HEMP-CRETE :0)

Isn't Solar output a factor, I hear it has increase as part of a cycle recently. Why isn't this mentioned as a factor? I don't want to pay more taxes to rich assholes for this when there's no proof that we are the only reason.

@MrROTD Solar energy varies each year, and may have impact on global temperatures over longer term, but in meantime we do need to manage CO2 levels.

Patrick Dixon you are awesome

The Soviets used Portland cement free CO2 free concrete in the 1960s to build entire apartment buildings. The buildings concrete was recently studied and found to be sounder than the day it was cast.

I would think 50 years of data would be enough.

Fact human make less than 5 percent of all CO2, Water Vapor make up 95 percent of all green house gases, in 1200 it was warmer and had lower CO2, and best of all the sun is the biggest factor of all. Look at all the sides because I just derailed human CO2 affect into nothing to worry about worry about.

Water vapor isn't a green house gas... Maybe you should take a proper English course.

Realclimate

Water vapour is a major contributor to the greenhouse effect.

And

The overlaps complicate things, but its clear that water vapour is the single most important absorber (between 36% and 66% of the greenhouse effect), and together with clouds makes up between 66% and 85%.

To top that off, the quote, "out of context" emails form climategate are real.

[MrROTD]

@pickford7812 yeah water vapour scatters and reflects light coming in from the sun, what are they trying to teach us?

7% thats amazing, I had know idea setting concrete released that.
