Eight record-warm months and counting in 2015 so far.
Greenhouse gas cuts must start right away and continue after 2030
The deal currently on the table at the upcoming Paris climate talks would be a big step toward limiting global warming at or near 2 degrees Celsius — deemed a critical environmental threshold by climate scientists.
But reaching that target will require additional commitments to cut greenhouse gas emissions beyond 2025, according to a new study that took a close look at the pledges made by individual countries to reduce their emissions. Continue reading

Traces of medicine in freshwater streams have a wide range of impacts on fish.
New study documents wide range of impacts
Fish exposed to remnant traces of medicines, including pain relievers, muscle relaxants and antidepressants, grow more slowly and have a harder time escaping predators, say scientists who carefully studied the effects of pharmaceutical pollutants.
The study analyzed effects from nine individual pharmaceuticals, as well as varying mixtures of these chemicals, on both juvenile and adult fathead minnows. It was conducted by the Aquatic Toxicology Laboratory at St. Cloud State University and the U.S. Geological Survey, with the findings published in a special edition of Environmental Toxicology & Chemistry.

There is no ‘pause’ in global warming.
‘Why has so much research been framed around the concept of a ‘hiatus’ when it does not exist?’
After a couple of years of furor over the faux global warming pause, scientists with the University of Bristol (UK) say they have yet more evidence there was never any slowdown in the steady rise of temperatures worldwide. Continue reading

There’s no question global temperatures have been climbing steadily for decades, yet a small cadre of radical organizations has been working to deceive the public about the realities of climate change.
New Yale study shows funding behind the effort to mislead Americans on climate science
By Bob Berwyn
Organizations funded by ExxonMobil and the Koch brothers form the core of a disinformation network that has spawned a vast body of literature that deliberately tries to deceive the public about global warming, according to a new study published in the Proceedings of the National Academy of Science.
The research by Yale University researcher Dr. Justin Farrell closely scoured more than 40,000 texts produced by the climate change counter-movement (164 organizations), finding that organizations with corporate funding were more likely to have written and disseminated texts meant to polarize the climate change issue. Continue reading

Scientists say pro-active mitigation could reduce risk
Marine biologists already know that a number of ocean species are at risk from massive seismic blasting operations used to map oil and gas reserves beneath the ocean floor. A new study by scientists with the University of Exeter warns that seismic surveys may also threaten sea turtles.
The review, published in the journal Biological Conservation, found that compared to marine mammals and fish, turtles are largely ignored in terms of research attention and are often omitted from policy guidelines designed to mitigate the environmental risks of seismic surveys. Continue reading

New code could spur significant climate benefits
The UK wants to beef up protection and restoration of peatlands under a new government-backed code that could slash carbon dioxide emissions by 220 million tons and protect rare wildlife at the same time.
The Peatland Code was unveiled at the World Forum for Natural Capital in Edinburgh on November 23 following a successful two-year trial, which has seen businesses fund peatland restoration projects in southwest England, the Lake District and Wales.
The Code is based on research by academics at Birmingham City University and the University of Leeds which revealed that sustainable business investment could reverse the degradation of peatlands and significantly cut greenhouse gas emissions. Continue reading

Ophidiomyces ophiodiicola, a fungus that is afflicting snakes across the Midwest and Eastern US, shares many traits with Pseudogymnoascus destructans the fungus that causes white-nose syndrome in bats, researchers report. Credit
Spread of snake fungal disease mirrors bat-killing white-nose syndrome
U.S. Geological Survey scientists said they’ve identified the fungus that’s been taking a toll on snake populations in parts of the U.S. and warned that global warming could put more snakes at risk.
The fungal disease killing snakes has some eerie similarities to white-nose syndrome, which has wiped out bat populations across the eastern half of the U.S. The snake and bat pathogens emerged in North America in the mid-2000s. Both are moving from east to west across the United States and into parts of Canada. Continue reading
