Terrestrial ecosystems have taken up about 32% of the total anthropogenic CO2 emissions in the past six decades1. Large uncertainties in terrestrial carbon–climate feedbacks, however, make it difficult to predict how the land carbon sink will respond to future climate change2. Interannual variations in the atmospheric CO2 growth rate (CGR) are dominated by land–atmosphere carbon fluxes in the tropics, providing an opportunity to explore land carbon–climate interactions3–6. It is thought that variations in CGR are largely controlled by temperature7–10 but there is also evidence for a tight coupling between water availability and CGR11. Here, we use a record of global atmospheric CO2, terrestrial water storage and precipitation data to investigate changes in the interannual relationship between tropical land climate conditions and CGR under a changing climate. We find that the interannual relationship between tropical water availability and CGR became increasingly negative during 1989–2018 compared to 1960–1989

The climate crisis has begun to disrupt human societies by severely affecting the very foundations of human livelihood and social organisation. Climate impacts are not equally distributed across the world: on average, low- and middle-income countries suffer greater impacts than their richer counterparts. At the same time, the climate crisis is also marked by significant inequalities within countries. Recent research reveals a high concentration of global greenhouse gas emissions among a relatively small fraction of the population, living in emerging and rich countries. In addition, vulnerability to numerous climate impacts is strongly linked to income and wealth, not just between countries but also within them.

le rapport 2022 du financement du chaos climatique par les banques. Avec résumé en français.

Le financement des énergies fossiles par les 60 plus grandes banques au monde a atteint 4 600 milliards de dollars sur les six années qui nous séparent de l'adoption de l'accord de Paris, avec 742 milliards pour la seule année 2021. Ce rapport examine le financement des banques commerciales et d'investissement à l'industrie des énergies fossiles - prenant en compte leurs rôles de prêteur et d'émetteur d'actions et de titres de dette - et en conclut que, même au cours d'une année où les engagements « zéro émission nette » étaient très en vogue, le secteur financier a continué, par sa logique de business as usual, à alimenter le chaos climatique.

As a leading climate scientist, Paola Arias doesn’t need to look far to see the world changing. Shifting rain patterns threaten water supplies in her home city of Medellín, Colombia, while rising sea levels endanger the country’s coastline. She isn’t confident that international leaders will slow global warming or that her own government can handle the expected fallout, such as mass migrations and civil unrest over rising inequality. With such an uncertain future, she thought hard several years ago about whether to have children.

The world is dangerously off track to meet the Paris Agreement goals. The risks are compounding. Without immediate action the impacts will be devastating in the coming decades.

The Atlantic Meridional Overturning Circulation (AMOC), a major ocean current system transporting warm surface waters toward the northern Atlantic, has been suggested to exhibit two distinct modes of operation. A collapse from the currently attained strong to the weak mode would have severe impacts on the global climate system and further multi-stable Earth system components. Observations and recently suggested fingerprints of AMOC variability indicate a gradual weakening during the last decades, but estimates of the critical transition point remain uncertain.

A new report, published on 14 March, 2021 in the Royal Swedish Academy of Sciences’ journal Ambio, points out that humanity is hurtling towards destruction unless we have the collective wisdom to change course quickly.

This report analyzes fossil fuel financing from the world’s 60 largest commercial and investment banks — aggregating their leading roles in lending and underwriting of debt and equity issuances — and finds that these banks poured a total of $3.8 trillion into fossil fuels from 2016–2020.

Exploration de la situation sociale des personnes dites « électrosensibles », dont le corps et la santé souffrent des rayonnements des technologies sans fil. Dans cette situation, toutes les dimensions de l’existence sont profondément perturbées.

Today, the average global temperature has increased by more than 1°C compared to pre-industrial values (Figure 1-1); atmospheric CO2 concentrations have risen from 280 to more than 400 ppm. At the current pace of emissions, the carbon budget that is left for staying below the 2°C target of the Paris Agreement will be depleted in a few tens of years. For the 1.5°C target, this budget will be exhausted before the decade is out.

The growing threat of abrupt and irreversible climate changes must compel political and economic action on emissions.

La Croix-Rouge française remettra, à l’occasion de la COP 25 qui s’est ouverte lundi 2 décembre 2019 à Madrid, un rapport sur les conséquences des changements climatiques sur la santé, une problématique sur laquelle l’association est fortement engagée.
