UN panel finds 'unequivocal' evidence for global warming

Paris - Human activity is unequivocably driving climate change and unless it
is modified, it will cause temperatures to rise by as much as 6.4 degrees
Celsius by the end of the century, the Intergovernmental Panel on Climate
Change (IPCC) said in a report issued Friday in Paris.

'Warming of the climate system is unequivocal, as is now evident from
observations of increases in global average air and ocean temperatures,
widespread melting of snow and ice, and rising global mean sea levels,' the
United Nations-overseen IPCC said in a summary of the lengthy report,

The report, entitled Climate Change 2007, also known as the Fourth
Assessment Report (AR4), was made public after a four-day meeting of ICPP
scientists in the French capital.

Eleven of the past 12 years (1995-2006) rank among the warmest years on
record of global temperatures, the report noted, and concluded, 'Most of the
observed increase in globally averaged temperatures since the mid-20th
century is very likely due to the observed increase in anthropogenic
greenhouse gas concentrations.'

The report continued, 'Global atmospheric concentrations of carbon dioxide,
methane and nitrous oxide have increased markedly as a result of human
activities since 1750 and now far exceed pre- industrial values.'

The increase in carbon dioxide in the atmosphere are primarily due to the
use of fossil fuels, the report said, while those of methane and nitrous
oxide were primarily due to agriculture.

'Continued greenhouse gas emissions at or above current rates would cause
further warming and induce many changes in the global climate system during
the 21st century that would very likely be larger than those observed during
the 20th century,' the report continued.

According to several estimates, these changes will raise global temperatures
by an average of 1.1 to 6.4 degrees, depending on the scenario used by the
scientists.

As a result or rising temperatures, glaciers and snow cover have decreased
in both hemispheres, with glacier and ice-cap melt leading to a rise in sea
levels, the report said.

In addition, 'Numerous long-term changes in climate have been observed,' the
IPCC noted.

These include changes in Arctic temperatures and ice, precipitation amounts,
ocean salinity, wind patterns and aspects of extreme weather, including
droughts and the intensity of tropical cyclones.

Arctic temperatures increased at almost twice the global average rate in the
past 100 years, the report said, while satellite data since 1978 reveal that
the extent of the Arctic sea ice has shrunk by 2.7 per cent per decade on
the average.

According to Achim Steiner, executive director of the United Nations
Environment Programme (UNEP), as a result of the report, 'February 2, 2007
will be remembered as the date when the question mark was removed from the
question, if human activity had anything to do with climate change.'

Steiner told reporters in Paris that the report must produce the 'shift from
doubting to having to act ... Science is now unequivocal, but it is looking
for an unequivocal commitment from policy-makers.'

Calling the ICPP report 'an extraordinary scientific consensus that climate
change is already upon us, and that human activities are its cause,' the
World Wide Fund For Nature (WWF) demanded, 'Governments must negotiate
deeper emission cuts for carbon dioxide and other greenhouse gases.'

The IPCC report was produced by some 600 authors from 40 countries. More
than 620 expert reviewers and a large number of government reviewers also
participated.

<snip banalities by Guy Verhofstadt>
The Flemish green opposition party Groen! believes the UN report is
the umpteenth proof that mankind is responsible for the warming of the
earth.

A spokesman for the party accused the 'purple' government (i.e.
consisting of liberal and socialist politicians) of pursuing a shallow
policy with nothing to show for it.

Groen! further lamented the fact that there still isn't a wind farm in
the North Sea and said it is still close to impossible to take in bio
diesel in our country.
