Sentences with phrase «since atmospheric aerosols»

The relative importance of the various aerosol components is critical for the aerosol climatic effect, since atmospheric aerosols behave differently when their chemical composition changes.

Not exact matches

These components — specifically aerosols (particulates in the air — dust, soot, sulphates, nitrates, pollen etc.) and atmospheric chemistry (ozone, methane)-- are both affected by climate and affect climate, since aerosols and ozone can interact, absorb, reflect or scatter solar and thermal radiation.

But this is silly, since the atmospheric lifetime of aerosols is just a matter of days, so once we stop burning coal, as we eventually must, the aerosols disappear quickly, unmasking the pent - up warming due to all the extra CO2 we emitted by not switching from coal to natural gas.

Climate simulations including atmospheric aerosols with chemical transport have greatly improved since the TAR.

Since the inception of the program (1960s) our understanding of the behavior of atmospheric aerosols has improved considerably.

This is as to be expected, since continued efforts to reduce atmospheric aerosols in the West have resulted in less dimming (more warming), while in the East increasing pollution has caused more dimming (less warming).

Perhaps, more relevant: an astronomer noted that during the period since 1995 when the brightness of the Full Moon is measured (he claims a good indicator of atmospheric volcanic aerosols) it has been at the highest levels since the 60s.

The 2007 Fourth Assessment Report compiled by the IPCC (AR4) noted that «changes in atmospheric concentrations of greenhouse gases and aerosols, land cover and solar radiation alter the energy balance of the climate system», and concluded that «increases in anthropogenic greenhouse gas concentrations is very likely to have caused most of the increases in global average temperatures since the mid-20th century».
