Global warming: excessive heat affects 70 percent of workers – ILO
More than 70 percent of the world's workforce faces potential health risks due to climate change, according to the latest report of the International Labour Organization (ILO), published on Monday. This staggering statistic underscores the pressing need to revamp existing occupational safety and health measures to adequately address the emerging threats posed by climate-related hazards.
“More than 70 per cent of our workers are exposed to excessive heat, at least excessive heat, at one point in their working lives. That's 2.4 billion workers globally,” out of a global workforce of 3,4 billion, said Manal Azzi, Senior Specialist on Occupational Safety and Health (ILO) at the report launch at the United Nations in Geneva.
Entitled “Ensuring safety and health at work in a changing climate,” the report states that climate change is already having a serious impact on the safety and health of workers in all regions of the world.
Workers, particularly those in the world's most impoverished regions, face heightened susceptibility to the perils of climate extremes like scorching heatwaves, prolonged droughts, raging wildfires, and devastating hurricanes, according to the ILO.
The share of global workers impacted by climate change hazards has increased by about 5 percentage points, to 70 percent, from 65 percent in the year 2000, the report said.
According to Ms. Azzi, “more than 22 million workers suffering from sicknesses and injuries related to exposure to excessive heat and these can range from injuries in transport, in traffic accidents due to bad night of sleep because it was excessively hot, to construction accidents, injuries, slips and falls related to the exposure to heat.”
The report notes that numerous health conditions in workers have been linked to climate change, including cancer, cardiovascular disease, respiratory illnesses, kidney disfunction and mental health conditions. The impact includes the 1.6 billion workers exposed to UV radiation, with more than 18,960 work-related deaths annually from nonmelanoma skin cancer.
“Nearly 20,000 workers are dying yearly because of these injuries in the workplace related to rising temperatures and to exposure to excessive heat, indoor and outdoor heat, and losing millions - over 2 million disability-adjusted years - are lost because of injuries and deaths related to heat,” said ILO’s specialist on occupational safety and health.
With increasing temperatures and higher humidity, more pesticides are used in the agriculture sector. According to the report, there are more than 870 million workers in agriculture that are likely to be exposed to pesticides, with more than 300,000 deaths attributed to pesticide poisoning annually.
“15,000 people die due to parasitic and vector borne diseases exposed to in the workplace,” noted Ms. Azzi. “Obviously, these include a lot of diseases like dengue, rabies and various diseases that are increasing in regions that we never used to see them before. Malaria has even increased and we're seeing it's shown in countries that it never used to be before.”
The ILO expert highlighted that “the key issues we face are not where it's known to be very hot for the longest period where people are very acclimatized. But it's the new regions where heat was never such an issue and has become an issue that we're facing some of the acute injuries that that we're seeing today,” explained Ms. Azzi. “So we do have a list of detailed policy examples, collective bargaining examples, but also awareness raising and training programs that deal with all of the hazards I mentioned from vector borne disease control to air pollution to pesticides.”
Ms. Azzi stressed that all these factors are interlinked and that the right tools need to be in place to measure the impact and to be able to work on recommendations.
A major meeting is planned for 2025 by the ILO with the participation of government, employer and worker representatives to provide policy guidance on climate hazards.

New data showing that rivers were at their lowest level for decades last year provides further evidence that the climate crisis is real and countries must act immediately to protect themselves from the increasing threat to communities and livelihoods, the UN World Meteorological Organization (WMO) said on Thursday.
The key findings from WMO’s State of Global Water Resources 2025 report covering the hydrological cycle and extreme events in the five-year period to last year:
Highlighting the long-term decline in the Earth’s freshwater storage and glacier melt, WMO Secretary-General Celeste Saulo explained that the planet’s water reserves used to act as a planetary “savings account” that absorbed the occasional dry season, avoiding a water crisis. “One of the central stories of the 2025 report is what is happening to that savings account? And the simple answer is that we are depleting it,” she told journalists in Geneva.
Groundwater reserves are equally stretched and have been in decline since 2014, WMO’s report states, with nearly two-thirds of monitored wells worldwide showing levels lower than the historical norm and indicating a shift “further toward deficit…not recovery”.
“At the same time, we are seeing more water-related disasters,” Ms. Saulo said, while also stressing that the currently strengthening El Niño “will increase the risk of drought in some areas, and flooding in others”.
Glaciers disappearing
In 2025, for the fourth consecutive year, every major glaciated region on Earth lost ice mass, leading to short-term hazards including floods and long-term water insecurity, according to WMO.
Responding to a question about whether the changing global water cycle might have contributed to the deadly Nepal-China flooding disaster, Ms. Saulo explained that melting ice and rock was just one factor in the chain of events that ultimately sent a massive and deadly wall of water and debris downstream on 26 August, killing at least 1,367 people.
“You asked if it could happen again? Absolutely; the problem in this region is that there’s 63,700 glaciers at the last count,” she told a Press Conference in Geneva. “Even if you’re looking with remote sensing with satellites at these glaciers, you might see some faults, you might see some slight shifting, that does not mean necessarily catastrophic collapse. So, in order to plan for this, it’s very, very difficult. But the international community is looking very hard at ways in which we can bring people together to solve some of these monitoring issues.”
Data indicates that glaciers shrank between 2023 and 2025 with cumulative losses of 1,400 gigatonnes of water – or about one third of annual fresh water needs.
Every major glacier region on Earth lost ice for the fourth consecutive year.
“All 19 glacier regions around the globe lost ice; in Central Asia, Iceland, the Russian Arctic and western Canada and the United States, it was among the three worst years on record,” said Wayne Jenkinson, WMO’s Director of Hydrology and Cryosphere.
Some regions with smaller glaciers such as Central Europe, the Caucasus, the western Canada and the United States may already have reached “peak water”, Mr. Jenkinson warned.
“After this point, the glacier gives less meltwater each year simply because there is less ice left to melt. That matters for every community downstream that relies on water during hot, dry summers,” he explained.
Narelle van der Wel, WMO’s Head of Cryosphere Monitoring, Predictions and Services, stressed that while some further glacier loss is unavoidable, the eventual scale of the decline is not predetermined.
“Some glacier loss is inevitable, but total loss of glaciers is not yet inevitable,” she said, pointing to emissions reductions as central to limiting future losses.
Preparing for moving baselines
The report does not attribute every observed change to climate change alone. WMO says pressure on water resources and natural variability also contribute.
Mr. Jenkinson said governments need to prepare for “moving baselines” as historical patterns become less reliable.
“The situation 30 years ago is not where we are today,” he said. Countries, he added, need to prepare “for those changes that have really already arrived”.
