People should be celebrating, not demonizing, modern increases in atmospheric carbon dioxide (CO2). In other words, the Earth came within 30 ppm in CO2’s atmospheric concentration of witnessing the extinction of most land-based plants and all higher terrestrial life-forms – nearly a true climate apocalypse.

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.

Planets orbiting the Sun-like stars of Alpha Centauri could be carbon-rich worlds with diamonds and graphite littered across their surfaces, say astronomers. Carbon world. Within our Solar System, for example, the carbon-to-oxygen (C/O) ratio is 0.5, meaning that there are twice as many oxygen atoms for every atom of carbon.

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.,

Outside of bird protection acts of the early 20 th century, protections for water, air and the atmosphere are a late 20 th -century development, created in the wake of Rachel Carson’s 1962 treatise on pesticides, Silent Spring. Carbon dioxide is not a pollutant. All of us are exhaling carbon dioxide right now.

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).
