Climate shocks are becoming an economic bill the world can no longer ignore

TLE Desk: Climate change is increasingly moving from an environmental problem to an economic one, with extreme weather disrupting food production, infrastructure and livelihoods while developing countries struggle to secure the finance needed to adapt.

The warning comes as governments and investors gather ahead of COP31, which will be held in Antalya, Türkiye, from November 9 to 20. This year’s negotiations are expected to focus heavily on turning existing climate commitments into investment and measurable action.

The latest temperature data underline the scale of the challenge. August 2026 was the joint hottest August ever recorded, with global average surface air temperature reaching 1.65°C above the estimated pre-industrial level, according to the Copernicus Climate Change Service. It was the first month since November 2025 to exceed 1.5°C.

The economic consequences are already being felt. A developing El Niño is threatening droughts, heatwaves and wildfires across parts of Asia, with agriculture and fisheries particularly exposed. Analysts cited by AP estimate that food prices could rise by more than 15 per cent if the effects become severe, while the UN has warned that tens of millions more people could face acute food insecurity.

For poorer countries, the problem is not simply the size of the damage but how to pay for it. Nepal’s prime minister told the United Nations this month that a recent glacier-related flood had caused recovery and reconstruction needs estimated at around 10 per cent of GDP. He called for grants rather than additional debt to help vulnerable countries rebuild after climate disasters.

The same financing concern is being raised across the developing world. Bangladesh has called for stronger international action on climate justice, climate finance and adaptation, arguing that countries contributing relatively little to global emissions are facing some of the most severe consequences of climate change.

The pressure is also reshaping the agenda for COP31. Turkey’s COP31 presidency has proposed targets including increasing electricity’s share of energy consumption to 35 per cent by 2035, cutting energy-use intensity in buildings by at least 25 per cent, and increasing the global circular-material-use rate to 15 per cent. The presidency estimates that these measures could have the potential to reduce global emissions by 8.5–10 gigatonnes of CO₂ by 2035.

Finance is at the centre of the debate. UN Secretary-General António Guterres has called for global climate finance to reach $1.3 trillion a year by 2035, including at least $300 billion annually for developing countries. The argument is increasingly economic as much as environmental: without investment in resilient infrastructure, clean energy and adaptation, climate disasters can translate into higher public debt, weaker growth and lost livelihoods.

The challenge is particularly acute because governments are already dealing with high borrowing costs, energy insecurity and competing development priorities. Climate investment therefore has to compete for capital with roads, healthcare, education, industrial development and debt servicing.

That makes climate finance one of the defining economic questions heading into COP31. The issue is no longer simply how much the world should spend to reduce emissions, but who pays for the economic damage already being experienced and who finances the infrastructure needed to withstand what comes next.

For farmers watching rainfall, families living beside rivers and governments rebuilding after floods, the climate debate is no longer a distant discussion about 2050. It is increasingly a question of today’s income, tomorrow’s food prices and the cost of keeping an economy functioning.
