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.

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.

California’s Thirsty Future: The Role of Vapor Pressure Deficit in Our Changing Climate and Drought

Union of Concerned Scientists

The increase regional VPD is mostly attributed to human-cause climate change (68%) and the rest (32%) is attributed to variations in the atmospheric circulation. High atmospheric “thirst” over multiple seasons or years can lead to drought conditions as vegetation dries out, and water flow in streams and rivers decreases.

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.

Should the official Atlantic hurricane season be lengthened?

Real Climate

But this also raises other questions: 1) Can we expect the season to continue to lengthen as global warming from increasing concentration of globally well mixed greenhouse gas (GWM-GHG) continues to warm the Atlantic SSTs? In particular, they don’t just respond to SST changes, but also how the atmosphere changes as the SSTs change.
