The Deep Ocean Might Store Way Less Carbon Than We Hoped

The oceans are one of our planet’s most important carbon sinks, with currently around 39,000 gigatons of carbon dioxide locked away – that’s around 50 times more than what’s circulating in the atmosphere right now.   However, we can’t rely on this carbon capture and storage to solve our climate crisis problem, because we’re producing too… Continue reading The Deep Ocean Might Store Way Less Carbon Than We Hoped

Climate damage caused by growing space tourism needs urgent mitigation

Credit: CC0 Public Domain Published today in the journal Earth’s Future, researchers from UCL, the University of Cambridge and Massachusetts Institute of Technology (MIT) used a 3D model to explore the impact of rocket launches and re-entry in 2019, and the impact of projected space tourism scenarios based on the recent billionaire space race. The… Continue reading Climate damage caused by growing space tourism needs urgent mitigation

What is causing record floods and heatwaves in China?

Parts of southern China have been hit by record floods. Record floods in southern China this month displaced more than half a million people, while searing heat buckled roads in other parts of the country. Authorities have issued extreme weather warnings in multiple regions, while experts warned that these phenomena were more evidence of the… Continue reading What is causing record floods and heatwaves in China?

Oceans saved us, now we can return the favor

On current trends, pollution and overfishing could see as much plastic in the oceans as fish by mid-century. Humanity must heal oceans made sick by climate change, pollution and overfishing in order to rescue marine life and save ourselves, experts warned ahead of a major UN conference opening Monday in Lisbon. By absorbing—decade after decade—a… Continue reading Oceans saved us, now we can return the favor

Investigating the dynamics that reshape permafrost environments

Arsenic in private well water contributes to low birth weight even at low levels

Credit: Unsplash/CC0 Public Domain In the largest epidemiologic study of arsenic and birth outcomes to date, researchers from the University of Illinois Chicago and collaborating institutions estimated arsenic levels in U.S. private well water sources by county and compared estimates to documented birth outcomes. They found an association between estimated groundwater arsenic concentration and risk… Continue reading Arsenic in private well water contributes to low birth weight even at low levels

Drought hits Italy’s hydroelectric plants

The Po River is suffering its worst drought for 70 years. . Hydroelectric power in Italy has plunged this year thanks to a drought that has also sparked water restrictions and fears for agriculture, industry sources said Friday. Hydropower facilities, mostly located in the mountains in the country’s north, provide almost one fifth of Italy’s energy… Continue reading Drought hits Italy’s hydroelectric plants

Scientists offer solutions for China’s risky tap water

Credit: Pixabay/CC0 Public Domain High concentrations of disinfection byproducts in tap water are a possible culprit in adverse health outcomes. A recent study by Prof. Yu Wenzheng’s team from the Research Center for Eco-Environmental Science of the Chinese Academy of Sciences highlighted this risk and suggested sustainable solutions such as ozone biofiltration and nanofiltration to… Continue reading Scientists offer solutions for China’s risky tap water
