The Facts
- The 10th Lancet Countdown report says climate-related health harms have outpaced global action.
- Researchers called on the WHO and UN to recognize climate change as a global health emergency.
- India lost an estimated $174 billion in potential worker earnings from heat in 2025.
- India’s estimated 2025 heat-related earnings loss equaled 4.2% of GDP.
- People in India faced more than 2,600 annual hours of moderate-or-higher heat-stress risk during 2016-2025.
- Half of heatwave days experienced in India during 2016-2025 were attributable to climate change.
- The report identifies rising infectious-disease risks and air-pollution-related deaths as health concerns in India.
Context
What did the researchers ask the WHO to do?
They proposed that the WHO create an instrument to formally recognize climate change as a global health emergency and coordinate responses, with health considered in climate targets and funding. Hindustan Times EL PAÍS
How does heat affect workers in India?
The report estimates that heat reduced potential work capacity in India, contributing to 193 billion potential labour hours lost annually and $174 billion in potential earnings losses in 2025. Hindustan Times Indian Express
What global heat toll did the report estimate?
The report estimated that extreme heat was linked to 710,000 deaths worldwide in 2023, with more than 70% attributed to human-caused climate change. Independent NDTV MoneyControl
Where Left and Right agree, and where they split
- Where Left and Right agree
- India's heat losses — $174 billion in 2025 earnings, 4.2% of GDP — are real and substantial, and harm is accelerating faster than the global response.
- Where Left and Right split
- The left and the right split on whether an emergency declaration or economic capacity unlocks India's climate protections first.
- Why they won’t converge
- The split is about trust in international mechanisms: one side expects a formal WHO/UN emergency declaration to convert voluntary pledges into binding action, the other doubts such declarations after Paris-era commitments preceded worsening harm.
How left and right read it
Heat is already a wage cut, and it lands hardest on workers with no cushion, because India's estimated $174 billion in lost earnings in 2025 — 4.2% of GDP — came out of people working through more than 2,600 annual hours of heat stress, half of recent heatwave days attributable to climate change. Harm is outrunning response. So name it an emergency, and build the heat, disease and pollution protections that follow.
“The impact of climate change on human health is now outstripping international action, prompting experts to demand that the crisis be officially declared a global health emergency.” — The Independent
A country losing 4.2% of GDP to heat — $174 billion in worker earnings in 2025 — needs the wealth to cool workplaces, treat infectious disease and clean its air, because poverty buys none of that. Yet the harms accelerated after the Paris pact took effect while action lagged, so before the WHO and UN are handed emergency standing: what did the last round of promises actually buy India?
“The experts have cautioned that some health harms of climate change grew faster during 2016-25 since the Paris climate pact came into force than in the previous decade, 2004-15, but actions to curb global warming have failed to keep pace.” — The Telegraph
The $174 billion lost to heat is real money. The fight is over whether a label or built-up wealth gets it back first.
