Higher temperatures would also exacerbate air pollution problems such as ozone. Climate change would affect precipitation resulting in severe droughts in some areas, and floods in others. This in turn would influence crop production in those locations. Ecological zones might shift with many plants and animals needing to find more suitable habitats. If climate change is rapid, many species may be unable to migrate fast enough to survive.
Climate change is an international problem .
In 1979, a group of international scientists concerned about global warming convened the first World Climate Conference. These scientists were instrumental in bringing the issue of global warming to the attention of world leaders. In 1990, the IPCC convened a second World Climate Conference, and issued a report which set forth scientific evidence for the occurrence of global warming. In 1992, an international conference on global warming involving world leaders was held in Rio de Janeiro. In October of 1993, he issued his Climate Change Action Plan with the goal of reducing ghg emissions in the US to 1990 levels by the year 2000.
