As summarized by geoscientist James Kasting in his 2010 book «How to Find a Habitable Planet»,» [h] abitable zones around Sun - like (F, G, and Early K) stars should be relatively wide because of the natural feedback between atmospheric CO2 [carbon dioxide] levels and climate — the same feedback loop that kept the Earth habitable early its history.

When we talk about climate change, we're talking about the scientifically observable — and increasingly severe — changes in global climate patterns that became apparent in the mid-to-late twentieth century and can be attributed to the rising levels of atmospheric greenhouse gases (carbon dioxide, in particular) produced by human activities like burning fossil fuels.

This video provides a sense of scale for atmospheric pollution — both in total emissions and the rate of emission — by showing what the 54 million metric tons of carbon dioxide that New York City added to the atmosphere in 2010 would look like.

Like other tiny atmospheric particles called aerosols, black carbon (BC) has a short lifetime in the atmosphere of about a week because it is removed by rain or snow.

Like carbon dioxide, many non-CO2 atmospheric gases absorb in the infrared and contribute to climate forcing.

Only way plants could increase atmospheric CO2 is if carbon sinks like forests, the seabed are being destroyed.

To understand the policy implications of a carbon budget it is helpful to see the atmosphere as like a bathtub to the extent that it has limited volume and has been filling up with ghg so that atmospheric concentrations of CO2 have been rising in proportion to human activities which release ghgs.

«On the global scale, greenhouse gases like carbon dioxide cause the most concern related to climate change,» said Yun Qian, the paper's lead author and an atmospheric scientist at PNNL.

When atmospheric carbon dioxide is absorbed into the ocean, it reacts to produce carbonic acid, increasing the acidity of seawater and diminishing the amount of a key building block (carbonate) used by marine species like shellfish and corals to make their shells and skeletons.

«On the global scale, greenhouse gases like carbon dioxide cause the most concern related to climate change,» said Yun Qian, study co-author and atmospheric scientist at Pacific Northwest National Lab in the US.

By characterizing atmospheric gas mixing ratios (volume of gas per volume of air) across the North Slope, scientists hope to improve the estimates of the volume of gases like carbon dioxide and methane being emitted from biological sources such as Alaska's permafrost layer which stores large amounts of carbon.

These tests address questions like, what would happen to the Earth's temperature if atmospheric carbon dioxide suddenly quadrupled?

Notwithstanding the rest of the AGW science and what effect the carbon has, even a sceptic like me would like to see an abatement in the growth of atmospheric carbon.

Other effects like temperature - dependent CO2 solubility in ocean water, carbon stored in the land biosphere, weathering rates, and ocean nutrient inventories may help explain the rest of glacial − interglacial changes in atmospheric pCO2 (26, 27).

... A particular concern is that atmospheric levels of carbon dioxide may be rising faster than at any time in Earth's history, except possibly following rare events like impacts from large extraterrestrial objects.
