Nutritional quality of food crops decreases as CO2 levels rise
April 7, 2014 08:02 AM - ClickGreen Staff, ClickGreen
A field test has demonstrated for the first time that elevated levels of carbon dioxide restrict plants' ability to transform nitrate into proteins, indicating that the nutritional quality of food crops is at risk as climate change intensifies.
Wild Bees Improve Farm Revenues by Boosting Crop Yields
April 3, 2014 01:09 PM - Click Green Staff, ClickGreen
Investing in habitat that attracts and supports wild bees in farms is not only an effective approach to helping enhance crop pollination, but it can also pay for itself in four years or less, according to Michigan State University research. The paper, published in the current issue of the Journal of Applied Ecology, gives farmers of pollination-dependent crops tangible results to convert marginal acreage to fields of wildflowers, said Rufus Isaacs, MSU entomologist and co-author of the paper.
NASA study finds Arctic melt is now 15 days longer than 30 years ago

The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness, according to a new study by National Snow and Ice Data Center (NSIDC) and NASA researchers.
Meeting climate targets may require reducing diet of meat and dairy

Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to research at Chalmers University of Technology in Sweden.
Antarctic ice study reveals accelerated sea level rise

Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research. The amount of ice draining collectively from those half-dozen glaciers increased by 77 percent from 1973 to 2013, scientists report this month in Geophysical Research Letters, a journal of the American Geophysical Union.
Paintings Help Chart History of Air Pollution

An international research team has shown that the colors of sunsets painted by famous artists can be used to estimate pollution levels in the Earth's atmosphere. The paintings reveal that ash and gas released during major eruptions scatter the different colors of sunlight, making sunsets appear more red.
British bird is an unlikely winner from changing climate
March 24, 2014 08:16 AM - ClickGreen Staff, ClickGreen
Climate change may be bad news for billions, but scientists at the University of Sheffield have discovered one unlikely winner — a tiny British bird, the long-tailed tit. Like other small animals that live for only two or three years, these birds had until now been thought to die in large numbers during cold winters. But new research suggests that warm weather during spring instead holds the key to their survival.
Nissan LEAF drivers save big!

Drivers of the world’s best-selling electric car, the Nissan LEAF, are edging towards the milestone of clocking up 1 billion kilometres of low-cost, low-carbon motoring. Owners of more than 100,000 Nissan LEAFs worldwide have now collectively saved over £50 million through cheaper fuelling costs and are responsible for removing 204,000 tonnes of potential CO2 emissions from the environment.
Inundaciones en Gran Bretaña: ¿señal de eventos por venir?
March 21, 2014 08:02 PM - ClickGreen Staff, ClickGreen
Una nueva investigación basada en registros climáticos de largo plazo sugiere que la reciente inundación en el sur de Inglaterra pudiera ser un indicio del comienzo del cambio climático. El estudio, realizado por la Universidad del Oeste de Inglaterra en Bristol (UWE Bristol), la Universidad de Loughborough y la Universidad de East Anglia ha producido un nuevo índice de las tendencias de inundaciones llamada el índice de Inundaciones Fluviales. Esto permite visualizar los patrones climáticos y de inundaciones generalizados en el contexto de los últimos 150 años, que revela que cuatro de los seis episodios de inundaciones más graves desde 1871 se han producido en los últimos 30 años. Este nuevo índice fue desarrollado por el Profesor Rob Wilby de la Universidad de Loughborough y el Profesor Adjunto Nevil Quinn de la UWE Bristol y fue publicado en el Journal de Hidrología del año pasado. Con la colaboración del Dr. Colin Harpham de la Universidad de East Anglia, el índice ha sido actualizado para cubrir las inundaciones más recientes.
Floods in Britain: a sign of things to come?
March 20, 2014 11:52 AM - ClickGreen Staff, ClickGreen
A new investigation of long-term weather records suggests that the recent flooding in the south of England could signal the onset of climate change. The research, from UWE Bristol, Loughborough University and the University of East Anglia has produced a new index of flooding trends called the Fluvial Flood Indices. This enables widespread flooding and weather patterns to be viewed in the context of the last 150 years, revealing that four of the six most severe flood episodes since 1871 have occurred in the last 30 years.
