Volcanic eruptions drove ancient global warming event

Warming event that took place 56 million years ago led to significant ecological disruption and could shed light on modern climate change By Sarah Nightingale 30 August 2017 RIVERSIDE, California (UCR Today) – A natural global warming event that took place 56 million years ago was triggered almost entirely by volcanic eruptions that occurred as […]

Alaska’s permafrost is thawing – “It’s sobering to think of this magnificent landscape and how fundamentally it can change over a relatively short time period”

By Henry Fountain 23 August 2017 YUKON DELTA NATIONAL WILDLIFE REFUGE, Alaska (The New York Times) – The Arctic is warming about twice as fast as other parts of the planet, and even here in sub-Arctic Alaska the rate of warming is high. Sea ice and wildlife habitat are disappearing; higher sea levels threaten coastal […]

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 […]

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 […]

Tiny shells indicate big changes to global carbon cycle – Ocean acidification “affects atmospheric and ocean carbon dioxide concentrations on time scales of thousands of years”

By Kat Kerlin 25 May 2017 (UC Davis) – Experiments with tiny, shelled organisms in the ocean suggest big changes to the global carbon cycle are underway, according to a study from the University of California, Davis.For the study, published in the journal Scientific Reports, scientists raised foraminifera — single-celled organisms about the size of […]

Jurassic drop in ocean oxygen lasted a million years

12 May 2017 (University of Exeter) – Dramatic drops in oceanic oxygen, which cause mass extinctions of sea life, come to a natural end – but it takes about a million years. The depletion of oxygen in the oceans is known as “anoxia”, and scientists from the University of Exeter have been studying how periods […]

Global warming could destroy far more Arctic permafrost than we thought – “The current pattern of permafrost reveals the sensitivity of permafrost to global warming”

By Chelsea Harvey 10 April 2017 (The Washington Post) – Climate change could cause another 4 million square kilometers, or about 1.5 million square miles, of permafrost to disappear with every additional degree Celsius, or 1.8 degrees Fahrenheit, of warming, a new study suggests. The estimate, which was published Monday in the journal Nature Climate […]

Video: “First protest in space” targets Trump with an astronaut’s famous words

By Ben Guarino 14 April 2017 (The Washington Post) – On Wednesday, 12 April 2017, 56 years to the day after Russian cosmonaut Yuri Gagarin became the first human in space, a Phoenix-based collective called the Autonomous Space Agency Network launched a weather balloon to about 90,000 feet. The balloon, Aphrodite 1, weighed a little […]

Soils could release much more carbon than expected as climate warms – “By 2100, the warming of deeper soil layers could cause a release of carbon perhaps as high as 30 percent of today’s human-caused annual carbon emissions”

By Dan Krotz9 March 2017 (Berkeley Lab) – Soils could release much more CO2 than expected into the atmosphere as the climate warms, according to new research by scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). Their findings are based on a field experiment that, for the first time, explored what […]
