The cost of living in the Anthropocene

What are the true cost of living in the Anthropocene? Wikipedia: The Anthropocene is an informal geologic chronological term that serves to mark the evidence and extent of human activities that have had a significant global impact on the Earth‘s ecosystems. The term was coined recently by ecologist Eugene F. Stoermer and has been widely popularized by the Nobel Prize-winning atmospheric chemist, Paul Crutzen, who regards the…

Global Warming Speeds Up Methane Emissions from Freshwater

By Tim Radford (Climate News Network): Scientists think the amount of methane emitted to the atmosphere from freshwater ecosystems will increase as the climate warms, triggering further warming. LONDON, 20 March – British scientists have identified yet another twist to the threat of global warming. Any further rises in temperature are likely to accelerate the release of methane from…

Volcanic Eruptions Add to Larger Impact on Climate

The recent slow down in global warming has been attributed to a number of factors, including excess heat being stored in the deep ocean and reductions of certain greenhouse gases. Now add volcanic eruptions to the mix of contributing factors. A new analysis published in Nature Geosciences on Sunday shows that a series of relatively small…

U.S. Methane Emissions are 50% Higher than Official Estimates

America’s natural gas system is leaky and in need of a fix, new study finds A review of more than 200 earlier studies confirms that U.S. emissions of methane are considerably higher than official estimates. Leaks from the nation’s natural gas system are an important part of the problem. This finding has important implications for…
