There is no doubt the planet is warming. What scientists continue to debate is the extent to which humans are affecting global temperatures and causing climate change. But the majority of scientists who study these issues around the world—including those with the World Meteorological Organization, the Intergovernmental Panel on Climate Change (IPCC), and the U.S. National Academy of Sciences—agree that humans are the main force behind the sharp global warming trend of the past century. Most scientists agree that the climate changes caused by global warming will never be completely predictable, but that they present serious risks—more extreme temperatures (hot and cold), greater storm intensity and frequency, more frequent droughts and floods, and rising sea levels—that warrant immediate efforts to reduce emissions from fossil fuels.
