It can be hard to find good news about the future so here is a win for the environment. I remember when holes in the Ozone Layer were some of the biggest climate emergencies we were facing. Lets hope we do the same with carbon emmisions!
The Montreal Protocol, an international treaty to protect our ozone signed in 1987, has been a success, declared the U.N.-backed scientific panel in a report first released in October 2022 and formally presented on Monday at the American Meteorological Society meeting.
Despite a major setback in the 2010’s, the amount of ozone-depleting chemicals emitted worldwide has decreased since 2018. In sum, nearly 99% of those harmful compounds have been phased out since the 1980’s, according to a Monday press release. If all continues according to plan, the ozone layer is expected to recover to pre-1980 levels worldwide, including over the Antarctic, by 2066, the assessment says.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
