For any of you global warming denier trolls lurking out there, here you finally have it: ANOTHER final study that undeniably shows a link between manmade greenhouse gas emissions and the warming that has occurred.
Yes, yes, and the sky is blue as well. AND the Earth revolves around the sun. I know most of us don’t need more scientific evidence that putting pollution in the atmosphere fundamentally disrupts the climate, but what is most interesting about this study is it calculates a precise amount of warming per ton of CO2 or equivalent:
Until now, it has been difficult to estimate how much climate will warm in response to a given carbon dioxide emissions scenario because of the complex interactions between human emissions, carbon sinks, atmospheric concentrations and temperature change. Matthews and colleagues show that despite these uncertainties, each emission of carbon dioxide results in the same global temperature increase, regardless of when or over what period of time the emission occurs.
These findings mean that we can now say: if you emit that tonne of carbon dioxide, it will lead to 0.0000000000015 degrees of global temperature change.
If we want to restrict global warming to no more than 2 degrees, we must restrict total carbon emissions — from now until forever — to little more than half a trillion tonnes of carbon, or about as much again as we have emitted since the beginning of the industrial revolution.
The full article will eb published in the June 11 edition of Nature.
And if that wasn’t enough, this from the HuffPo about coal ash:
Just how bad has the coal ash situation gotten in the United States? So bad that the Department of Homeland Security has told Sen. Barbara Boxer (D-Calif.) that her committee can’t publicly disclose the location of coal ash dumps across the country.
The pollution is so toxic, so dangerous, that an enemy of the United States — or a storm or some other disrupting event — could easily cause them to spill out and lay waste to any area nearby.
There are 44 sites deemed by the Environmental Protection Agency to be high hazard, but Boxer said she isn’t allowed to talk about them other than to senators in the states affected. “There is a huge muzzle on me and my staff,” she said.
“Homeland Security and the Army Corps [of Engineers] have decided in the interests of national security they can’t make these sites known,” she said.
There are several hundred coal ash piles across the nation, she said, all of them unregulated.
“If these coal ash piles were to fail they’d pose a threat to the people nearby,” she said. While keeping it from the public, DHS is alerting first responders as to the location of the piles.
“I believe it is essential to let people know,” said Boxer, arguing that if people knew what was in their backyard they’d press public officials to clean it up and protect the area. “I think secrecy might lead to inaction…I am pressing on this.”
Especially in the wake of Kingston fly ash disaster, which was the worst environmental disaster ever in the US– worse even than the Exxon Valdez- this seems pretty simple to me: climate change is caused by greenhouse gases, coal is the major contributor to CO2 emissions, coal ash is so dangerous we can’t even know where the dumps are because of national security… so, let’s stop burning coal? That’s a solution so easy, it’s not surprising anyone in Washington (or for that matter, Austin) hasn’t proposed it. Oh wait, we have. It’s called a coal moratorium, and we should be doing it.
