RE:RE:RE:CO2So you have some questions. I'll answer them.
- '1st the level of CO2 in the atmosphere is about 1/2, or less than it was a few million years ago. Why is it that human caused CO2 is just now supposedly the cause of the rising temperature?' : To study global warming evolution, CO2 levels is not enough, you must study sun activity too. There has been global cool down with very high CO2 levels but only when sun activity was much more lower. Since industrialization, sun activity is pretty equal, CO2 from oceans, volcanoes, soils, plants and animals is not raising, but obviously CO2 produced by humans activities is. Sun activity is studied from carbon14...
- 'How did it become warm enough 140,000,000 years ago for cyprus trees to grow - and indeed - dinosaurs to roam the area around Fort McMurray when humans had not began to evolve.' : Like I said, CO2 is produced 'naturally' too. It has not always been equal. An sorry to repeat mysel again, but the sun activity has to be understood.
- 'The warming had ceased for the last 18 or so years' : What??? What is your source? This is absolutely false. Do you believe in any official data source? Just google 'NASA global warming chart'. Maybe I have to specify that this is about global warming not local.
- Since you introduced the El Nino effect, just know that this effect is just becoming stronger with the global warming.
Do you believe in science (math, chemistry, geology)? I do. Believing in it might even be an opinion for the fools. But if you believe in it, global warming caused by industrialization is just a fact.
The problem is not the global warming in itself, but the fact that it is going much more faster then humans can adopt to it without too much pain and loss : move cities, adapt new ways of travelling, change daily habits (food choices), welcome strangers, etc. As a group or specy, we do not evoluate very fast in these. I think that your post, Darrow100, is a proof of that. Just like a reply from Calgary_AB on the same subject.
Everyone is involved in this. I think that going from fossils fuels energy to green ones must compensante everyone. For example, I think that coal workers who loose their job must be compensate but certainly not by reopening their mines. Big solutions and investments must be made to help everyone since it is a global problem. We are in a period of confusion and evolution. But futures generations will probably not have any kind of right to deny global warming effects...
