[LINK] Climate Change, The other point of View

[Frank O'Connor]

Nit picking.

It's effectively closed. Some atmosphere escapes into the vacuum that 
surrounds us. A lot of energy is reflected/exchanged back out by the 
effects of albedo and atmospheric exchange.Energy such as sunlight, 
meteors and asteroids even ... over which we have no effective 
control can enter the system.

And if we can't leave it whenever we like, or if doing so if 
prohibitively expensive (in wealth, energy, resources, technology 
etc) then it's even more effectively closed.

And if we have to live new steady states inside that system, then we 
should make sure that the steady states don't shift to violently ... 
into Ice Ages (Yay for the greenhouse gases!) or excessive Greenhouse 
warming that takes our species outside its comfort zone.
