Through its ...read more
If you've checked out parts 1 and 2 of this three-part series examining the new State of the Climate 2023 report, you already know that greenhouse gases have been continuing their relentless growth in the atmosphere, and that 2023 shattered previous global heating records. Here in Part 3 of the series, I look at some of the other impacts, starting with one that took me surprise: In addition to being the warmest year, 2023 was also the least cloudy ever observed globally in records dating back fo ...read more
We've known for awhile that 2023 was by far the warmest year on record, triggering widespread alarm among climate scientists. Now, a newly released climate report reveals other disturbing trends.No aspect of Earth's climatic life support system was spared from humankind's impact last year, according to the State of the Climate 2023 report, led by scientists from the National Oceanic and Atmospheric Administration and published by the Bulletin of the American Meteorological Society. Driving it a ...read more
In Part 1 of this three-part series focusing on a new report about climate change in 2023, I described the relentless rise of greenhouse gases in the atmosphere. Rather than showing signs of leveling off — which must happen soon if we are to avoid even more disruptive climate changes than we've already seen — they're accumulating at an increasing rate. In fact, 2023 saw the fourth highest rise of atmospheric CO2 on record.As I pointed out in Part 1, no aspect of Earth's climatic life support ...read more
Brain-computer interfaces are a groundbreaking technology that can help paralyzed people regain functions they’ve lost, like moving a hand. These devices record signals from the brain and decipher the user’s intended action, bypassing damaged or degraded nerves that would normally transmit those brain signals to control muscles.Since 2006, demonstrations of brain-computer interfaces in humans have primarily focused on restoring arm and hand movements by enabling people to control computer cu ...read more
