The lines of evidence and analysis supporting the mainstream position on
climate change are diverse and robust — embracing a huge body of direct measurements by a variety of methods in a wealth of locations on the Earth's surface and from space, solid understanding of the basic physics governing how energy flow in the atmosphere interacts with greenhouse gases, insights derived from the reconstruction of causes and
consequences of millions of years of natural climatic variations, and the results of computer
models that are increasingly capable of reproducing the main features of Earth's
climate with and without human influences.

«It could mean our higher limit of warming is now even higher, depending on the
model, which means serious

«Uncertainty» about whether or not something (very costly), which we do (in the «uncertain» attempt to change our
climate from an «uncertain»
model - generated threat) will have «uncertain» unintended negative
consequences, which could be much more severe than the «uncertain» threat we are attempting to mitigate against in the first place, seems to ba a reasonable justification for NOT doing this mitigating action.

My bottom line is that while the global
climate models, when run with added CO2 and other greenhouse gases, show that this is a warming effect, they are inadequate tools to assess the

climate prediction will collapse.
And to make this realistic pictures, a simple scaling is often not adequate to depict all

One of the
consequences is that if you run multiple computer simulations of earth's

model runs do.
