ROBINSON: Is it hot enough to talk climate change?

  • (MIKE SMITH / Las Vegas Sun)

All right, now can we talk about climate change? After a year when the lower 48 states suffered the warmest temperatures, and the second-craziest weather, since record-keeping began?

Apparently not. The climate change denialists — especially those who manipulate the data in transparently bogus ways to claim that warming has halted or even reversed course — have been silent, as one might expect.

Sensible people accept the fact of warming, but many doubt that our dysfunctional political system can respond in any meaningful way.

The thing is, though, that climate change has already put itself on the agenda — not the cause, but the effects. We’re dealing with human-induced warming of the atmosphere. It’s just that we’re doing so in a manner that is reactive, expensive and ultimately ineffectual.

Congress is being asked to approve $60 billion in emergency aid for the states that were ravaged by Hurricane Sandy. Strictly speaking, it is not possible to say this freakish storm was caused by climate change. But Sandy was the second hurricane to strike the northeastern United States in two years — which, to say the least, exceeds the normal frequency of such events.

And Sandy was part of a pattern. According to the National Oceanic and Atmospheric Administration, 2012 was “the second most extreme year on record,” with 11 weather-related disasters including Hurricanes Sandy and Isaac as well as swarms of killer tornados across the Great Plains and the Ohio Valley.

The year was also exceptionally dry; by July, about 61 percent of the country was experiencing conditions that qualify as “drought.” On a cheery note, the situation was not as bad as the Dust Bowl droughts of the 1930s. Less happily, the lack of rainfall in 2012 exacerbated wildfire activity. “The Waldo Canyon fire near Colorado Springs, Colo., destroyed nearly 350 homes and was the most destructive fire on record for the state,” NOAA reported.
