Deciphering the ‘SPM AR6 WG1’ code

Real Climate

The main report is quite impressive (see earlier posts here , here , here , and here ) but the press conference didn’t come across as being focused and well-prepared. Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans.

The CO2 problem in six easy steps (2022 Update)

Real Climate

And so, here is a mildly updated and referenced version that should be a little more useful. Because the oceans take time to warm up, we are not yet there (so far we have experienced 1.2ºC), and so the remaining ~0.8ºC is ‘in the pipeline’ if we keep concentrations constant (equivalent to an immediate ~70% cut in emissions).

To register, visit the Academy Town Square page here. Ozone smog pollution reached unhealthy levels on twenty days. With ocean temperatures over 90°F off the Florida coast, Carl strengthened from a Category-1 with 80-mph winds to a Category-5 with 160-mph winds, in only 36 hours. The event is free and available on Zoom.

Environmental Law: Government and Public Policy Towards the Environment

Environmental Science

As we will explain in the next section, it covers many areas, all with the same purpose already described here. Chlorofluorocarbons (CFCs) : A group of inert chemical used in many industrial and everyday processes such as our refrigerators that are not broken down at lower atmospheric levels and rise to the upper levels, destroying ozone.

Clauser-ology: Cloudy with a chance of meatballs

Real Climate

Before we get into the details of what is going here, let’s look at some of the stranger claims about climate science he has made: The “IPCC and others” use a “cloud-free” Earth. Clauser however takes that number, removes 80 and 20 W/m 2 for atmospheric absorption by ozone (!!)

A NOAA-STAR dataset is born…

The weighting varies a little between land and ocean, and as a function of topography or surface type (some model-observation comparisons take this into account, but a global uniform weighting is often good enough). It’s not a democracy where the ‘right’ answer is decided by majority vote! But why should this be so?

Summer Air Pollution Trends: Factors Affecting Air Quality

Breezometer

We explore the causes for worsening wildfire events around the globe in more detail here. Levels of Ground-level Ozone Pollution Can Increase in Summer. As ground-level ozone requires the presence of sunlight to form, high heat and sunny weather can function to increase concentrations of this particular pollutant.
