Is Earth near its 'tipping points' from global warming?

It is true. Earth is at a tipping point. We have nothing to do with it though. The Earth is very near the end of one Galactic Day. At the end of one "wobble",and the start of a new one. One GD is 25,625 years. It happens on dec12,2012. Earth is less than six years from this event. The countdown clock is at 2079 days,12H,36M 22S

dec21,2012 Winter Solstice not dec12. Sorry bout that

Gerry,
solar output is in a minima on the 11 year cycle, but not the long term one.

Perhaps, but the Martian atmosphere would react very, very quickly to radiative forcing because of its thin atmosphere and lack of water vapor. Using the "Martian" warming as some signal that CO2 can't be the major current forcing factor here on earth just doesn't work.

Gerry, would you like to read my article which explains why CO2 is not the major forcing factor on our climate?

Edward, I would like to read your article which explains why C02 is nnot a major forcing factor.

You mean not the major forcing factor today? Sure Edward, if it's "science". By science I mean that your post doctoral research has been peer reviewed and subsequently published. But if not, I'd rather not hear the same "talking points" over and over again such as creationists do to "disprove" evolution.

from what sources do you get your information and what effect is this going to have on the life on this planet?

he apears to be referring to the aztec calender, which ends on dec 22 2012 when the earth is lined up with the center of the milky way, the cycle either starts over or the end happens. the spanish, in their wisdom destroyed too many of the aztec's written records for anyone to know for sure.

My article is here;

it is definitely science, but it is not peer reviewed. I wrote it for my university newspaper.

But there are many cycles within cycles
1/ the spin of the universe round it's centre
2/ the spin of galaxies
3/ the spin of our own "solar system"
4/ the spin of the earth
to list just the most obvious
then of course the belief that the Universe is currently an "expanding unit" whilst it spins.

I think global warming is great, gone with the cold! ;-)

Edward,
Thanks for sharing your article.

Thanks John, as you can see, I feel quite strongly about the subject lol :)

I don't think the Earth is near the tipping point, but Al Gore is. His head gets bigger every day. He's gonna be like the friggin elephant man soon. Send him a check though, I'm sure he's an honest man with no hidden agenda.

Rainbowkat- WIki "Milankovitch Cycles". As far as the effect on "life" I care not. A cycle is coming round full circle, nothing more or less. Cycles represent "change", good or bad. Change will happen and mankind is not big nuff ta stop it. Nor make it happen. The closest mankind has came ta making anything happen to the Earth took place on July 9, 1962. The GVT. of the USA did succeed in temporarily warping the Van Allen Belt during a high-altitude nuclear test. Mankind is still here.

Good reading Edward. Not being "peer reviewed and published" does not make you a dummy. Keep it simple. Mother Earth is doing just "fine". Mankind will someday just "go away" like every other living thing has before. Short of blowing ourselfs up a little early mankind will change nothing. We are not that "BIG".

I bet that's what cyanobacteria said, and they're considerably smaller than humans. Yet they were responsible for about the most profound atmospheric change in the earth's history. And the earth still hasn't recovered from this "pollution", even after 2.5 billion years!

So, does Earth care? Or does man care?

Likely not, since we (mammals and other animals) have evolved to depend on cyanobacteria pollution. I'm certain the earth doesn't care what happens.

However, my point is that life - even the smallest and humblest of life, has radically altered the earths atmosphere in the past with lasting effects (in this case 2.5 to 3.3 billion years of lasting effect). Obviously your hypothesis that humans cannot have lasting effect on the earth because of our size is mistaken at best, and dishonest at worst.

But the energy industry IS big. You haven't done the math yet:

- Humans produce today 24 billion metric tons of CO2 PER YEAR.
- The whole earth atmosphere has 3,000 billion metric tons of CO2. Time to do some math!

http://volcanoes.usgs.gov/Hazards/What/VolGas...
http://en.wikipedia.org/wiki/Carbon_dioxide

- CO2 levels have risen 35% since pre-industrial age, and this level has not been seen since at least 400,000 years.

We are that "BIG". The question now is if we are "big" enough to reverse what we have done.
