The UN has 193 member states. How many of those nations even have a
National Science Academy, and how many of their publications have you
read to make such a bald statement? Or did you simply read it somewhere?
Does it have any basis in fact?

'the warming has very little to do with the last 2000 years'

What on earth does that even mean? Didn't CO2 levels start to rise with
the Industrial Revolution? I'm pretty sure that happened in the last
2000 years (usually said to be between 1760 & 1840).

They're all stupid, I suppose and they don't know anything..........but
you and yours know ever so much more; don't you? Read the avalanche of
science and it will explain this to you. Ignore the avalanche of science
and focus on any tiny little part which might appear to back the denier
cause, without any real scrutiny, like the OP and you can convince yourself
of anything - as I've said.

You keep banging on about science, but what you refer to is more
correctly called 'climate science', which is mostly based on historical
and even archeological data as a basis for predictions of possible
future changes made using highly sophisticated computer models. Climate
scientists need to make use of old fashioned science such as physics,
chemistry and mathematics to enable them to make the models more
sophisticated. Climate science is still in its infancy and has some way
to go before it could be called mainstream. The route that climate
scientists take could have many changes of direction before we can be
sure that we fully understand it. These days we all think we understand
black holes, but apparently Stephen Hawking now says they don't exist.
