La vie secrète des arbres : la théorie s’effondre

L’idée est si émouvante qu’elle a conquis le public, Hollywood, et jusqu’aux plus hautes institutions  : les arbres communiqueraient via un réseau secret… Sauf que c’est faux. Les scientifiques ont...

Un monde a +3°C correspond a une France a +4°C qui continue a se réchauffer ensuite. Je remets le fil ci-dessous qui rend +concret cette valeur de +4°C a partir de l'exemple de l'été2022 qui sera un "été froid" dans cette France a +4°C. 4/ xitter.cf/cassouman40/status/166…
Christophe Cassou@cassouman4030 May 2023
Une France à +4°C. Le chiffre tourne depuis plusieurs jours en boucle, avec beaucoup de confusion. S’adapter à +4°C, ça veut dire quoi exactement? Et est-ce que c’est renoncer à limiter le réchauffement mondial sous les 2°C? Un 🧵 pour remettre le thermomètre en ordre (1/47)

Our study showing a very low absorption of CO2 by plants in 2023 was published today - Thanks to all co authors doi.org/10.1093/nsr/nwae367

Low latency carbon budget analysis reveals a large decline of the land carbon sink in 2023

This work reveals an unprecedented weakening of the land carbon sink in 2023 using low-latency atmospheric inversion, dynamic vegetation models, and AI-pow

🚨 Collapse of the land carbon sink in 2023 🚨 As the CO2 growth rate reached a record high at Mauna Loa, we set up a low-latency analysis of the carbon budget and found that plants and soils absorbed almost no CO2 last year @gcarbonproject @gpbalsamo arxiv.org/abs/2407.12447

A study of Fremont cottonwood trees during a record-breaking heatwave in Arizona documented the plants’ dependence on water to keep their cooling systems operating. Without water, leaves heated to the point of permanent damage. In PNAS: ow.ly/yIVG50TO72q
