Arctic sea ice has recovered in extent from previous lows. But that does not tell the whole story. When temperatures are less volatile, sea ice forms in layers over multiple years to a thick and solid mass. Ice that forms under this year’s conditions is likely to be thinner and less stable than what it replaces, more vulnerable to another year’s warming and less effective as a temperature regulator. For these reasons, the current drastic melting of the Arctic cannot be regarded merely as an outlier. While the effects of an ice-free Arctic on global weather systems are still in the realm of known unknowns, it is a known known that they will be disruptive. The current Arctic temperature and sea ice charts look like the beginning of a whole new trend, one that could change the global climate system for ever. … [Read more...] about The Guardian view on climate change action: don’t delay
Vulnerable countries to climate change
Baroness Anelay of St Johns, minister of state for the Foreign and Commonwealth Office (FCO), said last year: “Climate change is not only a threat to the environment but to global security and economic prosperity. That therefore makes it a top priority not only for environment ministers but foreign ministers too.” … [Read more...] about UK slashes number of Foreign Office climate change staff
“It will be very interesting to see how much the government accepts this view,” said Bob Ward, policy and communications director at the Centre for Climate Change Economics and Policy. “If it does then it will have to outline – within a year – how it intends to protect the nation. New coast defences, flood protection, water supply systems and other measures will be needed, and those won’t be cheap.” … [Read more...] about Government to outline climate change risks facing UK in new report
In addition to snow cannons, an expansion of ski areas into higher altitudes is expected to help defy the effects of climate change. Bätzing sees this as a "catastrophic development". He points to the planned merger of the Tyrolean ski resorts of Pitztal and Ötztal, which would result in massive impacts on the partially untouched glacier landscapes, and calls for "an outright ban on further mergers of ski resorts." And he is not alone in opposing this. The Alpine Associations and the International Commission for the Protection of the Alps Cipra are also calling for such a ban. … [Read more...] about A skiing holiday in times of climate change?
When analysing tracking data, composed of 20 years' worth of tagging birds with satellite tags and following their seasonal migrations, Dr LaPoint noticed an unusual pattern. Younger raptors would shift the timing of their journey, seemingly adapting to weather conditions and climate. … [Read more...] about Golden eagle migration out of sync with climate change
