Carbon Dioxide

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.

Scientists at Newcastle University have happened upon a particularly promising example if a carbon capture technology, developing a low-cost membrane that assembles one of its own key components as it absorbs CO2.

Scientists at Purdue University are putting forward another interesting proposition in the realm of home automation, developing a cheap sensor that can detect when a person enters a room via carbon dioxide levels in the air.

Scientists have developed a biohybrid reactor that can take carbon dioxide and turn it into versatile organic compounds, using bacteria and a forest of nanowires to make these conversions with what they claim is record efficiency.

One argued silver lining of rising atmospheric carbon dioxide levels is that plants will be better off. But a new study has found that the more extreme heat and drought brought on by climate change would cancel out most of the benefits for trees.

The Statement on the State of the Global Climate in 2019 report confirms that last year was another record-breaker, continuing a worrying trend that indicates we’re drifting further off-track from meeting the targets of the 2015 Paris Agreement.
