The latest report from the Intergovernmental Panel on Climate Change has tested all future scenarios for our Planet and strongly encourages the goal of limiting global warming to +1.5°C within the next three years for us avoid a catastrophic fate.

[EN VIDÉO] The story of global warming in 35 seconds By graphically integrating temperature measurements in almost all the countries of the Globe between 1900 and 2016, this animation shows in a striking way the increase in the number of “temperature anomalies”, therefore deviations from an average. We see that in just over a century, the proportion turns red.
The Intergovernmental Group of Experts on the Evolution of the weather (IPCC) released its new report on Monday 4 April. This new chapter, made up of several volumesdraws up the state of the most advanced knowledge relating to the climate changeand it would seem that the situation in which we find ourselves leaves us only three years to limit the damage of anthropogenic warming and save our skin.
Stabilize temperature rise at 1.5°C
The IPCC scientists evaluated several scenarios of the future of our Earth and to limit a global warming at +1.5°C above pre-industrial levels, they warn that “ the emissions of greenhouse gas must peak before 2025 at the latest to keep our world livable. This scenario is the least critical for the future of our planet and it is of course the most ambitious of the treaty of the Paris Agreement of 2015, which keeps the rise in the average temperature well below +2°C. .
However, without the immediate reduction of emissions in all sectors, this objective will be impossible and the consequences will be terrible. Indeed, the higher the temperatures, the more the warming worsens and results in multiple consequences like an increase in the waves of heat, sea level rise and other extreme weather events; but also by repercussions on food security, the environment, health and sustainable development.
It is also necessary to understand that it is not because we reach the objective of +1.5°C or that we manage to be below that there will be no problem. Each additional fraction of a degree that we take generates additional impacts and risks that are more complex to manage and to which we must adapt. Moreover, the difference between an increase of 1.5 and 2°C is very significant and even fatal for certain regions of the world. The +1.5°C target can only be achieved when the global temperature stabilizes, i.e. when the world has reached the carbon neutralityremind the experts of the United Nations.
A minimum warming of 3.2°C if we do nothing
However, it would seem that we are not on the right trajectory. The current warming is estimated at +1.09°C and the greenhouse gas produced by human activities are constantly increasing. According to the latest IPCC report, our modern behaviors and lifestyles are leading us towards a disastrous warming of +3.2°C in 2100.
To avoid this dreadful future, the IPCC affirms that there is still time to act during these next three years during which it is possible to reverse the trends to preserve us from this disastrous fate. Climate experts say the 1.5°C target is still achievable but requires unprecedented changes at all levels of society.
