CLIMATE CHANGE
In recent years, no scientific issue has generated such heated political debate as the concept of climate change, or global warming.
Some politicians and businesses say that the evidence for climate change is not conclusive or that, at the least, any changes are not anthropogenic – caused by human activity. For some, the idea of climate change is a hoax. But around the world, almost all scientists – 97 percent by some estimates – believe that climate change is real, and many say deforestation and the rampant burning of fossil fuels, among other causes, have increased the level of carbon dioxide and other greenhouse gases in our atmosphere. These gases trap heat in the Earth’s atmosphere.
It is true that Earth has warmed and cooled many times over the millennia. Changes in the level of solar energy reaching Earth or massive volcanic eruptions, for example, can lead to climate change.
According to NASA, signs of global warming include an increase in ocean temperatures and record warm temperatures worldwide several times since 2005. Despite these and other facts, some people either deny climate change is real or zero in on some points still disputed by scientists and try to use them to undermine the whole concept. While debates go on, most scientists accept the verdict of the Intergovernmental Panel on Climate Change: “Scientific evidence for warming of the climate system is unequivocal.”
