The report titled “AR6 Climate Change 2022: Impacts, Adaptation and Vulnerability” (https://www.ipcc.ch/report/ar6/wg1/#TS ) from the IPCC Working Group I (WGI) (IPCC-Intergovernmental Panel on Climate Change) of the United Nations (UN) responsible for examining the physical science underpinning past, present, and future climate change, published on 9th August 2021, and signed by 234 top scientists from more than 60 countries, warns that the average temperature on the planet will increase by 1.5 degrees Celsius compared to the pre-industrial era.
The report emphasizes that this scenario is very likely to become a reality within the next twenty years. More specifically, the report emphasizes that the melting of Greenland’s ice and the rising surface of the seas – is now, with current data, an irreversible situation.
Five scenarios are presented, with the most extreme of them being the good and bad scenarios respectively and the rest moving in between.

- The good script
For the increase of temperature and greenhouse gas emissions for the current century, it is shown that the reduction of greenhouse gas emissions is achieved within the current decade and their final zero by 2050.
In this case the increase in average temperature can be left at 1.5oC. Achieving this scenario means adopting more sustainable practices around the globe.
- The bad scenario
In this case, we have a doubling of carbon dioxide emissions by 2050. Rapid rates of economic growth, depletion of the planet’s reserves of fossil fuels, with the average temperature on the planet’s surface rising by 4.4oC.
However, there are several doubts from scientists as to the accuracy of the scientific models used, disputes that were recently published in articles in the journal Science magazine -(https://science.sciencemag.org/content/364/6437/222) (please read the title analysis for more analysis «Scientific Prediction Models for Global Warming Are Problematic»).
