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

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.

The world must rewild and restore an area the size of China to meet commitments on nature and the climate, says the UN, and the revival of ecosystems must be met with all the ambition of the space race. Existing conservation efforts are insufficient to prevent widespread biodiversity loss and ecosystem collapse, the global body has warned at the launch of the decade on ecosystem restoration, an urgent call for the large-scale revival of nature in farmlands, forests and other ecosystems.

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.
