Climate Change - Myth
or Real?
by Fred Pearce, New Scientist
Climate change is with us. A decade ago, it was
conjecture. Now the future is unfolding before our eyes. Canada's Inuit
see it in disappearing Arctic ice and permafrost. The shantytown
dwellers of Latin America and Southern Asia see it in lethal storms and
floods. Europeans see it in disappearing glaciers, forest fires and
fatal heat waves.
Scientists see it in tree rings, ancient coral and bubbles trapped in
ice cores. These reveal that the world has not been as warm as it is now
for a millennium or more. The three warmest years on record have all
occurred since 1998; 19 of the warmest 20 since 1980. And Earth has
probably never warmed as fast as in the past 30 years - a period when
natural influences on global temperatures, such as solar cycles and
volcanoes should have cooled us down. Studies of the thermal inertia of
the oceans suggest that there is more warming in the pipeline.
Climatologists reporting for the UN Intergovernmental Panel on Climate
Change (IPCC) say we are seeing global warming caused by human
activities and there are growing fears of feedbacks that will accelerate
this warming.
