Climate data from several leading agencies confirms that 2025 was the third hottest year ever recorded, with temperatures only marginally lower than those in 2023 and 2024. More than 70 countries broke monthly temperature records, and regions such as Central Asia, West Africa, the UK, and the Arctic experienced unprecedented heat.

The report highlights the severe impacts of extreme temperatures, including deadly heat waves, economic disruptions due to dried shipping routes, and significant agricultural losses. Experts attribute the ongoing rise in global temperatures to human emissions, with the current decade confirmed as the hottest on record.

In the mountains of central Tajikistan, a collapsed glacier rushes at 6 meters per second. The glacier collapse, we say it's surged, related and triggered by high temperatures. Tajikistan had the most abnormal temperatures in the world in 2025 at 3 degrees above average. But it wasn't an anomaly. Countries in Central Asia and West Africa soared past annual heat records, as did the UK and the Arctic. More than 70 countries across the world broke monthly temperature records, and all this data informed reports from several leading agencies, concluding 2025 was the third hottest year on record. But the top line isn't the full picture. 2025 was only a fraction of a degree below 2023 and 2024. Pull back, and you see a stark reality of temperature trends, driven by human emissions. Whenever we talk about climate, we talk about averaged weather, and we take the average over 20 years at least, 20 to 30 years. We certainly are in the hottest decade. Behind the graphs and trends, devastating conditions take Senegal at 45 degrees. When my 12-year-old comes home from school with no AC and no fan, she tells us, he's hot and thirsty. It's stressful, she says. It's demoralizing. Heat waves were the world's deadliest form of extreme weather in 2025. High temperatures hit economies, too. Dried-up shipping routes disrupted trade. And around the world, agriculture faced devastating losses. In a normal dry summer, when you think it's dried up, it's nothing like this. 2025 is now climate history, but just two weeks into 2026, the heat is unrelenting. Experts have calculated Australia's temperatures in the high 40s last week were made up to five times more likely by climate change. Jill English, CBC News, Toronto.
