Carbon Dioxide

The last chapter in a trio of reports from the UN's top climate scientists has landed, with the authors noting some reasons for optimism, mounting an argument that the window is still open for meaningful action to limit warming to around 1.5 °C.

If mosquitoes seem to love you but ignore the person sitting next to you, the color of your clothes might be to blame. New experiments reveal that certain colors attract hungry mosquitoes, which could be used to design new traps or repellents.

"Artificial leaf" systems could play a key role in the fight against climate change, and a team of engineers has just picked up the pace with a solution that captures carbon dioxide at 100 times the rate of current technologies.

A new method quickly converts carbon dioxide into solid carbon, which can be stored indefinitely or turned into useful materials. The technology works by bubbling CO2 up through a tube of liquid metal, and could be used at the source of emissions.

A new study by the Planetary Science Institute and UCLA confirms that there are areas in the lunar south polar region where frozen carbon dioxide could exist, raising hopes that there could be significant resources to support future Moon missions.

A new initiative from the US Department of Energy makes carbon capture and storage technologies a key pillar in its plan to tackle climate change, aiming to drive down the cost and foster innovations that allow for storage on a mass scale by 2050.

Concrete is the most widely used building material in the world, but it comes at a huge environmental cost. Engineers in Japan have developed a new technique to make concrete by recycling waste concrete and combining it with captured carbon dioxide.

A company at the cutting edge of carbon capture technology has outlined its vision to use Australia's vast, open spaces and abundant sunlight to power millions of modular systems that would collect millions of tons of CO2 each year.

Carbon dioxide in the atmosphere attracts most of the attention in environmental concerns, but much of that ends up in oceans, making them more acidic. Now scientists have created nanojars that can easily capture this and other pollutants from water.

Climate change can feel inevitable, but we’ve stepped up to the challenge before. New modeling shows how bad things would be if CFCs hadn’t been banned decades ago – depleted ozone would've increased UV exposure and stopped plants capturing carbon.

According to a new report issued by the United Nations' Intergovernmental Panel on Climate Change (IPCC), human-caused climate change will have dire consequences over the next 20 years.

Carbon dioxide may finally get its chance to become a solution in the climate crisis. Italy's Energy Dome says its CO2 batteries will store energy at less than half the cost of lithium "big batteries," while also being very responsive to load demand.
