Global warming skeptics will receive yet another blow as yet another study proves its veracity and actually predicts large-scale changes in our climate. The Earth has a delicate balance of life that is supported on a small range of temperature differences and any alterations, although not entirely life-threatening can cause a significant difference in the way we live, earn, and enjoy. The economic and social impacts can be far-reaching.

Based on fossil records of terrestrial plants and oceanic plankton, suggests that the world's climate is highly sensitive to atmospheric carbon dioxide (CO2) levels, finding that a doubling of CO2 concentrations can raise global temperatures by at least 4 ºF (2.2 ºC)
