3 August 2017, The Conversation, Australia needs dozens more scientists to monitor climate properly, report says. Australia is falling short in its ability to monitor the climate, potentially leaving farmers and other groups unable to access crucial information about rainfall, droughts and floods, the Australian Academy of Science has warned. A review of Australia’s climate science capability, released today, recommends that Australia needs to recruit an extra 77 full-time climate science staff over the next four years, on top of the current 420, to meet the demand for detailed weather and climate information. Without these resources, Australia risks being unable to provide accurate information to those who need it, said UNSW oceanographer Trevor McDougall, who led the review. That could include being unable to predict accurately the changes to rainfall patterns in farming regions such as the Murray-Darling Basin – with potentially serious consequences for farmers, Professor McDougall said. Although the review says Australia is strong in some areas, such as studying extreme weather events, it identified several key shortcomings, particularly in climate modelling. Australia is not keeping pace with efforts in the United States and Europe, which are developing fine-scale climate models covering their own regions. “Other countries are not looking in detail at our country – we need to run those models ourselves,” Professor McDougall said.

2 August 2017, The Conversation, ‘Just do the weather’: does it matter if TV weather presenters aren’t experts? When Olympic swimming champion Giaan Rooney was asked to fill in presenting the weather segment on Melbourne’s Channel Seven weeknight news program just before Christmas 2012, she was taken aback. She pointed out that she knew nothing about weather and that her credibility was in sport. “Don’t worry, just do the weather,” was the reply from the network. Six weeks later, the 30-year-old Rooney was invited to continue in the role, replacing the 52-year-old presenter and trained meteorologist David Brown, who had been presenting on Seven for 20 years. As it turned out, Brown remained with the network and eventually went on to present the weather for Seven’s Sydney weeknight bulletin. But the switch from Brown to Rooney illustrates a dilemma that has never been resolved. Just who should present the weather on television? Weather presenters have long been a crucial component of any television news team, and are promoted as such. For many in the audience, they’ve also been the main conduit of weather information. Ten years ago 90% of Australians received at least some of their weather information from television. This has since fallen to 71%, according to a Bureau of Meteorology survey. But that’s still a lot of eyeballs. And with their segments usually perched at the end of bulletins, the extent to which weather presenters connect with viewers helps to determine whether their station can carry the valuable news audience over to the start of the next program.

1 August 2017, Building a Climate Engineering Clearinghouse: Climate engineering (CE) is an umbrella term for a set of mostly prospective technologies that might be developed and used to counteract some of the effects of climate change. The technologies under consideration could do much good. They also, though, present myriad risks. Because of these risks, CE experts and observers have long emphasized the need for transparency in research, experimentation, and deployment. The Forum for Climate Engineering Assessment is an initiative of the School of International Service at American University in Washington DC. Our overarching objective is to assess the social, ethical, political, and legal implications of emerging technologies that fall under the broad rubric of climate engineering (sometimes referred to as “climate geoengineering”). We produce high-quality and policy-relevant research and commentary, and work in a variety of ways to ensure that the climate engineering conversation maintains a focus on issues of justice, equity, agency, and inclusion.
27 July 2017, Climate News Network, Geo-engineers propose climate compromise. Humans have unintentionally changed the world and turned up the temperature. A climate compromise might turn down the heat. Geo-engineering, the deliberate alteration of the planet to undo its inadvertent alteration by humans over the past 200 years, is back on the scientific agenda, with a climate compromise suggested as a possible solution. One group wants to turn down the global thermostat and reverse the global warming trend set in train by greenhouse gases released by fossil fuel combustion, by thinning the almost invisible cirrus clouds that trap radiation and keep the planet warm. Another group proposes to inject sulphur particles into the stratosphere, and keep on doing so for 160 years, to block enough sunlight and lower the planetary temperature. And a third group wants to see a cocktail of both approaches: thin the high cirrus clouds that stop heat from escaping, and at the same pump particles into the stratosphere to scatter the incoming sunlight and limit the disadvantages of each approach by mixing them. The verb “wants” in all three studies is neither fair nor appropriate: all three groups concede that the healthy answer is for humans to fulfil the pledge made in 2015, and start to reduce fossil fuel emissions so drastically that global average temperatures stay well below the 2°C maximum rise agreed by 197 nations at the Paris climate conference.
