Union of Concerned Scientists

This report, issued by NOAA annually since 2006, was a much-anticipated event at the annual American Geophysical Union meeting because the implications matter far beyond the Arctic.

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. 2006), indicating a model bias toward a monostable AMOC.

Sea Level Rise is Already Threatening Communities

Union of Concerned Scientists

And since 2006, it has been even faster: as high as 4.2 The primary cause of accelerating sea level rise is human activity As people burn fossil fuels and emit heat-trapping gases like carbon dioxide, our atmosphere and our oceans warm up. As the ocean warms, it expands. That adds water to the oceans, which raises their level.

Sea level in the IPCC 6th assessment report (AR6)

Real Climate

During the most recent period analyzed, 2006-2018, it’s been rising at a rate of 3.7 However, on the level of basic physical reasoning, it is of course a no-brainer that warming will cause land-ice to melt (and melt faster as it gets hotter) and ocean waters to expand, so sea-level rise is the inevitable result.

Why is future sea level rise still so uncertain?

Real Climate

Meanwhile, note that the factors listed above involve the whole Earth system: the oceans, the cryosphere, the atmosphere, the solid earth and lithosphere, and a full range of scales, from the city block and shoreline, to ice dynamics that change over kilometers, to GRD footprints, to the whole global ocean. 2020) or Sadai et al.

49 Years of Advocating for Our Ocean

Ocean Conservancy

That’s almost five decades of working towards a clean, healthy, sustainable ocean. I am humbled when I think about all Ocean Conservancy has seen and accomplished since 1972. We’ve witnessed mind-blowing ocean discoveries, like new bioluminescent sharks and ancient fossils that illustrate what the ocean looked like eons ago.

More surprisingly, our research librarians found a lot on teaching of sustainability but nothing that really filled this gap.
