It's too early to state categorically that China is
experiencing another "warm winter" this year, but the world's
fourth largest economy is definitely suffering the impact of global
warming, a senior meteorological official said on Tuesday.
Qin Dahe, director of the China Meteorological
Administration, told a press conference in Beijing that global
warming had made extreme weather -- such as high temperatures,
drought and hurricanes -- more common in China.
Beijing temperatures reached
10.8 degrees Celsius on Sunday, the first day of spring according
to China's traditional lunar calendar, and surged to 16 on Monday,
the highest temperature at this time of year for the past 167
years.
Yulan Magnolia trees on Chang'an Avenue in downtown
Beijing -- which normally blossom in late March -- are already in
bud.
High temperatures in Beijing this winter are
"obviously" related to global warming but the final verdict on the
city's "warm winter" will only be given at the end of February, Qin
said.
Beijing has had 20 "warm
winters"-- where average December to February temperatures are at
least 0.5 degrees Celsius higher than the average-- in a row since
1986.
This year, signs of a warm winter have not been
limited to Beijing. In Nanjing, capital of east China's Jiangsu Province, sweet-scented osmanthus is
already in blossom.
In the northeast, the average January temperature is
up 4.1 degrees Celsius on normal years and up 2.7 degrees in the
southwestern Qinghai-Tibet Plateau.
Citing the latest report of the intergovernmental
panel on climate change (IPCC), Qin said that if a temperature
increase of 1.9 to 4.6 degrees was sustained for a millennium, the
Greenland ice sheet would melt completely and result in a sea-level
rise of 7 meters.
Qin, who co-chairs IPCC working group I, said that,
under the influence of human activities, the global climate had
been warming since 1750, as evidenced by higher average air and
ocean temperatures, the widespread melting of snow and ice and
rising sea levels.
Last summer's severe drought around Chongqing
Municipality in southwestern China and typhoon attacks in east
coast both occurred against a background of global warming, he
said.
Qin said that meteorological disasters caused direct
economic losses of 200 to 300 billion yuan (US$25 billion to
US$37.5 billion) in China annually, which was equivalent to two to
five percent of China's gross domestic product.
Greenhouse gas emissions, and carbon dioxide
discharges in particular, are widely considered to be the prime
factor in global warming. China, the world's second largest
greenhouse gas emitter after the United States, may have to face
the challenge of declining grain output and increasingly scarce
water resources.
The government has backed the UN-brokered Kyoto
treaty, and committed itself to improving its energy efficiency by
setting the goal of cutting its energy consumption by 20 percent
per unit of GDP in the period from 2006 to 2010, Qin
noted.
China reduced emissions by
some 800 million tons of coal equivalent from 1991 to 2005. The
country's forests, grasslands and natural reserves have helped
absorb another 3.06 billion tons, he said.
