Over the last year, US greenhouse emissions increased by 6.2 percent compared to 2020 levels, according to a new report from the Rhodium Group. The jump puts the country further behind meeting the reduction targets put forward by the Paris climate agreement. Under the deal, the US has pledged to reduce its greenhouse emissions between 50 percent and 52 percent below 2005 levels by 2030. As of last year, they were 17.4 percent below that benchmark. That's a step back from the 22.2 percent reduction the country had achieved the year prior.
Serio said his greenhouse has room for 1,400 lettuce plants -- he grows them in seven-week cycles, 200 plants at a time from seeds to harvest -- in hydroponic tubes.

Have blue-collar workers fallen for a Republican bait-and-switch? On The Gist, journalist Steven Greenhouse sets aside globalization and turns to the domestic forces suppressing wages and hammering workers: Republican-backed anti-union laws, a feeble response from Democrats, and cultural amnesia around the labor movement's achievements. Greenhouse is working on a follow-up to his 2008 book, The Big Squeeze: Tough Times for the American Worker.
If we hope to someday inhabit other planets, astronauts will need more sources of nourishment than the packets of freeze-dried space food they can take with them. It's not just the nutritional value of fresh produce that has NASA interested in growing greens -- researchers think that astronauts would also get a psychological boost from farming. To that end, NASA collaborated with researchers at the University of Arizona to design an inflatable greenhouse that can be deployed in space and offer astronauts a sustainable bounty of fresh vegetables. The greenhouse prototype was built as a "bioregenerative life support system" -- meaning it recycles air, waste, and water. As astronauts breathe out, they release carbon dioxide, which the plants use to generate oxygen through photosynthesis.
A technicolour greenhouse has emerged in the middle of central Tokyo. SEE ALSO: What happens when you watch'Game of Thrones' on LSD The aptly-named Digital Vegetables, complete with psychedelic lights and a symphony of plants, is part of a design-based event that's happening in Tokyo. I mean, just look at it. Look at it, just casually lying there being amazing. The greenhouse has seven types of vegetables planted inside, with each vegetable triggering a different sound when touched.
