So, maybe we can do something about the moon.

To those of you who say, why should I be concerned about something that might happen in 50-100 years? Be serious.
When you look at all the money they are throwing at Iraq, and the scant attention they are paying to climate change, it makes you wonder about the sanity of those folks in D.C. Fortunately, it looks like it isn't too late to do something to slow the changes down. I wonder if it isn't possible to eat or modify some of that CO2 up there in the atmosphere? I know plants eat CO2 and give off O2 and CH4. One concern I have near-term is how the media handles this. Fear seems to be one of their tools to get attention, and that could get out of control. They did that this year with hurricanes in Florida, and now insurance companies are getting unreasonable there. Right now, I think we are still mainly seeing cyclical weather swings which aren't connected to greenhouse gases. But the politicians have to act--now. That will mean higher energy prices. There will be a price to pay. The corporations are already factoring it in. |
Thousands of Weather Ballons covered with moss. Think about it. Seriously.

Aurel, This calculation says 10cm per degree.:
Water has a small but nonzero expansion as it warms. The expansion is approximately 2E-4 per degree of warming, at the temperatures of the upper ocean. To convert that into a sea level change, we need to multiply by the amount of warming and the thickness of the ocean that gets warmed. The amount of warming is the subject of the climate modelling. Let's consider a warming of 1 K for simplicity. The central question for the oceanographers is then how deep a layer of the ocean gets warmed. This is a difficult question. The challenge lies in the fact that the atmosphere heats the ocean at the top. Obvious. Not obvious is that this impedes warming much of the ocean. Warm water is less dense, so tends to stay at the surface of the ocean. If this were all that happened, only the layer of ocean directly warmed by the sun would be affected, about the top 100 meters. There is mixing within the ocean, which tends to force some of this heat further down. Balancing that effect is the fact that water from the deep ocean (which is cold) generally rises through most of the ocean basin. So mixing brings down warm water, and upwelling brings up colder water. Let's assume that the thickness that gets warmed is approximately the same as that which is already warm. That is approximately 500 meters. For the 1 degree warming, we then have 500*2E-4*1 meters of rise, or 0.10 meters. The time scale over which this occurs is the length of time it takes to mix the upper ocean, and is on the order of decades. |

Wait wait wait . .. I thought this was Global Warming. What the hell is all this about only Ocean warming?
. . . and if it's the Globe that is warming, then shouldnt this big sphere expand thermally? . .. and then what would that do to ocean levels? :cool: |
Oh, and when the glass of ice water expands, the water level falls . . even if it was clear glacial ice in the glass. :rolleyes:

You have to pay extra for glacial ice, it has special properties they say. While it's not so special as Ice 9, it's probably something like Ice 8.5.
