2. The air could be thick with pollution, worsening lung conditions and respiratory diseases

By 2050, the number of deaths caused by air pollution — which includes tiny particles found in smoke and haze, ground-level ozone typically emitted by cars, and toxic components in household products and building materials — will soar, killing more than 6 million people every year, according to a recent report from the Organisation for Economic Co-operation and Development (OECD).
Why? Because in addition to dirtier skies, warmer weather will speed up the chemical reactions that produce many pollutants.
One of those toxins is ground-level ozone, a chemical that irritates the delicate tissue lining the lungs and causes coughing, feelings of burning, wheezing, and shortness of breath when inhaled. Ozone often worsens respiratory conditions like asthma and emphysema.
In India, where the problem is especially bad, the OECD estimates that about 130 out of every 1 million people will die prematurely from exposure to ozone.
