What is net zero and why is it necessary?
Former Community Member
Decarbonising quickly and effectively to hit our net-zero target by 2050 requires urgent, clear and decisive leadership. Our short video looks at the skills requirements for delivering this target and breaks down the results from our recent Skills for net zero and a green recovery survey.

Roger Bryant: Please read the graph again. The CO2 concentration has risen around 20 ppm (~390ppm in 2010 - ~412ppm in 2020) in the last 10 years. It will probably rise another 20 ppm in the next 10 years which will be less than 440 ppm. Here is the actual Mauna Loa graph that may be easier to read.
If you compare the CO2 levels with the global temperatures over the last 25 years there is no correlation. Currently the temperatures are dropping slightly. I will be interested to see what the IPCC AR6 has to say. AR5 noted the ‘pause’ which various so called climate scientists tried subsequently tried to make disappear along with the Medieval warm Period and the Little Ice Age that followed it.
Consensus is the last resort when the facts don’t work. Consensus kept the Earth centred view of the solar system when the calculations showed the sun was at the centre. 100 Authors wrote that Einstein was wrong, was he?
There is no pause. 1998 was an exceptionally warm year, and the following years weren't quite so warm. Every year since then, the climate change deniers have been telling us that there is an unexplained pause in warming. They keep saying that, even though the temperature has started going up again and the 1998 temperature has been beaten repeatedly.
