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.

In an attempt to detect the ‚Greenhouse Effect‘ they have set a criteria of an additional 0.5°C rise over the 1990 temperature, itself a 0.5°C rise over the 1900s temperature. Depending on the strength of the effect (forcing) the 0.5°C threshold could be reached by 2002 (obviously not) or not until 2047 (probably will).
The latest data set I can find (most seemed to stop updating in 2010) is this:
It is borderline as to whether we have reached the 0.5°C rise over 1990 yet but we are still within the range of the prediction so it has not yet been invalidated.
