Arctic ocean warming

New research from Yale oceanographers has revealed a build-up of heat in the deeper levels of the Arctic Ocean that may trigger a massive melting of the sea ice above.

The research team analysed temperature data on the Canada Basin taken over the last 30 years, and found that the amount of heat in the warmest part of the water had effectively doubled in the period 1987 to 2017.

This 30-year doubling (growth rate of between 2-3% per annum) coincides with the Great Acceleration of the impact of so many human activities at a planetary scale. In this case it is the hydrosphere and the cryosphere that are being impacted, but the connection to what is happening to the global atmosphere is obvious. The parallel increases in greenhouse gas emissions arising from fossil fuel use has many effects, just as has the massive addition of plastics to the natural environment and many other synthetic chemicals . As humans strive for wealth and accelerated consumption of technologically created goods and services, many UNINTENDED CONSEQUENCES  tend to follow. A small number of scientists reveal these but the rush for ‘development’ understood as ever-increasing GDP growth, continues to accelerate as human population adds an extra 1 billion humans to an overloaded planet in the next 14 or so years.

Coastal erosion in the Arctic a new concern – report on new research.
