What they showed are the distinct fingerprints of two kinds of forcing; increasing solar activity which warms all parts of the atmosphere, and carbon dioxide increases which warm the surface and troposphere, but cool the stratosphere and above. As you will recall, Hansen had declared in 1988 that “the greenhouse effect is here!”,

Extreme heat is not just an abstract notion: if we can’t cool our bodies enough, we’re in danger of neurological failure, organ failure and even death, with the risks highest for children and the elderly. On balance, clouds nearer the stratosphere warm us, whereas low-lying clouds tend to cool us because their greenhouse effect is smaller.

Also missing is any realization that clouds also contribute to the greenhouse effect (roughly 25% of the total) and so whether cloud changes warm or cool depends very much on where the clouds are (high clouds have a very different effect than low clouds for instance).

In the process, it consumes huge quantities of water, generates millions of tonnes of waste and accounts for 5–10% of global greenhouse gas emissions, making it one of the world’s most polluting industries. Synthesizing PE from raw materials also releases less greenhouse gases and waste heat than producing polyester or cultivating cotton.

The radiative forcing bar chart has gone full circle: Almost every IPCC report has a version of the radiative bar chart showing the contributions over the historical period of all the different forcings (greenhouse gases, aerosols, solar, etc.). Oddly enough this is most reminiscent of the very first bar chart that appeared in Hansen et al.

The Regulation’s proposed criteria for gaseous fossil fuels (which includes both conventional natural gas, and synthetic gas derived from coal gasification) allow investment in their consumption without restriction in function, scale, or time period, as long as greenhouse gas emissions are no higher than 100 gCO2eq/kWh (see §4.29-31

Methane is essential to control, since stabilizing climate requires reducing all anthropogenic greenhouse-gas emissions to net-zero. The issue is that total human radiative forcing includes several parts that heat and some that cool, so counting separate heating contributions like this leaving out the cooling parts gives too much heating.).

Much of the discussion of climatology in public discourse concerns anthropogenic climate change - the contribution of human activity to such events as carbon particles, greenhouse gases, and their effects such as the Greenhouse Effect and coral bleaching. This leads to the greenhouse effect. Greenhouse Gases.

There may also be an extreme variation between warm and cool seasons, including extreme winds and storms due to the mixing of cold and warm air. Surface albedo is high - heat acquired during the day is radiated at night. Many are not aware that deserts are a net carbon sink, providing some relief from the increase in greenhouse gases.
