The Earth does this, mostly by absorbing the CO2 into the oceans generating growth spurts of algae which then dies and falls to the ocean bed and is taken out of the carbon chain for a great many thousands of years. Unfortunately, the Earth cannot cope with the increasing volumes of CO2 being spewed into the atmosphere by mankind. But the problem may not be irreversible if carbon emissions are significantly reduced.

A shitload of atmospheric CO2 can be absorbed by the oceans, but only sometimes, depending on how it's got to the atmosphere?

No. A shitload of CO2 /occasionally/ spewed into the atmosphere can be absorbed by the oceans over a period of time. A shitload of CO2 /constantly/ spewed into the atmosphere cannot be absorbed by the oceans unless the spewing is halted or significantly reduced. Even then it may take decades, even centuries to re-balance CO2 levels.

So any effect being seen now is actually nothing to do with current emissions, but is due to emissions decades ago - back when coal was a popular heating and electricity generating fuel? Current emissions won't start to affect for decades?

Clearly not. >So any effect being seen now is actually nothing to do with current >emissions, but is due to emissions decades ago - back when coal was a >popular heating and electricity generating fuel? Current emissions won't >start to affect for decades? CO2 levels in the atmosphere are 35% higher than at the start of the Industrial Revolution and rising at an accelerating rate. Sea levels are rising at about 3mm per year, and accelerating. Emissions now make a difference now and will continue to do so for many decades. |
