Climate: the tipping point towards irreversible warming crossed?

The tipping point towards irreversible global warming has perhaps already been crossed, with consequences " Cascade " for the planet, warned Tuesday June 15 the German head of the largest scientific expedition ever led to the North Pole."Only the assessment of the next few years will determine whether we can still save the Arctic sea ice present all year round through consistent climate protection, or whether we have already passed this important tipping point of the climate system", underlined Markus Rex in Berlin, eight months after the return of the international mission carried out during one year in the Arctic."We may wonder if we triggered the start of the explosion""The disappearance of summer ice in the Arctic is one of the first mines in the minefield, one of the ...

Bill Gates urges innovation in agriculture against climate change: "The longer it takes, the worse"

Microsoft founder Bill Gates today warned that "hundreds of millions of farmers" are already feeling the effects of climate change and encouraged innovate in the sector, at an event of the Food and Agriculture Organization (FAO).

Will there be water for everyone in 2030?

► "We must rationalize agricultural use which takes up 70% of the resource"Celine Robert, water and sanitation manager at the French Development Agency“We must distinguish the water resource from access to drinking water. The map of water stress does not necessarily match that of the lack of drinking water. So the Democratic Republic of the Congo is a water tower. However, 40% of its population has only a water point less than thirty minutes from home, as in the whole of sub-Saharan Africa. 165 billion euros should be invested per year for universal access to drinking water, according to the World Bank. We are not on the right track. → REPORT. Blackouts, no running water ... Mexico is thirstySeventeen countries already take more than 80% of their resource. However,...

Heïdi Sevestre, the voice of the glaciers

There is something disconcerting about her. Heïdi Sevestre spends most of his time seeing the devastating effects of global warming on glaciers and warning the world of the danger he is running. Yet she is also one of those who almost always displays a fresh and radiant smile. When asked for her secret, the scientist naturally answers: “I'm fortunate enough to be deeply passionate about what I do, so I cultivate it. If I lose my faith, who will fight for our future? "At 33, this specialist in glaciology has just completed an unprecedented mission in the Svalbard archipelago, in Norway: the first “zero carbon” scientific expedition. Loaded with a sled weighing about twenty kilos and equipped with touring skis, she traveled, with three colleagues, the main island of Sp...

“Utopias made in the world”: the treatise on the economy of wisdom by Jean-Joseph Boillot

Utopias made in the world. The wise man and the economistby Jean-Joseph BoillotOdile Jacob, 416 p., € 25.90In economics, we usually distinguish the “orthodox”, who swear by the hidden but efficient hand of the market, from the “heterodox”, who denounce with more or less success the ideological presuppositions of the dominant theory. This is forgetting the “iconoclasts”, those who think outside the marked paths of established models and do not hesitate to “wet their shirts” to verify, in the field, that their ideas match the realities of the world.Jean-Joseph Boillot is of this caliber. Agrégé in economic and social sciences and doctor in economics, this former adviser to the ministry of finance did not cease, during his career, to travel the planet, from Europe to China...

Ecology, the shock of the generations? Conference debate to follow with La Croix on June 17

On the one hand, young people, aware of the ecological disaster; on the other, the older ones, at the same time still carefree, and yet responsible for the situation. It is in this form of a generational conflict that the media and politicians generally comment on the climate movement, and the growing concern for ecology. They want as proof these young people, who walked for the climate throughout the year 2019-2020 in the cities. And also the popularity of a figure like Greta Thunberg. Or even the aspiration of these generations to occupy meaningful jobs, their desire for consistency between their life and their thinking.This rhetoric is effective in media terms. But does it correspond to reality? What do we know about this “ecological generation”? Is it self-cont...

Disappearance of the viviparous lizard: how an animal species goes extinct

It is the story of a small lizard, which you may have come across one day for a walk, at the edge of a shady pond. Short head, thin legs and mosaic of scales tinted from beige to brown with metallic blue reflections on the tail. You might even have mistaken him for his cousin, the wall lizard, he looks so much like him. Yet its story says much more about our lifestyles and the already real impacts of climate change on the fauna and flora in France.→ MAINTENANCE. Biodiversity: "We must protect the territories now"In New Aquitaine, more precisely in the Landes triangle (between Landes and Gironde), this small reptile is one of the first species threatened with extinction due to climate change.

One of the next five years will be the hottest in the last century and a half, according to experts’ prediction

In the five years 2021-25 it is likely that at least one year is the hottest on record and temperatures are already close to the limits recommended not to exceed the Paris Agreement, warns this Thursday a new report from the World Meteorological Organization (OMM). The study indicates that there is a 90% probability that at least one year in five years 2021-25 will be the warmest of the last century and a half, with an increase in temperatures compared to pre-industrial levels of between 0.9 and 1.8 degrees. However, the study of probabilities, prepared with data from the UK Met Office, reduces to 40% the chances that in this five years the average temperature will exceed the figure of 1.5 degr...

Climate: Amazonia at the heart of concerns

There have been a few articles in the newspapers. And calls here and there, from NGOs and personalities, to react for the Amazon. Far, however, from the mobilization that one would have expected, in particular from the political world, as the results of the study published at the end of April in the journal Nature Climate Change are striking. Thanks to unpublished satellite data, a team bringing together scientists from INRAE, CEA and the University of Oklahoma (1) studied the evolution of carbon stocks in the Brazilian part of the Amazon, between 2010 and 2019.→ ANALYSIS.
