Plants Are Absorbing More CO2 From the Atmosphere Without Using More Water

Trees, bushes, and other land-based plants are sucking up more carbon dioxide without a commensurate increase in water consumption, according to new research out of Australia that scientists claimed had major implications for modeling and preparing for climate change. Jungles near the equator, piney northern forests, and other flora are absorbing 17 percent more carbon dioxide than 30 years ago, resulting in land plants acting as “sinks” for around 30 percent of the carbon in the atmosphere, said the study published July 24 in the journal Nature Communications. The oceans absorb another 25 percent. It’s no surprise that plants would...

New Way of Transforming CO2 Is More Efficient Than What Plants Do

By tinkering with the process that plants use to breathe in carbon dioxide, a team of German scientists has just discovered a far more efficient way to get rid of it. Biochemists led by Tobias Erb at the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany, have developed a new, super-efficient method for living organisms to suck CO2 out of the atmosphere. Plants, algae, and other organisms turn CO2 into fuel. Erb and his colleagues reengineered this process, making it about 25 percent more energy efficient and potentially up to two or three times faster. The study appears in...

Can Chemists Turn Pollution into Gold?

We humans emitted 35.9 metric gigatons of carbon dioxide into the atmosphere in 2014, mostly from burning coal and natural gas in power plants, making fertilizer and cement, and other industrial processes. If chemists could capture carbon dioxide and turn it into chemical building blocks for other products, the way plants do, says Cornell University chemical engineer Lynden Archer, “carbon dioxide would not be a nuisance anymore, but a gift.” For years scientists have been trying to store carbon dioxide captured from exhaust flues at power plants and other emitters, mostly by injecting it deep underground. Without large subsidies, however,...

Climate change breakthrough: CO2 turned into stone in Iceland

Carbon dioxide has been pumped underground and turned rapidly into stone, demonstrating a radical new way to tackle climate change. The unique project promises a cheaper and more secure way of burying CO2 from fossil fuel burning underground, where it cannot warm the planet. Such carbon capture and storage (CCS) is thought to be essential to halting global warming, but existing projects store the CO2 as a gas and concerns about costs and potential leakage have halted some plans. The new research pumped CO2 into the volcanic rock under Iceland and sped up a natural process where the basalts react...
