Health and climate scientists have mapped how climate change affects different parts of the world in different ways. The scientists point to the fact that changes in the past thirty years may, have been affecting human health. Possible effects include more deaths from extreme(极度的) heat or cold, more storms and more crop failures in dry periods.
The health and climate scientists recently estimated(估计) that climate changes caused by human activity lead to more than one hundred and fifty thousand deaths each year. Cases of sickness are estimated at five million. And the W.H.O. says the numbers could rise quickly by the year of 2003.
Jonathan Patz of an environmental institute led the study. Professor Patz points out that climate scientists connected global warming with the heat that killed thousands in Europe in August, 2003. But he says poor countries least responsible(对……负责) for the warming are most in danger from the health effects of higher temperatures.
Professor Patz says areas in greatest danger include southern and eastern Africa and coastlines along the Pacific and Indian oceans. Also, large cities experience what scientists call a "heat island"effect that can make conditions worse.
Representatives(代表) from about two hundred countries hold a meeting in Canada, to discuss climate change. The ten-day meeting ends on December 9th. It is the first such United Nations meeting since the Kyoto Protocol(京都议定书) took effect earlier this year. The agreement aims to reduce the amount of carbon dioxide(二氧化碳) and other heat-trapping(吸热的) gases sent off into the air.
