Scientists Demand 'Paradigm Shift' After Study Shows 'Frightening' Decline of Insects and Spiders
"A decline on that scale over a period of just 10 years came as a complete surprise to us," said one researcher, "but fits the picture presented in a growing number of studies."

The World Solved the Ozone Problem. It Can Solve Climate Change.
Nearly 50 years ago, three chemists named Mario Molina, Sherwood Rowland and Paul Crutzen found evidence that chlorofluorocarbons, chemicals known as CFCs and released from aerosol sprays, were weakening the ozone layer that functions as the earth’s natural sunscreen protecting humans, animals and plants from harmful radiation.

Don't discount carbon capture just yet, study says. It could go underwater.
Humanity has some quick approaching deadlines to meet in the coming years if we want to stave off the worst effects of climate change, and scientists say one solution, carbon capture and storage (CCS), is ready to start today — but it’s not an option many people aren’t thrilled about.

Life could have emerged from lakes with high phosphorus
Life as we know it requires phosphorus. It’s one of the six main chemical elements of life, it forms the backbone of DNA and RNA molecules, acts as the main currency for energy in all cells and anchors the lipids that separate cells from their surrounding environment. But how did a lifeless environment on the early Earth supply this key ingredient?

The planet has a problem with buildings: Here's how smart ideas, tech and design can change that
Whether it’s a creaky old house or a brand new, state of the art office block, the buildings we live and work in have a big impact on the environment. The challenge to reduce this footprint is sizable. According to a recent report from the Global Alliance for Buildings and Construction, International Energy Agency and the UN Environment Programme, building construction and operations were, globally, responsible for 36% of final energy use in 2018.

CO2 sucked out of the atmosphere can be reused for new chemical processes
Global warming is the biggest challenge we have ever faced. Since the first industrial revolution, the amount of carbon dioxide (CO2) — a powerful greenhouse gas — in the atmosphere has increased by almost 50%, which is causing a steep rise in global temperature. Controlling its increase and keeping temperature rise below 1.5 degrees is necessary to avoid the most catastrophic effects of climate change. However, that likely requires stopping new emissions immediately and reducing the excess CO2 that is already in the atmosphere.

There Are So Many Ways Of Capturing Carbon Dioxide: We Must Start Using Them Now
A new study highlights the need for a crash program to develop Carbon Capture and Storage (CCS) technology and to agree on targets for each country, if we are to have any chance of avoiding the worst effects of the climate emergency, which are likely to occur much sooner than expected.

Carbon capture 'moonshot' moves closer, as billions of dollars pour in
As the world dices with the climate emergency, businesses and governments are starting to push funding towards technology that aims to trap planet-heating gases rather than let them saturate the atmosphere. Carbon capture is a controversial idea, attacked as a costly distraction from stopping emissions occurring in the first place.

Breakthrough in Turning Straw Into Valuable Biochemicals
Many have dreamed of being able to turn straw into gold like the fabled Rumpelstiltskin. While this may not be possible in the literal sense, scientists are using sunlight to turn straw into something more valuable.

A Bill Gates Venture Aims To Spray Dust Into The Atmosphere To Block The Sun. What Could Go Wrong?
Microsoft’s MSFT +0.2% billionaire founder Bill Gates is financially backing the development of sun-dimming technology that would potentially reflect sunlight out of Earth’s atmosphere, triggering a global cooling effect. The Stratospheric Controlled Perturbation Experiment (SCoPEx), launched by Harvard University scientists, aims to examine this solution by spraying non-toxic calcium carbonate (CaCO3) dust into the atmosphere — a sun-reflecting aerosol that may offset the effects of global warming.

Researchers report possible solutions for hard-to-recycle plastics
Millions of tons of plastic end up in landfills every year. It's a big societal problem and an even larger environmental threat. In the United States, less than 9% of plastic waste is recycled. Instead, more than 75% of plastics waste ends up in landfills and up to 16% is burned, a process that releases toxic gases into the atmosphere.

How This CO2 ‘Vacuum Cleaner’ Is Fighting Climate Change
While much of the world took a pause in 2020, climate change did not. And as countries figure out how to reach the goals set in the Paris Agreement, it’s clear that dramatic action—and outside-the-box solutions—are needed to cut emissions. Swiss company Climeworks is working to provide some of those to help reverse climate change with its direct-air-capture technology.

Neal Stephenson on his new geoengineering climate change thriller and coining the term 'metaverse'
Author Neal Stephenson shot to fame almost 30 years ago with the science-fiction novel “Snow Crash,” which envisioned a future dominated by mega-corporations and organized crime, competing for dominance in both the real world and the “metaverse,” a computer-generated world accessible through virtual reality headsets.
