What the Global Warming Thought Police and Al Gore-style morons fail to appreciate is that greenhouse gasses have resuscitated a totally frozen Snowball Earth on more than one occasion in the history of our planet.

Long odds that Earth could support life. All delicately arranged, seemingly.
What the Global Warming Thought Police and Al Gore-style morons fail to appreciate is that greenhouse gasses have resuscitated a totally frozen Snowball Earth on more than one occasion in the history of our planet.
From what I recall of the climate data from the mars rovers it seems that the warmest day they've seen was a steamy -25 degree summer day.
Granted it's further away but it's a good example of what getting rid of the CO2 can do for us.
Interesting photo, but it leaves lots of unanswered questions (IANAPG - I am not a paleogeologist). Assuming that the banded iron deposits are evidenced by the horizontal striations, what would be the cause of the lighter, angled coloration extending through those layers? It would not seem to be an indication of some other type of sediment. Perhaps it represents the effects of geologic forces acting on the sedimentary layers, indicative of twisting or upward thrusting forces? Or something else?
The Martian atmosphere is almost all CO2 and the warmest recorded temperature ever on Mars is about 40 degrees F. Not warm but not bad, it is a rare event tho
bump for later, thanks!
Guess I was thinking the CO2 was mostly locked up in the poles.
The Martian atmosphere is also only about 10 millibars of pressure (1% Earth). Not much CO2 or anything else there.
It also lacks the main greenhouse gas in the atmosphere. H2O
Oh man, I'm so glad I saw this story! I was just asking myself the other day, "How did the young earth avoid becoming a giant snowball?" I mean, it bugged me for the whole day -- I kept asking everyone at my office, calling my friends, but no one knew!
Wow, what a relief -- to finally find out the answer to that pressing question. Now, if someone could just tell me how teenage earth avoided becoming a massive fireball, my life will be complete!
A bane? Don't you mean a blessing?
No carbon dioxide = no plants.
No plants = no animals.
No plants + no animals = NO LIFE.
"If it gets cold, ice caps form, chemical weathering decreases, carbon dioxide accumulates in the atmosphere, which increases the greenhouse effect and surface temperatures. If it gets hot, the rate of chemical weathering increases, the rate of burial of sedimentary carbonates increases, the amount of carbon dioxide in the atmosphere and surface temperatures decrease," Dauphas said."
Does this or does this not sound like the C02 cycle acts as a natural thermostat on the atmosphere. During "cold" spells (ice ages) C02 accumulates in the atmosphere, which eventually produces a greenhouse affect, which produces a warm spell ("global warming"), which causes faster rate of the carbon sink affect, which decreases atmpospheric CO2 and temperature over time, leading to another "cold spell" which leads to another "warm spell", etc., etc., etc.
What then, if anything, can be the net "human affect" on this? It can only be the shortening of the time between the peaks and valleys of the cycle, and possibly addding the attainment of smaller peaks and valleys during those shorter cycles.
Which could mean, possibly, that any "warming" will end sooner than currently predicted, which will be followed by a cooling, which will only end in a shorter time if............we are still affecting the carbon release/carbon sink cycle.
If, instead, our activity increases the carbon sink during an upcoming warming (which reducing greenhouses gases will do), then the warming point in the cycle will last longer, and possibly reach higher temperatures before the atmospheric CO2 becomes high enough to trigger net additions to the carbon sink; that would bring in the cooling point in the cycle again.
Even if "human activity" is part of "global warming", the "global warming" political agenda could be the opposite of what we need to do; because of how C02 works as a natural thermostat. The warm cycles produce the C02 conditions leading to the next cool cycle and the cool cycles produce a C02 condition leading to the next warm cycle. The source (medium of exchange) is not important. Each cycle, cooling or warming, produces the C02 conditions for its reversal, based on the C02 balance, not how slowly or quickly it is obtained.
"..when astrophysicists believe the sun was 25 percent fainter than today."
There's my highlight of the article!
I'm surprised they don't mention it in this article, but I believe some of the oldest fossils (bacteria) can be found in some of the Canadian shield precambrian rock and date to almost 3.5 billion years ago.
