November 6, 2025 Climate and environment
In 2025, the planet continues to break temperature records. According to data released Thursday by the World Meteorological Organization (WMO), this year will likely be the second or third warmest on record, with the last 11 years—2015 to 2025—already recognized as the hottest in 176 years.
Air temperature
The average surface temperature from January to August 2025 was 1.42 degrees Celsius above pre-industrial levels. This is slightly lower than in 2024, when the El Niño effect was observed, but overall, the heat wave is not abating.
From June 2023 to August 2025, almost every month set temperature records—except February 2025. Scientists attribute this not only to natural cycles, but also to increased aerosol production and other factors. anthropological factors, increasing warming.
Oceans and sea level
The oceans continue to accumulate heat: more than 90 percent of the excess energy caused by greenhouse gases goes there. This leads to destruction of marine ecosystems, increased storms and accelerated ice melting.
Sea levels are rising at an ever-increasing rate: while in the 1990s they rose by 2.1 mm per year, they are now rising by 4.1 mm. A record level was recorded in 2024, but this year, it has temporarily dropped due to natural factors.
Ice area and glaciers
The area of Arctic ice after this winter has reached the lowest level In the entire history of satellite observations, the situation in Antarctica is also alarming: in 2025, the third-highest ice loss in recorded history was recorded.
Global glaciers are losing mass for the third year in a row. They are estimated to have lost 450 gigatons of ice in 2023/2024, equivalent to a sea level rise of 1.2 mm.
Greenhouse gases
Concentrations of carbon dioxide, methane and nitrous oxide in the atmosphere reached record levels in 2024 and continue to growCO₂ levels have risen by 53 percent compared to pre-industrial levels, making the single-year increase the largest on record.
Extreme events
This year has brought devastating floods in Africa and Asia, wildfires in Europe and North America, and deadly tropical cyclones. These events have impacted economies, food security, and led to mass displacement.
Energy and climate services
The 2024 heat wave caused a spike demand for electricity – four percent above average, and in some regions, such as Central and Southern Africa, nearly 30 percent higher. This highlights the need to consider climate data in energy planning.
National meteorological services are increasingly involved in climate policymaking. Now, almost two-thirds of them provide not only basic forecasts but also in-depth analytical reports. Five years ago, only 35 percent did so.
Early warning systems
Since 2015, the number of countries that have implemented multifactorial early warning systems, increased from 56 to 119. However, 40 percent of countries still lack such systems. Accelerating progress is especially important in least developed countries and island territories, the WMO notes.
