Similar negative effects occur with worsening air
pollution — higher levels of ground - level
ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding —
as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).
While planting trees for bioenergy would no doubt lead to an uptick in
ozone pollution, it should be noted that burning fossil fuels — coal, oil, and gas — is generally seen
as a larger and graver contributor to air
pollution than tree plantations.
