I've seen the table of contents (as well as my own chapter obv!) and it's very impressive. The book is well-organized, comprehensive, and includes over 50 top experts. This is going to be a fantastic one-stop resource for the classroom and beyond. theguardian.com/books/2022/m…

#ReadyToGOES? You know it. @NOAA's GOES-T separated from its @ULALaunch Centaur upper stage after a successful launch yesterday, March 1. The satellite is on its way to helping provide more accurate weather forecasts and data about our changing planet. nasa.gov/goes

Happy 23rd birthday to GDAL ! From the first commit on 1998-10-17 from a small rural town outside of Ottawa Canada, to almost every geospatial software installation on the planet (and satellites and other planets!) in 22 years. The ultimate example of sharing & community. #foss4g

Thank you for sharing this.
So, we’ve reached 34 deaths per day from COVID. It’s a shocking number that really gets swamped over by all the other numbers. I’m going to describe the usual dying process in the ICU from this disease. I’m wearing my clinical hat, be warned.
