It makes sense, then, that high - vitamin cod liver oil should serve as a safe standalone supply of vitamin A even during the winter, while liver from land animals should either be used during seasons where the supply of UV - B rays from the sun is rich enough to guarantee adequate vitamin D, or in conjunction with vitamin D - rich foods such as lard from pastured pigs, oily fish, shellfish, and egg yolks from pastured chickens, all of which supply smaller but substantial amounts of vitamin D. (For a list of these and other food sources of vitamin D with specific concentrations listed, see Appendix 3.

Northern hemisphere concentrations are a bit higher than they are in the Southern hemisphere (here), but the magnitude of the difference is small enough to support the conclusion from the methane budget that tropical wetlands, which don't generate much interhemispheric gradient, are a dominant natural source (Kirschke et al 2013).

Carbon dioxide removal addresses the root cause of climate change — high concentrations of the greenhouse gas in the atmosphere — and generally have well - understood benefits and risks, but current technologies would take decades to achieve moderate results and be cost - prohibitive at scales large enough to have a sizeable impact.

What I think you mean is that if we get CO2 levels high enough to cause a serious problem, we can't just stop emitting and hope the concentration will drop in time to make a difference, whereas with methane, it decays fast enough that we need to worry more about the decay products than about methane itself.

Methane that escapes the sea is generally a small fraction of methane that is released from clathrates at the sea floor, though if the concentration rose high enough so much could make it to the atmosphere that the impact of methane as a GHG in air (before it devolves to CO2 in air) overwhelmed the negative effects of methane decomposing to CO2 in the oceans..

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
