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.
NESTA Field Trips
Each year at the spring NSTA National Conference on Science Education, NESTA hosts an earth science related field trip that explores local geology and/or local places of interest related to the earth sciences. This all day field trip usually takes place the day before the NSTA conference begins. For details on the next field trip including itinerary and costs, check information about our current field trips closer to the date of the conference or contact a NESTA Executive Board Member.
