The universe's age can be gleaned from the sizes of temperature ripples in the cosmic microwave background, such as these from the DASI telescope.

Working with a tough mentor named Yakov Zel «dovich, Sunyaev showed that the tiny acoustic vibrations in the universe moments after the Big Bang could be observed as temperature and density variations in the cosmic microwave background (CMB) radiation, the faint afterglow of the Big Bang that suffuses the universe.

In addition to measuring the temperature of the cosmic microwave background, Planck can determine its polarization, the direction in which the waves of light vibrate as they move through space.

The point at which a trend becomes clear within the average temperature data for a given region — known as the «time of emergence» — depends on when the source of the warming begins, how fast it happens and the amount of background «noise» obscuring the signal.

After scientists have done the hard work of working out these relations, it is possible to use one ice - core record to represent broader regions IF you restrict consideration to the parts that are widely coherent, so it is O.K. to plot a smoothed version of an Antarctic temperature record against CO2 over long times and discuss the relation as if it is global, but a lot of background is required.

Elsewhere, the background forecast model plays a stronger role, helping values of surface air temperature to be derived from other types of observation, such as sea - surface temperatures and winds.

The atmospheric Greenhouse Effect merely sets a theoretical background atmospheric temperature level that is continually overridden as a result of the size of the constant interlinked changes in both the solar and oceanic heat inputs.

Furthermore natural global temperature swings alter the natural background greenhouse effect constantly as water vapour held in the atmosphere increases and decreases naturally with changing global temperatures.

Hansen» rationalization of why, (as he states) «the five - year mean global temperature has been flat for the last decade», is interesting background information, but, of course, does not change the observed fact that there is this standstill, which he acknowledges.

lolwot — people with an agricultural background point out that northern latitude areas that can not grow certain temperature sensitive crops today, whereas in past years, such as the MWP, the same crops could be grown in those areas disprove Mann's hockey stick temperature reconstruction.

I would probably generally state it as «human CO2 activity has a measurable warming impact on global average temperature that can be readily discerned from the background of natural climate change and other human effects that may cause cooling, and this warming impact will be, in general, neutral in impact for humanity and the biosphere».
