“The ocean plays an important role in the climate system by regulating the amount of CO2 in the atmosphere. Carbon dioxide entering the deep waters is removed from interaction with the atmosphere for periods of hundreds of years. A significant fraction of the excess crbon dioxide released by man’s activities enters the deep waters of the ocean and plays no further part in global warming over century timescales.” (Ocean Carbon Cycle Modelling Group)

It's not the record high temperatures that are supposed to indicate 'global warming', it's the average daily temperatures that are meaningful.

Brilliant point.

Just to add to this, for amphibians, which I work with specifically, it is the mean minimum temperature that most effects population movement and breeding since they are nocturnal.

And, min temps have been climbing faster than max temps.

I thought it was the decrease in the polar caps that is determining the global warming effect..I wouldnt worry too much about what Bush or anyother politician says...I mean how many times has Medicare really been "fixed" because a politician said that was on their agenda? Pollution is still a problem, rainforests are still deminishing, hunger in the U.S. is still a problem along with high unemployment. More than likely it is just an idea being kicked around in the Oval office and will never even be implemented.

First of all, forgive me for not having read through this thread before posting.

Increased CO2 in the oceans would result in decreases in the pH levels (the measure of acidity) of seawater

Only in the water mass it was injected in.

As atmospheric CO2 diffuses into the upper layers of the water, it inhibits the ability of shellfish to form shells and causes coral reefs to dissolve.

Seibel is obviously a biologist and not much of an oceanographer. At the injection depths, there is a high solubility of carbon dioxide (temperature and pressure controlled). The Atlantic bottom water that this injection would occur in, and therefore contain the dissolved carbon dioxide, would not diffuse up. This water does not mix across the isopycnals created by the density differences of the water masses overlying it. The diffusion coefficient is miniscule.

High unemployment? We have the lowest percentage of any country in the world.We have ten million Mexicans finding plenty of work ......... The current rate is lower then the average for the 1970s 1980s and 1990s......its currently lower then most of the Clinton years. Hunger in the USA? "Crack" parents maybe, but hunger? The rest of the world defines "hunger" somewhat differently the Democrats.....

Lol kalbreath, take me to Wonderland with you next time you go back! And you still haven't learned how to make one more full stop. I know, low punch, but I am trying to be politically correct.

I am not assaulting you, I'm just questioning your way of thinking, and _perhaps_ your intelligence.

I suggest you read some non-main-stream media for a change.

Let me ask you something. Are you white middle/higher class male? If so, I rest my case.

no idea if this has been said before, but we do have the means to save the planet, its called trees and we need to stop cutting them down and putting in new ones!

I'm not disputing the fact that the ocean plays a significant role in all our lives however trees during (photosyn... can't for the life of my remember how to spell it) and converts cardon dioxide to oxygen!

So there we go, then all we have to do is cut down on all the carbon dioxide going into the air then bobs your uncle!

Correct me if I'm wrong but don't the kelp forests of the oceans produce nearly 50 percent of the world's oxygen? Taken together, the rain forests only produce 20-30% of the world’s oxygen.

Actually its about 95% from plankton . Ever wonder why there is not less oxygen in the Winter over land , when the trees are devoid of leaves? Forrests have very little effects on the O2 levels of the earth. Forrest do however have a great cooling effect.

Actually, no one knows the true relative amounts of different atmospheric oxygen sources. The current general concensus seems to be that about 30% of total atmospheric oxygen comes from the oceans while 20% comes from equatorial rainforests.

No, the atmosphere is not static.

Forrest do however have a great cooling effect.

The truth is that deforestation means a cooler earth, because deforestation increases albedo.

BZZZZZZZZZZZZZZZ... (i'm holding the buzzer). :wink:

Actually, they do know and the concensus seems to be that about 50% of the world's oxygen is from the ocean and 20 to 30% from all rain forests combined. Also the earth's oxygen level is falling every so slightly as the carbon dioxide concentration increases about 1.5 parts per million (ppm) each year. The carbon dioxide increase/oxygen decrease is due to deforestation and burning of fossil fuels. If deforestation is contributing to higher CO2 levels in the atmosphere, the increased "greenhouse effect" would lead to warmer temps.
"The changes of surface albedo due to deforestation are not significant and the main effect of deforestation originates in changes in the hydrological cycle. Therefore, deforestation leads to decreased latent heat flux and increased surface air temperatures".

I don't think they will go through with it but if they do I would Vote No that is for sure. Global Warming is something we caused but why try to do more damage to stop it. If something is going to happen it is going to happen for a reason. why do it. Why would some one want to kill off life. the CO2 will also affect us in ways too. My 2 cent. No No No on this Idea. :x

Sorry, that is incorrect. It is not known.

"The changes of surface albedo due to deforestation are not significant and the main effect of deforestation originates in changes in the hydrological cycle. Therefore, deforestation leads to decreased latent heat flux and increased surface air temperatures".

This is also not correct. Global deforestation has the capacity to decrease surface air temperatures quite rapidly.
