For what its scientists say is the first time ever, a study has directly linked climate change's effects to human behavior (the closest another study has come is in a 2007 UN report, which stated that human-induced warming was "likely" to have an effect on Earth's systems.The researchers analyzed published data on 829 physical systems like melting glaciers and warming bodies of water, as well as 28,800 living plant and animal systems within the past few decades. And in 95% of the physical systems and 90 percent of the plant and animal systems, the changes were consistent with the predicted effects of a warming climate. One scientist called it "highly unlikely" that the changes were due to anything other than human effects.
And others are worried about the amount of change that has occurred with just a one degree increase in temperature: cannibalistic polar bears, melting glaciers, and earlier-blooming plants, to name a few.
What say you now, naysayers?
