carbon

Carbon is neither created nor destroyed on planet earth. It exists in various states and storage places (i.e., reservoirs). That much is not disputed. But, some bolides contain carbon. Do any of you astronomy-types know (even an estimate) about how much new carbon enters our atmosphere on a...

I am starting this thread separate from the global warming thread because carbon sequestration and land use has its own merits only marginally related to the question of global warming. Please respect the topic so this thread doesn't get merged and we can discuss the emerging science without...

How do CO2 emissions correlate with happiness, both at a personal and national level? If substantial limits are placed on CO2 emissions, do you think will it have a net positive or negative impact on your lifestyle? In the long run, which populations will suffer and which will gain?

:eek: Researchers warn of nitrogen hazard to environment (AP) Next up: Nitrogen offsets for farmers who insist on destroying the planet by fertilizing their fields. They must pay.

A Hollywood environment war is being fought. The combatants are perennial "enviro-kook" Ed Begley Jr and nerd hero Bill Nye http://abcnews.go.com/Nightline/story?id=3413135&page=1

Is the fundamental premise of "organic food" - ie that it should be free from pesticides and any intensive agricultural practise itself bad for the environment? Insofar as it results in lower crop/meat yields per given area and thus necessitates greater agricultural land use..... Thus [for a...

This seems about right. Markets do follow leads. Somehow, however, I think this is as dead a lead as one can have. Still, it costs little for speculators to follow it so...why not!? linky It's good to be the king, but better to be his middle man.

Although left-leaning, if Salon keeps up at this pace with great articles like this, I'm going to have to get a subscription.

I'm not an ecologist, so tell me what's wrong with this, please. Carbon dioxide levels increasing through the burning of fossil fuels. Plants utilise carbon dioxide for photosynthesis. Trees lock up carbon in wood. Plant millions of trees and lower carbon dioxide levels. Would it take too...

This was the title of an article in Chemical and Engineering News, December 20th, 2004, page 36. The opening paragraph: As a PhD Inorganic chemist, my official position on this is: BWAAAHAHAHAHAHAHAHAH!!!!!!!! :roll: :roll:

I was looking for some info on the process. Any help would be appreciated. Thanks

Years ago I attended a panel at a scifi/fantasy convention: a panel on 'darwin was wrong' if you can believe that. Anyways, one of the panel members posited this, in regards to carbon dating procedures: 1. The archeologist goes to the carbon dater with the fossil. 2. The dater runs the test...

From my understanding, science uses ratios of Carbon-14 or Uranium-238, etc., to date older materials like fossils. Since scientists obviously cant observe the half-life for millions or billions of years, are there any tests to prove that the half lifes remain constant? Would there be any...
