With these new consumption estimates, the researchers calculated that the early 20th-century abundance of krill in the Southern Ocean had to be about five times what it is now in order to feed the pre-whaling whale population. This implies a complex role for whales in their ecosystems where the decline or recovery of their populations is strongly tied to overall ecosystem productivity and functioning.
This is all because of toxic smog across much of northern India. It happens every winter as industrial and vehicular emissions mix with smoke from crop-burning after the harvest.
The line calling for the "phase-down of unabated coal" and an end to "inefficient" fossil fuel subsidies is unprecedented in a COP agreement, experts say, even if it was weakened.
The previously undiscovered signal, now known as an “anti-predator pipe, shares acoustic traits with alarm shrieks, fear screams and panic calls of primates, birds and meerkats,” according to the study.
It’s the governmental and capitalist systems that have made life on the planet untenable. It’s abhorrent that the burden of environmental collapse falls first on the shoulders of young people and the global south, when oil corporations and countries like the United States carry an outsized responsibility for the crisis.
"It’s a threat multiplier that amplifies and accelerates existing inequities," she said during "gender day" at the summit, according to the New York Times. "Eighty percent of people displaced by climate change globally are women." The United Nations, which organized the summit, said women are more vulnerable to climate change due to social, economic and cultural factors.
A vast stretch of the Yamuna river is covered with white toxic foam, caused in part by pollutants discharged from industries ringing New Delhi. Still, on Wednesday, hundreds of Hindu devotees stood knee-deep in its frothy, noxious waters, sometimes even immersing themselves for a customary dip to mark the festival of Chhath Puja.
Predicting faster sea level rises and more frequent and extreme storms due to global warming, the government said it could only afford to keep defending the village for another 40 years. Officials said that by 2054, it would no longer by safe or sustainable to live in Fairbourne. Authorities therefore have been working with villagers on the process of so-called “managed realignment” -- essentially, to move them away and abandon the village to the encroaching sea.
Twenty-four countries and a group of leading car manufacturers have committed to ending the era of fossil-fuel powered vehicles by 2040 “or earlier”, in a major new commitment set at Cop26.
Industrial chicken, pork and dairy production, Holden argues, are only possible because of environmentally unsustainable grain monocultures; stop these and cheap, polluting meat production would end.
Flint managers appointed by then-Gov. Rick Snyder and regulators in his administration allowed the city to use the Flint River in 2014-15 without treating the water to reduce corrosion. As a result, lead in old pipes broke off and flowed.
