Fracking prompts global spike in atmospheric methane – “This recent increase in methane in massive”

By Blaine Friedlander 14 August 2019 (Cornell Chronicle) – As methane concentrations increase in the Earth’s atmosphere, chemical fingerprints point to a probable source: shale oil and gas, according to new Cornell research published 14 August 2019 in Biogeosciences, a journal of the European Geosciences Union. The research suggests that this methane has less carbon-13 relative […]

World food security increasingly at risk due to “unprecedented” climate change impact, new UN report warns

8 August 2019 (UN News) – More than 500 million people today live in areas affected by erosion linked to climate change, the UN warned on Thursday, before urging all countries to commit to sustainable land use to help limit greenhouse gas emissions before it is too late. Speaking at the launch of a Special […]

Taking Stock 2019: U.S. on track to miss Paris Agreement climate goal by wide margin

By Hannah Pitt, Kate Larsen, Hannah Kolus, Shashank Mohan, John Larsen, Whitney Herndon, and Trevor Houser 8 July 2019 (Rhodium Group) – For the past five years, Rhodium has provided an independent annual assessment of US greenhouse gas (GHG) emissions and progress towards achieving the country’s climate goals. Given the current state and federal policy […]

Unexpected consequences from catastrophic mangrove dieback – “What was concerning was that the dead mangrove forest emitted about eight times more methane than the living forest”

4 July 2019 (Southern Cross University) – When swathes of mangrove forests died along a 1000 kilometre stretch of coastline in northern Australia’s Gulf of Carpentaria, there was widespread shock. But the impacts of the catastrophic climate-induced mangrove dieback didn’t end there. In a world first, researchers from Southern Cross University have found that the […]

Leaving microbes out of climate change conversation has major consequences, experts warn – “Climate change is literally starving ocean life”

By Ivy Shih 19 June 2019 (UNSW) – An international group of leading microbiologists have issued a warning, saying that not including microbes – the support system of the biosphere – in the climate change equation will have major negative flow-on effects. More than 30 microbiologists from 9 countries have issued a warning to humanity […]

Arctic permafrost melting 70 years sooner than expected, study finds – “This change is unprecedented on this kind of time scale”

By Jan Wesner Childs 14 June 2019 (The Weather Channel) – Scientists studying climate change expected layers of permafrost in the Canadian Arctic to melt by the year 2090. Instead, it’s happening now. A new study published this week in the journal Geophysical Research Letters revealed that unusually warm summers in the Canadian High Arctic between 2003 […]

Industrial methane emissions are 100 times higher than reported, researchers say

By Amanda Garris 6 June 2019 (Cornell Chronicle) – Emissions of methane from the industrial sector have been vastly underestimated, researchers from Cornell and Environmental Defense Fund have found. Using a Google Street View car equipped with a high-precision methane sensor, the researchers discovered that methane emissions from ammonia fertilizer plants were 100 times higher […]

The methane detectives: On the trail of a global warming mystery – “The bottom line is that methane is going up and doesn’t look like it will stop anytime soon”

By Jonathan Mingle 13 May 2019 (Undark) – Every week, dozens of metal flasks arrive at NOAA’s Earth System Research Laboratory in Boulder, Colorado, each one loaded with air from a distant corner of the world. Research chemist Ed Dlugokencky and his colleagues in the Global Monitoring Division catalog the canisters, and then use a series of […]

Power companies have a plan to save the earth, but it probably won’t work – “In the absence of some kind of national program or policy, we shouldn’t expect to see some dramatic decline in emissions”

By Neil Katz and Joe McCarthy 9 May 2019 (The Weather Channel) – Last month, a thousand well-heeled bankers, scrappy startups and energy CEOs sat down at the Bloomberg New Energy Finance conference in a swanky New York hotel to discuss the billions they would spend over the next 20 years to build cleaner energy […]

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 […]
