Review finds increased CO2 fertilization improves woody plant resistance to drought

[Illustrations, footnotes and references available in PDF version]
It is widely acknowledged that as the CO2 content of the air continues to rise, nearly all of earth's plants will exhibit increases in photosynthesis and biomass production; but climate alarmists periodically proclaim that future water stress will negate these benefits of atmospheric CO2 enrichment. In reviewing much of the pertinent scientific literature of the ten-year period 1983-1994, however, Idso and Idso (1994) determined that water stress will generally not negate the CO2-induced stimulation of plant growth. In fact, they found that the CO2-induced percentage increase in plant productivity was nearly always greater under water-stressed conditions than it.
