Is climate change causing increased volcanic activity? (million, own, regular)

[Matadora]

I suggest you Google the different footprints and how science can differentiate between human and natural CO2.

I will be happy to lecture on this tomorrow.

Good night

Please send some Glowball Warming to Long Island; it's ****ing in the 40's this morning in JUNE!

It appears as though increased CO2 in the atmosphere is causing increased volcanic activity.

I noticed a similar thing near my neighborhood...a rash of flat tires caused a bunch of nails to form in the road.

Yes, I have noticed that myself. Also, I noticed among my patients that those with COPD tend to take up smoking.

There were of course "EXTREME" climate processes prior to mankind arriving on the scene. These can perhaps be classified into two different groups.

The first can include really big changes but they occur very slowly, although sudden on a geological time-scale. So the end of the last ice age saw a rise of perhaps 6°C in global temperature over 8,000 years or 55 million years ago the PETM which saw similar temperature rises over 40,000 years (long enough, for instance, for horses to adapt to the temperature increases by slowly evolving from pony-size into the size of large dogs).

The second group are far more sudden, the suddenness often obvious. A big volcanic eruption (Mt Toba 74,000 years ago), a meteor strike, or a sudden influx of fresh water that destabilizes ocean currents (as per Dansgaard–Oeschger events). This second group can still have very very big local effects but obvious causes that soon dissipate (although D-O events can take 2,000 years to return to the prior climate).

But in all this, I'm not sure what you're trying to argue. If we wait long enough there will eventually be a mega-volcano blow its top, or a big meteor will eventually strike the Earth. (There isn't enough ice about for a D-O event to occur without an ice-age.) So are you suggesting we set about creating our own climatic disaster to allow us to practice for how to respond to the real thing?

Or do you want an explanation for every wobbly bit of paleoclimate before you will accept the blindingly obvious fact that it is humanity driving today's warming climate and it will not end well if we don't do something about it?
