Despite ongoing harsh winter conditions in North America and Europe, a survey finds a consensus among scientists that global warming continues unabated. The University of Illinois-Chicago surveyed an international group of 3,146 earth scientists and found overwhelming agreement that during the past 200-plus years, mean global temperatures have been rising, and that human activity is a ongoing significant contributing factor in changing mean global temperatures. The survey was conducted by Associate Professor Peter Doran and former graduate student Maggie Kendall Zimmerman.

While the harsh winter pounding many areas of North America and Europe seemingly contradicts the fact that global warming continues unabated, a new survey finds consensus among scientists about the reality of climate change and its likely cause.

A wide range of Earth scientists say humans contribute significantly to global warming, suggests a poll conducted by the University of Illinois at Chicago. The poll should dispel doubts by some that a consensus about global warming exists among scientists, said Peter Doran, a University of Illinois
