Chart of the Day: Ocean temperatures were warmest on record for October, including in some Australian waters

Resumen detallado

Globally sea-surface temperatures have never been recorded so warm for any October, with the monster El Nino a factor.

Sea-surface temperatures set fresh record highs globally for any October, with some regions around the Australian coast registering record highs too, according to new data from the US analysed by Australia’s Bureau of Meteorology.

The long-run background warming from climate change has lately been supplemented by the giant El Niño event in the Pacific, with further intensification of the latter expected by BoM and other global agencies.

The sea-surface temperatures have been rising for decades, an outcome that is not surprising to scientists given just over 90% of the excess heat being trapped in our biosphere from higher concentrations of greenhouse gases ends up in the oceans.

Here’s how BoM assesses those warming sea temperatures using data from the US’s National Oceanic and Atmospheric Administration:
