5 February 2016, The Guardian, After climate cuts at CSIRO, who should we ask about global warming impacts on Australia? Netflix? Dr Penny Whetton had spent 25 years working on climate change modelling for Australia’s premier science agency, but in 2014 it was time to go. “I could see the writing on the wall,” says Whetton, who put up her hand to take a redundancy package in October 2014. This week, she has heard of the anger and sadness among her former CSIRO colleagues at the news that climate change research is being targeted for cutbacks and redundancies. Whetton still holds an Honorary Research Fellow position at the agency, where she had worked as a senior principal research scientist and one of the key people leading the CSIRO’s climate modelling work. She is one of a very small handful of Australian scientists to have been a lead author on three consecutive Intergovernmental Panel on Climate Change reports. Her central role has been to use climate models to work out the implications for climate change on Australia. Whetton had also been a leader of the project to deliver the latest climate change projections across Australia, released last year. In short, Whetton has intimate knowledge of what Australia’s climate modelling expertise is being used for. This week’s announcement by CSIRO executive director Larry Marshall has angered many in the country’s climate science community, who have been queuing up to criticise the moves. But beyond the implications of the announcement, there has also been much bemusement about Marshall’s statements and his apparent simplistic understanding of aspects of climate science. If Whetton saw the writing on the wall in October 2014 then surely everyone else should have been able to see the letters scrawled metres high when Marshall was appointed that same month.

25 January 2016, The Guardian. Sea level rise from ocean warming underestimated, scientists say. Thermal expansion of the oceans as they warm is likely to be twice as large as previously thought, according to German researchers. The amount of sea level rise that comes from the oceans warming and expanding has been underestimated, and could be about twice as much as previously calculated, German researchers have said. The findings in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal, suggest that increasingly severe storm surges could be anticipated as a result. Sea level can mount due to two factors – melting ice and the thermal expansion of water as it warms. Until now, researchers have believed the oceans rose between 0.7 to 1mm per year due to thermal expansion. But a fresh look at the latest satellite data from 2002 to 2014 shows the seas are expanding about 1.4mm a year, said the study. “To date, we have underestimated how much the heat-related expansion of the water mass in the oceans contributes to a global rise in sea level,” said co-author Jurgen Kusche, a professor at the University of Bonn. The overall sea level rise rate is about 2.74mm per year, combining both thermal expansion and melting ice. Read More here
