More moderate than the worst case predictions, not the ones with the highest confidence. The paper also is self-published and not picked up by a major journal, which usually says there's problems with it.Duke University just published a study that states Global Warming is more moderate than the IPCC scenarios.
Duh, the media loves to sensationalize everything. Why focus on the high probability scenarios when you can scare the crap out of everyone with the unlikely, extreme scenarios. You get more money from both the supporters and deniers if you do that.Most of the IPCC Scenarios that we hear about in the media are "worst case" scenarios.
Thankfully, you're not a climate scientists, so your beliefs (like mine) don't matter a darned bit. Among scientists qualified to hold an opinion, anthropogenic climate change is not in doubt. As you noticed, the magnitude of warming is still uncertain.I do not believe in the "worst case" scenarios of global warming or that man is the primary cause.
Depends on how you define pollutant. If pollution means byproducts of doing things that we need to do which have negative consequences for the environment and us, then the amount of CO2 we're talking about absolutely is a pollutant.CO2 is not a pollutant.
While I agree with you that a whole-system view is more useful than focusing on one specific symptom, CO2's role in climate change is a bigger danger to us and our children than anything you listed.If we put 1/2 the money spent on CO2 reduction into reducing real pollution (NOx, SOx, Lead, Mercury, etc) we would be much better off. An also probably reduce CO2 as a side benefit.
If our emissions, no matter their size, are measurably stepping on the gas pedal of climate change, they're a problem. And they are.Our contribution to CO2 in the atmosphere is minimal. About 4% per year.
First, your 1:1.5 ratio is off. Someone is doing chemistry wrong. If you do the reaction correctly, 1 gallon of diesel reacts with oxygen to form .99 gallons of water plus a bunch of CO2. While this doesn't really matter due to my next point, it's still worth being correct when possible.We are worried about running out of water. Did you know that burning 1 gallon of diesel fuel creates 1.5 gallons of water? All the fuel we are burning is actually adding water to the atmosphere. Isn't that a good thing?
It's still not a good thing. We're running out of potable water in places we need it. The water isn't disappearing, it's just moving to places we can't use it and becoming contaminated with things that prevent us from taking advantage of it. The water produced by oxidizing diesel only helps us if it comes back to the ground as rain or snow in a time and place we need it. If it falls somewhere we already have to much of it (flooding) or if it falls in the ocean, it doesn't help us at all. In fact, the contributions of that water vapor and the accompanying CO2 will just further accelerate climate change making things worse overall.
