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 References B.D.

A Nobel pursuit

Real Climate

Fortunately, Manabe recently wrote a retrospective on his early work in response to receiving the Crafoord prize in 2018. The key aspects were the inclusion of water vapour feedback as temperatures increased, and the use of ‘convective adjustment’ to maintain stability of the lower atmospheric column.

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.

Another Historic Climate Court Ruling in the Netherlands

Legal Planet

its district, appellate , and supreme courts decided in favor of Urgenda, an upstart environmental organization, ordering the government to more aggressively reduce greenhouse gas emissions. Environmental Protection Agency (2007) forced the EPA to regulate greenhouse gas emissions. Everyone produces greenhouse gases.

Major US and European labs join forces to tackle climate change

Physics World

It found that greenhouse-gas emissions emitted by the lab in 2018 was 223 800 tonnes of carbon-dioxide equivalent. The CERN particle-physics lab near Geneva, for example, uses 1.3 terawatt hours of electricity annually, which is enough to power 300 000 UK homes for a year. Eager to learn.
