Nearly all plants have increases in biomass (dry weight) in response to a higher concentration of atmospheric CO2 (more CO2).
Nearly all plants have an increased rate of photosynthesis in response to more CO2.
Forest growth rates around the world have increased since the Industrial Revolution in response to more CO2 in the air
Earth’s 'greening' has been observed from satellites, in spite of fires, disease, pest outbreaks, air pollution, deforestation, and climate change.
World agricultural productivity increased a lot over the last three decades of the twentieth century, from new cultivation techniques, slightly warmer temperatures, and higher CO2 levels.
Rising CO2 increases plant growth, which reduces the serious environmental problem of topsoil erosion.
Rising CO2 causes plants to reduce the time their stomata are open to absorb CO2, which reduces water loss when the stomata are open = less fresh water required, even as they grow faster.
Rising CO2 increases agricultural crop yields by increasing concentrations of plant hormones that stimulate cell division, cell elongation, and protein synthesis.
Rising CO2 increases flower pollination, and nectar production, leading to increases in fruit, grain, and vegetable yields.
Rising CO2 causes many plants to grow larger, and their more extensive root systems allow them to extract greater amounts of minerals from the soil.
If air temperatures rise, that would extend the growing season, causing plants to grow even more.
Rising CO2 helps many plants use water more efficiently, reducing stress from less-than-optimum soil moisture.
Rising CO2 increases weed growth too, but not as much as the growth of non-weed plants.
Rising CO2 increases production of natural substances in plants that repel insects.
Rising CO2 helps plants overcome stress from the buildup of soil salinity from repeated irrigation.
IPCC’s forecasts of future species extinction are based almost entirely on computer model projections that contradict real-world observations.
Studies show global warming either expands animal habitats, ranges, and populations, or has no observable effects.
Aquatic life has survived climate oscillations that have persisted for millions of years.
The natural variability of ocean pH levels is often much greater than the change in pH levels forecast by the UN's IPCC.
Natural fluctuations in ocean pH and CO2 levels results in living populations acclimatized to variable pH.
Results from laboratory-based studies of lower ocean pH levels are quite different than what's observed in nature.
Rising temperatures and atmospheric CO2 levels do not pose a significant threat to aquatic life because many species have considerable tolerance to temperatures and CO2.
No extinction of coral reefs will occur from rising seawater temperature, because warming enhances coral calcification.
Warmer temperatures lead to a decrease in human deaths from cardiovascular disease, respiratory disease, and strokes.
The evidence of this is from research conducted in every major country of the world.
In the United States Between 3% and 7% of the gain in human longevity over the past three decades was due to people moving to warmer southern states.
