"The time series shows the combined global land and marine surface temperature record from 1856 to 2002."
And the following time series are representative of the change in global temperature record across the last 500 thousand years, note the minor uptick(i.e. 1856 to 2002 identified as "global warming") to a median temperature in an overall downtrend for the last 2400 years,
One's trend all depends on the time frame one wants to use to make a political point with.

I have no intention of getting into a broader discussion of "global warming" on this thread. I know you're out there. I have had some distractions in my personal life that have temporarily detracted from my ability to post topics and discuss them fully on FR. This "condition" may persist for a few more weeks. But as time allows, I will be glad to continue discussion on the topic. Just not here, and not now.
