As Hong Kong shivers through its second-longest
cold spell since 1885, scientists point to global warming to explain
the abnormal cold weather phenomenon worldwide.
Unusually cold weather is gripping a number of countries, including China and Canada.
"We
are seeing extremely unusual weather across the world," said polar
researcher Rebecca Lee Lok-sze. "This is due to human activities and
our style of living. Carbon dioxide emissions are heavy, which is
changing the weather rapidly. We could see colder winters and hotter
summers in the future in Hong Kong."
Greenpeace echoed the view, saying mainland
scientists had also concluded that the extreme cold weather in China
was triggered by climate change. "This does not only cause an increase
in global warming but also causes extreme weather patterns," said
campaigner Edward Chan.
