leonardodicaprio.org A century ago there were 100,000 Tigers in the wild, today there are as few as 3,200. Join our global campaign with World Wildlife Fund to protect these majestic creatures from extinction. “If we don’t take action now, one of the most iconic animals on our planet could be gone in just a few decades. By saving tigers, we can also protect some of our last remaining ancient forests and improve the lives of indigenous communities." - Leonardo leonardodicaprio.org
Environmental Visualization Laboratory - Coastal Upwelling Seen in Ocean Temperature Data The phenomenon of wind-driven upwelling occurs when high coastal winds blow over the ocean surface, pushing warm surface waters offshore and allowing cooler, more nutrient rich water from below to rise up to the surface. This process creates a signature in sea surface temperature (SST) data where cooler water can be seen surrounded by warmer water. Such upwelling zones are visible in this SST data acquired by the NOAA GOES and POES satellites on March 9, 2011. Notice the areas of cooler water off the west coast of Central America, where wind blowing through mountain valleys creates upwelling. Also, the west coast of South America shows much cooler water.

Climate Shifts

The University of Queensland has opened a free on-line course (1-2 year University level – http://bit.ly/JEnRkV ) on Tropical Coastal Ecosystems and Global Change as part of the edX partnership with Harvard and MIT. This exciting course will introduce the major tropical coastal ecosystems (principally coral reefs, mangroves, sea grass meadows) and will explore the problems and solutions that these critical systems face. The lecturers include Professors Hugh Possingham, Sophie Dove, Catherine Lovelock, Stuart Phinn and myself, with contributions from Drs Dorothea Bender, Ruth Reef, and Chris Roelfsema. The course starts on April 28. To find out more and register, go to http://bit.ly/JEnRkV
