The risks of harvest failures in multiple global breadbaskets have been underestimated, according to a study Tuesday that researchers said should be a "wake up call" about the threat climate change poses to our food systems.. Kornhuber said the study should be a "a wake up call in terms of our uncertainties" of the impacts of climate change on the food sector, with more frequent and intense weather extremes and increasingly complicated combinations of extremes.
Humanity's failure to draw down planet-heating carbon dioxide emissions -- 41 billion tonnes in 2022 -- has thrust once-marginal options for capping or reducing CO2 in the atmosphere to centre stage in climate policy and investment.. Unlike CCS, which by itself only prevents additional carbon dioxide from entering the atmosphere, DAC extracts CO2 molecules already there.Â

In a laboratory tucked away on a sprawling university campus in Rio de Janeiro, Brazilian molecular biologist Rodrigo Moura Neto is running tests on a seemingly ordinary plant with a potent secret.. "It was wonderful to find a plant (with CBD but) without THC, because you avoid all the mess around psychotropic substances," says Moura Neto, who has spent the better part of five decades researching in this small lab at Rio de Janeiro Federal University.
