Obviously science is wasted on you.
The butterfly effect is a descriptor of the elements of chaos, and, cause and effect.

Atmospheric methane is not that big of a concern.
Current atmospheric methane isn't that big of a concern, yes. But please reread my post a little more carefully. I was talking about all the methane that have been trapped in the glaciers are being and will be released due to rise in temperature. Much of it will come from the tundra. Once it happens, it will be a problem.

Exactly.

There are enormous quantities of naturally occurring greenhouse gasses trapped in ice-like structures in the cold northern muds and at the bottom of the seas. These ices, called clathrates, contain 3,000 times as much methane as is in the atmosphere. Methane is more than 20 times as strong a greenhouse gas as carbon dioxide.

Now here's the scary part. A temperature increase of merely a few degrees would cause these gases to volatilize and "burp" into the atmosphere, which would further raise temperatures, which would release yet more methane, heating the Earth and seas further, and so on.

There's 400 gigatons of methane locked in the frozen arctic tundra - enough to start this chain reaction - and the kind of warming the Arctic Council predicts is sufficient to melt the clathrates and release these greenhouse gases into the atmosphere.

Once triggered, this cycle could result in runaway global warming the likes of which even the most pessimistic doomsayers aren't talking about.

Supposedly, at the end of the chain of events is the start of a new ice age.

Whether natural or man-made or both, those cycles will continue and become a huge problem. Sooner or later Europe, the US and other places will be covered by glaciers again. Some say those changes can be rather quick. We should start to think about that now so that we can prepare by developing emergency plans and international agreements. I mean, we have divided the world into countries with borders. Where will those hundreds of millions of people move to when that happens again? Will southern countries open their borders? Lots of questions...

Yes, adding CO2 does contribute (however insignificant) to climate change, and so does paving asphalt.

Also, it should be well known that climate models are in their infancy. I would not treat them as reliable.

Finally, this is becoming my favorite phrase:

"Man is causing uncertain effects of uncertain quantities on climate"
Global warming and climate change are man made controversies, with no substance, other than to accomplish economic and political aims.

It's getting soze that just talking about the weather has become downright rude.

Everybody can just go the fk back to Africa where they came from.

These folks don't realize if it weren't for "global warming" or I should say the "greenhouse effect" the earth would be a big ball of ice. I guess that is what they want.
