Climate Change and Rising Temperature

Scientists have high confidence that global temperatures have risen and will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The IPCC predicts that increases in global mean temperature of less than 1 to 3 degrees Celsius above 1990 levels will produce beneficial impacts in some regions and harmful ones in others.

"Taken as a whole," the IPCC states, "the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time."

Of course there are always people who see things differently.
