By Robinson Shaw Global warming caused by human activities continues to impact weather around the world. As much as the world tries not to warm up to heat-trapping greenhouse gases, it continues to warm up from them. Climate change is already causing an increase in the number and intensity of natural disasters, according to a study released Friday by the World Wildlife Fund.
Climate change brings about a global redistribution of the costs and benefits of the weather.
Global warming is the probable, not unequivocal, cause of extreme weather events and related occurrences such as sea-level rise. There is no equivocating that Earth is heating up. Concentrations of greenhouse gases such as carbon dioxide, methane, nitrous oxide and chlorofluorocarbons have increased since the pre-industrial age and snowballed since 1960, according to the report. The increase is the result of human activities connected in large part to fossil fuels, land use and industrial processes. Related Sites For the complete WWF report, go to climate change .
