic islands, the territory of Nunavut, covers an area the size of western Europe. New research shows that the melting ice caps and glaciers there play a much greater role in global sea level rise than previously believed - 1mm in only 6 years.

A quarter of the Arctic's permafrost coastline is suffering from erosion due to climate change. The impact on settlements, shipping, oil and gas installations and coastal infrastructure is likely to grow. As ice free periods increase due to global warming, there is a direct effect on the fragile polar coastline which is largely composed of frozen permafrost.

Sugarcane in Brazil's cerrado can have a cooling double whammy. It helps to power private transport, with cane ethanol that has fewer greenhouse gas emissions - and now it has been shown to potentially help cool the local climes too. A paper to be published in Nature Climate Change, has measured the effects of switching from other crops and cattle to sugarcane - and the dense thickets of cane are better at reflecting sunlight, and cooling through water loss.

Damaged coastal wetlands means bad news for our climate

A new World Bank report has found that drainage and degradation of coastal wetlands leads to decreased carbon sequestration and increased amounts of carbon dioxide in the atmosphere. If coastal wetlands are drained, for example to convert the land for agricultural use, they emit large amounts of CO2 into the atmosphere

The study of fossilised mollusks could give scientists an invaluable insight into the way the world will respond to climate change. Researchers at Californian university UCLA say that examining the fossils from 3.5 million years ago has allowed them to build a picture of how the world is reacting to current levels of atmospheric carbon dioxide, a key contributor to global climate change.

West Antarctica gets warmed from tropics via 'Rossby waves'

West Antarctica gets warmed from tropics via 'Rossby waves'

Posted Mon, 11 Apr 2011 15:11:02 GMT by Martin Leggett

A long train of low-and-high pressure areas, known as Rossby waves, are helping to channel increasing warmth in the equatorial Pacific over to the Antarctic - according to research in Nature Geoscience. That is also producing an increase in warming in Western Antarctica, which contains vast amounts of water locked in its thick ice-caps. Melting here could pump 15 feet of sea-level rise out across the globe.

Despite containing half the world's population, and being particularly vulnerable to climate change, most cities are failing to prepare themselves for the anticipated risks. That's the conclusion of a report in this month's Current Opinion in Environmental Sustainability. The author concludes that a short-term pressures are swamping the long-term planning needed to safeguard cities from events such as tidal-flood surges or heat-waves.

Australian researchers discover the world is getting windier and waves higher. Using five techniques to independently measure the figures, they found the speeds of the fastest winds have increased by around half a percent. The height of the biggest waves has risen by between a quarter and half a percent.

Leaf rot slows after droughts, hindering plant growth

With hotter, driers summers, tree leaves don't only shrivel - they produce more tannins, which changes the way that they rot over the autumn. New research published in New Phytologist suggests this subdues plant growth in the drought's aftermath, so extending the knock-back from dry-period. It also causes subtle inter-plays in the carbon cycle, which have yet to be teased apart.

Unusual atmospheric conditions during the last Arctic winter have opened a massive hole in the ozone layer and that hole is extending into the more densely populated latitudes of northern Europe. Ozone depleted air masses are moving south from the Arctic and have reached Finland. They are expected to move as far east as the Russian-Chinese border and perhaps as far south as the Mediterranean.

Patagonia glaciers now melting ten times faster

A new study, published in the current issue of Nature Geoscience, has been able to measure the rate of Patagonia glacier loss over the last several hundred years. The team of scientists, from Britain and Sweden, has found that current melting rates are ten times faster than newly measured historical rates. With temperatures in the region rising fast, in line with global warming climate model projections, it seems the death of Patagonia's glaciers has man's hand behind it.

Scientists from Leeds and Aberystwyth University recently discovered that rocks displaced by the Antarctic Ice Sheet are found on James Ross Island, indicating that the sheet must have expanded this far earlier.

The FAO has warned of the ''potentially catastrophic'' future impact on food production in the developing world by 'slow-onset' climate change. But doour governments presently take too much of a short-term approach to such changes? Andhow can we prepare for them to make developing world food production more resilient whilst managing the trade-offs?

Carbon labelling will help consumers more accurately reflect their green intention says new research and producers will cut energy use and boost their environmental credentials too. Thomas Dietz, a sociology professor from Michigan State University, publishes his research in the new edition of Nature Climate Change and says carbon labelling will help reduce carbon emissions.
