Those who do will surely suffer, since GW is predicted to reduce world net food crop output in several ways: droughts, floods, heatwaves that kill plants; land loss from sea rise; no irrigation in glacier - fed rivers after glaciers melt in a few decades — putting 40 % of India & China at starvation risk; crop loss due to increased pests (weeds & bug); fish decline from several GW factors; there's probably more.

With more carbon dioxide in the air, plants grow better in warmer and cooler temperatures and wetter and drier soils, make better use of soil nutrients, and resist diseases and pests better, increasing their fruit production, expanding their range, and greening the earth.

Current farming methods erode and degrade topsoil, but we could reverse that by adopting methods that are less disturbing to the soil and plant roots and by more use of cover crops or «green manures» that add organic matter to the soil, increase soil fertility and water retention, and reduce pests and diseases.

The increase in PS would slow as the plants reach maturity.

Increased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge; there are already examples of earlier arrival and increased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is incIncreased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge; there are already examples of earlier arrival and increased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is incincreased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is incincreased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is increasedincreased.72
