So the world is cooling, no, it's warming , oh, whatever, ok, how has mankind got this far, oh yeah I know, because of it's ability to adapt to different situations, ok, lets carry on adapting to what life throws at us, next.

Nobody questions whether humankind can adapt and survive as a species, and in fact nobody ever has. The only question is, at what cost?

We have a hundred and fifty years of temperature data. The last fifty of those years were more precise by orders of magnitude than the first fifty. A hundred and fifty years ago today, J.C. Maxwell's unified equations for electricity and magnetism had not yet been published. Radio had not yet been invented. Transatlantic telegraphy had not yet been successful.

Actually we have much more temperature data than that. We have tree ring and ice core data going back over one hundred thousand years.


I was, of course, referring to recorded temperature readings which started about 1850, not proxy reconstructions which aren't much more than estimates.

They're a lot more than estimates. They used physical temperature measurements to calibrate the data.

Yes, what cost, that is, the question, now I suspect if we can carry on as normal i.e.our present lifestyles or better, people would be all ears, but, if it is the reverse of all that,and we had to quit or reduce the use of our current technology and privlidges, well, we can see the reticence, for many it seems will not accept any notion of going backwards.

Now, if the available climate data suggests the climate started to shift with the industrial revolution, that gives us a big hint as to what we were doing. So, what was before the industrial revolution, hmm, lack of heavy fossil fuel burning and people being less centralised, which could mean that the concentration of  fossil fuel burning industry all in a small area, could have been the problem, nature could not cope. Also a thing that is common with heavy industrial areas, is the lack of green vegetitation, photosynthesis cleans the air.

But fossil fuels, what are they, the residue of things that have died millions of years ago, we are technically using death to fuel our life, but then, that is recycling, perhaps we will become the fuel of the far away future, if we don't become the food first.

Perhaps the real cause of all this, if a cause is sought, is human arrogance and greed, a notion that some have that the earth and nature were put here for our use and if it's there, take it, not just some of it, but all of it whether we need it or not. I believe some religious scripture actually promotes this, by interpreting ancient notions as to what the deity meant, nature and the earth were put here for the human to use ?

They're a lot more than estimates. They used physical temperature measurements to calibrate the data.


Which led to slightly more accurate estimates, but still not even as reliable as the real temperature readings from 150 years ago, which isn't as reliable as temperature readings now.

They are also too sparse to give any kind of real picture on a global scale. They are at a disadvantage in every way to actual temperature readings, except that they go back farther in time.
