The world is getting windier

The world is getting windier

Posted Fri, 08 Apr 2011 15:27:00 GMT by Laura Brown

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.

Slow-onset climate change could have 'potentially catastrophic' long-term impact on food production in the developed world

Slow-onset climate change could have 'potentially catastrophic' long-term impact on food production in the developed world

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.

Jet contrails major contributor to aviation's effect on climate

Jet contrails major contributor to aviation's effect on climate

Posted Tue, 29 Mar 2011 10:01:01 GMT by Louise Murray

Cirrus clouds generated from the contrails of jets may be the cause of more atmospheric warming today than all the CO2 emitted by the aviation industry since the beginning of flight. Aviation is responsible for about 5% of man-made climate change effects, and that proportion could triple by 2050 according to some projections. Least understood is the role of aircraft exhausts in forming clouds.

Scientists have discovered that the movement and melting of icebergs plays an important role in distributing phytoplankton and consequently absorbing and removing carbon dioxide from the oceans. The new findings have major implications for global climate research and management.

Decreasing CO2 concentrations in the atmosphere causes more rain to be wrung from the clouds, according to research published in Geophysical Research Letters. That change in rainfall can go both ways, with decreasing precipitation as CO2 levels rise - and it happens faster than the overall global change in temperature.

March's Arctic winter-ice peak has just been called by the NSDIC, and it's low. This year's level is tied with the lowest ever recorded sea-ice extent - also seen this decade in 2006. The Arctic is probably seeing the fastest rates of change due to global warming, marking it out as an early warning of the dangers faced. Will anyone listen before this canary keels over?

Climate Change Has Huge Effect On Birdlife

Climate Change Has Huge Effect On Birdlife

Posted Thu, 24 Mar 2011 12:27:00 GMT by Kieran Ball

Climate change is having a bigger effect than previously thought on bird species. There is no doubt that climate change is affecting many ecological events, such as flowering and reproduction seasons in animals. In the case of birdlife, there is growing evidence that this effect is particularly profound.

Biofuels may not be as green as you might think - new study sheds light on 'con'

Biofuels produced in Africa but destined for use in Europe will result in up to six times the carbon emissions of fossil fuels, according to a new report. Some species of the succulent Jatropha genus are widely promoted as easily grown crops, and oil from the seeds is used extensively in many developing countries to produce biofuel. However, the new report contradicts the 'green image' of biofuels, which are widely considered to be a renewable alternative to fossil fuels.

Earth Hour annual event to raise the profile of climate change faces criticism. Started in 2007, Earth Hour might be facing a ticking clock. Criticism is growing. There are allegations of ''tokenism'' and that it is an ineffectual response. A darling of large corporations who want to align themselves with a brand to increase their green credibility might be, in themselves damaging what began as an underground zeitgeist.

A review of Antarctic ice cores by German physicists, leads to an expansion of the accepted hypothesis of climatic history. Researchers have reconstructed temperature fluctuations in Antarctica for the last million years by studying ice cores. Up until now the presumption has been that these fluctuations were triggered by the global effect of climatic changes in the northern hemisphere.

Extreme weather motivates greener behaviour

Extreme weather motivates greener behaviour

People who live through extreme weather catastrophes are more concerned about climate change and are more willing to adopt greener habits to help tackle it, say environmental behaviour scientists. Researchers at the Universities of Cardiff and Nottingham suggest that when individuals have experienced extreme weather events in their local area, such as flooding, they are more prepared to reduce how much energy they use in an effort to minimise climate change.
