Well I know all of that, but still.... Don't you imagine, if mankind were doing something to "increase" the temps, we would see the "top" temp being set each summer?

Record High Temperatures Far Outpace Record Lows Across U.S.

BOULDER—Spurred by a warming climate, daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows. The ratio of record highs to lows is likely to increase dramatically in coming decades if emissions of greenhouse gases continue to climb.
"Climate change is making itself felt in terms of day-to-day weather in the United States," says Gerald Meehl, the lead author and a senior scientist at the National Center for Atmospheric Research (NCAR). "The ways these records are being broken show how our climate is already shifting."

DIXIE: It went up to 136 degrees in 1922, and it hasn't been that high since... we aren't making the planet warmer.
The temperature reading from one thermometer in the Libyan desert in 1922 is irrelevant to global climate change; temperature readings from one thermometer reflect localized and possibly anomalous weather conditions e.g., . such as anomalous inversion layers.
DIXIE: Nominal rises and falls in median temps over a few decades, have more to do with sun cycles and solar activity, than something we are doing to increase the temps.
Solar irriadiance is at a minimum and should be having its maximum cooling effect, but temperatures keep rising. Solar output trends and cosmic ray trends haven't changed appreciably in 30 years. The best peer reviewed research on the planet has concluded with high confidence that the warming trend of the last half century cannot scientifically be explained by natural variation and is very likely due mostly to human emissions of GHG.
DIXIE: The median temp has risen by 1 degree Celsius in a CENTURY! Big fucking WOOP!
Scientific estimates are that global mean temperatures will rise several degrees over the next 50 to 100 years. Global mean temperatures do not mean every where on the planet will rise by the same amount. The higher latitudes and the arctic are susceptible to even higher degrees of warming, and ice sheets, snow packs, environment, ecology, weather, agriculture, water supplies, precipitation and nation's economies are scientifically known to be susceptible to significant climate shifts resulting from rapid changes on the order of a few degrees C.
