showing that abrupt climate change is a matter of serious concern

Anyone who wants to experience abrupt climate change only needs to move to Ohio. This past year we had a period where the temperature dropped 42 degrees (F) in just under 24 hours. Whoa boy.

The goal to reduce carbon emissions is obvious, and this sounds like a good start (especially as one commenter noted -- on small scales to start, residential sidewalks, etc) but has anyone thought about the potential for impact of removing such a large portion of C02 from the environment on our fauna that requires CO2 for survival? I know we're putting off more than nature would due to processes like the creation of concrete, but could that mean that the plants of today are now depending on it? One argument could be that the amount of fauna in the world has decreased over the last 50-100 years (which is probably true), but could taking away all this extra "food" for the plants in a relatively short time span (5 years, 10 years, etc) have a serious negative impact on the greener places in the world?

I'm all for green, but we need to make sure we look at it from all sides, not just the obvious one.

I don't know who you are. I don't know what you want. If you are looking for ransom, I can tell you I don't have money. But what I do have are a very particular set of skills; skills I have acquired over a very long career. Skills that make me a nightmare for people like you. If you let my laptop go now, that'll be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I will upgrade your Windows XP to the original version of Vista that is completely unpatched and very vulnerable.

They mostly come out at night.... mostly.
