"The following is from:

1,700 years ago; 413 feet (126 meters)
Carbon dioxide levels measured 275 parts per million (ppm)*
Global average temperature was similar to today's.

134,000 years ago; 2,052 feet (1,876 meters)
Carbon dioxide levels measured about 290 ppm*
Temperatures were warmer than today

WE ARE NOW APPROACHING 400 PARTS PER MILLION, SCOTT..."

If the Carbon dioxide level is over 300 ppm today, then why is the temperature LOWER than it was 134,000 years ago?
Could it be that the atmospheric PRESSURE is lower today than it was 134,000 years ago?

"It looks like the Methane and CO2 are keeping the tempatures from plunging to previously unseen lows."

You may be right about the "tempatures".

I'm wondering why it is that the air temperature is lower at a higher altitude?
Could it be that it has something to do with the air PRESSURE?
What can change the atmospheric pressure besides sunlight, could it be the radioactivity that has been distributed into the atmosphere?
