A few weeks ago we asked for constructive criticism and suggestions for a post on EverythingClimate.com.
Proposals have been compiled and are being taken up. Mike Dubrasich and Nick Stokes made some of the best suggestions for anyone wanting to go back and see what we’d like to do.
This week we want to see what we can do with the article Climate Change and Crop Production – All Climate

Pro: Climate change will lead to food shortages
Climate changes projected by global climate models are consistent with observed climate changes that affect agriculture (Chapter 2: Climate) .41,42,43 Climate change can adversely affect agricultural productivity at the local, regional and continental levels Animal production in certain regions is affected by both direct effects of climate change (such as increasing trends in day and night temperatures, changes in precipitation patterns and more frequent climate extremes, flooding and drought) and secondary effects (adverse effects). such as increased weed, pest and disease pressure, reduced crop and forage production and quality as well as damage to the infrastructure). While the effects of climate change on future agricultural production in certain regions of the United States remain uncertain, the ability of producers to adapt to climate change through planting decisions, agricultural practices and the use of technology can reduce the negative effects on production (► Chap . 21: Midwest, Case Study “Adaptation in Forestry”). 45
The risks associated with climate change depend on the speed and severity of the change and the ability of manufacturers to adapt to change. The severity of financial risks also depends on changes in food prices and levels of trade from local to global, as production and consumption patterns are likely to change due to climate change.10,46 Many countries are already seeing rapid increases in the price of staple foods. mainly due to production losses associated with more frequent weather extremes and unpredictable weather events. The United States is a major exporter of agricultural commodities 47 and any disruption to its agricultural production will affect the agricultural sector worldwide. Food security, which is already a global challenge, is likely to become even more of a challenge as climate change affects agriculture.48,49 Food security is determined by projected population growth and possible diet changes if the world tries to feed itself. further questioned By 2050, an estimated 9.8 billion people will be living. 50.51.52

Climate change threatens our ability to ensure global food security, eradicate poverty and achieve sustainable development. Greenhouse gas emissions from human activities and farm animals are a major driver of climate change, trapping heat in the earth’s atmosphere and triggering global warming.
Climate change has both direct and indirect effects on agricultural productivity, including changing rainfall patterns, drought, flooding, and the geographical redistribution of pests and diseases. The enormous amounts of CO₂ absorbed by the oceans cause acidification and affect the health of our oceans and those whose livelihoods and nutrition depend on them. FAO supports countries in mitigating and adapting to the effects of climate change through a wide range of research-based and practical programs and projects. This is an essential part of the 2030 Agenda and the Sustainable Development Goals.

Con: Food production is growing and is safe
As our planet warms up, global crop yields and crop yields around the world are setting new records almost every year. Not only globally, but also crop yields in the US continue to grow and set new records almost every year.
Longer growing seasons, higher temperatures and more atmospheric carbon dioxide create ideal harvesting conditions.
While the global climate is warming slightly, crop yields in the US and around the world are setting new records almost every year. The same applies to almost all other nations. Thanks in large part to longer growing seasons, less frost, more rainfall, and the fertilizing effect of atmospheric carbon dioxide, farmers are producing more food on less land so they can feed a growing world population.
Plant production facts: The global crop year 2019 brought a record production of the important cereal crops; Corn, wheat and rice. This builds on previous records set almost every year over the past decade. Virtually every major U.S. crop has had record acre yields in the past three years (latest data as of this writing in February 2020), with most of the top 10 years in acre yields seen in the past decade. For example, each of the three record high corn crops has occurred in the past three years. Each of the five record high rice yields have been achieved in the past five years. The past nine years have seen top 10 wheat yields of all time.
How Global Warming Will Benefit Plant Production:Global warming extends the growing seasons, reduces frost events and makes more land conducive to crop production. Global soil moisture has maintained the pace or has improved slightly as global temperatures have increased slightly. Greater evaporation from the oceans leads to more global precipitation, especially during the summer and fall seasons. In addition, carbon dioxide is very beneficial to crop production as atmospheric carbon dioxide acts as an air fertilizer. Higher levels of atmospheric carbon dioxide support plant growth and resistance to drought and heat. For this reason, greenhouses often pump in increased amounts of carbon dioxide.
