Muller concludes that humans are behind climate change.

Physicist Richard A. Muller was in the news last year after his Koch-funded study of global climate change concluded that it’s real, surely to the Koch brothers’ dismay. Now he’s penned an op-ed for the New York Times in which he says that his ongoing research has led him to the same conclusion as 99.9% […]

Finally, a link has been shown between pesticides and colony collapse disorder.

It’s been hypothesized that pesticides are the source of the global collapse of bee populations, but there had been no controlled experiments demonstrating correlation. A French government group performed just such an experiment and found that, indeed, colonies exposed to low levels of imidacloprid (a common, Bayer-developed insecticide) failed to thrive. They were 100–200% more […]

Clouds are getting lower.

Here’s something I never thought to wonder about: the average height of clouds. From March 2000–February 2010, clouds got 100–130 feet lower. There’s no long-term monitoring, so it’s not clear whether this is part of a larger trend. One theory is that this might be part of a negative feedback loop as the planet responds […]

BBC News: CO2 climate sensitivity ‘overestimated’Of all that is very clearly known about global climate change, the one connection that is not well understood is the quantity of climate forcing that results from each unit of CO2. That is, exactly how much additional heat can the atmosphere store for each each ton of CO2 that […]

Science News: Columbus Blamed For Little Ice AgeHere's a fun theory of the origin of the Little Ice Age, lasting from around 1550–1850: that massive losses of New World population, as a result of disease spread by explorers, resulted in reforestation of huge swaths of the Americas, removing billions of tons of CO2 from the […]
