As I recall, the current warming trend is about 0.03°C per year.
As you can see from this plot:
http://en.wikipedia.org/wiki/Image:Ice_Age_Temperature.png
Immediately coming out of the last ice age 10,000 years ago, the planet warmed on the order of 8°C over a period of about 5,000 years, which is an average of about 0.0016°C per year.
If these numbers are correct, we're now warming at a rate of about 20 times faster than when we were coming out of the last ice age.
Are these numbers correct? If so, considering that we're not coming out of an ice age right now and yet we're warming 20 times faster than if we were, how can you
a) Claim this is a natural effect?
b) Deny that this is a problem?
