The Impact of global warming

Description

Earth's temperature is on the rise-and so are incidents of severe weather and heat-related health problems. This program travels the world to observe how global warming, accelerated and exacerbated by air pollution, is affecting society. Coastal erosion in Florida, the destruction of Alaskan forests by the spruce beetle, the depletion of Montana's glaciers, the decline in North Pacific salmon, rising sea levels that threaten to engulf the world's small islands, increases in smog-related asthma, and the spread of malaria into the highlands of Africa, Madagascar, Pakistan, and Peru are all being chalked up to significant changes in ocean and air temperatures.
