Climate impacts of super-giant oilfields go up with age

17 July 2017 By Ker Than (Stanford News) – Even oilfields aren’t immune to the ravages of time: A new study finds that as some of the world’s largest oilfields age, the energy required to keep them operating can rise dramatically even as the amount of petroleum they produce drops.Failing to take the changing energy […]

Carbon in atmosphere is rising, even as emissions stabilize

By Justin Gillis 26 June 2017 CAPE GRIM, Tasmania (The New York Times) – On the best days, the wind howling across this rugged promontory has not touched land for thousands of miles, and the arriving air seems as if it should be the cleanest in the world. But on a cliff above the sea, […]

Burning fossil fuels almost ended all life on Earth – “It should be a national priority to study the Permian to figure out what the hell happened”

By Peter Brannen 11 July 2017 (The Atlantic) – “Who you with?” “I’m a science journalist,” I said, jolted from my reverie on the shoulder of I-68 in Maryland, where a crowd of geologists had gathered on a field trip to poke at some rocks revealed by the highway department’s dynamite. The rocks, slate gray […]

NOAA’s greenhouse gas index up 40 percent since 1990 – Carbon dioxide increase is accelerating

11 July 2017 (NOAA) – NOAA’s Annual Greenhouse Gas Index, which tracks the warming influence of long-lived greenhouse gases, has increased by 40 percent from 1990 to 2016 — with most of that attributable to rising carbon dioxide levels, according to NOAA climate scientists. [cf. Graph of the Day: NOAA annual greenhouse gas index (AGGI), […]

Three years to safeguard our climate

By Christiana Figueres, Hans Joachim Schellnhuber, Gail Whiteman, Johan Rockström, Anthony Hobley, and Stefan Rahmstorf 28 June 2017 (Nature) – In the past three years, global emissions of carbon dioxide from the burning of fossil fuels have levelled after rising for decades. This is a sign that policies and investments in climate mitigation are starting […]

“Full toolbox” needed to solve global warming – “Our energy system is leaking waste carbon dioxide into the atmosphere”

Washington, DC, 19 June 2017 (Carnegie Institution For Science) – Solving the climate change problem means transitioning to an energy system that emits little or no greenhouse gases into the atmosphere. According to new work from a team of experts including Carnegie’s Ken Caldeira, achieving a near-zero-emissions energy system will depend on being able to […]

Scientists throw light on mysterious ice age temperature jumps – “A gradual rise of CO2 within the atmosphere can hit a tipping point, triggering abrupt temperature shifts that drastically affect the climate across the Northern Hemisphere”

20 June 2017 (Cardiff University) – Scientists believe they have discovered the reason behind mysterious changes to the climate that saw temperatures fluctuate by up to 15°C within just a few decades during the ice age periods. In a new study published today, the researchers show that rising levels of CO2 could have reached a […]

Australia carbon emissions rise in off-season for first time in a decade

By Michael Slezak and Nick Evershed 7 June 2017 (The Guardian) – Australia’s carbon emissions jumped at the start of 2017, the first time they have risen in the first few months of a year for more than a decade, according to projections produced exclusively for the Guardian.Emissions in the first three months of the […]

Peatlands, already dwindling, could face further losses – “There is a tremendous amount of peatland in Southeast Asia, but almost all of it has been deforested”

By David Chandler 12 June 2017 (MIT News) – Tropical peat swamp forests, which once occupied large swaths of Southeast Asia and other areas, provided a significant “sink” that helped remove carbon dioxide from the atmosphere. But such forests have been disappearing fast due to clear-cutting and drainage projects making way for plantations. Now, research […]

India hits back at Trump in war of words over global warming – “There is absolutely no reality in what Trump alleged”

By Huizhong Wu 6 June 2017New Delhi (CNN) – India has hit back at US President Donald Trump, after he accused the country of receiving “billions” of dollars in return for signing the Paris Agreement on Climate Change.”First of all, there is absolutely no reality [in what Trump alleged],” India’s Foreign Minister Sushma Swaraj told […]
