This warming has been particularly strong during the last 20 years."

Q: But do most scientists agree with that statement?

A: Yes, Tom Jackson points out how most scientists now agree that the world is warming at an increasing rate. (Grollier's Pro/Con vol. 4)

Q: Are there any consequences as a result of global warming?

A: Some noted consequences are: "Retreating glaciers, thinning arctic ice, rising sea levels, lengthening of growing seasons for some, and earlier arrival of migratory birds." This statement is also from the National Academy of Sciences web site.

Q: Wouldn't those be considered negative consequences?

A: Retreating glaciers and thinning arctic ice mean that the sea levels are rising. Rising sea levels would mean that low-lyi

Q: Ok, but does global warming directly threaten humankind?
