Global hydropower boom will add to global warming – “Reservoirs are major emitters of methane, a particularly aggressive greenhouse gas”

By Claire Salisbury14 February 2017 (Mongabay) – From the Amazon Basin to boreal forests, and from the Mekong to the Himalayan foothills, rivers worldwide are being targeted for major new dams in a global hydropower boom that also aims to supply drinking water to exploding human populations and to facilitate navigation on the planet’s rivers; […]

U.S. unlikely to make significant gains in reducing greenhouse gas emissions and may become net energy exporter

By Bobby Magill5 January 2017 (Climate Central) – The amount of energy Americans use and the pollution they emit from using coal, oil, and natural gas are not likely to change radically over the next 30 years, even as the U.S. becomes a major energy exporter, according to the U.S. Energy Information Administration’s Annual Energy […]

Short-lived greenhouse gases cause centuries of sea-level rise

By Jennifer Chu9 January 2017 (MIT News) – Even if there comes a day when the world completely stops emitting greenhouse gases into the atmosphere, coastal regions and island nations will continue to experience rising sea levels for centuries afterward, according to a new study by researchers at MIT and Simon Fraser University. In a […]

Lake Baikal sponge has died out completely in several areas

By Olga Gertcyk20 December 2016 (The Siberian Times) – In just two years, since the sponge was last surveyed, it has entirely vanished in the area around popular tourist resort Listvyanka and Cape Tolsty, in Irkutsk region, and over a wide area in the north of the crescent-shaped lake which contains around 20% of the […]

Methane emissions spiking globally, now approaching the most greenhouse gas-intensive scenarios

By Stephanie Smail12 December 2016 (ABC) – Global methane gas emissions are growing at the fastest rate in decades and food production could be to blame, new analysis has revealed. Nearly 100 scientists from around the world have compiled data for the Global Methane Budget, which shows the biggest spike in methane concentrations in the […]

EPA concludes fracking can threaten water supplies

[Expect these sorts of studies to stop when Scott Pruitt, longtime enemy of the EPA and Trump’s selection to head the EPA, takes control. –Des] By Patrick G. Lee14 December 2016 (ProPublica) – Starting in 2008, ProPublica published stories that found hydraulic fracking had damaged drinking water supplies across the country. The reporting examined how […]

Reservoirs are underappreciated source of greenhouse gases

By Eric Sorensen28 September 2016 VANCOUVER, Washington (WSU News) – Washington State University researchers say the world’s reservoirs are an underappreciated source of greenhouse gases, producing the equivalent of roughly 1 gigaton of carbon dioxide a year, or 1.3 percent of all greenhouse gases produced by humans. That’s more greenhouse gas production than all of […]

Graph of the Day: NOAA annual greenhouse gas index (AGGI), 1700-2015

30 April 2016 (NOAA) – The annual greenhouse gas index (AGGI) is a measure of the warming influence of long-lived trace gases and how that influence is changing each year. The index was designed to enhance the connection between scientists and society by providing a normalized standard that can be easily understood and followed. The […]

In new ozone alert, a warning of harm to plants and to people – ‘We are on track to return to the maximum ethane levels we saw in the 1970s in only about three more years’

By Jim Robbins17 October 2016 (Yale e360) – For the last four years Jack Fishman, a professor of meteorology at St. Louis University, has guided the planting of five gardens in the Midwest, gardens that have a distinct purpose: to show the impacts of an invisible gas that is damaging and contributing to the premature […]

Arctic methane gas emission significantly increased since 2014 – ‘The rate of degradation of underwater permafrost has increased’

  4 October 2016 (Siberian Times) – A new expedition in the Laptev Sea suggests an increase in the rate of underwater permafrost degradation. The findings come from an expedition now underway led by Professor Igor Semiletov, of Tomsk Polytechnic University, on the research vessel Academic M.A. Lavrentyev which left Tiksi on 24 September 2016 […]
