Earth Currently Experienced 5 Huge Mass Terminations, Now Human Beings Are...

Environmental degradation by human activity is one of the main causes of biodiversity loss. D.Bressan In Earth's long history estimated 99% of all species ever living here went extinct. Extinction is part of life's history and extinction of single species happens all the time. Over time lost species are eventually replaced as natural selection acts…

In science, transparency is typically considered a virtue. But a rule proposed by the U.S. Environmental Protection Agency, billed as a means to keep environmental regulations rooted in reproducible science, is getting pushback from the scientific community. The proposal, titled “Strengthening Transparency in Regulatory Science,” would require studies that factor into EPA rule-making to be…

Humankind’s collective thirst is slowly desiccating landscapes worldwide, a study of groundwater finds. Water stored in aquifers underground makes up the vast majority of accessible freshwater on Earth. Its abundance has fueled forays into drier locales, such as California’s Central Valley, enabling a boom in crop production (SN: 7/23/19). And overall, about 70 percent of…

Following is a transcript of the video. Ninety-nine percent of all freshwater ice on Earth is sitting on top of Greenland and Antarctica, and each year, a little more of it melts into the ocean. Normally, it would take hundreds to thousands of years for it all to melt away. But what if something happened…

The glory shimmers near the center of the image. Alexander Gerst/ESA If you're lucky, you may have seen one during your time on Earth. A glory is a shimmering optical phenomenon that forms when water droplets scatter light. It's ethereal, like a rainbow halo that shifts from red on the outside to blue on the…
Dire warning: Earth may have crossed climate ‘tipping points’

Dire warning: Earth may have crossed climate ‘tipping points’

Smoke, from intense fires, rises over the Amazon rainforest in August. Joao Laet/Getty A handful of climate scientists have warned Earth may have already crossed critical climate "tipping points," potentially resulting in irreversible changes to the environment. As greenhouse gas concentrations in Earth's atmosphere continue to rise, the authors of a new commentary piece, published in…
