Stonepark Posted December 14, 2015 Report Share Posted December 14, 2015 There is a time lag (although very short in geological terms) between the increase in atmospheric carbon and global temperature rises, so we have only just begun to see the difference in temperature show itself from the last 100 years. CO2 has been an indicator of temperature rises in the past and has followed those rises. In general CO2 levels are symptoms,not cause of temp rise. Solar cycles resulting in ocean cycles drive it all and that is where the focus should be. With the CO2 argument, 2 things need to be considered:- 1)By effect. 95% of greenhouse gas heat retention is caused by water vapour, CO2 is only responsible for 3.75% 2) if for sake of argument you liquify atmosphere and look at volumes (as all gases are liquids just not very dense - this would raise sea level by 38 feet) so called scientists are currentlty arguing that the equivilent of 2 inch of liquid co2 (0.04%), across the planet is more important than the sun output cycle, the atmospheric water vapour component or the 12100ft of average h20 ocean depth for heat retention and absorption.

As I've said before, this is an extremely complicated subject involving interactions between many, many different systems, the outcomes of most of which they can't fully predict, but to take your figures above is to ignore several major factors. For example, available water in the system is relatively constant - unlike CO2 which is increasing at exponentially (it's like having a full glass of beer, adding a splash of lemonade will not only ruin it but make it over flow), secondly, the 3.75% you quote is due to a minuscule 0.04% of the atmosphere that is CO2 so it has a massively larger effect than water vapour. Thirdly water vapour can condense which then increases the albedo - which lowers surface temperatures. There are many other interactions due to sea temp and the ability to dissolve CO2 and other related acidification issues (the depth at which carbon rich shells dissolve for example) to consider before simplistic arguments can be regarded. This is a really large and complex issue, of which the sun's output is only one factor, and I doubt anyone here is a climate scientist, so really any gut feeling or emotional response is pretty worthless and we really have to look to science for predictions and responses, as we do for many other areas of our lives.

BrowningB525 Posted December 14, 2015 Report Share Posted December 14, 2015 1) We are still rebounding from the Little Ice Age of the early 1800. 2) Ice core records show CO2 levels lagging temperature by ~ 800 years. We have nothing to worry about, in 50 years people will roll around laughing about the 'olden days' if you mention "carbon footprint". Or they'll remember the use of CFCs and the damage they did to the ozone layer. before being banned. Quote Link to comment Share on other sites More sharing options...
flynny Posted December 14, 2015 Report Share Posted December 14, 2015 (edited) And what caused the last ice age, dinosaurs passing wind? This planet's been getting on, with us and without us for a long, long time, and continues to do its own thing. Lol. A lot of truth is said in jest. Cattle farming is the biggest contributor So will cows farts be the end of us all lol Who cares I like meat mmmmmmmmmmmmm I also like shooting on farmland lol Atb Flynny Edited December 14, 2015 by flynny Quote Link to comment Share on other sites More sharing options...
