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 […]

Canada approves $36 billion LNG ‘carbon bomb’ on B.C. coast

By Derrick O’Keefe27 September 2016 (Ricochet) – On Tuesday evening in Richmond, B.C., three members of Prime Minister Justin Trudeau’s cabinet announced the approval of a $36-billion liquefied natural gas development by the Malaysian-based multinational corporation Petronas, which would see natural gas moved by pipeline from the province’s northeast to a terminal on the coast, […]

Aquatic plants may accelerate Arctic methane emissions

[Keep in mind that Eos is a publication of AGU, which has voted to continue receiving sponsorship from the fossil-fuel industry. – Desdemona] By Rebecca Heisman22 September 2016 (Eos) – Climate change has caused a boom in aquatic plant biomass on the Arctic tundra in recent decades. Those plants, in turn, are releasing increasing amounts […]

Is natural gas a viable bridge fuel?

[cf. Our leaders thought fracking would save our climate – ‘Methane emissions are substantially higher than we’ve understood’] By Zeke Hausfather23 August 2016 (Yale Climate Connections) – For the past century, coal has been king, providing the majority of U.S. energy for electricity generation. But a combination of new federal and state environmental policies and […]

NASA study analyzes Four Corners methane leaks – Some sources emit up to 5,000 kilograms per hour

15 August 2016 (NASA) – In an extensive airborne survey, a NASA-led team has analyzed a previously identified “hot spot” of methane emissions in the Four Corners region of the United States, quantifying both its overall magnitude and the magnitudes of its sources. The study finds that just 10 percent of the individual methane sources […]

Clean energy won’t save us – only a new economic system can

By Jason Hickel15 July 2016 (Guardian) – Earlier this year, media outlets around the world announced that February had broken global temperature records by a shocking amount. March broke all the records too. In June, our screens were covered with surreal images of flooding in Paris, the Seine bursting its banks and flowing into the […]

Video: Underground methane bubbles and trembling tundra in Siberia’s land of mysterious craters

20 July 2016 (Siberian Times) – Earth is moving as ‘leaking methane gas due to global warming causes surface to bubble’ in a new phenomenon. This extraordinary sight – in a video filmed of the tundra on remote Belyy Island in the Kara Sea off the Yamal Peninsula coastline – was witnessed by a scientific […]

Graph of the Day: World primary energy consumption, 1990-2015

9 June 2016 (BP) – World primary energy consumption grew by a below-average 1.0% in 2015, the slowest rate of growth since 1998 (other than the decline in the aftermath of the financial crisis). Growth was below average in all regions except Europe and Eurasia. All fuels except oil and nuclear power grew at below-average […]
