A NASA study has analyzed data gathered by the OCO-2 satellite and pinpointed the cause of an unprecedented spike in atmospheric CO2 in 2015 and 2016: the El Nino weather effect caused certain tropical regions to release far more CO2 than they normally would.

In the history of life on Earth, there have been five mass extinction events. Now, an MIT professor has analyzed the changes that took place in the carbon cycle leading up to these events and found that the end of this century could mark the tipping point for a sixth mass extinction event.

Much study has focused on the effects these rising carbon dioxide levels could have on weather patterns and global temperatures, but could elevated atmospheric CO2 levels negatively affect the nutritional value of the food we grow?

We might be on track to topple a climate record that’s held strong for about 56 million years. A new study has found evidence that intense volcanic eruptions were to blame for the Palaeocene-Eocene Thermal Maximum (PETM), pumping mind-boggling amounts of carbon into the atmosphere and oceans.

Scientists working in Antarctica have drilled the oldest ice core ever found. Dating back an estimated 2.7 million years, this ice sample is more than 1.5 million years older than any other previously recovered and offers a rich insight into the climate of the planet millions of years ago.

Researchers at Rice University have developed a new material that could be used to capture carbon dioxide from the atmosphere. Made from hexagonal-boron nitride (h-BN) and polyvinyl alcohol (PVA), the foam can soak up more than three times its own weight in CO2, and is reusable.

Some of the excess carbon dioxide in the air is absorbed by “carbon sinks” like forests and oceans, which helps slow down, but not stop, the greenhouse effect. Unfortunately, a new study has found that oceans are gradually becoming less effective carbon sinks, thanks to rising global temperatures.

Ice core records show that temperatures suddenly soared several times during the last glacial period. A new study has found evidence that these sudden spikes may be triggered by a slow rise in atmospheric CO2 levels, up to a “tipping point” that abruptly affects ocean circulation and global climate.

To reduce the severity of climate change, it’s not enough to just curb the rise in emissions –technologies that actively pull more CO2 out of the atmosphere will also be vital. To that end, a new CO2-filtering plant has just opened up near Zurich.

A new water purification technology developed by researchers at Princeton University doesn't require filters, instead relying on the injection of CO2 gas to change the water's chemistry and separate waste particles based on their electrical charge.
