I think at best you could say that some black market activity isn't governed by organized crime. Either way, we have come a long way from "Markets by definition..."

You seem very certain about a topic that you appear to understand only superficially. You have neglected thermal expansion.

Could you give me an example? Game theory suggests that this would fail on any large scale.

Assuming you have a good account of undiscovered repositories, which I think is probably unlikely, how do you know that 1000 ppm is quite safe? Do you have any evidence to support this claim?

I'm not so sure that's a bad thing.

By what definition? Are you referring to barter? Any more complex market requires governance. The market based solution that I favour is a revenue neutral carbon tax. Income tax and sales tax would be reduced (which is good because why are we taxing behaviours that we want to encourage!) but the price at the pump would increase. A relatively modest RNCT was introduced in British Columbia and it seems to be working quite well.

Agreed. We need to proceed with caution. We're better equipped to tackle this if we're rich. Let's plan to stay that way.

The big problem is that there is much more fossil fuel available than we can safely burn. Just waiting until we run out (or diminish stocks to the point that they become prohibitively or even relatively expensive) is not really a solution.

It would be nice if they provided sources, but there is nothing really controversial in the article. The article from 2007 noted that arctic sea ice was diminishing faster than any models had predicted. That has not changed since 2007: http://www.arctic.noaa.gov/rep... .

I'm intrigued. What is the best way to accomplish this? I'd advocate a market based solution (but not cap and trade), but even that would require government intervention. Is there a better way?

Who gets to choose which to follow and which to reject? How about these stories about how the early christian church redistributed wealth. Abhorrent or tenet?

"No one claimed that any of their possessions was their own, but they shared everything they had. With great power the apostles continued to testify to the resurrection of the Lord Jesus. And God’s grace was so powerfully at work in them all that there were no needy persons among them. For from time to time those who owned land or houses sold them, brought the money from the sales and put it at the apostles’ feet, and it was distributed to anyone who had need.”

Or this:

And all that believed were together, and had all things common; And sold their possessions and goods, and parted them to all, as every man had need. And they, continuing daily with one accord in the temple, and breaking bread from house to house.

Or this:

Now a man named Ananias, together with his wife Sapphira, also sold a piece of property. With his wife’s full knowledge he kept back part of the money for himself, but brought the rest and put it at the apostles’ feet.

Then Peter said, “Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit and have kept for yourself some of the money you received for the land? Didn’t it belong to you before it was sold? And after it was sold, wasn’t the money at your disposal? What made you think of doing such a thing? You have not lied just to human beings but to God.”

When Ananias heard this, he fell down and died. And great fear seized all who heard what had happened. Then some young men came forward, wrapped up his body, and carried him out and buried him.

About three hours later his wife came in, not knowing what had happened. Peter asked her, “Tell me, is this the price you and Ananias got for the land?”

“Yes,” she said, “that is the price.”

Peter said to her, “How could you conspire to test the Spirit of the Lord? Listen! The feet of the men who buried your husband are at the door, and they will carry you out also.”

At that moment she fell down at his feet and died. Then the young men came in and, finding her dead, carried her out and buried her beside her husband. Great fear seized the whole church and all who heard about these events.

The consequence of possessions was death. Jesus even suggested eternal damnation was the ultimate result of wealth. Are these stories an account of how the early church was horrible, or is this religious tenet?

Here is what the IPCC actually said of sea ice 25 years ago: On the basis of current simulations, it is not possible to make reliable quantitative estimates or the changes in the sea ice extent and depth It should be noted that the models considered here neglect ice dynamics, leads, salinity effects, and changes in ocean circulation.

Don't suffer from single study syndrome. Look for a consensus rather than focusing on one paper or another. The IPCC is a great resource for understanding the consensus.

I think you are confusing sea ice area with continental ice volume. As the volume melts it deposits fresh water near the surface. Fresh water freezes more readily than salt water. So you can have the sea ice area increase even while overall volume decreases.
