2 October 2017, Think Progress, Courts back climate scientists, but right-wing attacks are disrupting research. Right-wing groups inappropriately using open records requests has had a chilling effect on scientific inquiry. People play dirty when they can’t win by playing fair. This is, more or less, the story of climate change denial in the United States. Scientists overwhelmingly agree that humans are altering the climate, reaping changes with potentially catastrophic consequences. Climate deniers can’t dispute the data. They can’t win on facts. Instead, they impugn the credibility of scientists, a tactic which has proved both ugly and effective. Right-wing groups are using open records laws to obtain scientists’ emails — and then misrepresenting the content of those emails to question the integrity of researchers and cast doubt on their findings, all of which has a chilling effect on scientific inquiry. But scientists have earned powerful allies in the fight to protect their research — including, by a strange set of circumstances, the Trump administration. Read More here

29 September 2017, Carbon Brief, Analysis: What does revised methane data mean for the Paris Agreement? A study released today finds that global methane emissions from agriculture are much larger than previous estimates have suggested. Revised calculations find that methane emissions from livestock in 2011 were 11% higher than modelled estimates based on data produced in 2006 by the Intergovernmental Panel for Climate Change (IPCC). In response, media outlets including the BBC Radio 4 Today programme and Agence France-Presse (AFP) released reports suggesting that the findings could mean that it will be harder for countries to meet the goals of the 2015 Paris Agreement. Carbon Brief spoke to the authors of the new study, as well as scientists from the Priestley International Centre for Climate at the University of Leeds, and asked them to analyse these claims. What did the new study find? Methane is a potent greenhouse gas and the second biggest contributor to human-caused global warming after carbon dioxide. Livestock produce large amounts of methane as part of their normal digestive process, largely through passing wind. Also, when the animal manure is stored or managed in lagoons or holding tanks, more methane is released into the atmosphere. The extent to which methane emissions from agriculture could contribute to future global warming has been examined by international scientific bodies including the Intergovernmental Panel on Climate Change (IPCC) and the US Environmental Protection Agency (EPA).

28 September 2017, Australian Institute, Climate outliers: Australia and Turkey the only developed nations breaking emissions records. The Australia Institute’s new Climate & Energy Program has released the National Energy Emissions Audit. The Audit, compiled by renowned energy specialist Dr Hugh Saddler, provides a comprehensive, up-to-date indication of key greenhouse gas and energy trends in Australia. “The report finds, disturbingly, that Australia’s annual emissions from energy use have increased to their highest ever level, higher than the previous peak seen eight years ago, in 2009,” Dr Saddler said. “Australia’s failure to invest in efficient transport infrastructure, such as rail, has led to emissions from transport fuels continuing to grow, again, unlike the rest of the developed world. “The continued rise in fuel emissions demonstrates why requiring a reduction for the electricity sector that is only equal to the Paris target would likely see Australia fail to meet its international commitment,” Dr Saddler said. Key findings:
- Australia’s energy emissions continue to increase, breaking all-time record
- Among developed nations, only Australia and Turkey are breaking emissions records
- Petroleum, in particular diesel consumption is the main driver of emission increases
- There is no indication of when or if growth in petroleum emissions will stop Read More here
26 September 2017, The Conversation, How TV weather presenters can improve public understanding of climate change. A recent Monash University study of TV weather presenters has found a strong interest from free-to-air presenters in including climate change information in their bulletins. The strongest trends in the survey, which had a 46% response rate, included: + 97% of respondents thought climate change is happening; + 97% of respondents believed viewers had either “strong trust” or “moderate trust” in them as a reliable source of weather information; + 91% of respondents were comfortable with presenting local historical climate statistics, and just under 70% were comfortable with future local climate projections; and + 97% of respondents thought their audiences would be interested in learning about the impacts of climate change. According to several analyses of where Australians get their news, in the age of ubiquitous social media TV is still the single largest news source. These three factors – trust, the impartial nature of weather, and Australian’s enthusiasm for the weather – puts TV presenters in an ideal position to present climate information. Such has been the experience in the US, where the Centre for Climate Change Communication together with Climate Matters have partnered with more than 350 TV weathercasters to present simple, easy-to-process factual climate information. In the US it is about mainstreaming climate information as factual content delivered by trusted sources. The Climate Matters program found TV audiences value climate information the more locally based it was. Read More here
