Baltic Sea clams ‘giving off as much gas as 20,000 cows’

SOURCE: BBC News DATE: October 13, 2017 SNIP: Scientists have found clams and worms in the Baltic Sea are giving off as much gas as 20,000 dairy cows. They are worried because large amounts of methane and nitrous oxides are being released from the bacteria in their guts. The discovery of these greenhouse gases means they will need to be taken into account when tackling global warming. A Cardiff and Stockholm universities’ study found 10% of methane emissions from the Baltic Sea came from clams. The study’s co-author Dr Ernest Chi Fru, from Cardiff University’s School of Earth and Ocean Sciences, said: “What is puzzling is that the Baltic Sea makes up only about 0.1% of Earth’s oceans, implying that globally, apparently harmless bivalve animals at the bottom of the world’s oceans may in fact be contributing ridiculous amounts of greenhouse gases to the atmosphere that is unaccounted...

Germany to miss climate targets ‘disastrously’: leaked government paper

SOURCE: Climate Change News DATE: October 11, 2017 SNIP: Germany is headed for a clear failure to meet its 2020 climate targets, according to calculations by the country’s environment ministry. Without further action, Germany’s CO2 emissions will only be 31.7% to 32.5% below 1990 levels, an internal environment ministry paper seen by the Clean Energy Wire shows. Given the official target of cutting emissions by 40%, the ministry warns that a failure of this magnitude would constitute a “significant blow to Germany’s climate policy”, and would amount to “a disaster for Germany’s international reputation as a climate...
‘Dodgy’ greenhouse gas data threatens Paris accord

‘Dodgy’ greenhouse gas data threatens Paris accord

SOURCE: BBC DATE: Aug 8, 2017 SNIP: Potent, climate-warming gases are being emitted into the atmosphere but are not being recorded in official inventories, a BBC investigation has found. Air monitors in Switzerland have detected large quantities of one gas coming from a location in Italy. However, the Italian submission to the UN records just a tiny amount of the substance being emitted. Levels of some emissions from India and China are so uncertain that experts say their records are plus or minus 100%. Prof Glen Peters, from the Centre for International Climate Research, in Oslo, said: “The core part of Paris [is] the global stock-takes which are going to happen every five years, and after the stock-takes countries are meant to raise their ambition, but if you can’t track progress sufficiently, which is the whole point of these stock-takes, you basically can’t do anything. “So, without good data as a basis, Paris essentially collapses. It just becomes a talkfest without much...
How frozen farmers’ fields are an unexpected culprit in climate change, according to a new study

How frozen farmers’ fields are an unexpected culprit in climate change, according to a new study

SOURCE: National Post DATE: April 11, 2017 SNIP: Across Canada, the last of the snow and ice is melting away from a vast expanse of farmers’ fields, making way for the planting of this year’s crops. And — suggests a new Canadian study — making an unexpectedly large contribution to greenhouse gases and climate change. Strange as it might seem, the thawing of frozen cropland burps nitrous oxide into the atmosphere at rates far greater than previously thought, meaning agriculture’s role in producing the greenhouse gas has been greatly underestimated, according to research from the Universities of Guelph and Manitoba. Nitrous oxide — commonly known as laughing gas and used as a dental anesthetic — accounts for well under 10 per cent of greenhouse gas emissions. But it’s almost 300 times as potent as carbon dioxide at trapping energy, the greenhouse effect believed to be warming the...
Effect of methane on climate change could be 25% greater than we thought

Effect of methane on climate change could be 25% greater than we thought

SOURCE: Phys.org DATE: January 10, 2017 SNIP: Methane emissions caused by human activity may have a bigger impact on global warming than previously thought, scientists have found. Research led by the University of Reading indicates that emissions of methane due to human activity have, to date, caused a warming effect which is about one-third of the warming effect due to carbon dioxide emissions – this methane contribution is 25% higher than previous estimates. The scientists calculated that, while carbon dioxide remains by far the most significant gas driving human-induced climate change, methane, while much less abundant, is even more potent than previously thought. They found that a one tonne emission of methane has the equivalent warming effect of 32 tonnes of carbon dioxide – up from the previous estimate of...
