Number of extreme heat days over land continuing to increase

February 26th, 2014 by Nature Climate Change

There has been a continued increase in the number of extreme heat days over land since 1997. This finding, reported in a Commentary in the March 2014 issue of Nature Climate Change, suggests that the increase is in spite of the recent slowdown in global average surface temperature. A team of researchers, led by Professor […]

Producing hydrogen from methanol efficiently using a new catalyst

March 5th, 2013 by Nature

An efficient, low-temperature method for generating hydrogen from methanol is described in Nature. The hydrogen gas produced using this method can be converted into electricity with the help of proton-exchange membrane (PEM) fuel cells. Hydrogen produced from renewable resources is a promising potential source of clean energy. Unfortunately, hydrogen gas is difficult to handle and […]

Guernsey Conservation Volunteers give reeds a chance at Marais Rise

October 28th, 2012 by Richard Lord

The Guernsey Conservation Volunteers worked at Marais Rise reed bed close to Belle Greve Bay on the invigorating sunny and windy morning of Saturday 27 October 2012. The Marais Rise reed bed is States of Guernsey land that the Guernsey Conservation Volunteers work to maintain and manage. The volunteers have worked on the Marais Rise […]

Nature improves a child’s emotional well-being & academic performance

July 26th, 2012 by Planet Ark

While the vast majority who regularly care for children agree that contact with nature is good for children’s well-being and development, they don’t know that green time can significantly improve the academic performance of their children. This is just one of the key findings of an independent study commissioned by Planet Ark and sponsored by […]

Humans making global ecosystem vulnerable to tipping point

June 10th, 2012 by Nature

Nature presents confirmation that the global ecosystem is approaching a transition, highlighting the need to improve forecasting and address human influences on such changes. The Review, ‘Approaching a state shift in Earth’s biosphere‘ summarizes evidence that similar shifts have occurred in the past, and that humans are driving the most recent changes. The realization that […]

Antarctic ice sheet may melt more rapidly with thinning of ice shelf

May 10th, 2012 by Alfred Wegener Institute for Polar and Marine Research

The Filchner-Ronne Ice Shelf fringing the Weddell Sea, Antarctica, may start to melt rapidly in this century and no longer act as a barrier for ice streams draining the Antarctic Ice Sheet. These predictions are made by climate researchers of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association in the […]

Global oil production can no longer keep up if demand continues to rise

January 27th, 2012 by Nature

The impact of dwindling oil supplies on the economy is a persuasive argument for shifting away from fossil fuels, write Professor James Murray and Sir David King in a Comment piece in Nature published on 26 January 2012. There was a ‘tipping point’ for oil in 2005. Before then,

Permafrost carbon release is an important climate change amplifier

December 4th, 2011 by Institute of Arctic Biology

As the Arctic warms, greenhouse gases will be released from thawing permafrost faster and at significantly higher levels than previous estimates, according to survey results from 41 international scientists published in the 30 November 2011 issue of the journal Nature. Permafrost thaw will release approximately the same amount of carbon as deforestation, say the authors, […]

Shrinking body size an ecological response to climate change

November 24th, 2011 by Nature

Organisms from primary producers to top predators are shrinking in size in response to climate change, according to a Perspective published in Nature Climate Change. It is well established that species are shifting their distributions to higher elevations and latitudes in response to warming, and that key life events such as migration are happening earlier […]

Civil conflicts are twice as likely to occur during El Niño years

September 19th, 2011 by Nature

Civil conflicts are twice as likely to occur during El Niño years, when conditions are typically warmer, than in cooler La Niña years, suggests a paper published in the 25 August 2011 issue of Nature. This is the first demonstration that the stability of modern societies relates strongly to global climates.
