California's summer of 2021 has seen record-breaking wildfire outbreaks, surpassing 2020 by over 500 fire events by mid-July. Over the period of 2020 and 2021, California has also experienced its two largest wildfires ever , the Dixie and August Complex fires. Levels of Ground-level Ozone Pollution Can Increase in Summer.

Guest Post By Erin Boedicker , 2020-2021 Sustainability Leadership Fellow and Ph.D. When fuels are burned to create energy in a process called combustion, black carbon along with carbon monoxide and other compounds are created because there is not enough oxygen in the atmosphere for the reaction to go to completion.

When a firework explodes, it releases a combination of fine particulate matter (which includes heavy metals, as well as poisonous gases) into the atmosphere. Studies have also shown that fireworks can create a ‘burst’ of ozone formation, also harmful to human health. This can cause a rapid impact on the surrounding air quality.

They do this by analysing the electromagnetic absorption spectra of an exoplanet’s atmosphere as it transits its sun, seeking the presence of gases such as oxygen, methane, water vapour and ozone (a proxy for oxygen). Analogous to technosignatures, these are the signs of life on alien worlds, intelligent or otherwise.

Methane is a potent greenhouse gas that traps about 80 times as much heat as carbon dioxide, on average, over the first 20 years after it reaches the atmosphere and is responsible for approximately one third of the warming from greenhouse gases occurring today.
