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.
-
The lockdown orders implemented around the globe to control the spread of the novel coronavirus have led to a dramatic dip in some airborne pollutants, and a new study has revealed that carbon dioxide emissions have followed a similar trend.
-
The wheels we humans have set in motion concerning carbon dioxide emissions and climate change are going to take some stopping, and the latest data from Hawaii's Mauna Loa Observatory are another clear indicator of this.

Photosynthesis is one of nature’s most useful chemical reactions, so scientists often try to mimic it. Researchers have now developed a new way to make hybrid synthetic-living cells that can use photosynthesis to clear carbon dioxide from the air.
