Flux continu

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.

Energy firms have made record profits by increasing production of oil and gas, far from their promises of rolling back emissions

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.

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

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

The destruction of global forests slowed in 2021 but the vital climate goal of ending deforestation by 2030 will still be missed without urgent action, according to an assessment. The area razed in 2021 fell by 6.3% after progress in some countries, notably Indonesia. But almost 7m hectares were lost and the destruction of the most carbon- and biodiversity-rich tropical rainforests fell by only 3%. The CO2 emissions resulting from the lost trees were equivalent to the emissions of the entire European Union plus Japan.
