The image below, adapted from NOAA, shows ocean heat moving toward the Arctic along the path of the Gulf Stream on June 25, 2023, while sea surface temperatures on the map are as high as 32.6°C.
The danger is that, as El Niño strengthens and as ocean heat keeps entering the Arctic Ocean from the Atlantic Ocean and the Pacific Ocean, a huge amount of heat will abruptly be pushed into the Arctic Ocean.
This situation threatens to cause massive loss of Arctic sea ice over the coming months, with water in the Arctic Ocean heating up strongly due to loss of the latent heat buffer and loss of albedo.
This in turn threatens to trigger methane eruptions from the seafloor of the Arctic Ocean, a threat that has been described many times before, such as here, here and here.

In addition, there are further events and developments that could unfold and make things even worse.
The bar on the right depicts the threat, as discussed at the Extinction page.
In conclusion, the situation is dire and calls for support for a Climate Emergency Declaration.
