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

But with estimates suggesting that sea level rise will affect more than one billion people around the world in the next 25 years, this is one member of the dysfunctional climate change family that shouldn’t be ignored. And since 2006, it has been even faster: as high as 4.2 Why is this? As the ocean warms, it expands.

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. Li, "Past and Future Hurricane Intensity Change along the U.S.

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.

Land-use, climate change, and policy – Opportunities to act locally while thinking globally

HumanNature

Land-Use and Climate Change Growing urban populations are accelerating land-use change (LUC) around the globe, as witnessed in the Front Range of Colorado 1–3. In recent history, we have witnessed LUC exacerbating climate change due to disturbed soils, development of greenhouse gas (GHG) producing land uses, and more 4.
