Heat from cities barely affects global warming

One of the many arguments that deniers rely on to pooh-pooh climate change is the prevalence of the “urban heat island” effect, i.e. the tendency for cities to absorb and retain heat. The problem’s not gas-belching cars and factories, it’s all those city-dwelling lefties! But according to a new study from Stanford University, there's just no possible way that cities are causing global warming, at least not on the same scale that greenhouse-gas emissions are.

At most 4 percent of "gross global warming since the Industrial Revolution" can be traced back to urban heat island, the study found. Greenhouse gases are responsible for 79 percent. So, if you live in a city, don't sweat it! If you've commuted for 1.5 hours in a car for the past two decades, maybe sweat it.

The study also contained some bad news about white roofs.

Australians to kill camels for carbon credits

Australians really don't like the hundreds of thousands of feral camels that run around the continent, so every once in a while the government decides to spend money on sending guys with guns up in helicopters to cull their numbers. But now they have a utilitarian justification for the culls: They're fighting climate change.

Like cows, camels spew methane from their digestives systems. By cutting their lives short, one company argues, Australia would be preventing the release of the methane the camels would emit over their remaining years. The company, Northwest Carbon, also says it'll be able to offer carbon credits for the reduction in emissions.

Shark massacre reported off of Colombian coast

Off the coast of Colombia, as many as 2,000 sharks in a wildlife sanctuary have been massacred, says the Colombian government. A team of divers first alerted the government to the killings, according to the Guardian:

[The divers] saw a large number of fishing trawlers entering the zone illegally," [environmental minister Sandra] Bessudo said. The divers counted a total of 10 fishing boats, which all were flying the Costa Rican flag. 

New skimmer can capture nearly 90 percent of spilled oil

After the BP oil spill, the X Prize Foundation offered a $1 million prize to anyone who could come up with a better way of cleaning up oil. But the winning team, Team Elastec/American Marine, didn’t merely do better -- they blew other oil skimmers out of the water (ha). Their skimmer sucks up nearly 90 percent of spilled oil. You can check it out in the video above. The details, according to NPR:
