A warmer world is going to be a sicker world for everything

from trees to marine life to people, according to a new report by a

panel of U.S. scientists. But opponents remain unconvincing there is 【S1】__

sufficient evidence to support the conclusion.

A team of researchers led by Drew Harvell at Cornell University

have completed a two-year study into climate-disease links. "That is 【S2】__

most surprising is the fact that cli mate sensitive outbreak are 【S3】__

happening with so many different types of pathogens—viruses,

bacteria and parasites (寄生虫)—as well in such a wide 【S4】__

range of hosts including corals (珊瑚虫), oysters, land plants

and birds," Harvell says.

the Co-researcher Richard Ostfeld, an animal ecologist at

Institute of Ecosystem Studies, adds, "This isn't just a

question of coral bleaching for a few marine ecologists, or just 【S5】__

a question of malaria (疟疾) for a few healthy officials—the

number of similar increases in disease incidence is astonishing.

We don't want to be alarmist, but we are alarmed."

The U.S. team found evidence for a variety of routes

for climate warming to adverse affect disease spread, For 【S6】__

instance, warmer winters could reduce seasonal die-off many

pathogens and their carders, or allow them to move into areas

what were previously too cold.

The researchers examined a number of human diseases 【S7】__

which spread researchers have connected to warming, including 【S8】__

malaria, Lyme disease, yellow fever and others. Most involved

in the expanded range of carriers into higher latitudes. The 【S9】__

authors concede that such connections are controversial because

countless factors except climate, such as economics and failed 【S10】__

Prevention measures, play roles in the spread of human diseases.
