Do scientists disagree about the greenhouse effect and global warming?
No! Scientists seldom agree 100% on anything, but the vast majority of reputable scientists agree that increasing levels of certain atmospheric gases (like CO2) contribute to global warming. There is essentially no disagreement that growing use of fossil fuels on the current upward trend will lead to increased global warming. If there is disagreement, it is regarding the impact and timing of consequences due to this warming. Some models predict catastrophic effects like rising sea levels within our lifetimes. (Indeed, we can already observe substantially increased melting of polar ice.) Some predict stronger hurricanes immediately. (That additional heat must go somewhere, somehow.) Others say damaging effects are farther in the future. To learn more about global warming and hurricanes click here.
