It's not Global Warming, it's Ocean Warming
"Research shows that there was "a sudden and dramatic rise" in carbon dioxide in the Earth's atmosphere at the dinosaur extinction of 65 million years ago. A recent report attributes the rise in CO2 levels to an asteroid impact. See http://news.bbc.co.uk/1/hi/sci/tech/2038599.stm"
"I disagree. I think today's rise in CO2 levels can be attributed to our warming oceans. After all, the oceans are known as a carbon dioxide "sink," especially when the water is cold."
"But as the water warms up, it releases CO2 into the atmosphere. This happens in much the same way that a warm bottle of home-brewed root beer will release CO2. And if you give that CO2 no way to escape, the bottle will explode."
"We've got it backwards. We've got cause and effect in reverse."
"The CO2 is not causing global warming. Instead, our warming oceans are releasing CO2 into the atmosphere."
"It's not global warming, it's ocean warming, and it's leading us into an ice age."
I'm not sure, but I think most of the CO2 in the oceans isn't dissolved gasses, but is Calcium Carbonate. Clamshells, limestone, various diatoms.
