Sentences with phrase «cycle effects of greenhouse gases»

If it includes a requirement to consider the life - cycle effects of greenhouse gases associated with the coal to be extracted, it might tip the scales against the new mine.

Not exact matches

The second step involved calculating Earth's energy balance for this time period, using estimates of greenhouse gas concentrations extracted from air bubbles in ice cores, and incorporating astronomical factors, known as Milankovitch Cycles, that effect the planetary heat budget.

[Response: These feedbacks are indeed modelled because they depend not on the trace greenhouse gas amounts, but on the variation of seasonal incoming solar radiation and effects like snow cover, water vapour amounts, clouds and the diurnal cycle.

Put the Water Cycle back in and there is no Greenhouse Effect of «greenhouse gases heating the Earth 33 °C from -18 °C, because, and please listen carefully, water vapour the main greenhouse gas actually cools the atmosphereGreenhouse Effect of «greenhouse gases heating the Earth 33 °C from -18 °C, because, and please listen carefully, water vapour the main greenhouse gas actually cools the atmospheregreenhouse gases heating the Earth 33 °C from -18 °C, because, and please listen carefully, water vapour the main greenhouse gas actually cools the atmospheregreenhouse gas actually cools the atmosphere by 52 °C.

A self stabilising system which is as well capable of neutralising any ocean skin effect as it is capable of neutralising negative ocean cycles, positive ocean cycles and any warming of the air by any increase in greenhouse gases.

They concluded that with a bit of help from changes in solar output and natural climatic cycles such as the El Nino Southern Oscillation (ENSO), the growth in the volume of aerosols being pumped up power station chimneys was probably enough to block the warming effect of rising greenhouse gas emissions over the period 1998 - 2008.

Could an increase in greenhouse gases actually have a cooling effect over water by speeding up the rate of evaporation from the oceans thereby extracting energy faster from the oceans, speeding up the hydrological cycle and pushing energy faster to space?

Declining solar insolation as part of a normal eleven - year cycle, and a cyclical change from an El Nino to a La Nina dominate our measure of anthropogenic effects because rapid growth in short - lived sulfur emissions partially offsets rising greenhouse gas concentrations.

They did not, the Met Office now accepts, take sufficient account of «natural variability» — the effects of phenomena such as ocean temperature cycles — which at least for now are counteracting greenhouse gas warming.

If the Maunder and Dalton minima actually did affect the climate, then a new one might counteract the effects of the extra greenhouse gases people are now pumping into the atmosphere — at least, until the solar cycle returns.

Past interglacial warming were triggered by sharp spikes in solar irradiation associated with the Earth's position relative to the sun (Milankovic cycles), with consequent feedback release of greenhouse gas (CO2, CH4) from the oceans and the biosphere, resulting in atmospheric infrared radiation effects and in melting of ice sheets, which amplify global warming.
