Godzilla. Biblical. Historic. Muy malo. Even “new” (although it’s not; most people just haven’t heard of it).
This is the Saharan Air Layer – often given noms de guerre such as “African dust storm” – an approximately 5,000-mile-long, 2-mile-high plume of dust. It is a “phenomenon that develops every year off the coast of Africa,” writes Slate, “where powerful winds from thunderstorms over the Sahel can push the dust many thousands of feet up into the atmosphere.”

Finally, some positive news about climate change: Even small groves in your backyard or city park help fight the effects of rising temperatures, drought and greenhouse gases.
“Urban orchards and green spaces can contribute to a range of ecosystem services,” writes Weizmann Institute of Science postdoctoral researcher Rafat Qubaja in a soon-to-be-published paper.
Those “services” include storing carbon, reducing air pollution, regulating the urban microclimate, cooling and shading, retaining rainwater and soil moisture, recharging groundwater and more.

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.

In late 2020, a team of marine scientists investigating Australia’s Great Barrier Reef came across a remarkable sight: a “detached coral feature that rises from the seabed to a height of nearly one-third of a mile,” reported The New York Times. It is “the first large new element of Australia’s famous reef system to be identified in more than 120 years.”
Coral is, in many ways, our environmental canary in a coal mine. Sensitive to changes in acidity, temperature, currents, and the like, these animals are early warning systems of climate change and its damage. Until the new finding, it felt like news about coral ranged from “depressing” to “even more depressing.” For example, in spring 2020, scientists reported that over half of the Great Barrier Reef’s corals had died since 1995, largely due to climate change-induced mass bleaching.

Over the last 50,000 years, humans have caused the extinction of 10-20 percent of all avian species, a new study reveals.
This includes at least 469 known species of birds, though the actual figure is believed to be much higher.
The study was led by Prof. Shai Meiri of the School of Zoology and Steinhardt Museum of Natural History at Tel Aviv University, and Amir Fromm of the Weizmann Institute of Science.
Oct 23, 2021... When you find the time to walk on a trail through a forest, it can be breathtaking to look upwards to the top of a towering tree and feel so small by comparison. In fact, trees hold some of the most impressive records in the natural world with regard to their age and their height. And just like many natural and ecological marvels, a threat to highly valued trees creates a cause for concern as they are typically viewed as a unique mark of environmental pride.
