Few if any doubt the scientific fact climate change affects agriculture with droughts and floods, but agriculture is also one of the main driving forces behind climate change. Both factors have a very serious negative effect on CO2 emissions. Agriculture and lifestock farming alone are responsible for ±20% of global greenhouse gas emissions. Mitigating CO2 measures like planting forests and using biomass, while sensible to a point, can use up scarce agricultural land, thus push up food prices which in turn will affect economic growth and food security. A faster, cheaper and far more efficient solution to planting trees is the scale production of industrial hemp, the non-intoxicating form of cannabis.(See:

Alternative mitigation measures. for example, collectively eating less meat, combating agricultural waste, manure, and improving the crop yield per acre are equally important. Plants use sunlight to convert water and carbon dioxide into sugar and oxygen - a process called photosynthesis. However, farm crops use a very small percentage of the sunlight available to them. Just improving the process of photosynthesis, and increasing the yield of crops, can considerably expand agricultural production - not to exclude the development of crops that withstand drought better.
Land erosion, degradation, and desertification are leading to substantial amounts of agricultural land being lost. Using land more intelligently so that no new exploitation, e.g., such as irresponsible deforestation and draining of marshlands, is necessary are important aspects of climate change mitigation.
Combining these ideas and different disciplines together along and sharply reducing the use of fossil fuels will vastly improve the possibilities for a more climate-crisis-resistent world environment that does not warm up more than a living species threatening survival level of 2 to maximum 3 degrees Celsius by 2050.
