Taking the temperature of the global ocean is the topic of a free public lecture at Charles Sturt University (CSU) in Albury-Wodonga, Orange and Wagga Wagga by Distinguished Professor Tony Haymet from the University of California, San Diego (UCSD). From 2006 to 2012, the Australian scientist led the Scripps Institution of Oceanography at UCSD, a 110 year old geoscience research organisation focussing on the solid earth, oceans and atmosphere, and marine biology.  In his talks, Professor Haymet will track the factors that influenced the UCSD university and hospital campus community of 45 000 to change the way they generate energy. He will discuss how an understanding of how heat moves around the planet, developed through measuring ocean temperatures, can have impacts locally, nationally and globally. Professor Haymet is Director and Vice-Chancellor Emeritus at Scripps, and formerly Chief of Marine and Atmospheric Research at CSIRO in Australia. The lectures are part of CSU's 2014 Explorations Series which aims to encourage debate about the big issues facing society. The lectures are free and the public is welcome to attend.
