We find (i) measurements at all scales show that official inventories consistently underestimate actual CH4 [methane] emissions, with the natural gas and oil sectors as important contributors; (ii) many independent experiments suggest that a small number of «super-emitters» could be responsible for a large fraction of leakage; (iii) recent regional atmospheric studies with very high emissions rates are unlikely to be representative of typical natural gas system leakage rates; and (iv) assessments using 100 - year impact indicators show system - wide leakage is unlikely to be large enough to negate climate benefits of coal - to - natural gas substitution.

A scientist at the Natural Resources Defense Council warns that the study could underestimate the number of chemicals in women's bodies, which is surely true given that as more testing is done, with ever higher levels of sensitivity, more of the chemicals out in the world are, unsurprisingly, found in our bodies.

Anyway, the point I was making is that older solar variation estimates are over used (by both camps, er tribes) and that natural variation could quite possibly be underestimated.

Additionally, a recent comprehensive study of measured natural gas emission rates versus «official» inventory estimates found that the inventories consistently underestimated measured emissions and hypothesized that one explanation for this discrepancy could be a small number of high - emitting wells or components (33).

Conversely, if «climate sensitivity» for a doubling of CO2 is based on recent measurements and CO rates, and past natural variability is underestimated — as you've shown here — then this implies our estimates of sensitivity per CO2 doubling is too high, not too low.

If, for example, scientists had somehow underestimated the climate change between Medieval times and the Little Ice Age, or other natural climate changes, without corresponding errors in the estimated size of the causes of the changes, that would suggest stronger amplifying feedbacks and larger future warming from rising greenhouse gases than originally estimated.
