Environment and Climate Change Canada predicts that 2026 is likely to rank among the top four warmest years on record. A recent analysis of global temperatures on ClimateData.ca indicates a strong certainty that 2026 will be one of the hottest years ever documented. The primary driver behind the planet’s warming trend is the escalating carbon emissions resulting from the combustion of coal, oil, and gas. While human activities play a significant role in setting new temperature records, other factors also contribute.
The analysis attributes the recent unprecedented global temperatures partially to the intense El Niño event in 2023-2024, exacerbated by ongoing human-induced global warming. The projected global average temperature for this year is estimated to range between 1.35°C to 1.53°C above pre-industrial levels. There is a 12% probability of surpassing the critical 1.5°C threshold, which countries like Canada, signatories to the Paris Agreement, have committed to avoiding.
The Paris Agreement aims to limit global warming to below 2°C above pre-industrial levels while striving to constrain the temperature rise to 1.5°C. The ultimate objective is to achieve global net-zero emissions by 2050. Keeping global warming below 1.5°C significantly lowers the risks associated with heatwaves, droughts, wildfires, and extreme precipitation, as highlighted by the Intergovernmental Panel on Climate Change (IPCC).
The analysis from Canada emphasizes that exceeding 1.5°C in a particular year does not equate to failing the Paris Agreement’s objective, which is based on the average temperature over multiple decades. However, this forecast indicates a concerning trend in the planet’s trajectory. 2026 is anticipated to mark the 13th consecutive year where global temperatures surpass 1°C above pre-industrial levels. Global temperature changes are typically measured against the pre-industrial baseline from 1850 to 1900.
Aside from Environment and Climate Change Canada’s forecast, the nonprofit organization Berkeley Earth also anticipates another hot year in 2026. They project that 2026 will resemble the warmth of 2025, which ranked as the fourth-warmest year since 1850. Last year, 2025, was the third-warmest year following 2024 and 2023.
