Climate change in the far north is occurring far more rapidly than elsewhere around the planet, but common-sense efforts to mitigate key emissions and protect the fragile Arctic environment could slow this trend and benefit communities, the environment, and companies.
Researchers in the University of Bristol’s Atmospheric Chemistry Research Group (ACRG), in collaboration with scientists around the country, have been awarded funding from the Natural Environment Research Council (NERC) to provide an independent 'top-down' check on the UK's greenhouse gas emissions estimates.
Climate change and droughts in Brazil will decrease the potential of hydroelectric energy and increase demand for energy from alternative sources, particularly thermoelectric energy from natural gas. Regulations favorable for free contracting will further boost the Brazilian natural gas power plant market.
The Centre for Carbon Measurement at the National Physical Laboratory (NPL) will deliver eight megatonnes of carbon emissions reductions and over half a billion pounds in economic benefit over the next decade, according to an independent report. This is a level of carbon saving is equivalent to 2% of the UK's annual carbon footprint.
Abnormal climatic conditions in the Indian and Pacific Oceans during the 2010-2011 La Niña event combined to create the extreme marine heatwave seen off the Western Australia coast in 2011, according to new research published in Nature Scientific Reports.
Researchers at Plymouth University, UK, believe that findings from fieldwork along the North Yorkshire coast reveal strong parallels between the Early Jurassic era of 180 million years ago and current climate predictions over the next century.
Sophisticated computer modelling has shown how sea-level rise over the coming century could affect some regions far more than others. The model shows that parts of the Pacific will see the highest rates of rise while some polar regions will actually experience falls in relative sea levels due to the ways sea, land and ice interact globally.
In his Feb. 12 State of the Union address, President Obama singled out climate change as a top priority for his second administration. "We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence," he said. "Or we can choose to believe in the overwhelming judgment of science ¨C and act before it's too late."
Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and, if exposed to the surface when long-frozen soils melt and collapse, can release climate-warming carbon dioxide gas into the atmosphere much faster than previously thought.
Cities are major players in the climate change game. More than half of the world's population lives in urban areas and over 70% of global GHG (greenhouse gas) emissions can be attributed to cities. A case study of Toronto demonstrates alternative strategies for how the city can implement a low carbon urban infrastructure plan by 2031.
