What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

Experts say that the devastating earthquake in Myanmar on Friday was likely the strongest to hit the country in decades, with disaster modeling suggesting thousands could be dead.

Myanmar's ruling junta said on Saturday morning that the number killed had passed 1,000, with more than 2,000 injured.

However, the USGS analysis said there was a 35% chance that possible fatalities could be in the range of 10,000-100,000 people.

The USGS offered a similar likelihood that the financial damage could total tens of thousands of millions of dollars, warning that it might exceed the GDP of Myanmar.

China's glacier area has shrunk by 26% since 1960 due to rapid global warming, with 7,000 small glaciers disappearing completely and glacial retreat intensifying in recent years, official data released in March showed.

...

As the important water towers continue to shrink, less availability of freshwater is expected to contribute to greater competition for water resources, environmental groups have warned. Glacier retreat also poses new disaster risks.

China's glaciers are located mainly in the west and north of the country, in the regions of Tibet and Xinjiang, and the provinces of Sichuan, Yunnan, Gansu and Qinghai.

Data published on March 21 on the website of the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences, showed that China's total glacier area was around 46,000 square kilometres, with around 69,000 glaciers in 2020.

This compares to around 59,000 square kilometres and around 46,000 glaciers in China between 1960 and 1980, the study showed.

...

The Tibetan plateau is known as the world's Third Pole for the amount of ice long locked in the high-altitude wilderness.

...

The dramatic ice loss, from the Arctic to the Alps, from South America to the Tibetan Plateau, is expected to accelerate as climate change, caused by the burning of fossil fuels, pushes global temperatures higher.

This would likely exacerbate economic, environmental and social problems across the world as sea levels rise and these key water sources dwindle, [a UNESCO report says].

MIT aerospace engineers have found that greenhouse gas emissions are changing the environment of near-Earth space in ways that, over time, will reduce the number of satellites that can sustainably operate there.

In a study appearing today in Nature Sustainability, the researchers report that carbon dioxide and other greenhouse gases can cause the upper atmosphere to shrink. An atmospheric layer of special interest is the thermosphere, where the International Space Station and most satellites orbit today. When the thermosphere contracts, the decreasing density reduces atmospheric drag — a force that pulls old satellites and other debris down to altitudes where they will encounter air molecules and burn up.

Less drag therefore means extended lifetimes for space junk, which will litter sought-after regions for decades and increase the potential for collisions in orbit.

[...]

Their predictions forecast out to the year 2100, but the team says that certain shells in the atmosphere today are already crowding up with satellites, particularly from recent “megaconstellations” such as SpaceX’s Starlink, which comprises fleets of thousands of small internet satellites.

“The megaconstellation is a new trend, and we’re showing that because of climate change, we’re going to have a reduced capacity in orbit,” Linares says. “And in local regions, we’re close to approaching this capacity value today.”

“We rely on the atmosphere to clean up our debris. If the atmosphere is changing, then the debris environment will change too,” Parker adds. “We show the long-term outlook on orbital debris is critically dependent on curbing our greenhouse gas emissions.”
