Record Ocean Temperatures in 2025 w/ distinguished scholar at The National Center for Atmospheric Research in Boulder, Colorado, Kevin Trenberth: 12th January, 2026

2025 saw the highest rise in ocean temperatures since modern measurements began, marking a worrying increase in the pace of the climate crisis. Ocean temperature measurements are one of the most accurate measures of climate change, and have significant impacts on multiple ecological factors, including weather.

To discuss rising ocean temperatures and what they mean for the world, News Director Castor spoke to one of the authors on the paper discussing the findings, distinguished scholar at the National Center for Atmospheric Research in Boulder, Colorado, and honorary faculty member at the Department of Physics at the University of Auckland, Kevin Trenberth, about rising ocean temperatures and the potential ramifications.
