Oceans may start emitting ozone-depleting CFCs

Successful Green

As atmospheric concentrations of CFC-11 drop, the global ocean should become a source of the chemical by the middle of next century, a new MIT study predicts. The world’s oceans are a vast repository... The post Oceans may start emitting ozone-depleting CFCs appeared first on successful GREEN.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

There is no doubt that we have changed Earth’s climate through our activities on a broad range of aspects that includes consequences for the atmosphere, the oceans, snow, ice, Earth’s fauna and ecosystems. In addition, ozone depletion higher up in the stratosphere has caused a cooling high up in the atmosphere. mm increase every year.

2022 updates to model-observation comparisons

Real Climate

The key conclusions were that the internal variability, and treatment of ozone and aerosol forcings make material differences to the comparisons and that these need to be considered part of the structural uncertainty in the models.

How is Ocean Warming Impacting the Shipping Industry?

Ocean Conservancy

As deeply troubling reports continue to come in about ocean waters hitting historic hot temperatures, sectors like global shipping are trying to understand the consequences of a warmer ocean and what can be done to stop the heating. So, we’re seeing the ocean heat up, lose oxygen and get bigger. as a national policy leader.

Why is future sea level rise still so uncertain?

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.

A NOAA-STAR dataset is born…

The weighting varies a little between land and ocean, and as a function of topography or surface type (some model-observation comparisons take this into account, but a global uniform weighting is often good enough). But why should this be so? While these are important effects, they are often local.

The definitive CO2/CH4 comparison post

Real Climate

Methane emissions have a feedback on its own lifetime, serve as an ozone precursor, and reduce the production of sulphate and nitrate aerosols (and consequently indirect cloud-aerosol effects), all of which amplify its net warming effect to about 1.2 W/m<sup>2</sup> (to about 60% of the CO 2 effect since 1750).
