Is climate change a serious risk, as discussed in the book Collapse by Jared Diamond? Or is it just an environmental hoax, as suggested in Michael Crichton's novel, State of Fear?
Celebrate Earth Day by joining Dr. Bruce Wielicki from the Science Directorate, as he summarizes the science behind the concerns, risks, uncertainties and challenges associated with global climate change in a lecture at the Virginia Air & Space Center on April 21 at 7:30pm.
Wielicki is the senior scientist for Earth Science here at NASA Langley Research Center and has studied and lectured on climate science for more than 25 years. He received NASA's Science and Leadership medals, and is the Principal Investigator for CERES, a satellite mission to study Earth's radiation budget and climate.
