On Tuesday, the U.S. National Oceanic and Atmospheric Administration released its annual Arctic Report Card – a collection of concise, peer-reviewed summaries that aims to capture how the climate is behaving at Earth’s northern extremes, including in Canada.
A well-known feature of climate change is that the Arctic is warming several times faster than the rest of the planet on average. This year’s Arctic Report Card confirms that the region has just logged its warmest year since 1900 – a new extreme that follows the general trend.
Other broken records in 2025 include: the lowest maximum sea ice extent in the 47-year satellite record, the warmest autumn on record and the highest annual precipitation since tracking began.
