Looks pretty safe at the moment, I think storms may be variable and sunspot activity might get erratic. If a change was underway it would be measurable.

An extra heating effect

So far I have not seen any discussion on thermal gradients at depth.

I was wondering if the restriction of the heat loss by the earth due to its thermal blanket of CO2 may have any calculable effect. That is would a rise in surface temperature of the planet by a meer 0.5 to 0.7 degrees translate to greater internal thermal activity.

The earth does get hotter the deeper one goes hence we have plate tectonic movement. If the temperature gradient all the way down was consistent no great change. However if the earth is a generator of internal heat and unable to dump it a thermally graded effect may translate to much higher temperature say into the hundreds of degrees.

This would then pose a more serious problem and have hidden consequences. Higher plate movement potential due to lesser viscosity of the underlying magma. Great numbers of plate movements or thinning of the crust means more tidal waves more frequently and potentially with greater severity. Increased volcanic activity may also be a possibility.

Even in the Antarctic the ice sheet is over 2000 metres thick. A warming at depth could be the cause of the 14 huge fresh water lakes under the Western Antarctic ice sheet. Warming at depth would be far more seroius than surface warming as it could enable the ice sheet to slide far more quickly into the ocean.

There is a positive here, a rough positive at best. An ice age brought on by cataclismic event depending on severity and world preparation may be preferable to global warming. Cooler climates do seem to have better social community venues due to the need to make the best use of heating resources. This last point is just a perception of the tolerance people have of the smell of sweat which strangely enough is more noticeable in a hot climate.
