Global climate leaders and meteorological authorities declared on November 9, 2026, that relentless greenhouse gas emissions and an “off-the-charts” El Niño event have officially transformed the climate emergency into a global health crisis of pandemic proportions.
Speaking at a joint World Meteorological Organisation (WMO) press conference convened during COP31 in Antalya, representatives from the United Nations and global health philanthropies warned that rising temperatures, ocean heating, and unprecedented drought are severely straining health systems, threatening food security, and driving millions of premature deaths worldwide.
WMO Secretary-General Celeste Saulo’s State of the Climate Update 2026 confirms that global temperatures have breached critical thresholds.
From January to September 2026, the global average temperature stood approximately 1.47 °C above pre-industrial baselines. The update confirms that the past 12 years are the warmest 12-year period ever recorded, and that the past four years—including 2026—rank among the four hottest years in human history.
WMO forecasts indicate that sea-surface temperatures in the Tropical Pacific—the epicentre of El Niño—are expected to reach nearly four times the standard 0.5 °C El Niño threshold between November 2026 and January 2027.
Secretary-General Saulo emphasised that because El Niño traditionally exerts its maximum influence on atmospheric temperatures in the year after its initial development, 2027 is projected to break global temperature records again, following the record set during the 2024 El Niño cycle.
Beyond rising air temperatures, ocean heat reached its highest level on record for the tenth consecutive year, while global sea levels hit new highs, compounding storm surge and flooding risks for roughly 900 million residents living along low-lying coastal zones worldwide.
Extreme weather events intensified across every region in 2026, including high-mountain disasters in China and Nepal that threatened downstream communities, devastating floods in parts of South America and Africa, and severe droughts across Central America, Asia, and the Pacific.
Heat mortality, drought, and maternal vulnerability
UN Climate Change Executive Secretary Simon Stiell framed the environmental indicators in stark medical terms, warning that climate destruction is directly destabilising human physiology and national health infrastructures.
He highlighted severe health impacts documented during the northern summer of 2026, where extreme heat waves led to an estimated 50,000 excess deaths across Europe alongside dangerous heat spikes across India, Pakistan, and North America.
“The climate crisis is now a global health crisis of pandemic proportions. From toxic pollution to extreme heat, and climate disasters slamming through health systems and infrastructure, the root cause is humanity still burning colossal amounts of coal, oil and gas, and destroying forests,” said Stiell.
Data presented by Wellcome Director of Climate and Health, Alan Dangour, underscored the systemic scale of mortality and environmental health disruption:
Air Pollution and Thermal Mortality: Combined fossil-fuel air pollution and extreme heat currently claim over 3 million lives each year globally.
Agricultural and Sanitation Strain: Extreme drought affected nearly 52% of the world’s land surface for at least one month in 2025—the second-highest level ever recorded—depleting groundwater reserves and disrupting sanitation and food security.
Maternal and Newborn Risks: Citing results from a new global survey of 1,000 maternal health professionals, Stiell and Dangour flagged severe physiological threats to pregnant women and newborns caused by extreme thermal exposure. In response, partners at Pre-COP31 in Fiji launched a global call to action to establish medical guidelines, heat response plans, and surveillance data targeting maternal health.
The “electric or shock” economic choice
To address the structural reforms needed to curb the crisis, the UN Climate Change Executive Secretary gave national delegations a clear economic framing: “electric or shock.” Stiell argued that accelerating clean electrification is both an economic imperative and a primary public health intervention, relieving health budgets and households burdened by volatile fossil-fuel prices.
To address chronic underfunding in public health adaptation, philanthropic organisations reported significant progress under the Climate & Health Funders Coalition, originally established at COP30 in Belém with an initial joint commitment of $300 million across more than 35 funding organisations.
First-Year Grant Deployments: The coalition has officially awarded over $ 225 million in its first year of operation, supporting targeted interventions in extreme heat management, air pollution reduction, climate-sensitive infectious disease surveillance, and health data systems.
Expanded Capital Commitments: Over the past year, the coalition secured an additional $150 million in new financial pledges from existing and incoming donors.
Preventative Health Dividends: Global health data indicate that clean air initiatives have already prevented over 300,000 deaths annually across at least 77 countries that reduced fossil-fuel air pollution over the past decade.
Despite grim temperature projections, WMO Secretary-General Saulo emphasised that targeted adaptation measures are delivering measurable protections against extreme weather events. A key success has been the rapid global expansion of multi-hazard early warning systems.
Secretary-General Saulo stressed that maintaining and extending these life-saving networks requires continuous investment in global meteorological observation networks, warning that decision-makers “cannot afford to fly blind” as climate impacts accelerate.
Closing the joint press conference in Antalya, Wellcome Director Alan Dangour called for a fundamental shift in international climate negotiations, urging governments to evaluate policy progress through human health outcomes rather than abstract environmental targets alone.
“We must change course and put the health and wellbeing of people at the heart of our response to climate change – measuring success not through emissions targets or degrees Celsius but by lives saved and health outcomes improved. The state of the climate is now, in reality, the biggest indicator of the state of human health,” said Alan Dangour.
As COP31 negotiations proceed under the co-guidance of Türkiye and Australia, delegates face growing pressure from international scientific and health bodies to integrate public health protections, clean energy electrification, and dedicated adaptation funding directly into final international agreements.
