Soliman said the finding that atrial fibrillation was associated only with NSTEMI heart attacks suggests that factors contributing to partial blockage of the coronary arteries or increased oxygen demand, such as sudden increase in heart rate, are more likely to explain the association between a-fib and heart attack than those factors linked to total blockage caused by the migration of a blood clot to a coronary artery from the site of its formation.

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).
