This is now strictly a science blog. I have moved all bird-related content over to http://swiftbirder.tumblr.com/. Please check it out.

I just stumbled on this new blog over at realclimate.org called the “Madden-Julian Conversation”. They have a series of very nice tutorial posts speaking about atmospheric modes of variability, including large-scale patterns such as the El Niño-Southern Oscillation (ENSO), the Indian Monsson and the Madden-Julian Oscillation (MJO). It is an excellent introduction to understanding the regularity and chaos of our changing climate.
What is the MJO? Part 3 - on modes of variability, and space and time scales
What is the MJO? Part 4 - more background on modes of variability
What is the MJO? Part 5 - interannual and intraseasonal, prediction, beating chaos

Canada Cuts Ozone Sonde Network -

This is really troubling. Canada, with its huge landmass in the Arctic, has a tremendous responsibility to the global community to continue its long-term monitoring of this fragile region. I don’t think Environment Canada are to blame specifically; they are just trying to cope with significant budgets cuts under the current government.

Reduced emissions of ozone depleting substances will mitigate global warming -
An interesting new study was presented at the American Geophysical Union meeting in San Fransisco in December 2010: It was shown that controlling emissions of chlorofluorocarbons (CFCs) within the Montreal Protocol and its amendments to prevent thinning of the stratospheric ozone layer, will have significant beneficial side-effects on climate change. It is projected that global warming could be reduced by as much as 1.5 degrees by 2070, compared to a scenario in which CFCs would have been allowed to increase unabated.
