In a World at War, the Biggest Loser Is Climate |
Last week, the British government quietly informed the United Nation's Green Climate Fund that it would halve the contribution it pledged just two years ago, not because the climate crisis has eased, but because it is spending more on weapons. The move was framed as a "hugely difficult decision," not ideological, and necessary to deliver what United Kingdom Foreign Minister Yvette Cooper called "the biggest increase in defence spending since the Cold War." The planet, apparently, can wait.
The UK's retreat from climate finance is not some isolated budget decision. It is part of a choice being made across the Global North: to rearm, to retreat from development commitments, and to leave the countries least responsible for the climate crisis to deal with its worst consequences on their own.
Global military expenditure reached $2.887 trillion in 2025, pushing the global military burden to 2.5% of GDP, its highest level since 2009. Europe's alone surged 14% to $864 billion, the highest level ever recorded for the continent. Meanwhile, the UN's own analysis found that reinvesting just 15% of global military spending, roughly $387 billion, would be more than enough to cover the annual costs of climate adaptation in developing countries. The money exists. The will does not.
More conflict and more military spending will only deepen the crisis and make millions more people vulnerable to it.
The UK's Green Climate Fund cut does not happen in a vacuum; the US has refused to deliver any further money to the GCF under President Donald Trump and has also given up its seat on the fund's board. According to the Organisation for Economic Co-operation and Development, international development assistance fell by 23.1% in 2025, the steepest annual decline on record, with the United States slashing its aid budget by 57%, Germany by 17%, and France and the UK by 11% each.
The countries that industrialized on the back of fossil fuels, with the highest historical emissions and the highest per capita carbon footprints, are the ones least bothered by any of this.
And yet for the Global South, the signal being sent today is unmistakable: The nations least responsible for the climate catastrophe bearing down on them will have to bear its consequences largely alone, watching the world burn while the architects of that burning pivot to missiles and military budgets. The prospect of just and equitable climate finance from the developed world is beginning to look not merely uncertain, but futile.
The same wars that are killing climate finance are generating record profits elsewhere. Oil and gas companies' profits are soaring as the Iran conflict continues. Chevron, Shell, BP, ConocoPhillips, Exxon, and TotalEnergies are projected to make $2,967 a second in........
