In its latest State of the Global Climate report, @WMO shows that 2015–2025 were the hottest 11 years on record, with heat stress affecting people of all ages on every continent.
Workers are especially vulnerable: around one-third of the global workforce (1.2 billion people) is exposed to workplace heat risk each year.
Rising temperatures affect health in many ways, increasing fatigue, injuries, dehydration, kidney strain and mental stress. According to @Lancet Countdown data, heat-related deaths have surged by 63% since the 1990s.
As a driver of our warming world, climate change also amplifies public health risks such as vector- and water-borne diseases.
@WHO works closely with @WMO to address the impacts of climate change on health systems—including extreme heat—by strengthening health facility readiness to cope with higher temperatures.
@WHO calls on governments to ensure that heat early warning systems are tailored to the needs of the health sector and that climate information is integrated into health decision-making.
Every heat-related death is preventable.
