They were represented to purport a direct causal fit, suggesting that increased atmospheric CO2 concentrations produce warming.
If carbon dioxide (CO2) emissions continue at current rates, atmospheric CO2 concentrations are expected to double by 2050.
This is no surprise since plants and animals evolved when CO2 concentrations were about 10 times larger than they are today.

Plants do so much better with more CO2 that greenhouse operators often increase the CO2 concentrations by factors of three or four to get better growth.

It said the UK would have to make substantial cuts in carbon dioxide (CO2) by mid-century to be part of the global coalition on stabilising atmospheric CO2 concentrations.
Not even a worldwide depression that permanently lowers global economic output and emissions to, say, 1970 levels, would stop CO2 concentrations from rising over the remainder of the century.

For example, according to all GCM simulations, increased CO2 concentrations should have produced an increased tropical warming trend with altitude, which is contrary to what balloon and satellites observations actually show.

Forget that even the director of the East Anglia University Climate Research Unit, Dr. Phil Jones, a principal ClimateGate figure, admitted that despite higher atmospheric CO2 concentrations there has been no statistically significant warming since 1995.
Despite advances in understanding the impacts of elevated CO2 concentrations on a wide range of marine organisms, we are still unable to make meaningful projections of impacts on marine ecosystems and fisheries as a whole, or to identify thresholds beyond which marine ecosystems may not recover.
Concentrations of CO2 reached 389 parts per million in 2010 - the highest such concentrations since the start of the industrial era in 1750.
It suggests that CO2 has now reached concentrations of 390.9 parts per million, or 140% of the pre-industrial levels of 280ppm.
Concentrations of CO2 in the atmosphere currently stand at 385 parts per million (ppm) and are rising at a rate of two ppm per year.
Atmospheric concentrations of CO2 equivalent (carbon dioxide and other greenhouse gases) reached 430 parts per million last year, compared with 280ppm before the industrial revolution.
Concentrations of atmospheric CO2 have risen to 383 parts per million.
CO2 is a colorless and odorless gas, exhaled at high concentrations by each of us, and a key component of the biosphere's life cycle.
