En 2024, pour la première fois, la température moyenne de la Terre a dépassé 1,5 °C par rapport aux niveaux préindustriels, un seuil critique dans la crise climatique. Dans le même temps, des conflits armés majeurs continuent de faire rage en Ukraine, à Gaza, au Soudan et ailleurs. Ce qui devient de plus en plus clair, c’est que la guerre doit désormais être comprise comme se déroulant dans le contexte de la crise climatique. La relation entre la guerre et le changement climatique est complexe. Voici trois raisons pour lesquelles la crise climatique doit remodeler notre façon de penser la guerre.

Earth’s average temperature rose more than 1.5°C above pre-industrial levels in 2024 for the first time – a critical threshold in the climate crisis. At the same time, major armed conflicts continue to rage in Ukraine, Gaza, Sudan and elsewhere. What should be increasingly clear is that war now needs to be understood as unfolding in the shadow of climate breakdown. The relationship between war and climate change is complex. But here are three reasons why the climate crisis must reshape how we think about war.

As authorities declared 2024 the hottest on record, a key private sector climate alliance, the Glasgow Financial Alliance for Net Zero (GFANZ) abandoned a requirement that members be aligned to the Paris agreement. That was followed by a network of net zero asset managers suspending work, and deleting from its website its statement of commitments that members must adopt, after BlackRock, the biggest of them all, quit its ranks.

Companies announce climate goals with great fanfare—but all too often, they eventually scale back or fail to implement those pledges. We asked Yale SOM’s Todd Cort how significant these reversals are and what should be done to encourage companies to keep making progress.

Hopes of the UK government meeting its domestic and international climate targets have “worsened” over the past year, according to the CCC.

Almost every country in the world has signed up to the Paris Agreement’s goal of keeping warming well-below 2C and pursuing efforts to limit it to 1.5C.

Without more legally binding and well-planned net-zero policies, the world is highly likely to miss key climate targets.

Hundreds of students and graduates vow not to work for ‘climate wreckers that insure those responsible for the climate crisis’

National climate pledges would collectively require 1.2 billion hectares (about 3 billion acres) of land, researchers have found in a new study, The Land Gap Report. More than half of this land is already currently used for something else. This demand for land will put pressure on ecosystems, Indigenous lands, small farmers and food security. Protecting existing forests and securing Indigenous and community land rights are more effective than carbon capture plans requiring land-use change, including reforestation.
