CMIP6: Not-so-sudden stratospheric cooling

Real Climate

So SSU me Like MSU trends, these records reflected a weighted average of atmospheric temperatures, and the three SSU channels progressively weight higher levels in the stratosphere, roughly centered on 30km, 40km and 45km above the surface but with quite a bit of overlap. Thompson et al. We are using the NOAA-STAR version 3.0

Some new CMIP6 MSU comparisons

Real Climate

Since this is a somewhat differently designed ensemble, I’ll plot that similarly (45 simulations), and note too that these are global means, again, for the corrected-TMT product (for the historical and SSP2-45 scenarios after 2014). Tsigaridis, L.S. Nazarenko, S.E. Bauer, and D.T.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

Lake Erie’s Failed Algae Strategy Hurts Poor Communities the Most

Circle of Blue

Their collective trauma dates back to August 2, 2014, when she and half a million other Toledoans woke to alarming news: the water coming out of their taps was toxic. After the 2014 Toledo water crisis, the binational International Joint Commission tried to put a price tag on the event. Carl Ganter, Circle of Blue. September 20, 2022

Scanning the cosmos for signs of alien technology

Physics World

Exoplanets come in many sizes and types, from terrestrial rocky worlds to super-Earths, Neptune-like exoplanets, hot Jupiters and more (see “Planets galore” April 2014 ). The atmospheres of a few Jupiter-sized exoplanets have already been scoured in this way, and the JWST should allow similar searches for smaller, Earth-like exoplanets.

Oil Refineries: A Deadly Industry

Union of Concerned Scientists

One good example of the nexus between global warming and local pollution is ground-level ozone. Because of the complexity of atmospheric chemistry, there may be unexpected links between global warming and local pollution, so policies must address both kinds of pollution keeping in mind the latest science on how they are connected.

July 2017 Updates to the Climate Case Charts

Law Columbia

A magistrate judge in the federal district court for the District of Oregon granted motions by three trade groups to withdraw from the lawsuit seeking to hold the United States liable for its actions and inaction leading to the accumulation of greenhouse gases in the atmosphere.
