CO2 concentrations in 2020 would be about 410 ppm (and rising over 2 ppm a year). Around 2050, we’d be at 5 billion tons and very likely over 450 ppm, rising over 1 ppm a year.

Results: Relative to 600 ppm, at 1,000 ppm CO2, moderate and statistically significant decrements occurred in six of nine scales of decision-making performance. At 2,500 ppm, large and statistically significant reductions occurred in seven scales of decision-making performance (raw score ratios, 0.06-0.56), but performance on the focused activity scale increased.
The Venusian atmosphere supports opaque clouds of sulfuric acid, making What’s the big deal about 400 ppm? Well, the 'safe' level of CO2 in the atmosphere is considered to be 350 ppm, and the last time Earth experienced levels that were consistently this high was roughly 4 million years ago. That means humans have literally never experienced CO2 like this before. To convert from ppm to gigatonne of carbon, the conversion tables of the Carbon Dioxide Information Analysis Center advise that 1 part per million of atmospheric CO 2 is equivalent to 2.13 Gigatonnes Carbon.
