A Joint Initiative of the North American Mathematical Institutions: Climate Change, Sustainability and the Mathematical Sciences2010 Joint Mathematics Meeting The 2010 Joint Mathematics Meeting was held January 13 - 16, 2010 in San Francisco. Nearly 6,000 people attended the meeting in 2009, and 2010 was even bigger. During 2010's Joint Meeting, an event representing a research initiative among North American mathematical institutions focused on climate change and sustainability. The controversy over the private e-mails that were hacked at a British university last month sparked the question that some scientists may have overstated their case or not reported the numbers correctly. It is more important than ever that the mathematicians take a lead role in collecting and properly interpreting the data.
Math Institutes Open House reception, Wednesday, January 13, 2010 from 5:30 p.m. to 8:00 p.m.
Schedule for the Open House
Images for climate change/sustainability stories CRM Workshop on Balance, boundaries and mixing in the climate problem, September or October 2011 to be organized by P. Bartello (McGill), S. Smith (Courant Institute), D. Straub (McGill) Captions: Videos (Courtesy of P. Bartello) 
Mixing of a passive tracer (e.g. dye or smoke) by a field of vortices on a hypothetical planet that is not rotating. The initial tracer field varied smoothly from red at the top to blue at the bottom (as in the colour bar at right). 
As above, but on a planet with very rapid rotation, such as Jupiter. Note that the effect of rotation is to increase the mixing in the east-west direction, but to decrease it in the north-south direction.

A numerical simulation of large-scale slowly-varying vortices that have spontaneously given rise to very intense small-scale activity (slightly above the centre of the frame). The latter is thought to reduce meteorological predictability and may lead to localised extreme events.

A field of interacting vortices in two-dimensional flow that is running down under the influence of viscosity (friction). Two-dimensional flow is used as a first approximation for atmospheric and oceanic vortices whose height is only of the order of 10 km, but whose width can be hundreds to thousands of kilometres.

Kiladis Caption: A longitude/time (increasing downward) plot of north/south averaged precipitation (as determined from cloud top temperature) around the equator in June 2002. The Madden-Julian Oscillation (MJO) wave is clearly seen starting around June 2nd near 55 degrees East (the western Indian Ocean), traveling eastward until it ends in the central Pacific Ocean about three weeks later. Embedded westward moving features hint at the multiple scales which are active in the MJO.
