Mathematics of Planet Earth 2013 (MPE 2013) has been an initiative of mathematical sciences organizations around the world designed to showcase the ways in which the mathematical sciences can be useful in tackling our world's problems. This initiative led to many events in 2013, including more than 10 long term programs at institutes around the world, more than 50 workshops, many invited speakers and special sessions at societal meetings, numerous public lectures, the development of educational materials, art exhibits, and an international prize competition to create innovative modules for display and use and which can be widely disseminated and exhibited. The problems facing our planet will persist, and so MPE2013 has been extended into the future, now called MPE. For more about this initiative, see http://mpe.dimacs.rutgers.edu/.
In the US, the efforts in MPE going forward are being run under the name Mathematics of Planet Earth 2013+ (MPE 2013+). MPE2013+, which is supported by the US National Science Foundation, aims to involve mathematical scientists in laying the groundwork for a long-term effort to sustain MPE activities beyond 2013.
