Climate Emergency - The Next Decade

They are the "adjusted" records. The older the readings the more likely they are to be inaccurate.

Even modern readings are suspect given the influence of Human buildings, construction, agriculture, mining, transport and water extrraction on the environment.

A like for like comparion is impossible for any major City for example.

Yes. The article makes very clear that the further back in time the more inaccurate results are. The records have to be adjusted for the reasons you give so that comparison can be attempted.
How accurate the adjustment process is I don’t know but I am sure you will say it cant be done.
However I posted that not to make any point about climate change but simply to add more information to the question of when records began

While we might not have temperature records per se, a lot can be deduced from ice cores , fossilised tree rings and other indicators going back millions of years.
Anyway, I would think it wise to prepare for a fortnight at 40 deg c and ask yourself if your house/livestock facilities etc are up to the job There is a certain amount of thermal inertial in most buildings but once that’s caught up with external temperatures it can be extremely unpleasant indeed. We were very close to that situation this summer. How much closer do we need to get to a real crisis before folk think it might be a good idea to take adaptive action?
I’ve always resisted aircon in my home as it uses even more energy but if it became a matter of life and death and if it could be run on solar power that is abundant during a heatwave or if the energy could be stored then it would be as well to be in place ready, rather than something that occurs to us a fortnight into a severe heatwave.

Interesting point about tree rings, when dutch elm struck we had a lot to cut down including some huge ones which were recorded on an old farm deed in the 1700 hundreds, in some places the rings were so close together they were impossible to count accurately showing for several years there was very little growth then and few average years then two or three big growth years, as elms like wet conditions I assumed that the close rings were dry summers and big ones were wet ones, I suspect going back 300 years more could be learnt from those rings than some written record

When do climate records begin is an interesting point.

Why do all our climate data start in 1880?

When you see headlines about record-breaking temperatures, you're looking at a climate model still in progress

There is a continuous record going back to 1659 called the Central England Temperature record (CET) - look it up on the Met Office website , Hadley institute. Notice how the temperatures rise 2 degrees from 1690 to 1730 and then fall 1.5 degrees to 1880. This is very inconvenient , for anyone trying to prove global warming started at the begining of the industrial revolution in 1850 ,so the alarmists ignore all the data before 1880.

Climate is changing for sure. Probably a little bit of natural cycle and some of the CO2 effect. Reality is folks are not going to give up oil and gas though, even on the most aggressive forecasts for electrification of cars in america, Europe and China the drop in demand from current is less than 5million bbls per day. Governments need to get serious about infrastructure to cope. Water being the biggest issue. Like the Mohawk say, only the white man thinks it’s cool to cook outside and shyte inside.

Yes. I am aware. Of course the CET is not a global record

Where did the industrial revolution start ?

In a world supposed to be millions of years old, it’s not very long ago really is it?

Think you misunderstand how the atmosphere behaves.
Not that I have much knowledge on that but I could ask someone who knows if I could be bothered which I can’t. You will have made you mind up for your own reasons.
One question though. Do you consider as “alarmist” any one who looks at the evidence and concludes that the world is warmer and it’s down to man?

No, I don't anyway, but far as I’m concerned it matters not a jot whether it’s natural or man made, it’s just happening.

I do despise the zealotry and orthodoxy which surrounds it.

Far easier to make some (let’s face it) fairly minor adaptations to our infrastructure and lifestyle than attempt to change the weather back to some notional norm which has never existed.

To think that anything we could do in this country will make a whit of difference is hardly credible. In the global scheme of things our emissions will hardly register. What we do have is an excess of zealots who are determined to put us all in hair shirts . Net zero by 2050 has just not been thought through and would see widespread starvation.

No, but digging up fossilised carbon is a recent phenomenon.
