Human Emissions Saved Planet
Over the past 150 million years, carbon dioxide had been drawn down steadily (by plants) from about 3,000 parts per million to about 280 parts per million before the Industrial Revolution. If this trend continued, the carbon dioxide level would have become too low to support life on Earth. Human fossil fuel use and clearing land for crops have boosted carbon dioxide from its lowest level in the history of the Earth back to 400 parts per million today.
At 400 parts per million, all our food crops, forests, and natural ecosystems are still on a starvation diet for carbon dioxide. The optimum level of carbon dioxide for plant growth, given enough water and nutrients, is about 1,500 parts per million, nearly four times higher than today. Greenhouse growers inject carbon-dioxide to increase yields. Farms and forests will produce more if carbon-dioxide keeps rising.

Well actually, no I didn’t know what you meant if it was something other than what you said:
“The earth is 2/3 water i.e. deep oceans”
If you hadn’t added the “i.e. deep oceans” I would have known what you meant. But by adding depth, a third dimension, you were implying that the oceans were so deep that the earth was made up of 2/3 water, not just two dimensional area.
No, I wasn’t really arguing.
It is just that so many claim that since the sun’s output only varies about 0.1% through the normal 11 year solar cycle that it couldn’t possibly be responsible for any significant change on Earth. My only point is a lot more is going on than just the total energy output changing, particularly with the solar winds.
Oh my God.
Please avoid me at parties.
Actually, never mind. You don’t sound as if you’ve been to one.

Words matter.
Nice how you go personal and insulting...
Don’t worry, I don’t care to know you either.
