1. State of the Climate - NOTES This is a short presentation to establish the basics of what is happening to the climate before discussing what we can do about it (And now the GOOD news). This ppt does not try to establish the science of climate change. See ClimateScienceMar2010.ppt or other AIP ppts for that. This presentation was prepared for the Australian Institute of Physics Education Committee (Vic) by KB and is for the use of science teachers in talking with their students and with the general public. The source of most images and graphs is acknowledged in the notes pages. Glacier and snow photographs Keith Burrows.

2. “State of the Climate” What are the scientists telling us?

3. Many scientific organisations have produced reports in an attempt to get people to listen

30. Lagos — More than ten million people across West Africa are facing severe hunger and malnutrition because of drought, poor harvests and rising food prices Worsening conditions in the Sahel region of West Africa have seen malnutrition rates soar as families struggle to find enough food to eat Niger - the world's least developed country - more than seven million people, almost half the population, facing food insecurity; 3.3 million, approaching a quarter of the population, are severely food insecure. Another two million people in Chad, more than 600,000 in Mali and more than 300,000 in Mauritania are at risk. Sub-Saharan Africa

31. “There's no doubt that clearly the climate change is a major contributing factor,” said Dr Ghassem Asrar, director of the World Climate Research Program and the World Meteorological Organisation (WMO). Scientists are usually more comfortable with trends and prognostications than with cause and effect; most would never ascribe a single weather event to climate change. Which makes Asrar's declarations and similar ones from other experts all the more remarkable. The Age 21 August 2010 Is it climate change?
