Lower air temperatures are now causing rapid growth of Arctic sea area, which is sealing off the Arctic Ocean and this makes it more difficult for ocean heat to be transferred to the atmosphere, thus aggravating the danger that more ocean heat will reach sediments at the seafloor of the Arctic Ocean and will destabilize methane hydrates contained in sediments.
The methane danger is also illustrated by the image below, adapted from an image issued by NOAA October 2, 2025, showing hourly methane averages recorded at the Barrow Atmospheric Baseline Observatory (BRW), a NOAA facility located near Utqiaġvik (formerly Barrow), Alaska, at 71.32 degrees North.

Climate Emergency Declaration
UN secretary-general António Guterres recently spoke about the need for “a credible global response plan to get us on track” regarding the international goal of limiting the global temperature rise. “The science demands action, the law commands it,” Guterres said, in reference to a recent international court of justice ruling. “The economics compel it and people are calling for it.”
What could be added is that the situation is dire and unacceptably dangerous, and the precautionary principle necessitates rapid, comprehensive and effective action to reduce the damage and to improve the outlook, where needed in combination with a Climate Emergency Declaration, as described in posts such as this 2022 post and this one and as discussed in the Climate Plan group.
