2007 seen as second warmest year as climate shifts


2007 seen as second warmest year as climate shifts
By Alister Doyle, Environment Correspondent2 hours, 11 minutes ago

This year is on track to be the second warmest since records began in the
1860s and floods in Pakistan or a heatwave in Greece may herald worse
disruptions in store from global warming, experts said on Friday.

"2007 is looking as though it will be the second warmest behind 1998," said
Phil Jones, head of the Climatic Research Unit at Britain's University of
East Anglia, which provides data to the U.N.'s International Meteorological
Organization.

"It isn't far behind ... it could change, but at the moment this looks
unlikely," he told Reuters, based on temperature records up to the end of
April.

Jones had predicted late last year that 2007 could surpass 1998 as the
warmest year on record due to rising concentrations of greenhouse gases
emitted mainly by burning fossil fuels and an El Nino warming of the
Pacific.

Almost all climate experts say that the trend is towards more droughts,
floods, heatwaves and more powerful storms. But they say that individual
extreme events are not normally a sign of global warming because weather is,
by its nature, chaotic.

"Severe events are going to be more frequent," said Salvano Briceno,
director of the Geneva-based secretariat of the U.N. International Strategy
for Disaster Reduction.

The 10 warmest years in the past 150 years have all been since 1990. Last
year ranked number six according to the IMO. NASA, which uses slightly
different data, places 2005 as warmest ahead of 1998.

STORMS

Among extreme events, more than 500 people have died in storms and floods in
Pakistan, Afghanistan and India in the past week.

Temperatures in Greece reached 46 C (114.80F) this week as part of a
heatwave across parts of southern Europe. Parts of China have also had a
heat wave in recent days.

And torrential rains have battered northern England and parts of Texas,
where Austin has had its wettest year on record so far.

The U.N. climate panel, drawing on the work of 2,500 scientists, said this
year that it was "very likely" that human activities led by use of fossil
fuels were the main cause of a warming in the past half-century.

It gave a "best estimate" that temperatures will rise 1.8-4.0 Celsius (3.2
and 7.8 Fahrenheit) this century.

Briceno told Reuters that the world had to work out better policies to
prepare for disasters, saying that climate change was adding to already
increasing risks faced by a rising human population of about 6.6 billion
people.

Irrespective of warming, many people were cramming into cities, for
instance, settling in plains where there was already a risk of floods or
moving to regions vulnerable to droughts.

"We need to reduce all the underlying risk factors, such as by locating
communities out of hazard-prone areas," he said. "We now have a clearer
picture of what is going to happen and it's urgent that governments give
this higher priority."

In Germany, average temperatures for the 12 months to May 2007 smashed
records for the past century, raising questions about whether climate change
was quickening, the Potsdam Institute for Climate Impact Research said.

"If this trend continues in the near future, we will be experiencing an
acceleration of global warming in Germany so far unexpected by climate
scientists," it said in a statement.
