2019 Atmosphere Carbon Dioxide 
Union of Concerned Scientists
MARCH 7, 2023
One study found that human-caused climate change made the 2019 European heatwave as much as 100 times more likely to occur. Scientists have long known that burning fossil fuels is the primary cause of the increase in atmospheric carbon dioxide concentrations, but now they can identify the specific sources.

2019 ) gives a good overview of Manabe’s particular philosophy of climate modeling which was very much focused on getting things to work, and not worrying too much about the details. The basic issue stems from the different timescales of the ocean and atmosphere. Manabe’s Climate Modeling. That paper ( Manabe et al.,

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).

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.

The primary cause of accelerating sea level rise is human activity As people burn fossil fuels and emit heat-trapping gases like carbon dioxide, our atmosphere and our oceans warm up. A 2019 UCS analysis, Underwater , found that Charleston can expect roughly 500 homes to flood on a chronic basis by 2035.

The “for one year” part is crucial: stratospheric aerosols stay in the atmosphere roughly a year, so one gram offsets the heating effect of one ton only for the first year after the ton is emitted. After that, the sulfur is gone but the CO 2 is still there and heating.)

What’s most remarkable is that the decision calls for a 45% reduction of carbon dioxide (CO 2 ) emissions–of not only its own but also those of its customers–within less than a decade. This is therefore what Shell must do (oddly enough relative to 2019) in order to act in line with its own “policy, policy intentions and ambitions.”.
