2025: Record Greenhouse Gas Levels and Above-Average Cyclone Activity
Jamaica · Published Aug 11, 2026
The 36th annual 'State of the Climate' report reveals that 2025 saw record-high greenhouse gas concentrations, global sea levels, and ocean heat content. The year was among the three warmest on record, despite the absence of El Niño conditions. Tropical cyclone activity was above average, with 97 named storms globally, including five Category 5 storms. Hurricane Melissa became one of the strongest Atlantic hurricanes on record, with winds of 190 mph (306 km/h) and a central pressure of 892 hPa. The Arctic experienced its second-warmest year, while Antarctica recorded its warmest year since
Glaciers worldwide continued to lose ice for the 38th consecutive year.

Impact & Risks

The record-breaking greenhouse gas levels and rising global temperatures are accelerating climate change, leading to more extreme weather events. The increase in tropical cyclone activity, including five Category 5 storms, highlights the growing risks to coastal communities. Rising sea levels and melting glaciers are threatening low-lying areas and ecosystems. The Arctic and Antarctic regions are experiencing significant warming, with reduced sea ice and increased surface melt, which could have long-term impacts on global weather patterns and biodiversity.
