Carbon Dioxide

Researchers in the UK have come up with a new formula for tackling smoldering "zombie fires", which can burn through carbon-rich organic matter underground and trigger flaming wildfires again once the danger appears to have passed.

Unfortunately concrete production is a major source of carbon dioxide in the atmosphere. Now engineers at Purdue University have developed a new cement recipe that can absorb CO2 twice as fast as usual, hopefully turning it into a useful carbon sink.

Tesla and SpaceX CEO Elon Musk has stumped up $100 million for a new XPrize competition that takes aim at the problem of carbon pollution, with hopes of unearthing technologies that can remove it from the atmosphere and ocean.

Comprehensive climate data has shown that globally, 2020 was the warmest year on record, tied with 2016. Worryingly, 2020’s record came in spite of a La Niña event, which has a cooling effect, while 2016’s record came off the back of a warming El Niño.

While you might think that dried almonds are one of the "safer" foods, they're actually prone to contamination by harmful bacteria. A simple new process could help keep that from happening, while also boosting their shelf life.

Algae plays an important role in removing carbon dioxide from the atmosphere, and a first-of-a-kind research expedition is set to highlight just how important that role might be by studying the density of dead algae at various depths.

A team from the University of Cambridge has produced a wireless sheet packed with photocatalysts that converts sunlight, water and carbon dioxide into clean fuels, with hopes of one day using the device as part of giant energy farms.

Researchers at the US Dept of Energy's Argonne National Laboratory have discovered a new catalyst that can convert carbon dioxide and water into ethanol with "very high energy efficiency, high selectivity for the desired final product and low cost."

A new study out of the University of Sheffield makes a case for a geoengineering technique known as enhanced rock weathering, which essentially involves supercharging soil’s ability to remove CO2 from the atmosphere by sprinkling it with rock dust.

Carbon dioxide is an all too common waste product of industry, belched into the air from smokestacks. Now, researchers have developed a new type of fluorinated membrane that can selectively filter CO2 out of flue gas at the point of release.

Scientists in Australia are claiming to have developed a new technique that converts waste carbon dioxide into simple chemical building blocks that they liken to Lego, which can then be turned into useful products such as synthetic fuels and plastics.

Current levels of carbon dioxide in the atmosphere are the highest they’ve been in a long time. According to a new study of fossil plant matter, CO2 concentrations haven’t been this high in at least 23 million years, and have never shot up this fast.
