Last month, 44 climate scientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. Picture Quebec City in Canada and London in the UK.

The only region of cooling is the northern Atlantic, where climate models have long predicted just that due to a slowing of the Atlantic Ocean overturning circulation. The heating of the global ocean has been going on at a steady rate of nine zeta Joules per year for decades , which is 15 times the worldwide primary energy consumption.

As climate scientists we tend to look at the IPCC reports a little differently than the general public might. Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) Figure SPM 8.

In this, he is in violent agreement with Isaac Held, his colleague at GFDL, and indeed most climate scientists. Manabe’s subsequent work led to the development of the GFDL GCM, initially just including the atmosphere, but eventually with an ocean, and then the transient results shown in Manabe and Stouffer (1993).

As the material breaks down over time, it releases vast quantities of microscopic particles – which due to their small size and low density, can be transported across the globe by winds and ocean currents. Altitude matters. However, exactly how microplastics are distributed in the atmosphere is not well known.

For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. Several floating ice shelves – the massive slabs of ice that push back grounded ice from flowing into the ocean – have catastrophically broken up in a matter of days because of such melting.

Presumably Dagsvik and Moen are used to this kind of model, but they seem to be inexperienced with the models used for weather and climate, which on the other hand are based on the laws of physics. Furthermore, the volume of the oceans increases from the melting of land ice.
