Excessive groundwater pumping is draining pipes a lot of the world’s rivers

Excessive groundwater pumping is draining pipes a lot of the world’s...

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…
See what would occur if all the ice in the world melted over night

See what would occur if all the ice in the world...

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…
Here’s where Earth shops its carbon

Here’s where Earth shops its carbon

Human-driven carbon pollution is wreaking havoc on the global climate, from bleaching tropical corals to melting polar ice caps. But the amount of carbon in Earth’s oceans and atmosphere barely scratches the surface of the planet’s vast carbon reservoirs. Over the last decade, researchers affiliated with the international Deep Carbon Observatory have taken inventory of…
Cyclone Lorenzo struck Classification 5 further east than any other storm

Cyclone Lorenzo struck Classification 5 further east than any other storm

Hurricane Lorenzo broke records when it briefly strengthened to a Category 5 storm, with winds whipping near 260 kilometers per hour, as it spun over the eastern Atlantic Ocean on September 28. No other tropical cyclone that has formed in the Atlantic has reached such intensity that far northeast since record-keeping began in 1851. The…

NASA released this visualization of a black hole in September 2019. NASA's Goddard Space Flight Center/Jeremy Schnittman Everyone loves black holes. They're weird and mysterious and we all went nuts when we saw the first image of a black hole in April. NASA's black hole experts popped up on Reddit on Friday to field questions…
Earth might remain in its most popular five-year duration ever tape-recorded

Earth might remain in its most popular five-year duration ever tape-recorded

Mean surface temperature change during the North American summer in 2019 compared to 1981-2010. NASA/GISS We've just sweltered through the the hottest July ever recorded, complete with extreme heatwaves, and today a landmark report by a conglomerate of climate research organizations demonstrates the planet is warming like never before. The new assessment, commissioned by the United…

The future of sea level rise may be written into the walls of coastal Spanish caves. Mineral “bathtub rings” deposited inside the limestone Artà Caves on the Balearic island of Mallorca show how high seas rose during the Pliocene Epoch — a time when Earth was about as warm as it’s expected to get by…
Engineers Can Assist In Saving The Earth

Engineers Can Assist In Saving The Earth

More than two decades ago, the CEO of BP, one of the biggest oil and gas companies in the world – gave a speech to the 1997 graduating class at Stanford University. In the speech, John Browne acknowledged for the first time the link between the fossil fuel industry and global warming. Afterward, the American…
How ancient oceans of lava might have improved Earth’s oxygen levels

How ancient oceans of lava might have improved Earth’s oxygen levels

We may have ancient magma oceans to thank for Earth’s breathable air. Shortly after the planet’s formation about 4.5 billion years ago, the mantle somehow became much richer in oxygen than it was originally. That rock began leaking molecules like carbon dioxide and water into the oxygen-poor atmosphere — helping to jump-start conditions suitable for…
