If this survey is real the messages these young people are receiving are completely wrong.
We need to reduce our impact on our planet but CO2 is a complete red herring. The current ECS (temperature increase for a doubling of CO2 in the atmosphere) is centred around 3°C (IPCC AR6). The 2°C will destroy civilisation is simply made up.
Although interesting, being the longest measured temperature series, the CET is not very helpful in discussing global warming as it is just 3 points in England which may or may not reflect global conditions. What is the global average temperature?
There are a number of series run by various organisations. The UK Met office used to run a comparison but stopped updating this is 2010 (why?)
There are significant differences between the two hemispheres, the northern hemisphere being similar to the CET with a drop 1950 - 1970, a rise of around 1°C to 2000 and then a flattening off.
IPCC AR5 split there global temperature between land and ocean. This tends to smooth out the drop in the northern hemisphere between 1950 and 1970. Again we have a rise of around 1°C and they note the flattening off after 1998.
IPCC AR6 presents a much more extreme view. The previous reduction in the rate of rise has disappeared with no obvious explanation other than maybe ‘new datasets and methods’ (fudge the numbers to get what you want). The earlier warm periods and the little ice age are also not there.
I accept that as we learn more and develop new techniques that older data needs to be revisited. I am suspicious when every change moves the data nearer to your prediction and the political goals. Finally a couple of thoughts on FLOP26:
