Good Night Irene

Irene visits my neighborhood

Since I got environmental religion about 10 years ago, I've watched in disbelief as the deniers denied and as most other people didn't think too much about it. Our recent post-Hurricane Irene week without electricity made me start thinking about the climate again. I watched an interesting NOVA show, "Secrets Beneath the Ice." It was a good refresher with new information on advances in the science behind global warming.

I just read an article in Nature with some news about tying climate and weather together in a more accurate manner. That will be useful. Here's an excerpt:

Heavy weather

Severe storms make the public think of climate change. Scientists must work to evaluate the link.

Extreme weather makes news, as was demonstrated last month by the blanket coverage of the devastation caused to the east coast of the United States by Hurricane Irene. But was the prominence of the story a feature of modern media hype in a rolling-news world? Hardly. According to a New York Times analysis, when Hurricane Andrew made landfall in Florida in 1992 and killed 22 people, it received twice the traditional news coverage that Irene did.

What is new is that coverage of extreme weather is now often accompanied by a question: is this a consequence of climate change? This question was raised frequently after Hurricane Katrina smashed through New Orleans in 2005. Most climate scientists responded equivocally, as scientists do: climate is not weather, and although all extreme weather events are now subject to human influence, global warming driven by greenhouse gases cannot be said to 'cause' any specific manifestation of weather in a simple deterministic sense.

Is that response enough? The question, after all, seems fair, given the dire warnings of worsening weather that are offered to the public as reasons to care about global warming. It may irritate some scientists, but in fact the question can be seen as a vindication of their efforts to spread the message that the climate problem is a clear and present danger. Most people associate the climate with the weather that they experience, even if they aren't supposed to. And they are right to wonder how and why that experience can, on occasion, leave their homes in pieces.

Given the growing interest, it is a good sign that scientists plan to launch a coordinated effort to quickly and routinely assess the extent to which extreme weather events should be attributed to climate change (see page 148). The ambitious idea is in the early stages, and its feasibility is yet to be demonstrated. It will require funding, access to climate data from around the world and considerable computer time. Funding agencies and climate centres must provide the necessary support.  [More]

I look forward to reading more about progress on the ability to attribute storms to climate change.
