China's top science experts reject global warming and carbon scares Tuesday, 06.Dec.2011, 00:24 (GMT+3) CHINA's highest authority on climate change, the Chinese Academy of
Science, has dismissed conventional wisdom on dangers posed by global
warming as well as the harm supposedly done by carbon emissions, reports
Hong Kong's South China Morning Post.
CHINA's highest authority on climate change, the Chinese Academy of
Science, has dismissed conventional wisdom on dangers posed by global
warming as well as the harm supposedly done by carbon emissions, reports

"We are not experiencing the most dramatic climate change in recent
history," said Liu Yu, the academy's Institute of Earth Environment
deputy director. "In northern China, the warmest period occurred from
401-413 AD, which had an annual mean temperature 0.16 degrees Celsius
higher than today's."
Global air, sea and land transport sectors have been faced with huge
expenses to meet rising regulatory compliance costs, some of which are
set in ways to drive smaller operators out of business.
The timing of China's statement, based on a study of Tibetan tree rings,
is also significant because of the current international climate change
talks in Durban, South Africa and China's opposition to carbon taxes
imposed by the European Union on aircraft flying in and out of EU
territory.
Continuing, Prof Liu said: "Popular belief is that industrialisation has
led to the fastest rate of warming witnessed by humans, that we are at
the warmest time of the modern era and that we are causing global
warming by emitting carbon dioxide into the atmosphere. None of that
fits the records in tree rings.
''The climate change debate has more political significance than
scientific. Diplomats can sit at negotiating tables talking about carbon
caps while scientists have not reached an agreement on the role of
carbon dioxide in global warming," he said.
"Political decisions must be based on sound scientific foundation, or
they will be useless, if not dangerous," he told the SCMP in an extended
interview.
Prof Liu has studied untouched forests dating back thousands of years
along the remote Tibetan Plateau to assess current weather patterns and
said that tree rings are key to understanding and predicting climate
change.
For more than a decade, he has run simulations on computers to determine
annual temperatures in the region over the past 2,485 years. Prof Liu
said the sun, and not man-made factors. cause climate changes. "We
believe that the sun and atmospheric circulations play a vital, if not
decisive, role," he said.
