Finding that Global Warming Threatens Over One
Million Species Underscores Urgent Need for Action
WWF US
A new scientific study in Nature predicting over one million species
could die out due to global warming is an urgent message to reduce the
heat-trapping gases emitted by dirty energy sources, according to World
Wildlife Fund. It confirms the findings of previous WWF reports.
The Nature article revealed that human induced climate change could result
in the extinction of more than a million terrestrial species in the next
fifty years.
"Climate change is emerging as the single biggest threat for
wildlife," said Dr. Lara Hansen, chief scientist, WWF Climate
Change Program. "The recent study in the scientific journal Nature
reinforces the urgent need to take immediate action to reduce heat-trapping
gases known to cause climate change."
Practical steps to reduce these emissions are clearly laid out in a WWF
campaign, PowerSwitch! which challenges the power sector to increase energy
efficiency and switch to clean energy sources like wind, solar and biomass.
Heat-trapping carbon dioxide emissions are key culprits in global warming,
and 37 percent of CO2 emissions stem from electric power production, mainly
through the burning of fossil fuels like coal, oil and gas. PowerSwitch!
also calls on power companies and elected officials to support policies
to limit heat-trapping CO2 emissions. WWF has produced detailed scenarios
for the United States, the European Union (with specific reports on Germany
and Italy), the Philippines and Japan to demonstrate how this can be achieved.
"We have to act now to minimize damage to the wildlife and wild
places that we all love," said Dr. Hansen. "With many
clean energy alternatives available, the power sector has the opportunity
to take the lead by implementing responsible solutions rather than continuing
to emit heat-trapping gases."
Although the study published in Nature is probably the most comprehensive
analysis to date on climate change and its impact on species survival,
it echoes the findings of previous WWF reports. The WWF report "Habitats
at Risk," published in February 2002, was the first study to look
specifically at how global warming in the coming decades could impact
our most treasured natural habitats - outstanding areas still rich in
species and biological distinctiveness. It examined 113 land-based regions
of significant size and vegetative surface and found that huge parts of
the world, from the tropics to the poles are at risk.
At the World Parks Congress in September 2003, WWF released a study,
entitled "No Place to Hide," on climate change impacts on protected
areas. The WWF study found that climate change impacts are already being
observed in many parks worldwide, including in the United States, and
that climate change is the most consistent explanation for many alterations
in the range or behavior of animals and plants.
