Breaking the silence about Spring

Filed under: — eric @ 11 April 2009

Did you know that in 1965 the U.S. Department of Agriculture planted a particular variety of lilac in more than seventy locations around the U.S. Northeast, to detect the onset of spring — in turn to be used to determine the appropriate timing of corn planting and the like? The records the USDA have kept show that those same lilacs are blooming as much as two weeks earlier than they did in 1965. April has, in a very real sense, become May. This is one of the interesting facts that you’ll read about in Amy Seidl’s book, Early Spring, a hot-off-the-press essay about the impacts of climate change on the world immediately around us – the forest, the birds, the butterflies in our backyards.

Wilkins ice shelf collapse

Filed under: — gavin @ 6 April 2009

Since people are wanting to talk about the latest events on the Antarctic Peninsula, this is a post for that discussion.

The imagery from ESA (animation here) tells the recent story quite clearly – the last sliver of ice between the main Wilkins ice shelf and Charcot Island is currently collapsing in a very interesting way (from a materials science point of view). For some of the history of the collapse, see our previous post. This is the tenth major ice shelf to collapse in recent times.

Maybe we can get some updates and discussion of potential implications from the people working on this in the comments….?

Advocacy vs. Science

Filed under: — gavin @ 1 April 2009

The advocate will pick up any piece of apparently useful data and without doing any analysis, decide that their pet theory perfectly explains any anomaly without consideration of any alternative explanations. Their conclusion is always that their original theory is correct.

The scientist will look at all possibilities and revise their thinking based on a thorough assessment of all issues – data quality, model quality and appropriateness of the the comparison. Their conclusion follows from the analysis whatever it points to.

Which one is which?

Farewell to our Readers

Filed under: — group @ 1 April 2009

We would like to apologize to our loyal readers who have provided us so much support since we first went online in December 2004. However, after listening to the compelling arguments of the distinguished speakers who participated in the Heartland Institute’s recent global warming contrarian conference, we have decided that the science is settled — in favor of the contrarians. Indeed, even IPCC chair Rajendra Pachauri has now admitted that anthropogenic climate change was a massive hoax after all. Accordingly, RealClimate no longer has a reason for existence. The contrarians have made a convincing case that (a) global warming isn’t happening, (b) even if it is, its entirely natural and within the bounds of natural variability, (c) well, even if its not natural, it is modest in nature and not a threat, (d) even if anthropogenic warming should turn out to be pronounced as projected, it will sure be good for us, leading to abundant crops and a healthy environment, and (e) well, it might actually be really bad, but hey, its unstoppable anyway. (Can we get our check now?)
