Booklets and Information
Joel has have some greenhouse booklets "A home guide to reducing energy
costs and greenhouse gases". This has practical information about what you can
do to limit climate change. If anyone would like to borrow the info, please
contact Joel 66847002.
Why is action to prevent or limit climate change important ? Many natural ecosystems are threatened by climate change, including our barrier reef.
Below is a link to news release about likely damage to the barrier reef from El Nino and climate change. http://www.newscientist.com/news/news.jsp?id=ns99992164
Some extracts follow :-
Thomas Goreau, president of the Global Coral Reef Alliance in Chappaqua, New York, and an adviser to the UN Environment Programme says he has received reports in recent days of bleached, dead coral across much of the South Pacific, including Tahiti, the Cook Islands, New Caledonia and Fiji.
"It will take a long time before we have full confirmation of the magnitude of the disaster," he said. "But when it is all in, I predict we will have confirmation that almost all corals across the entire South Pacific have died in the last few months."
The bleaching follows record sea temperatures since the beginning of the year. "Almost all the Great Barrier Reef was 2°C or more above normal for more than two months from early January to mid-March,"says Goreau. "This was hotter and longer than the bleaching that wiped out the Maldives, Seychelles and western Australian reefs in 1998."
The high temperatures appear to be connected to the likely onset of a new El Niņo, which also caused the bleaching in 1998.
But Goreau says global warming is a key underlying factor. "It means reefs are already under stress before El Niņo start," he said.
Donne told New Scientist that "there has been little
mortality of corals yet". But Goreau says: "Catastrophic mortality will
certainly have taken place."
