hi im doing a debate tomorrow on global warming, i am arguing that it DOES exsit. the opposing side who don't believe in global warming want to say that increases in temperatures don't cause sea levels to rise, instead the tectonic plates of the earth cause changes in sea level.

Question

HOW COULD I COUNTER THEIR POINT?
ANY IDEAS THANKS!

Answer 1

These two sites have proof that global warming is related to rise in temperature.

This article argues against the effect of tectonic plate shift as a cause of warming.

Answer 2

Global warming is real in the past 100 years. It is about 0.8 degree centigrade. What is controversial are the main causes.

I have recently learned of the arguments that the changing contour of the sea bed, due to tectonic plate motion, may have an effect as large or larger than global warming has had SO FAR in increasing the level of the sea. It is going to be hard for either side to "win" that argument based upon what is known right now. By all means, check out this recent article:

The magazine Physics Today recently published an article (March 2008, page 50) that argues against the greenhouse effect being as important as most scientists say.
