The average temperature of the earth has not warmed over the past 8 years.
Boy, if I ever hear this one again...
1998 was an El Nino year, and El Nino years are years with higher-than-average global warmth. The next year was a La Nina year, and it was colder. In the ensuing years, the global temperature anomaly has been between the 1998 record and the 1999 subsequent minimum, and (with variability), the years have gotten warmer -- to the point that 2005 was almost as warm (some analyses indicate "as warm") as 1998, without an El Nino event. This last datum indicates that the warming trend is still ongoing.
I'll take your word for it, but I'm going to fact-check you.
In today's world, it's best to link to an authoritative data source for such assertions.
Okay, man, I gave you the benefit of the doubt, but I've gotta call "B.S." on ya. Sorry. It isn't personal, just that the actual data doesn't at all support your claim.
Here's a source:

Things ARE heating up. Slowly. The actual CAUSE(S) may be in question, but the change in temperature isn't.
