I don’t know how many of you have been able to escape the unbelievable heat wave happening around the globe. This summer my family has been suffering from the heat in both San Diego and Sweden. Noticing that out of the blue both my husband and son began coughing a lot, I did a little research and found something interesting.
During all these heat waves, when the ground gets very dry, plants tend to start protecting themselves to conserve water. That’s good for the plant but bad news for us. Plants are natural air purifiers for us humans since they absorb ozone and many other pollutants.
This is a huge problem for humans because three key ingredients — sunlight, hot air and pollution — create ground-level ozone, also known as smog, which is poor air quality. The research suggests that the increased ozone in the air can make people sick, and that they could even die.
Scientists say these “new” weather patterns with high, persistent heat and high humidity, which we’ve been experiencing here in San Diego and in Sweden, is a direct result of global warming. So, yes, our planet is warming up and slowly killing us as a consequence of the way we are treating it.
