Dear Gwazah

Greetings

Climate change will affect agriculture through effects on crops and weeds, soils, insects and disease. In terms of crops, the main climatic variables that are important are temperature, solar radiation, water and atmospheric CO2 concentration. ... Plant growth and crop yields depend on temperature and temperature extremes.Plants, Animals, and Ecosystems. Most plants and animals live in areas with very specific climate conditions, such as temperature and rainfall patterns, that enable them to thrive. Any change in the climate of an area can affect the plants and animals living there, as well as the makeup of the entire ecosystem.Healthy ecosystems and rich biodiversity are fundamental to life on our planet. Climate change is affecting the habitats of several species, which must either adapt or migrate to areas with more favourable conditions. Even small changes in average temperatures can have a significant effect upon ecosystems.

Changing climate affects ecosystems in a variety of ways. For instance, warming may force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival. ... For instance, climate change may exacerbate the stress that land development places on fragile coastal areas

Plants are adapted to the 40 % lower CO2 concentration we have had the last 400.000 years. They will manage just fine.

Plants have no problems with changing CO2 levels. Even if some species cannot adjust others will. Evolution will take care of this. The problem is with human kind. Someplants that cannot adjust might be important food crops. Eco-systems have changed over billions of years. There were times when CO2 concentrations were much much higher. There were times when temperatures were much lower (and higher). Climate Change theatens societies, and carbfix, if at all, might have impacts that concern societies....
