Sierra Nevada Heating Up; Muir’s Glacier Gone

  By

The Sacramento Bee is starting a major new series coodinated by
veteran writer Tom Knudson on the effects of global warming on the
Sierras.  They are putting very serious resources into this (and
getting a flood of naysayer comments, which sound more and more
pathetic but are a reminder of where a significant portion of the
public still are on the issue).  There is a multi-part series coming
out in print with today’s article as the first, plus a web log and other
useful resources online at http://www.sacbee.com/sierrawarming/

Britain’s woods and forests face their greatest disruption since the
last Ice Age with native species such as oak, beech and ash under
threat from climate change, according to research.

These and other native trees are likely to retreat from parts of the
warmer south and west as well as East Anglia, leaving woodlands
dominated by species adapted to heat and drought, such as Corsican
pine, Spanish oak and shrubs including spindle and dogwood. Many of
these species were introduced to Britain as ornamental trees but are
now expected to flourish in the wild. American giant redwoods already
grow well in England and could thrive.

.OSLO (Reuters)

A drastic cooling of the climate in western Europe happened exactly 12,679 years ago, apparently after a shift to icy winds over the Atlantic, scientists said on Friday, giving a hint of how abruptly the climate can change.

The study, of pollens, minerals and other matter deposited in annual layers at the bottom of Lake Meerfelder Maar in Germany, pinpointed an abrupt change in sediments consistent with a sudden chill over just one year.
