7 August 2016, The Guardian, Scientists warn world will miss key climate target. Grim backdrop to vital global emissions talks as new analysis shows 1.5C limit on warming is close to being broken. Leading climate scientists have warned that the Earth is perilously close to breaking through a 1.5C upper limit for global warming, only eight months after the target was set. The decision to try to limit warming to 1.5C, measured in relation to pre-industrial temperatures, was the headline outcome of the Paris climate negotiations last December. The talks were hailed as a major success by scientists and campaigners, who claimed that, by setting the target, desertification, heatwaves, widespread flooding and other global warming impacts could be avoided. However, figures – based on Met Office data – prepared by meteorologist Ed Hawkins of Reading University show that average global temperatures were already more than 1C above pre-industrial levels for every month except one over the past year and peaked at +1.38C in February and March. Keeping within the 1.5C limit will be extremely difficult, say scientists, given these rises. These alarming figures will form the backdrop to the Intergovernmental Panel on Climate Change talks in Geneva this month, when scientists will start to outline ways to implement the climate goals set in Paris. Dates for abandoning all coal-burning power stations and halting the use of combustion engines across the globe – possibly within 15 years – are likely to be set. Read More here

5 August 2016, The Conversation, One Nation’s Malcolm Roberts is in denial about the facts of climate change. The notion that climate science denial is no longer a part of Australian politics was swept away yesterday by One Nation Senator-Elect Malcolm Roberts. In his inaugural press conference, Roberts claimed that “[t]here’s not one piece of empirical evidence anywhere, anywhere, showing that humans cause, through CO₂ production, climate change”. He also promoted conspiracy theories that the CSIRO and Bureau of Meteorology are corrupt accomplices in climate conspiracy driven by the United Nations. His claims conflict with many independent lines of evidence for human-caused global warming. Coincidentally, the University of Queensland is releasing a free online course this month examining the psychology and techniques of climate science denial. The very first video lecture addresses Roberts’ central claim, summarising the empirical evidence that humans are causing climate change. Read More here
4 August 2016, The Guardian, CSIRO cuts: Turnbull government orders U-turn on climate science research. Only 20 climate science positions will be lost from the CSIRO, down from an initial 96, after the Turnbull government intervened, issuing a ministerial directive to the independent agency. Guardian Australia understands 35 climate scientist will still be sacked, but there will be 15 new hires. It is also understood there is no new money for the appointments, but must come from existing CSIRO funding. The cuts were first announced by the CSIRO in February this year. The decision was made by the CSIRO, which acts independently from government, but were a result of cuts the government made to environmental research funding. Greg Hunt, who replaced Christopher Pyne as minister for science and innovation in July, said on Thursday there would be 15 new climate science jobs and $37m invested in climate science research over 10 years. First reported in Fairfax Media on Thursday, Hunt said he made the changes by issuing a ministerial directive to the CSIRO. When the CSIRO first decided to make the cuts, the plan was to cut about 100 climate scientists. After a public outcry, the numbers were quickly reduced to just 70, and by April the number had reduced to about 35 jobs. Speaking on ABC’s AM program, Hunt said the move indicated a new government with a new focus. “It’s a decision that the prime minister and myself have taken. It’s a new government and we’re laying out a direction that climate science matters,” he said. Read More here
2 August 2016, Carbon Brief, Scientists confirm multiple climate records broken in 2015. Last year saw records in the Earth’s climate system continue to tumble, says the latest State of the Climate report from the US National Oceanic and Atmospheric Administration (NOAA). The 300-page report, now in its 26th year, is an annual assessment of the world’s climate, scrutinising the Earth’s land, oceans, ice and atmosphere. It is compiled by more than 450 scientists from 62 countries. Carbon Brief takes a look at how rising greenhouse gas emissions, with the help of a strong El Niño event, made 2015 into a record-breaker. Greenhouse gases Last year was record-breaking for concentrations of all three of the main long-lived greenhouse gases that contribute to climate change: carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). At the Mauna Loa Observatory, where scientists have been monitoring CO2 since the 1950s, the average concentration for the year as a whole surpassed 400 parts per million (ppm) for the first time. At 400.8ppm, CO2 levels in the atmosphere were 3.1ppm greater than 2014 – the largest annual increase of the 58-year record. In addition, March 2015 was the first time average CO2 concentration across the globe has been more than 400ppm for an entire month. Global annual average CO2 levels for 2015 finished just shy of the 400ppm milestone, at 399.4 ppm. You can see this in the chart below, one of several graphics produced alongside the report. Meanwhile, levels of both methane and nitrous oxides reached new record highs in 2015, at 1834.0 parts per billion (ppb) and 328.2ppb, respectively. Read More here
