Actually it's around 20% contributing towards the greenhouse effect from carbon dioxide, 50% - water vapour, 25% due to clouds and around 5% for
other gases.

So why aren't climate scientists a lot more worried about water vapour than about CO2? The answer has to do with how long greenhouse gases
persist in the atmosphere. For water, the average is just a few days.
This rapid turnover means that even if human activity was directly adding or removing significant amounts of water vapour (it isn't), there would be
no slow build-up of water vapour as is happening with CO2
What is certain is that, in the jargon of climate science, water vapour is a feedback, but not a forcing.
you said:
Water vapor is 99.999% NATURAL, so there is NOTHING you can do to stop Climate Change, and that's again without mentioning that
sequestration of CO2 means you are starving the green biomass of Earth, which also means less harvest, which means MORE STARVATION OF PEOPLE AND
ANIMALS...
We can prevent a runaway greenhouse effect by reducing the contribution by CO2. The plants and animals thrived before man-made CO2 emissions were
around, and the temperature rises this will cause would be the primary cause of drought, famine, etc.
I've call people ignorant when they ignore these basic scientific facts. It seems you call others ignorant because they choose not to believe in
your conspiracies, especially when you have so little facts to back it up.
What you are claiming as long-term benefits to high CO2 levels are only in fact short-term benefits, and once a threshold point is reached - it will
lead to far worser consequences which outweigh the positives.
This is analogous to recent research concluding that drinking a bottle of wine a day reduces chances of heart disease by around 1/3 - short-term
benefits, although later on a good chance of liver failure. Personally, I do not want the Earth to have liver failure so we can grow a few more crops
today!!!
You also seem to confuse natural climate change with man-made climate change, or rather just ignore the latter.
I used to think the theory of the sun cycles as being the major cause due to decreases in solar wind causing an increase in cosmic ray impacts, and
therefore an increase in cloud formation. But this theory has never being proven, yet it has been tested rigorously.
The Earth BENEFITS from having CO2, and throughout the entire lifetime of Earth the Earth has experienced 7-16 times as much CO2 in it's
atmosphere. Animal life, and plant life, as well as life in the oceans THRIVED with more atmospheric CO2, but people like you have been brainwashed to
believe the lie that CO2 is bad.
You do know you are living in a CARBON based world right?... You do know that ALL plant life thrives with higher concentrations of CO2
right?...
I didn't say CO2 was only good or only bad! - I understand both the positives and negatives of CO2. Thanks for the reminder that we are carbon
based, as you never know when someone might forget that!
You do realise that life thrived in an ecosystem with higher CO2 in the past, with levels that increased slower and so life adapted slower and so were
suited for that environment. In the modern day CO2 levels are increasing at an unnatural rate, and so this has unnatural consequences to life that
cannot adapt quickly enough to survive over a few decades.
Never mind if the polar bears and most animal life dies out, as the plants will thrive in Europe! WOW!!! You really are dense!!!
You know what is most interesting out of all of this - even if the human race became extinct, along with 99% plant life and animals in a mass
extinction. In millions or so years in the future, this may even lead to a different species to evolve and take it's place on Earth as the most
dominant species - but that isn't guaranteed if a runaway greenhouse effect takes hold. I doubt any new species could treat the Earth any worse than
humans are currently, so maybe the human race does deserve to go into the rubbish bin of history if we cannot treat planet earth and its occupants
with more respect.
