Anthropogenic climate change will mean an increased average temperature for the oceans and possible changes in current systems that could locally amplify or reduce warming and can alter nutrient cycling resulting in changes in the amount of nutrients available for the growth of phytoplankton, the plant plankton that are the base of the food chain.
But the evidence shows this can't be true; temperature changes before CO2 in every record of any duration for any time period; CO2 variability does not correlate with temperature at any point in the last 600 million years; atmospheric CO2 levels are currently at the lowest level in that period; in the 20th century most warming occurred before 1940 when human production of CO2 was very small; human production of CO2 increased the most after 1940 but global temperatures declined to 1985; from 2000 global temperatures declined while CO2 levels increased; and any reduction in CO2 threatens plant life, oxygen production, and therefore all life on the planet.
The warming of approximately 0.1 — 0.2 °C per decade that has resulted is very likely the primary cause of the increasing loss of snow cover and Arctic sea ice, of more frequent occurrence of very heavy precipitation, of rising sea level, and of shifts in the natural ranges of plants and animals.

Roger disputed that carbon (as CO2) caused any warming, that honest, unaltered science thought CO2 to be the consequence rather than the driver of temperature increases, that increasing CO2 in the air was sourced by natural phenomena rather than mostly man - made, and that to decrease CO2 to levels required by regulation would start to starve plants, making more folks on the planet to starve accordingly.
But even without warming, an increase in carbon dioxide should itself accelerate growth rates of plants.
