Sentences with phrase «gas age»
The long lag of CO2 is probably not the result of timing errors between ice age and gas age in the ice core, as methane more closely follows the temperature record (for the timing, see also the discussion at UKweatherworld).

We calculate the WD gas age - ice age difference (Delta age) using a combination of firn densification modeling, ice - flow modeling, and a data set of d15N - N2, a proxy for past firn column thickness.
If you back - calculate the emissions vs. the increase in the atmosphere over the past 100 + years, the zero emission level is around 300 ppmv, not that far of what can be found in ice cores of 100 year old gas age.
Despite multiple careful studies, uncertainties in the ice — gas age differences for the Vostok ice core remain of the order of 1 kyr.
The WAIS Divide deep ice core WD2014 chronology — Part 1: Methane synchronization (68 - 31 ka BP) and the gas age — ice age difference Climate of the Past, 11, 153 - 173

There's plenty of additional discussion of «the gas age» on Dot Earth.
Nothing I, or anyone else writes, will change the reality that the gas age is here for many years to come.
Bring more oversight to the gas age.
Between the clean gas and the shale options, though, is it fair to say this is «The Gas Age»?
And if you've been reading here for awhile, you're aware of the reality, for better and worse, of «oil's long goodbye» and «the gas age.»
New constraints on the gas age - ice age difference along the EPICA ice cores, 0 — 50 kyr.
The lag is a different (and mostly unresolved) problem: while the lag during warming periods is explainable as the about 800 year turnover time for deep ocean down / upwelling flows, the much longer delay of CO2 during periods of cooling towards a new ice age is difficult to explain, the more that methane does follow temperature far more closely, thus errors in ice age — gas age difference are not at the base of the lag...
Figure 1: Antarctic (Vostok) ice core records of temperature, CO2 (upper) and CH4 (lower) including time - scale adjustment to account for ice - gas age difference associated with the time for air bubbles to be sealed (Petit et al. 1999) and corrected for variations of climate in the water vapor source regions (Vimeux et al. 2002) as described in Supporting Text of Hansen and Sato (2004).
