Why the UN Report is right to say we’re heading for at least 3 degrees of warming

 100% Renewables 2nd Dec 2023

Despite a flurry of headline-jerking agreements at Dubai’s COP28 a UN Report suggests that global warming will reach 3 degrees. This conclusion, issued by the UN Environment Programme’s ‘Emissions Gap Report’, is based on the continuation of current policies. This assumes, for instance that in the UK and the USA, the targets for net zero greenhouse gas emissions by 2050 not achieved. This, by the way, is by no means an unreasonable assumption. In fact, as things stand at the moment, it’s dead right!

Achieving the 2050 net zero target means that all heating, transport and industrial energy uses need to be decarbonised. Then the production of electricity will have to be greatly expanded. That, actually, is the easier task eg if you consider that the whole of the UK’s energy supply could be supplied by electricity from offshore windfarms occupying less than 10 per cent of the UK’s seawaters……………………………………………….

it does seem likely (on the basis of the UN analysis) that we are facing a temperature increase of 3 degrees above industrial levels. Temperatures have now risen by 1 degree and the effects are apparent. Yes, these COP events are, as Greta Thunberg said, by and large, just ‘blah blah blah’.  https://100percentrenewableuk.org/why-the-un-report-is-right-to-say-were-heading-for-at-least-3-degrees-of-warming
