Blame diseases on climate change

Barcelona - A "deadly dozen"
diseases ranging from avian flu to yellow fever are likely to
spread more because of climate change, the Wildlife Conservation Society said on Tuesday.
The society, based in the Bronx Zoo in the United States and
which works in 60 nations, urged better monitoring of wildlife
health to help give an early warning of how pathogens might
spread with global warming.
It listed the "deadly dozen" as avian flu, tick-borne
babesia, cholera, ebola, parasites, plague, lyme disease, red
tides of algal blooms, Rift Valley fever, sleeping sickness,
tuberculosis and yellow fever.
"Even minor disturbances can have far reaching consequences
on what diseases (wild animals) might encounter and transmit as
climate changes," said Steven Sanderson, head of the society.
"The term 'climate change' conjures images of melting ice
caps and rising sea levels that threaten coastal cities and
nations, but just as important is how increasing temperatures
and fluctuating precipitation levels will change the
distribution of dangerous pathogens," he said.
Predicting trouble spots
"Monitoring wildlife health will help us predict where those
trouble spots will occur and plan how to prepare," he said in a
statement.
The UN Climate Panel says that greenhouse gas emissions,
mainly from human use of fossil fuels, are raising temperatures
and will disrupt rainfall patterns and have impacts ranging from
heatwaves to melting glaciers.
"For thousands of years people have known of a relationship
between health and climate," William Karesh of the society told
a news conference in Barcelona to launch the report at an
International Union for Conservation of Nature congress.
Among phrases, people said they were "under the weather"
when ill, he noted.
He said that the report was not an exhaustive list but an
illustration of the range of infectious diseases that may
threaten humans and animals.
