Sentences with phrase «total effects of all greenhouse gases»

However, if one converts the total effects of all greenhouse gases, aerosols, etc. into an equivalent increase in CO2 concentration (by reference to their effective radiative forcing RF, that from a doubling of CO2 being F2xCO2), then what you suggest would be pretty much in line with the generic definition of TCR in Section 10.8.1 of AR5 WGI:

In addressing the question of the effects of greenhouse gases on Atlantic tropical storms, it might clarify (and even partially defuse) the controversy to lump internal variability together with other forced responses (particularly aerosols), rather than to focus on internal variability vs the total forced response.

You argue that this «slowdown» is evidence against the truth that an increased greenhouse gas effect slows down the rate of heat flowing out of the planetary system and thus increases the total heat in the system.

The contribution of greenhouse gases is greater than the observed warming, while the total anthropogenic contribution is thought to be around 0.7 °C because of the cooling effect of aerosols.

John Carter August 8, 2014 at 12:58 am chooses to state his position on the greenhouse effect in the following 134 word sentence: «But given the [1] basics of the greenhouse effect, the fact that with just a very small percentage of greenhouse gas molecules in the air this effect keeps the earth about 55 - 60 degrees warmer than it would otherwise be, and the fact that through easily recognizable if [2] inadvertent growing patterns we have at this point probably at least [3] doubled the total collective amount in heat absorption and re-radiation capacity of long lived atmospheric greenhouse gases (nearly doubling total that of the [4] leading one, carbon dioxide, in the modern era), to [5] levels not collectively seen on earth in several million years — levels that well predated the present ice age and extensive earth surface ice conditions — it goes [6] against basic physics and basic geologic science to not be «predisposed» to the idea that this would ultimately impact climate.»

While the greenhouse gas footprint of the production of other foods, compared to sources such as livestock, is highly dependent on a number of factors, production of livestock currently accounts for about 30 % of the U.S. total emissions of methane.316, 320,325,326 This amount of methane can be reduced somewhat by recovery methods such as the use of biogas digesters, but future changes in dietary practices, including those motivated by considerations other than climate change mitigation, could also have an effect on the amount of methane emitted to the atmosphere.327

Since 2004, researchers in NOAA's Global Monitoring Division have released the Annual Greenhouse Gas Index: a single value that compares the total warming effect of each year's concentrations of heat - trapping gases to 1990 levels.

● Saturation of CO2 greenhouse effect by water vapor that is actually the main greenhouse gas, responsible for 90 % of the total greenhouse effect.

Through the program the Secretary will make grants to public and private institutions of higher education to study the effects of consumer behavior on total energy use; potential energy savings from changes in consumption habits; the ability to reduce greenhouse gas emissions through changes in energy consumption habits; increase public awareness of Federal climate adaptation and mitigation programs; and the potential for alterations in consumer behavior to further American energy independence.

[«Noncondensing greenhouse gases, which account for 25 % of the total terrestrial greenhouse effect...»]

Non-condensing greenhouse gases, which account for 25 % of the total terrestrial greenhouse effect, thus serve to provide the stable temperature structure that sustains the current levels of atmospheric water vapor and clouds via feedback processes that account for the remaining 75 % of the greenhouse effect.

Noncondensing greenhouse gases, which account for 25 % of the total terrestrial greenhouse effect, thus serve to provide the stable temperaturestructure that sustains the current levels of atmospheric water vapor and clouds via feedback processes that account for the remaining 75 % of the greenhouse effect.

The resulting optical depth curve is a measure of the total greenhouse gases by effect over the last 61 years.

The total amount of greenhouse gases by effect (water vapour plus CO2) has hardly changed, so the warming was not caused by greenhouse gases.

Greenhouse gasses have a lesser effect, of which Co2 is a minor greenhouse gas, and man released Co2 is a portion of tGreenhouse gasses have a lesser effect, of which Co2 is a minor greenhouse gas, and man released Co2 is a portion of tgreenhouse gas, and man released Co2 is a portion of that total.

After all CO2 is itself only a tiny portion of total greenhouse gases so that it can not have any significant long term effect when the water vapour primarily affecting atmospheric heat retention is in turn itself but a tiny proportion of global heat retaining capacity when one adds in the vastly greater oceanic heat retaining effect.

Cities are responsible for about 75 percent of the world's total energy - related greenhouse gas emissions, while the vast majority of them are located on or near the coast, making cities especially vulnerable to the dangerous effects of climate change.

When more than one greenhouse gas simultaneously absorb in the infrared their total combined absorption effect is not the arithmetic sum of their individual absorption effects.

Given that > 93 % of warming is going into the oceans, ~ 2.3 % into the atmosphere, even a small rate change in ocean warming relative to the total greenhouse gas imbalance will have a huge effect on air temperatures.

Note that this is only part of the story since, as far as we are aware, no one has yet investigated a counterintuitive parallel effect — condensation and precipitation will likely reduce the total lower atmospheric concentration of that ubiquitous greenhouse gas, water vapor, so increasing clear sky radiative cooling.

This is because some of the gases absorb and emit radiation at the same frequencies as others, so that the total greenhouse effect is not simply the sum of the influence of each gas.

While methane and nitrous oxide make up much smaller portions of total greenhouse gas emissions, these gases are still important factors in the climate crisis, in part because they each have stronger global warming effects than carbon dioxide and also because they constitute an increasing portion of total emissions.

To calculate total warming and cooling potentials, the total effect of aerosols and greenhouse gases (GHG's) needs to be calculated.
