300 million years ago, the formation of coal almost turned Earth into a snowball – “By burning the coal, the CO2 is again destabilizing the Earth system”

10 October 2017 (PIK) – While burning coal today causes Earth to overheat, about 300 million years ago the formation of that same coal brought our planet close to global glaciation. For the first time, scientists show the massive effect in a study published in the renowned Proceedings of the US Academy of Sciences. When […]

Microbes dictate regime shifts causing anoxia in lakes and seas – “Hysteresis loops and tipping points are a common feature of oxic-anoxic transitions, causing rapid drops in oxygen levels that are not easily reversed”

6 October 2017 (UvA News) – Gradual environmental changes due to eutrophication and global warming can cause a rapid depletion of oxygen levels in lakes and coastal waters. A new study led by professors Jef Huisman and Gerard Muyzer of the University of Amsterdam (UvA) shows that microorganisms play a key role in these disastrous […]

New insights from NASA’s Orbiting Carbon Observatory-2 satellite showcased in Science magazine

  By Carol Rasmussen 12 October 2017 (JPL) – High-resolution satellite data from NASA’s Orbiting Carbon Observatory-2 are revealing the subtle ways that carbon links everything on Earth – the ocean, land, atmosphere, terrestrial ecosystems and human activities. Scientists using the first 2 1/2 years of OCO-2 data have published a special collection of five […]

Geologic evidence of rapid sea level change and superstorms portend ominous prospects for a warming earth – “Our global society is producing a climate system that is racing forward out of humanity’s control”

Philadelphia, PA, 12 October 2017 (Elsevier) – While strong seasonal hurricanes have devastated many of the Caribbean and Bahamian islands this year, geologic studies on several of these islands illustrate that more extreme conditions existed in the past. A new analysis published in Marine Geology shows that the limestone islands of the Bahamas and Bermuda […]

Soil’s contribution to the carbon cycle in a warming world

AMHERST, Massachusetts, 5 October 2017 (UMass Amherst) – Microbiologist Kristen DeAngelis and her graduate student Grace Pold at the University of Massachusetts Amherst, with colleagues at Woods Hole Marine Biological Laboratory (MBL) and in New Hampshire, report results in the Oct. 6 issue of Science from their study of warming-related soil carbon cycling changes in […]

Mathematics predicts a sixth mass extinction

By Jennifer Chu 20 September 2017 (MIT News) – In the past 540 million years, the Earth has endured five mass extinction events, each involving processes that upended the normal cycling of carbon through the atmosphere and oceans. These globally fatal perturbations in carbon each unfolded over thousands to millions of years, and are coincident […]

New climate risk classification created to account for potential “existential” threats – Researchers identify a one-in-20 chance of temperature increase causing catastrophic damage or worse by 2050

14 September 2017 (Scripps) – A new study evaluating models of future climate scenarios has led to the creation of the new risk categories “catastrophic” and “unknown” to characterize the range of threats posed by rapid global warming. Researchers propose that unknown risks imply existential threats to the survival of humanity. These categories describe two […]

Big Oil must pay for climate change. Now we can calculate how much

By Peter C Frumhoff and Myles Allen 7 September 2017 (The Guardian) – As communities in coastal Texas and Louisiana confront the damage wrought by Hurricane Harvey, another hurricane, Irma, fueled by abnormally warm waters, is barreling into the Caribbean and threatening Puerto Rico and Florida.We know that the costs of both hurricanes will be […]

The great nutrient collapse – “We are witnessing the greatest injection of carbohydrates into the biosphere in human history – an injection that dilutes other nutrients in our food supply”

By Helena Bottemiller Evich 13 September 2017 (Politico) – Irakli Loladze is a mathematician by training, but he was in a biology lab when he encountered the puzzle that would change his life. It was in 1998, and Loladze was studying for his Ph.D. at Arizona State University. Against a backdrop of glass containers glowing […]

This weather is not normal. And it will only get worse. “How many more lives must be destroyed by historic hurricanes, floods, and wildfires before the government admits that climate change is a problem?”

By Emily Atkin 7 September 2017 (New Republic) – The days leading up to Hurricane Harvey’s landfall in Texas last week were some of the most nerve-wracking in meteorological history. Forecasters watched helplessly as a true monster storm—one that would eventually become the most extreme rain event in recorded American history—moved toward Houston, the country’s […]
