Can We Suck Up Enough CO2 to Cool the Planet?


Klaus Lackner’s lab at Arizona State University looks as if an artificial Christmas tree exploded. Seemingly every surface is covered by white shreds of material, some small, some large, some slim, some thick. They look like plastic, but have the feel of stiff leather. And they are, according to Lackner, the head of the university’s Center for Negative Carbon Emissions, our best hope for avoiding catastrophic climate change.

Lackner’s resin strips absorb carbon dioxide when they’re dry and release it when they’re wet. In cooperation with the Dublin-based company Carbon Collect and his colleagues at Arizona State, he wants to build an artificial forest in the desert: 1,200 CO2-eating columns, each up to 30 feet tall, that could capture 100 tons of carbon dioxide per day — the equivalent of sucking up the emissions of about 8,000 cars. The white shreds will form the leaves of the “mechanical trees,” passively absorbing CO2 as the wind passes through them.

Climate change is making Texas hotter, threatening public health, water supply and the state’s infrastructure


Climate data also show that the state is experiencing extreme rainfall — especially in eastern Texas — bigger storm surges as seas rise along the Gulf Coast and more flooding from hurricanes strengthened by a warming ocean, the report says.

Those trends are expected to accelerate in the next 15 years, according to the report, which analyzes extreme weather risks for the state and was last updated in 2019.

Germany unveils first self-driving train


German rail operator Deutsche Bahn and industrial group Siemens on Monday unveiled the world's first automated, driverless train in the city of Hamburg, billing it as more punctual and energy efficient than traditional trains.

Four such trains will join the northern city's S-Bahn rapid urban rail network and start carrying passengers from December, using the existing rail infrastructure.
