Hi.

I am trying to make sense of the global warming "it is / it isn't" mess
(which seems very culturally driven) as do-it-yourself seems the only
way to cut through the chattering voices. My final intent is to place
an analysis on the web.

Right now I'm needing data to build an analysis about. Carbon, CO2 in
the atmosphere and world temperatures together seem to be the basis of
the issue. What else should I throw in? Solar radiation??

Anyhow, here is my bucket of Q's for the moment... please, if you can
answer with a link or reference to where the data comes from I would be
very glad.


1.On early Earth, before plant life oxygenated the atmosphere, what
was:
1.1 typical temp ranges,
1.2 % carbon-dioxide in atmosphere
1.3 total tonnage of carbon in atmosphere
1.4 what colour was the sky (my guess is grey + orange tint ??)

2.On Earth before Industrial revolution, what was:
2.1 typical temp ranges
2.2 % carbon-dioxide in atmosphere
2.3 total tonnage of carbon held in:
2.3.1 atmosphere
2.3.2 living things - on land (if possible split plant life, animal
life)
2.3.3 living things - in sea (if possible split plant life, animal
life)
2.3.4 sequestered as subterranean deposits e.g. oil, coal
2.3.5 sequestered as sea floor deposits e.g. methyl hydrates
2.3.6 any others (??)

3.On Earth present-day (last 50 years), what has been :
3.1 typical temp ranges
3.2 % carbon-dioxide in atmosphere
3.3 total tonnage of carbon held in:
3.3.1 atmosphere
3.3.2 living things - on land (if possible split plant life, animal
life)
3.3.3 living things - in sea (if possible split plant life, animal
life)
3.3.4 sequestered as subterranean deposits e.g. oil, coal
3.3.5 sequestered as sea floor deposits e.g. methyl hydrates
3.3.6 any others (??)


Your answers appreciated - esp. with provenance i.e. traceability to
recent study or accepted works.

Also, what was the coldest it has ever been - ever? And hottest ever?

Is there a history of world temperature (a full timeline) on the web
please?

Thank you one and all!
