*Atmospherics plays the biggest part, in all of that. I don't think anyone of sound logic can deny their is general warming for Earth. My only sticking point, as it is for thousands in the scientific community, is people running around blaming engines or this or that. Man can be very egocentric in wanting to always take the blame or credit for everything....that is pretty simplistic. --<font color="#1E90FF" face="Comic Sans MS">[[User:TK|şŷŝôρ-₮K]]</font><sup><font color="DC143C">[[User_Talk:TK|/Ṣρёаќǃ]]</font></sup> 14:29, 14 October 2007 (EDT)

:On the other hand, there are very few other things which we ''can'' blame for the warming. Solar activity, on average, has gone down in the past 30 or so years which, even accounting for time lag, should result in decreasing temperatures, something which hasn't been seen. Cosmic rays similarly have been on the decrease, and the hypothesis had some major flaws in the first place.
:Coupled with these two things, we are somewhere in the middle of the current climate cycle, and shouldn't be able to discern any significant trend in global temperatures. We are able to, however, and we can also see (by comparing instrumental records with historical proxy data) that the current rate of change of temperature is unprecedented.
:The warming was not produced by humanity alone; solar activity probably contributed up to 0.18-0.2 degrees C warming prior to 1940. However, since then, it is extremely unlikely that natural forcings have had any significant warming effect (indeed, most research I've seen suggests a net cooling from natural forcings over the twentieth century).
:I'm of the opinion that nuclear power in combination with renewables and feasible substitutes for the products of crude oil should be able to see us through with little, if any, effect on our quality of life, not to mention also remove our current dependence on oil (which is primarily found in the politically unstable Middle-East, with smaller amounts also in Russia and even less in the USA) which will not, after all, last forever. --[[User:Scientist|Scientist]] 14:42, 14 October 2007 (EDT)
