Deciphering the ‘SPM AR6 WG1’ code

Real Climate

In my opinion the press conference on 9 August 2021 didn’t do justice to the vast effort that went into it. 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 CO2 problem in six easy steps (2022 Update)

Real Climate

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).

Why is future sea level rise still so uncertain?

Real Climate

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.

Summer Air Pollution Trends: Factors Affecting Air Quality

Breezometer

California's summer of 2021 has seen record-breaking wildfire outbreaks, surpassing 2020 by over 500 fire events by mid-July. Over the period of 2020 and 2021, California has also experienced its two largest wildfires ever , the Dixie and August Complex fires. Levels of Ground-level Ozone Pollution Can Increase in Summer.

Clauser-ology: Cloudy with a chance of meatballs

Clauser however takes that number, removes 80 and 20 W/m 2 for atmospheric absorption by ozone (!!) Unfortunately, this is the opposite of what has happened – cloud cover, albedo and reflected shortwave have all decreased over that time ( Fig 2a in Loeb et al, 2021). Clouding the picture So where does this leave us?

Viewpoint: Forty-three years of the environmental movement?

A Greener Life

Instead, environmentalists were mainly concerned about the ozone layer, nuclear meltdown and chemical industrial pollution, the erosion of biodiversity and population explosion. In June 1979, atmospheric carbon stood at 339ppm, just below the 350ppm level scientists believe to be safe. In 2021 the world emitted 36.4
