The water south of Greenland has been cooling, so what causes that?

Real Climate

An AMOC weakening by 15 % thus cools the region at a rate of 0.15 x 10 14 W and according to model simulations can fully explain the observed cooling trend (2). Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces.

The AMOC is slowing, it’s stable, it’s slowing, no, yes, …

Real Climate

Of the 24 CMIP6 models, a full 23 underestimate the sea surface cooling in the ‘cold blob’ And most of the CMIP6 models even show a strengthening of the AMOC in the historic period, which past studies have shown to be linked to strong aerosol forcing in many of these models (e.g. So what is this whiplash about?

Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

Its a great question, but the warming effect from heat-trapping gases far outweighs the cooling effect from industrial aerosols. Over the last few decades, there has been an observed decrease in total planetary cloud cover , especially over the North Atlantic Ocean off the Northeast US coast.

A Sign of Things to Come? After Last Ice Age, Europe Cooled as the Planet Warmed

Yale E360

More than 8,000 years ago, as the planet thawed following the end of the last ice age, Northern Europe abruptly cooled. New research reveals that Arctic ice melt weakened a critical ocean current, leaving Europe in the cold, a finding with important implications for future climate change. Read more on E360 →

Unlike in years past, there is no longer any serious discrepancy between the records – which use multiple approaches for the ocean temperatures, the homogenization of the weather stations records, and interpolation. Southern Ocean trends. The least visited part of the ocean are the waters around Antarctica.

What is happening in the Atlantic Ocean to the AMOC?

Real Climate

The Atlantic meridional overturning circulation (AMOC) is a large-scale overturning motion of the entire Atlantic, from the Southern Ocean to the high north. Graph by Ruijian Gou. The AMOC is a big deal for climate. It moves around 15 million cubic meters of water per second (i.e. 15 Sverdrup). Take the IPCC reports.

How to Make Your Halloween More Eco-Friendly

Ocean Conservancy

However, for our ocean and the planet, the real fright comes from plastic waste. Plastic candy wrappers, plastic decorations and other plastic waste have serious impacts on our ocean and marine life. Love ocean content? Our ocean is counting on us to take a stand, and together—we can make a difference. We are too.
