Looks like scientists are baffled that the earth warms and cools regardless of what man does to the earth.

Many people have pointed me to this story, I wanted to read about it a bit before posting it. Almost two years ago, when this blog was in its very first month, I posted this story on the puzzling leveling off of global methane concentrations. FYI Methane has a “global warming potential” (GWP) 23-25 times that of CO2.
CDIAC has an interesting set of graphs on methane, the first of which shows that indeed global concentrations of CH4 through 2004 have leveled off:
This one on latitude -vs- concentration would surely seem to point to anthropogenic sources of CH4:
So here is yet another addition to the puzzle, which seems to point in the opposite direction:
MIT scientists baffled by global warming theory, contradicts scientific data
From: TG Daily By Rick C. Hodgin
Boston (MA) – Scientists at MIT have recorded a nearly simultaneous world-wide increase in methane levels. This is the first increase in ten years, and what baffles science is that this data contradicts theories stating man is the primary source of increase for this greenhouse gas. It takes about one full year for gases generated in the highly industrial northern hemisphere to cycle through and reach the southern hemisphere. However, since all worldwide levels rose simultaneously throughout the same year, it is now believed this may be part of a natural cycle in mother nature – and not the direct result of man’s contributions.
Methane – powerful greenhouse gas
The two lead authors of a paper published in this week’s Geophysical Review Letters, Matthew Rigby and Ronald Prinn, the TEPCO Professor of Atmospheric Chemistry in MIT’s Department of Earth, Atmospheric and Planetary Science, state that as a result of the increase, several million tons of new methane is present in the atmosphere.
