After two previous reports on the effects of global warming in August and February, here is this section devoted to the concrete solutions that it is still possible to implement so that humanity adapts. For IPCC experts: “half measures are no longer an option”. The facts are there: our world is already 1.1°C warmer than when the industrial era began in 1850. This is already leading to more forest fires, heat waves, lower agricultural yields, however, for the moment, the adaptation of public policies remains below what it should be.
The report will detail the various technical solutions, but among the avenues on the table, there are reflections on the evolution of the agricultural model and the place of livestock farming, which is a major emitter of greenhouse gases and there are the capture of CO2, either technically (by filtering it at the outlet of factory chimneys for example), or naturally, by developing carbon sinks via vegetation, and by fighting against deforestation. Scientists have also looked into the organization and architecture of cities, so that they become more sober in terms of energy consumption and transport. And they weighed the impacts of the different possible energy mixes in terms of greenhouse gas emissions.
The good side of this IPCC report is therefore that it shows how to act, but it is a roadmap that it is urgent to follow. In its previous August report, the IPCC predicted that the threshold of +1.5C of warming (compared to the pre-industrial era) could already be reached already around 2030.
Like all IPCC reports, the report presented is a synthesis of international knowledge on the evolution of the climate at a time “t”. This report is the result of five years of work, hundreds of studies have been scrutinized, more than 270 experts have contributed to it, and it was unanimously adopted by the participants, which means that everything written in this report makes scientific consensus.
But after this scientific consensus, the whole challenge now is to accelerate political awareness around the world despite the war in Ukraine and health uncertainty.
