Pacific Whale decline...

Over fishing or is it something else? "The Whale starving, their fat has just gone, and there's not a lot of breeding going on," Dr Megill related. "They seem to spend their time looking around for food when they should be breeding"

The cause of this change is not clear. A link with climatic conditions makes sense; warmer waters hold less oxygen, they become less productive, resulting in less of the tiny crustaceans which are the grey whales' favoured food. Source: BBC:: Pacific whale decline 'a mystery'

Water Shortages



















The Intergovernmental Panel on Climate Change (IPCC) warn it will be hard for societies to adapt to all the likely climate impacts.

The report is set to say that a temperature rise above 1.5C from 1990 levels would put about one-third of species at risk of extinction.

More than one billion people would be at greater risk of water shortages, primarily because of the melting of mountain glaciers and ice fields which act as natural reservoirs.

The scientific work reviewed by IPCC scientists includes more than 29,000 pieces of data on observed changes in physical and biological aspects of the natural world.

Eighty-five percent of these, it believes, are consistent with a warming world.
