Think Geoengineering is a quick fix for global warming?
November 26, 2014 09:20 AM - University of Bristol
The deliberate, large-scale intervention in the Earth’s climate system is not a “quick fix” for global warming, according to the findings of the UK’s first publicly funded studies on geoengineering.
The results of three projects – IAGP, led by the University of Leeds; SPICE, led by the University of Bristol; and CGG, led by the University of Oxford – are announced at an event held at The Royal Society, London, on 26 November.
Climate change, species extinctions and tipping points
November 25, 2014 07:35 AM - North Carolina State University via EurekAlert.
Researchers from North Carolina State University have created a model that mimics how differently adapted populations may respond to rapid climate change. Their findings demonstrate that depending on a population's adaptive strategy, even tiny changes in climate variability can create a "tipping point" that sends the population into extinction.
Carlos Botero, postdoctoral fellow with the Initiative on Biological Complexity and the Southeast Climate Science Center at NC State and assistant professor of biology at Washington State University, wanted to find out how diverse populations of organisms might cope with quickly changing, less predictable climate variations.
World Bank warns effects of warming climate now unavoidable
November 24, 2014 11:29 AM - , ClickGreen
As the planet continues to warm, heat-waves and other extreme weather events that today occur once in hundreds of years, if ever, will become the “new climate normal,” creating a world of increased risks and instability, a new World Bank study warns.
The consequences for development would be severe as crop yields decline, water resources shift, sea-levels rise, and the livelihoods of millions of people are put at risk, according to a new scientific report released today by the World Bank Group.
Can Volcanic Eruptions Slow Global Warming?
November 21, 2014 02:34 PM - American Geophysical Union
Small volcanic eruptions might eject more of an atmosphere-cooling gas into Earth’s upper atmosphere than previously thought, potentially contributing to the recent slowdown in global warming, according to a new study.
Farms as sites for renewable energy
November 21, 2014 07:00 AM - ClickGreen Staff, ClickGreen
UK farms could be a major player in a shift towards a resilient, low-carbon energy system, according to a landmark report launched today by the Farm Power coalition.
The coalition, which is made up of a growing number of farming bodies, businesses and NGOs, are now calling on policymakers and other key stakeholders, including supermarkets, to support the renewable energy vision.
The research carried out by sustainability non-profit Forum for the Future, which leads the coalition, and Nottingham Trent University, found there was at least 10GW of untapped resource across UK farms – equivalent to more than three times the installed capacity of the proposed new nuclear power plant at Hinkley Point C.
Not so fast: Planting trees might cause warming?
November 20, 2014 03:29 PM - Bristol University
Afforestation (planting trees) to mitigate climate change could cause warming rather than cooling globally due to non-carbon effects of land use change, according to new research from the University of Bristol.
Global land use change and its interaction with the climate system is recognised as an important component of the Intergovernmental Panel on Climate Change (IPCC)’s future climate scenarios.
Abrupt rise in greenhouse gases at end of last ice age may be because of permafrost
November 20, 2014 12:30 PM - Alfred Wegener Institute
One of the most abrupt rises in the carbon dioxide concentration in the atmosphere at the end of the last ice age took place about 14,600 years ago. Ice core data show that the CO2 concentration at that time increased by more than 10 ppm (parts per million, unit of measure for the composition of gases) within 200 years. This CO2 increase, i.e. approx. 0.05 ppm per year, was significantly less than the current rise in atmospheric CO2 of 2-3 ppm in the last decade caused by fossil fuels.
EU Court Rules Against UK For Failure to Tackle Air Pollution
November 19, 2014 11:57 AM - Keith Taylor, MEP, The Ecologist
A landmark judgment by the European Court of Justice compels the UK Government to act as soon as possible to reduce air pollution in British cities, writes Keith Taylor - and a good thing too for our health, safety and wellbeing. But it's not just the UK that benefits: every EU country must also comply with the ruling.
Climate history of western US is more complex than previously thought
November 19, 2014 10:54 AM - Southern Methodist University
The climate 150 million years ago of a large swath of the western United States was more complex than previously known, according to new research from Southern Methodist University, Dallas. It’s been held that the climate during the Jurassic was fairly dry in New Mexico, then gradually transitioned to a wetter climate northward to Montana. But based on new evidence, the theory of a gradual transition from a dry climate to a wetter one during the Jurassic doesn’t tell the whole story, says SMU paleontologist Timothy S. Myers, lead author on the study.
Researchers use social media to track air pollution
November 18, 2014 11:13 AM - Jennifer Smith, University of Wisconsin-Madison
University of Wisconsin-Madison computer science researchers have developed a method for using social media posts to estimate air pollution levels with significant accuracy.
