But this is more of a debate... about the greenhouse effect/global warming. First of all, i just wanna say that yes there is global warming happening, HOWEVER, we are not doomed to destroy earth if we do not alter our daily lives. Basically this mindset i am in right now has started since the middle of winter in the great state of florida. Northern Florida. Anywho, since it is northern florida our trees shed their leaves (cept the pines of course and palms), and regrow them in spring. This winter however was warmer, and our trees did NOT shed their leaves. I dont want to be ignorant but it seems like i am the only one that has confidence in our planet's way of rebalancing itself. If the temperatures continue to increase the trees will not shed their leaves, and if this does not help, when the heat gets too much for when the trees around the northern hemisphere and around Canida's latitude which is in fact 3/4 of the trees in the world, to not shed their leaves, we will have less CO2.

➔ Global Warming
you know what else probably didn't happen, if it was warm enough the trees did not shed their leaves??
plant pathogen lifecycles weren't interupted by the cold winter weather. guess what happens when that occurs too often.
Plants produce oxygen, they also exhale CO2, they don't vacuum all of the greenhouse gases out of the air.
there are still far more greenhouse gases other than CO2.
one other thing to note...CO2 level of over 600ppm have shown to be a very ugly situation for plants. currently we sit around 400ppm(and rising) which in the range of their maximum beneficial parameters.
what this means, is that as long as the concentration doesn't reach over ..565ppm(i believe the exact number is), plants will be able to handle slightly cooler climates, and mild droughts.

If the weather gets too warm for the trees to lose their leaves, those trees will die. They need their regular seasonal cycle to live. As global warming continues, warm weather trees will increase their range northward, and trees which require cold weather to live and produce will find it harder to survive. Orange juice is tasty, but I would miss maple syrup if there were no place left cold enough for the maple trees to do their thing. The issue is not whether the planet can rebalance itself; the planet will adapt to changes and evolve to meet challenges. The real issue is whether that rebalancing will happen in a way that supports human life. That's not so clear. Increased incidents of melanoma, decreases in fish populations, and increased cases of asthma are just a few of the problems which indicate a world increasingly hostile to human habitation.

I'm in North Florida as well and it's WAY too hot. The Emerald Coast never cools off except for maybe 30 days a year in which it drops below 60 degrees, even for just a few hours.

wel sir you have just outlned your observations about the changes that are happeneg to the climate of our planet Earth.
It is not only the shedding of the leaves and having less O2 to breathe, but this small increase in the temperature has led to a considerable change in the habitat of the other inhabitants of the this planet ... the animals who have been observed to change to other suitable places, only there are no places.. thanks to us humans.
And earth self regulating its climate, wel that may be true, and eventually that may happen but at what cost, no body is sure about. It can be the total anhalation of the human race or all the life forms living.
This is a thought that has to be pondered at lenght.

Two points.
Plants are not remotely close to keeping up with our emissions. Even a large increase in plants won't do it.
Look at this graph.
http://scrippsco2.ucsd.edu/graphics_gallery/mauna_loa_record/mlo_record.html
The little squiggles are nature doing its' thing. CO2 falls a bit during summer when plants are active, and rises during the winter. The huge increase is us, burning fossil fuels.
James Lovelock is a respected scientist who shares your belief in the power of Earth to repair itself. He's written a series of acclaimed books about it, calling Earth "Gaia", in reference to it's ability to do that.
But the scientific evidence about global warming has changed his mind about the Earth's ability to cope with that. So he wrote a book "The Revenge of Gaia" which is a passionate plea for massive construction of nuclear power plants to reduce global warming. It's an amazing change for him.
He's joined a large majority of scientists who believe we're in for a very bad time (no, it's not the end of the world) if we don't take action on this.

That is a very interesting observation. I agree that the planet is able to re-balance itself to a certain extent. Some of the impacts though are irreversible. Polar caps are melting, sea levels are rising, and with the climate changes, entire species can be lost.
Also, I believe we are able to damage the planet at a faster rate than it can recover.

QUESTION IN RESPONSE: If we are having a global warming/greenhouse effect and this has been going on for decades -- tell me WHY they spent 20 years 60 70;'s screaming we were going into another ICE AGE?

This is not an answer.
I agree that it will not a a catastrophe when the climate warms.
