Global temperature leaped more than 0.4°C (0.7°F) during the past two years, the 12-month average peaking in August 2024 at +1.6°C relative to the temperature at the beginning of last century (the 1880-1920 average). This temperature jump was spurred by one of the periodic tropical El Niño warming events, but many Earth scientists were baffled by the magnitude of the global warming, which was twice as large as expected for the weak 2023-2024 El Niño.

UN Secretary-General António Guterres called for making 2025 “a new beginning” in his message for the New Year, issued on Monday.

Crippling heat is everywhere. Billions of people around the world are wilting under increasingly severe heatwaves driven largely by a fossil-fuel charged, human-induced climate crisis. More than 70 per cent of the global workforce – 2.4 billion people – are now at high risk of extreme heat. The most vulnerable communities are hit hardest.

Communiquer sur les changements climatiques, c’est éduquer les publics et les inciter à agir pour lutter contre la crise climatique. Tout le monde peut jouer un rôle en faisant entendre sa voix, en partageant des solutions et en plaidant pour le changement – en s’appuyant sur des expériences, des contextes culturels et des valeurs sous-jacentes différents. Si vous créez un produit de communication – une vidéo, un podcast, un article écrit ou un graphique sur les changements climatiques – gardez à l’esprit les conseils suivants pour en faire un contenu utile, efficace et fiable.

Finance needs of developing countries now 10-18 times as big as international public finance flows Growing gap results from rising adaptation needs and faltering adaptation finance Failure to enhance adaptation has huge implications for losses and damages

La campagne Agissons (ActNow) est un appel des Nations Unies à une action citoyenne contre les changements climatiques et pour la durabilité.

Les combustibles fossiles, à savoir le charbon, le pétrole et le gaz, sont de loin les plus grands contributeurs au changement climatique mondial ; ils sont responsables de plus de 75 % des émissions mondiales de gaz à effet de serre et de près de 90 % de toutes les émissions de dioxyde de carbone. Les émissions de gaz à effet de serre enveloppant la Terre, elles retiennent la chaleur du soleil. Cela entraîne un réchauffement climatique et un changement climatique. Le monde se réchauffe désormais à une vitesse jamais observée dans l’histoire documentée. Au fil du temps, les températures plus élevées entraînent des variations climatiques et déstabilisent l’équilibre habituel de la nature. Cette situation pose de nombreux risques pour les êtres humains et toute autre forme de vie sur Terre.

Three former UN climate heads say gap between government promises and actions will change environment irreversibly

Only 17.4 per cent of 2019’s e-waste was collected and recycled. This means that gold, silver, copper, platinum, and other high-value, recoverable materials conservatively valued at US $57 billion — a sum greater than the Gross Domestic Product of most countries — were mostly dumped or burned rather than being collected for treatment and reuse.

On 28 February, the Intergovernmental Panel on Climate Change (IPCC), a United Nations body solely dedicated to looking at the science behind climate change, will release a major report on the impacts of the climate crisis and why it is imperative that we act now to address the growing risks. The report, which focuses on Impacts, Adaptation and Vulnerability, is expected to detail how climate impacts are already wreaking havoc in every part of the world and how, without much bolder action, more lives will be lost and more livelihoods destroyed. The report will look at challenges and solutions for addressing these risks and minimizing vulnerability unique to the world’s regions, cities and other habitats.
