Global Warming Puts 1/3 Species At Risk

From those hard-boiled scientists at the BBC:


Warming ‘already changing world’

By Richard Black

Thursday, 5 April 2007

Climate change is already having major impacts on the natural world, a UN report is set to announce.

The Intergovernmental Panel on Climate Change (IPCC) believes there is also a discernible, though less marked, impact on human societies.

The IPCC is due to release the summary of its report on Friday, and talks look set to go on until the last minute.

Draft versions seen by BBC News 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 last-minute wrangling is likely to affect the degree of certainty in the final version, but not the overall direction.

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

Fresh water is perhaps the most serious issue for human societies.

The world’s great mountain ranges, such as the Himalayas, Rockies, Andes and Alps, act as natural reservoirs, trapping winter rain and snowfall as ice, and releasing it gradually in the summer.

Evidence suggests that glaciers are shrinking in all of these ranges. One recent study predicted that 75% of Alpine glaciers would have vanished by the end of this century.

As the ice disappears, spring and autumn floods become more likely, with an increased risk of drought in summer. The IPCC is expected to say there is “very high confidence” that these trends are already occurring.

It will also project a higher risk of flooding for many major cities on or near the coast.

Another significant human impact projected in the drafts is a reduction in agricultural output for most regions of the world.

Africa, most of South America, and Asia are likely to see crop yields and livestock productivity falling…

This is mass hysteria at its finest.

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.

The same IPCC claims that the world’s temperature rose about 0.74 °C (1.3 °F) in the last century.

The IPCC now claims global temperatures will increase by 1.5 °C (2.5 °F) between 1990 and 2100. In other words, “global warming” will increase about twice as much in the next 100 years.

But how many species disappeared in the last 100 years because of global warming? How many cities were flooded? Where were there water shortages?

Even if twice as many species disappear because of “global warming,” what is 2 x 0? If twice as many cities are flooded due to higher temperatures than in the last century, that would be how many again?

It is simply laughable that anyone takes this nonsense seriously.
