blue whale vocalizations dropped by almost 40 percent, according to the study, with populations of krill and anchovy collapsing. "When you really break it down, it’s like trying to sing while you're starving," Ryan explained. "They were spending all their time just trying to find food."

Rising temperatures are causing water to evaporate and driving humans to extract more groundwater, which is moving freshwater from the land to the seas and creating a "continental drying" trend..

Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say

For more than three decades, Brazilian climate scientist Carlos Nobre has warned that deforestation of the Amazon could push this globally important ecosystem past the point of no return. Working first at Brazil’s National Institute for Space Research and more recently at the University of São Paulo, he is a global authority on tropical forests and how they could be restored.

Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend

Major study finds world's most productive farming regions are especially vulnerable to rising temperatures, and face steep declines in agricultural output this century.

Even if agricultural practices adapt in response to higher temperatures, five of the world's six main staple crops will suffer severe losses due to climate change. Global corn yields are projected to fall by about 12 or 28 per cent by the end of the century

Breaching threshold would ramp up catastrophic weather events, further increasing human suffering

There’s frustration among researchers that falling pH levels in seas around the globe are not being taken seriously enough, and that until the buildup of CO2 is addressed, the consequences for marine life will be devastating

Lenton, the founding director of the Global Systems Institute at the University of Exeter, was the lead author of the 2008 paper that formally introduced the idea of tipping points in the Earth’s climate system.

Societies increasingly rely on scientists to guide decisions in times of uncertainty, from pandemic outbreaks to the rise of artificial intelligence. Addressing climate change is no different. For governments wanting to introduce ambitious climate policies, public trust in climate scientists is pivotal, because it can determine whether voters support or resist those efforts.

Do civilizations have tipping points that determine their rise and fall? Untangling how and why civilizations fall could, in theory, help humanity avoid a future calamitous collapse. “The reason why complex societies disintegrate is of vital importance to every member of one, and today that includes nearly the entire world population,” Tainter wrote. “Whether or not collapse was the most outstanding event of ancient history, few would care for it to become the most significant event of the present era.”

https://www.ucs.org/resources/1992-world-scientists-warning-humanity - Some 1,700 of the world's leading scientists, including the majority of Nobel laureates in the sciences, issued this appeal in November 1992. The World Scientists' Warning to Humanity was written and spearheaded by the late Henry Kendall, former chair of UCS's board of directors.

Il y a vingt-cinq ans, l'Union of Concerned Scientists et plus de 1700 scientifiques indépendants, dont la majorité des lauréats scientifiques du prix Nobel d’alors, ont scellé l'Avertissement des scientifiques du monde à l'humanité de 1992 (voir le texte en annexe S1). Ces scientifiques s’adressaient à l'humanité afin d’endiguer la destruction de l'environnement et avertissaient « Si nous voulons éviter une misère humaine à grande échelle, il est indispensable d’assurer un changement profond de notre gestion des ressources et de la vie sur Terre ».
