A report in Science magazine (subscription required, but abstract available) explains that new ice core samples taken from polar ice sheet "allow researchers to place modern changes in the context of natural variations over hundreds of thousands of years." Scientists now have data that shows that the current climate change is happening faster than any in the last 650,000 years. This reinforces "the view that greenhouse gases and climate are intimately related."
Lets hope this new report can put the debate to rest.
