One of the most substantial climate changes in response to global warming is the increase in atmospheric water vapor content.

The present rate of increase of 0.7 ppm per year would therefore (if extrapolated to 2000 A.D.) result in a warming of about 0.6 °C — a very substantial change.

Lacis expressly rejects the IPCC's use of the word a «substantial» factor, and argues: «Based on this basic input data, the relevant physics is inescapably clear that the increase in atmospheric CO2 is indeed enhancing the strength of the terrestrial greenhouse effect, and thus causing global warming to happen — all directly attributable to human industrial activity.»

Whilst economic growth is projected to significantly reduce childhood stunting, climate change is projected to reverse these gains in a number of regions: substantial increases in stunting due to malnutrition are projected to occur with warming of 2 °C to 2.5 °C, especially in Sub-Saharan Africa and South Asia, and this is likely to get worse at 4 °C.
