I can see it happened if it expends but not when if it shrinks. This may perhaps causes the atmosphere to thin as it stretches and more UV light penetrates to earth surface. I am just using my common sense, i maybe wrong. I do though teach my students that earth does not expend nor extends and I prove to them...

@Ahmed, I like your line of reasoning. I think the earth can shrink and expand.

Dear Dr Gwazah,

Please I want to learn how earth shrink or expands? What are the responsible forces for shrinking and expanding of earth?

@Iticha: The reason may not be very clear now. Come to think of it, if the earth shrinks the distance between the sun and the earth will certainly decrease thereby causing a rise in temperature of the earth which will lead to climate change.

No. I said the distance will decrease according to Newton's law of universal gravitation.

Kenneth,

If am not mistaken, I think in his brilliant assessment, Ales mentions the 'GH effect' and not CO2 exclusively. I think water vapour should be top on the list, without which added CO2 is an ineffective GHG. Therefore, the rise in GHGs in general have contributed to the mild and warmer climates we enjoy today, but which most are not grateful for.

Cheers

I think that a discussion that relate CC to the expansion or shrinking of Planet Earth is a bit misplaced. At least for me it does not sound in anyway convincing.

Callendar was clearly wrong about the increased CO concentration. At the time it was insignificantly higher than in the centuries before his time. So what is the meaning of this reference to Callendar in a period in which temperature measurements were not very relaible either

Kenneth Towe

I read his paper: fully outdated

Again: the increas in CO2 concentration at the time he wrote his paper was insignificant. So Why are you giving him as a reference

And again until the 160s the increase in the CO concentration was still insignificant in a climatological sense

So what is your argument here?

Ken

You did not (want to) learn a iota from all discussions in the past years here at ResearchGate

Hahahaaaa , Dear Kenneth you mean the IPCC is a Bible to some people?

Well,

Considering the Interior heat flow as one of the global heat balance, so disturbance in earth crust may relatively generates warming.

Sincerely
