Mar 18, 2021... REHOVOT, ISRAEL—March 18, 2021—It’s not just how hot the fires burn – it’s also where they burn that matters. During the recent extreme fire season in Australia, which began in 2019 and burned into 2020, millions of tons of smoke particles were released into the atmosphere. Most of those particles followed a typical pattern and settled to the ground after a day or week; however, the particles created in fires burning in one area of the country managed to blanket the entire Southern Hemisphere for months. When studying particle-laden haze, two researchers at the Weizmann Institute of Science noticed puzzling spikes in a certain measurement, and tracked the elevated levels to the fires in that area. Next, as reported in Science, the Israeli scientists uncovered the “perfect storm” of circumstances that swept the particles emitted from those fires into the upper atmosphere and spread them over the entire Southern Hemisphere.

The 2019–20 wildfires in Australia injected huge amounts of smoke into the stratosphere, which has led to record aerosol levels over the southern hemisphere.
Ilan Koren at the Weizmann Institute of Science in Israel and Eitan Hirsch at the Israel Institute for Biological Research analysed satellite data collected between 1981 and 2020 to look at what effect the devastating bushfire season in Australia had on aerosol concentrations in the stratosphere.

While Earth Day is 51 years old this year, the Earth is 4.54 billion years old – “plus or minus about 50 million years,” says the National Geographic Society. And yet in less than 200 years, the blink of an eye, humankind has thrown a wrench into our small planet’s carefully tuned systems.
Since the Industrial Age, our remarkable advances have had a flip side: chemicals, pharmaceuticals, fossil fuels, and the like have fouled our water, land, and climate. We have increased Earth’s temperature, causing mass extinctions, stronger storms, devastating wildfires, flooding, and food shortages – consequences that will only increase. And while we can all take personal steps, there is ultimately one hope for mitigating human impacts on the planet: science.

What’s one of the first things you do when you get to the ocean? It’s probably to take a deep breath, inhaling the instantly familiar smell that inspires calm, evokes memories, and lets you know exactly where you are.
Every other breath you take is provided by the ocean, which supplies half of the entire planet’s oxygen. It is Earth’s life support system: it regulates our climate, feeds us and innumerable other species, and its health and well-being are critical to maintaining our own – yet we do not behave as though it is.
