The genetic makeup of fish will be crucial in determining whether they will be able to deal with the world’s rapidly warming oceans, researchers have discovered.
Scientists have discovered that certain fish can adjust to higher water temperatures over several generations, but only if they fully utilize aspects of their genetic makeup.Full Story
Aiming to jolt the rest of the world to action, President Barack Obama moved ahead Sunday with even tougher greenhouse gas cuts on American power plants, setting up a certain confrontation in the courts with energy producers and Republican-led states.
In finalizing the unprecedented pollution controls, Obama was installing the core of his ambitious and controversial plan to drastically reduce overall U.S. emissions, as he works to secure a legacy on fighting global warming. Yet it will be up to Obama's successor to implement his plan, which reverberated across the 2016 presidential campaign trail.Full Story
Only aggressive efforts to rein in global warming coupled with a rethinking of the British countryside will save many native species of butterfly, according to a study published Monday.
"Widespread, drought-sensitive butterfly population extinction could occur as early as 2050," scientists reported in the journal Nature Climate Change.Full Story
A plume of orange muck from a large mine waste spill in Colorado has drifted about 55 miles (90 kilometers) downriver and is closing in on New Mexico, prompting communities to take precautions until the sludge passes.
New Mexico Environment Department spokeswoman Susan Majure said Friday that the contaminated water is about (10 kilometers) 6 miles from the state line.Full Story
A recent study led by Georgina Mace, ecosystem professor at University College London, indicated that governments across the world have failed to grasp the risk that population booms in coastal cities pose as climate change continues to cause rises in sea levels and extreme weather events. Mace is director of the UCL Centre for Biodiversity and Environment Research.
Mace says population growth in coastal areas can lead to big increases in exposure to extreme weather. The biggest direct effect of projected climate change is heat waves. The number of people dying from extreme heat could increase twelvefold by the end of this century, as a result of global warming combined with increasing numbers living in affected areas.Full Story
The discovery of a genetically distinct group of eastern grey kangaroos sheds light on how they survived aeons of climate-induced expansion and contraction of their grassland habitat, say researchers.
The population, unique to the Sunshine Coast in Queensland, formed as a result of a larger population becoming fragmented due to climate-induced changes in vegetation, they report in a recent issue of PLOS ONE.Full Story
The balance of various plankton species will radically change as the world’s oceans increase in acidity over the next 85 years, according to a new study released this week.
By 2100, ocean acidification will have grown to such an extent that some species of phytoplankton “will die out, while others will flourish,” according to a report by the Massachusetts Institute of Technology, where experts teamed up with the University of Alabama to conduct the study.Full Story
An Australian court Wednesday revoked approval for an Indian-backed project to build what could be one of the world's biggest coal mines, which environmentalists say threatens the World Heritage-listed Great Barrier Reef.
But while environment groups hailed the decision as another important step in the Aus$16.5 billion (U.S.$12.2 billion) project's eventual demise, Indian firm Adani insisted it would go ahead.Full Story
Stranded jellyfish are common sights along beaches around the world. Some places can see up to a billion animals coating the sand. But beachgoers along the U.S. East Coast are running across a surprising sight this summer: thousands of knuckle-size, gelatinous blobs washing up from the surf.
Often called "jellyfish eggs" for their superficial resemblance, these creatures are called salps and they're more closely related to people than they are to jellyfish.Full Story
It has been widely discussed — but not yet peer reviewed. Now, though, you can at least read it for yourself and see what you think.
A lengthy, ambitious, and already contested paper by longtime NASA climate scientist James Hansen and 16 colleagues appeared online Thursday in Atmospheric Chemistry and Physics Discussion, an open-access journal published by the European Geosciences Union. The paper, entitled “Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 ◦C global warming is highly dangerous” is now open for comment — peer review in this journal happens in public.Full Story
