PARIS (Reuters) - The U.N. climate panel issued its strongest warning
yet on Friday that human activities are heating the planet, putting
extra pressure on governments to do more to combat accelerating global
warming.
The Intergovernmental Panel on Climate Change (IPCC), the most
authoritative group on warming which groups 2,500 scientists from more
than 130 nations, predicted more severe rains, melting glaciers,
droughts and heatwaves and a slow rise in sea levels.
The final text of the report said it was "very likely" -- meaning a
probability of more than 90 percent -- that human activities led by
burning fossil fuels explained most of the warming in the past 50 years.
That is a shift from the last report, in 2001, when the IPCC said the
link was "likely", or at least 66 percent probable.
"Most of the observed increase in globally averaged temperatures since
the mid-20th century is very likely due to the observed increase in
anthropogenic (human) greenhouse gas concentrations," said the text,
seen by Reuters.
The talks among government representatives and IPCC scientists, meeting
in Paris since Monday, ended after midnight after a wrangle over rising
ocean levels. IPCC leaders will formally unveil the results of six
years' work in Paris at 8:30 a.m.
A 20-page summary for policy makers outlines threats such as a melting
of Arctic sea ice in summers by 2100 and a slowing of the Gulf Stream.
U.N. officials hope the report will prompt governments and companies to
do more to cut emissions of greenhouse gases, released mainly by burning
fossil fuels in power plants, factories and cars.
TEMPERATURES WILL RISE
The report also predicted a "best estimate" that temperatures would rise
by between 1.8 and 4.0 Celsius (3.2 and 7.8 Fahrenheit) in the 21st
century with a likely range from 1.1 to 6.4 Celsius.
Temperatures rose 0.7 degrees in the 20th century and the 10 hottest
years since records began in the 1850s have been since 1994. Many
European countries have had their warmest January on record.
"The IPCC's latest report provides the most conclusive evidence to date
that human activities are causing dangerous climate change," said
Camilla Toulmin, head of the International Institute for Environment and
Development, a London-based research group.
"Time is running out to cut greenhouse gas emissions," she said.
"For those who are still trying to determine responsibility for global
warming, this new U.N. report on climate change is a scientific smoking
gun," Democratic Congressman Edward Markey of Massachusetts said.
"We ignore it at the peril of our children and their children," he said.
Thirty-five rich nations have signed the Kyoto Protocol that sets caps
on emissions of greenhouse gases -- but Kyoto's first period runs only
to 2012 and big emitters led by the United States, China and India have
no targets.
President George W. Bush said last week that climate change was a
"serious challenge". He pulled out of Kyoto in 2001, saying Kyoto-style
caps were an economic straitjacket and that it unfairly omitted
developing nations.
Sea levels are likely to rise by between 28 and 43 cm (11-17 inches)
this century, according to an earlier draft of the IPCC report.
The range is lower than forecast in 2001 but delegates said they
clarified that the projection did not include the possibility of an
accelerating melt of Greenland ice, which some studies suggest is under
way.
