A Climate Denial Crock of the Week video does just that in debunking the CO2 plant food argument. We could discuss the scientific finer points of global climate change and the unlimited effects it could have on global plant growth all day. But even if "CO2 fertilization" occurs, weeds proliferate in tandem with crops, which would only increase the global cost of agriculture. Presumably the CO2 as plant food enthusiasts offer their argument in an effort to demonstrate the resulting agricultural advantages. To what extent will this happen? For one, the increased density of forest vegetation could increase the risk of wildfires, which have reared their ugly heads in California all too often in the past few years, wreaking devastating damage. Suppose, however, that CO2 does prime plant growth in the world at large. This causes extreme weather in certain geographic locations only sporadically, with overall, balanced rainfall drastically reduced. Another effect of global climate change is erratic precipitation patterns. With the global increase in temperature caused by the various factors affecting our climate's balance, increased evaporation means decreased soil moisture. Arguably the most important of these elements is water. While CO2 is an important element that stimulates plant growth, the planet's flora requires a cocktail of elements to maintain its health. A rise in CO2 levels is not the only consequence of climate change, and it is these other effects that have had and will have more abiding adverse effects on plant growth around the world. However, the globe is not a controlled environment, and it’s incredible sensitivity to a variety of factors is something that is often taken for granted when such narrow arguments are proffered. In closed, controlled environments, like greenhouses and plant nurseries, an increase in CO2 does indeed spur plant growth. The basic plant food argument is that since plants need CO2 to grow, more CO2 means, by proxy, more sustained and robust plant growth globally.Ī quick look at the science behind this argument demonstrates its inherent weaknesses. House Subcommittee on Energy and Environment hearing in 2009. John Shimkus of Illinois made famous the CO2 as plant food argument during a U.S. And so, too, does ignorance and a little bit of politicking feed inane misconceptions. 2023 SkS Weekly Climate Change & Global Warming News Roundup #3ĬO2 is Good for Plants: Another Red Herring in the Climate Change Debate Posted on 1 July 2010 by Mariana AshleyĬO2 feeds plants.Input to USDA about how to allocate IRA climate-smart agriculture funds.had 18 different billion-dollar weather disasters in 2022 Checklist: How to take advantage of brand-new clean energy tax credits.Skeptical Science New Research for Week #4 2023.2023 SkS Weekly Climate Change & Global Warming News Roundup #4.The other ‘big one’: How a megaflood could swamp California’s Central Valley.2023 self-paced run of Denial101x starts on February 7.Skeptical Science New Research for Week #5 2023.Cranky Uncle could use your help to learn more languages!. 2023 SkS Weekly Climate Change & Global Warming News Roundup #5.Clean energy permitting reform needed to boost economy, protect climate and burn less coal.Myths about fossil fuels and renewable energy are circulating again.Skeptical Science New Research for Week #6 2023.2023 SkS Weekly Climate Change & Global Warming News Roundup #6.Dana Nuccitelli wins environmental journalism award.Skeptical Science News: The Rebuttal Update Project.Skeptical Science New Research for Week #7 2023.2023 SkS Weekly Climate Change & Global Warming News Roundup #7.Climate change is increasing the risk of a California megaflood.At a glance - What were climate scientists predicting in the 1970s?.Skeptical Science New Research for Week #8 2023.2023 SkS Weekly Climate Change & Global Warming News Roundup #8.Which state is winning at renewable energy production?.At a glance - What has global warming done since 1998?.Home Arguments Software Resources Comments The Consensus Project Translations About Support
