During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well.
Membership Meeting
Our annual Membership Meeting takes place on the Earth Science Resource Day at the spring NSTA National Conference on Science Education. Updates from NESTA Executive Board Members are given and new Executive Board Members are introduced. This meeting provides the latest news about earth science education, and is an opportunity for members to make recommendations to the NESTA leadership. If you plan on attending the NSTA annual conference, plan on attending the NESTA membership meeting to meet your NESTA leadership team.
