Clouds don’t act as a climate thermostat, and they’re not going to save us from global warming

Climate deniers have come up with a lot of arguments about why we shouldn’t worry about global warming – about 200 of them – but most are quite poor, contradictory, and easily debunked by consulting the peer-reviewed scientific literature. The cleverest climate contrarians settle on the least implausible argument – that equilibrium climate sensitivity (ECS – how much a doubling of the amount of carbon dioxide in the atmosphere will increase Earth’s surface temperature) is low, meaning that the planet will warm relatively slowly in response to human carbon pollution.

But they have to explain how that can be the case, because there are a lot of factors that amplify global warming. For example, a warmer atmosphere holds more water vapor, which is itself a greenhouse gas, adding further warming. Warming also melts ice, leaving Earth’s surface less reflective, absorbing more sunlight. There are a number of these amplifying ‘feedbacks,’ but few that would act to significantly slow global warming.

Exclusive: pension schemes will be free to dump fossil fuel investments after government drops ‘best returns’ legal rules

The government is to allow Britain’s £2tn workplace pension schemes to dump their shares in oil, gas and coal companies more easily, empowering them to take investment decisions to fight climate change.

Until now, pension schemes have been hamstrung by “fiduciary duties” that effectively require schemes to seek the best returns irrespective of the threat of climate change. Many have rebuffed calls by members for fossil fuel divestment, citing legal obligations.

Newby Head, Yorkshire Dales When heavy snow blocks the roads, farmer Rodney Beresford goes out to clear the way

Tiny snow devil vortices dance across the scene outside Newby Head Farm, 1,400ft high in Yorkshire’s Three Peaks region. But the snow that tinsels the windbreak of Douglas firs does not stir. Neither does the mound of pink rock salt by the roadside; it is already half-frozen. Sheep farmer Rodney Beresford has to dig hard as he fills the hopper behind his 150hp Deutz tractor.

Decision to end Downer EDI agreement follows Palaszczuk government’s blocking of federal loan for the Queensland project

18 December 1917 Their greens may be dark or even dingy, but when the rains sweep over or the snow melts upon them they shine as if polished

The sombre firs standing black against the leaden sky and the snow-sprinkled ground, the ivy clinging to the ancient bole, the big-leaved laurels and rhododendrons, and the hardy wayside hollies save the country from the monotony of leafless winter. Their greens may be dark or even dingy compared with those of spring, but they are really greens; when the rains sweep over, as they did yesterday, or the snow melts upon them they shine as if polished. The red berries are all the redder for the wet, and even the withered grass is invigorated by the showers which make us shiver.

Unclean air and run-off from agricultural fertilisers alter habitats while competitors threaten to overwhelm sensitive species

Nitrogen pollution in the air is devastating for many sensitive wild plants, which is why so much of the countryside is becoming a vast carpet of nettles, hogweed, hemlock and other rampant vegetation that feasts on nitrogen. In many places, these are running out of control.

Much has been written about the damage to human health from nitrogen oxides given off by traffic, but the damage to sensitive plants has gone largely unnoticed. Excessive nitrogen also comes from ammonia from fertilisers and manures, with much of the countryside awash with nitrates running off farmland.

Environmental Protection Agency chief Scott Pruitt has scrapped an Obama-era rule requiring mining operations to prove they can clean up future pollution

When the Zortman Landusky gold and silver mine, located upstream from Montana’s enormous Fort Belknap reservation, went bankrupt in 1998, the cost of the cleanup fell on the US taxpayer. The costs keep growing.

“Toxic pollution from the Zortman Landusky mine has contaminated nearly a dozen streams in the Little Rocky mountains and harmed the Assiniboine and Gros Ventre tribes that live downstream,” Bonnie Gestring, a staffer with Earthworks, a member of the Western Mining Action Network, said.
