Arctic Report Card 2024: How Did the Region Fare? Ask the Caribou

Union of Concerned Scientists

For the first time, the Arctic Report Card assessed that the Arctic is faltering as a reliable area for storing carbon away from the atmosphere ( Natalie et al., It was its first failing grade after thousands of years holding onto more carbon than released to the atmosphere. in Arc2024 ). Methane releases were sustained as well.

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. This loss of land ice has been the dominant contributor to sea level rise since 2006.

Should the official Atlantic hurricane season be lengthened?

Real Climate

The difference is due largely to the differences in the regional atmospheric response that occurs in concert with the SST warming. In particular, they don’t just respond to SST changes, but also how the atmosphere changes as the SSTs change. The key to understanding this lies in understanding what tropical storms respond to.

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.
