Michael, Nope, never gonna happen I loves my dead cow grilled over charcoal - yummy!
As to water vapor, read my essay - I personally do not consider water vapor as a greenhouse gas - It is a MULTIPLIER of the effects caused by the 4 classic gasses. Further more the amount of water vapor is determined by temperature in an ever increasing spiral.
Nitrous oxide (better known as laughing gas) emissions are produced by both natural and human sources. Natural sources include soils under natural vegetation and the oceans. Natural sources create 62% of total emissions. Human sources come from agriculture, fossil fuel combustion and industrial processes. Human-related sources are responsible for 38% of total emissions.
Though only 38% of the total, these human activities have added large quantities of reactive nitrogen compounds to the environment and have virtually doubled the mainly natural inputs existing at the beginning of the industrial age. This has increased nitrous oxide emissions by about 40-50% over pre-industrial levels.
Before the Industrial Revolution, the atmospheric concentration of nitrous oxide was maintained in a safe range of levels by natural sinks. But for a long time now human activities have been creating emissions much more rapidly than the Earth can remove them. Nitrous oxide levels are now higher today than at any other time during the last 800,000 years
So while these human sources of nitrous oxide are smaller than natural emissions, they upset the balance in the nitrogen cycle that existed before the Industrial Revolution. Before the influence of humans, nitrous oxide levels were quite steady because of this natural balance.
Soils under natural vegetation create 7.3 million tons of nitrous oxide each year.
Ocean microbes acting on sinking pellets produce 4.2 million tons of nitrous oxide annually.
Chemical reactions in the atmosphere, i.e., the oxidization of ammonia from natural sources creates 660,000 tons of nitrous oxide annually.
Now add the 7.7 million tons from human activity and – Problem!
OK, back to methane, as you posted there natural sources of methane emissions. The main natural sources include wetlands, termites and the oceans. Natural sources create 36% of methane emissions. Whereas human sources such as landfills, livestock farming, as well as the production, transportation and use of fossil fuels create the majority of methane emissions, accounting for 64% of the total. So as with nitrous oxide, the atmospheric concentration of methane was maintained in a fairly constant range by natural sinks.
Once the Industrial Revolution began we have seen methane levels more than double over the last 150 years. Human activities have been creating methane emissions much more rapidly than the Earth can remove them, increasing global methane levels. During the last 800,000 years, methane concentrations naturally varied between 350-800 ppb but since the Industrial Revolution, methane levels have become much higher and are now 2.5 times larger.
The Cooling Earth – as you posted, there are indeed some scientists, that have been arguing that the world is indeed headed for a cooling phase based on solar cycles. Scientists from Germany to India have argued that weakening solar activity could bring about another "Little Ice Age."
There has been decreasing solar activity since 1998. From 1900 to 1998, solar radiation increased by 1.3 W / m², but since 1998 it has diminished, and could reach values similar to those of the early 20th century. Based on the number of sunspots which vary in a cyclic pattern not since cycle 14 peaked in February 1906 has there been a solar cycle with fewer sunspots. We are currently more than six years into Solar Cycle 24 and the current nearly blank sun may signal the end of the solar maximum phase. Historically, going back to 1755, there have been only a few solar cycles in the previous 23 that have had a lower number of sunspots during its maximum phase.
So Michael, what I see is not a global conspiracy but, as with all human activity, those who jump on the bandwagon and beat the drum for their own gain.

The Glass is Half Empty People and The Glass is Half Full People. I am one of the latter. I generally appreciate the world and the universe I find myself in. There's little to nothing I would change about any of it. It's not FAIR. It's CRUEL. It's ARBITRARY. It's ABSOLUTE. ... And I have FAITH in the whole lot of it.
