I'm having trouble figuring out what you're arguing FOR
@RiverCard.
Conservation in human activities rather than sanctimonious contrived "environmentalism."
My best interpretation is that you see no difference between burning wood and burning fossil fuels - that they are equally to blame for the increase in carbon in the atmosphere and they are equal problems that need resolution. Is that it?
Yes, it was in response to "I agree about personal actions, having lived most of my life totally fossil fuel free, even to the point of cooking with firewood, on sailboats." Burning a processed "clean" fuel like propane or butane to cook in the open would be preferable since it not only is likely more efficient because of relative heat values but also nearly eliminates the discharge of soot/particulates.
As I said before, I agree with you that chemically CO2 is CO2 (modern or ancient). The problem isn't that CO2 is CO2, or that CO2 is bad. CO2 isn't bad, any more than H2O is bad. The problem is that the concentration of CO2 in the atmosphere is on the high side (measured against geologic history), and more importantly, the increase in the CO2 concentration has happened on a time scale measurable in human terms instead of geologic terms. And its still increasing. That increase is primarily coming from the mining of long buried hydrocarbons and burning them, rather than cutting down forests and burning those.
It's not helpful either that large swaths of rain and other forests have been increasing leveled since it curtails the forests' absorption of atmospheric CO2 and release of O2. The felled trees are no longer generally used as fuel (although many are just burned to dispose of them) but the land is cleared for pastures, raising crops, and human residential developments. Humans and the mammals they consume act in reverse of photosynthesis--consuming O2 while inhaling and exhaling breath with a 100x higher CO2 concentration than in the air breathed in. There are trade-offs in all human activities, and population growth is increasingly stressing Nature; nonetheless, prudent use of natural resources has progressively provided abundant efficient, inexpensive energy while improving the health and comfort of most in developed nations.
H2O at too high of a concentration is also bad for humans.
No argument. Water vapor is much more prevalent than CO2 in the atmosphere, is a stronger GHG, and a major influence on weather/climate.
Regarding soot / particulates, that too is an issue. But its a change of topic / change of argument relative to carbon emissions. I am in full agreement that the soot from burning stuff, whether wood / biomass, or fossil fuels, is also an issue. As best I can tell, and without this different topic getting too big, the details of those issues vary depending on what you're burning. Burning wood creates soot / particulate problems that are different from burning coal, that are different from burning natural gas, that are different from burning other various grades of crude oil. Is it the soot / particulates from burning stuff that is really what you're arguing about?
