...but that methane really is a strong greenhouse gas isnt it.
, science already knows all about how “methane really is a strong greenhouse gas”
...when methane is compared directly with CO2.
And science also knows about how CO2 is a stronger influence,
overall—when compared to methane—on our climate.
...since methane disappears much more quickly, AND...
...since methane is measured in ppb (parts per
billion)...
...there isn't nearly as much methane as there is CO2.
So I hope you can see how the shorter time scale of methane’s effect,
along with the much smaller amount of methane (parts per billion,
compared with ppm for CO2),
means this “stronger” GHG doesn’t make as much difference as CO2 does, in the big climate picture.
That’s why the “radiative forcing” from methane is considered to be
smaller than the forcing caused by CO2 (
shown on the right, above).
===
did you ever look at any of the graphs that show both
temps and co2 levels and wonder why the temperature
rises before the co2?
Yes! And science already knows about how “temperature rises before the co2” on the geological time scale,
normally, in response to orbital (Milankovitch) forcing.
“The lag proves that …higher CO2 levels cause warming.”“The lag proves that rising CO2 did not cause the initial warming as past ice ages ended,
but it does not in any way contradict the idea that higher CO2 levels cause warming.”
===
or is that type of data not acceptable in the
global warming due to co2
realm?
in the “global warming due to co2” realm of science. These two points that you've mentioned above,
are accepted and understood by mainstream physics and chemistry,
and they are consistent with the mainstream views on global warming.
Do you think your two points somehow contradict the mainstream theory?
===
Or maybe you’re right on topic, focusing on methane,
because if the Arctic permafrost heats up too much more,
methane would likely become the bigger problem.
Arctic could become an overall source of carbon to the atmosphere.“If …a lot of permafrost thaws out, the Arctic could become an overall source of carbon to the atmosphere….”

“…methane, a greenhouse gas that is 30 times more effective in trapping heat in the atmosphere than carbon dioxide, is bubbling up from the continental shelf and leaking into the atmosphere. The estimated total: 8 teragrams — that's 8 trillion grams — per year.” ...[
fyi: 1 teragram = 1 megaton = 0.001 gigaton]
