A few more degrees could change the face of humanity

One, two, two and a half… only a few degrees more. But in concrete terms, should we be worried about these few extra degrees? What changes can global warming bring about?
To answer this question scientifically, discover the video published by Le Monde, which was created in collaboration with Rodolphe Meyer, doctor in environmental sciences and creator of the Youtube channel: Le Réveilleur. It presents some of the most problematic consequences of climate change, and gives you the keys to understand why it is a major challenge of the 21st century.
Global warming is mainly reflected in a gradual increase in the planet’s overall temperature. In the space of 40 years, the global temperature has already risen by one degree, with the continents warming much more than the oceans.
Despite the uneven distribution of this warming in time and space, all forecasts confirm that over the next century, the temperature of the planet will inexorably continue to rise by a few “small” degrees as our greenhouse gas emissions also continue to increase…
This rise in temperature is affecting the infrastructure in which we live as much as our activities, and its consequences are increasingly devastating. The agriculture that feeds us is particularly affected by increasingly frequent, severe and long heat waves. In 2003, heat waves led to 15,000 deaths in France, caused by an atmosphere that is too humid and saturated with water vapour, which prevents normal evaporation of human perspiration and cooling of our bodies…
But climate change is not just increasing temperatures. It also changes the water cycle. Increased precipitation in wet regions leads to more and more floods. Conversely, dry regions are affected by more and more droughts. Between melting glaciers, rising water levels and floods, the modification of the water cycle could have deadly consequences for humans, but also for all biodiversity.
The Oceans Conference opens a new chapter in global action for the oceans. Jointly organised by the Governments of Kenya and Portugal, it aims to use science and innovation to deliver the solutions needed to achieve the 17 United Nations Sustainable Development Goals for 2030, including the goal of sustainable ocean protection.
Created in 1998 by the L'Oréal Foundation and UNESCO (United Nations Educational, Scientific and Cultural Organization), International Awards "for Women in Science" recognises and supports outstanding women in science around the world. Each year, five laureates are recognised for their contributions to the advancement of science, in the life sciences or physical sciences, mathematics and computer science.
In Brest, on 11 February 2022, at the invitation of the President of the French Republic Emmanuel Macron, some forty heads of state and government met to make joint commitments to preserve the oceans.

World Oceans Day on 8 June 2021 was an opportunity for the CNRS (Centre National de la Recherche Scientifique) and Ifremer (Institut Français de Recherche pour l'Exploitation de la MER) to mobilise the French scientific community around a new PPR (Programme Prioritaire de Recherche) targeting the ocean-climate ecosystem.
From next September, Ifremer (Institut Français de Recherche pour l’Exploitation de la MER) will set up a new Stakeholder Committee (CPP).
What if the health crisis could reintroduce science and scientific debate at the heart of society ?
