US has more Trees now than in the 1700s.
okay, I will call BS on that one. The US used to have a huge forest from the east coast to the Mississippi river. Gone. I doubt the trees planted in the other areas compensate for that.
I am not a tree hugger by any means. The majority of our CO2 >>> O2 cycle is conducted by blue-green algae in the oceans anyway. But they look pretty.
interesting bit about the blue-green algae producing more O2 than trees. if the ocean temps rise enough to disrupt this, then the CO2 levels would rise (because of lack of the sufficent quantity of algae to process it), and this CO2 contributes to greenhouse effect no? i'm unsure how hot the ocean would have to be in order to kill off the algae though. certainly, the temps raising would have potential effects on currents and breeding of sea animals so that impact could be a problem.
but then again, what does it take really to increase the temp of the oceans? i would think that's a very tough thing to do over a short time.
my guess is that most of the perceived climate changes we are experiencing now are due to cyclic behaviors due in larger part to the orbit of our planet around the sun as opposed to the atmosphere. in the industrial revolution days, there were huge problems with polution yet we didn't experience climate changes based soley on these factors. In fact, Pittsburgh was so black with soot that noon looked like midnight on a new moon - completely black - and that wasn't so long ago.
i can kind of see both sides of the global warming argument but i still have my doubts as to the true motives of the Goracles. my gut tells me that they are in it for the money and not to save the earth.
Here is the fun thing about raising water temps: Microbes love warmer temperatures... well, they still reproduce in 37
o C/100
o F temps. But, as the water temp rose, the algae would be able to spread more into the northern and southern areas currently too
cold for the algae to survive. So, as CO2 rises, the water gets warmer, the algae is able to spread more, more CO2 is stripped from the atmosphere and converted to oxygen, temperatures fall. The oceans are a temperature regulator for our planet in more ways than one.
I will confess, however, that I do not know what time scale we would be talking about. It may be quickly, it may not. I am not a microbiologist, but I did bring this subject up with my microbiology professor; I just forgot to ask about time frames.
What everyone also forgets is they assume we are leaving the "normal" phase and getting hotter. The earth temperature is cyclic. We have been coming out of a mini-ice age. There is no "normal" state that the earth is usually enjoying.
And you are correct; many people usually try to discount one of the largest factors; the Sun.
