Spotlight on Lake Tahoe: Climate change brings earlier springs and less snow for famous ski resort

This is the first installment of a new, regular series in The Hot Zone that spotlights the local effects of climate change in different places in the world. As the globe heats up, it’s becoming apparent that the effects are not uniform everywhere. Some places are getting wetter, some places drier, species are shifting in different ways with dramatic implications for ecosystems. The predominating force shaping the future of the local environment differs as well. In the oceans, acidification... [Read more]

Climate change could bring a more toxic world

There’s been growing concern about the levels of mercury and chemicals finding their way to the Arctic, which is ending up in the fat of large mammals. Part of the problem is due to the way toxins travel around the globe, but also because animals like polar bears and Arctic foxes are getting leaner. As the extra fat burns away, toxins are released into the blood streams of these animals. Climate change could be exacerbating the problem for very different reasons. Nature News reports that environmental... [Read more]

Californians turned down a proposition on the ballot that would have stripped away the state’s climate change legislation, which is the most robust and influential in the nation, not least because it impacts a state whose economy rivals that of France. The Global Warming Solutions Act (AB 32) was... [Read more]

Earth’s climate could take 100,000 years to recover, and a game to solve our climate woes

Maybe this isn’t news. But it sure got my attention. The Geological Society of London put out a position statement on climate change this week, and among its many interesting tidbits said that the Earth’s climate could take 100,000 years or longer to recover from this most recent bout of CO2, absent any human mitigation. The Society based this projection on numerical models of the climate system that went into the 2007 IPCC report. The Society’s advice, based on this conclusion,... [Read more]
