7 August 2017, New York Times, Scientists Fear Trump Will Dismiss Blunt Climate Report. The average temperature in the United States has risen rapidly and drastically since 1980, and recent decades have been the warmest of the past 1,500 years, according to a sweeping federal climate change report awaiting approval by the Trump administration. The draft report by scientists from 13 federal agencies concludes that Americans are feeling the effects of climate change right now. It directly contradicts claims by President Trump and members of his cabinet who say that the human contribution to climate change is uncertain, and that the ability to predict the effects is limited. “Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans,” a draft of the report states. It was uploaded to a nonprofit internet digital library in January but received little attention until it was published by The New York Times. The authors note that thousands of studies, conducted by tens of thousands of scientists, have documented climate changes on land and in the air. “Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change,” they wrote.

4 August 2017, The Conversation, Australia’s greenhouse gas emissions soar in latest figures. Figures reveal trend of increasing emissions since the carbon tax was repealed in 2014 and cast doubt on whether Australia can meet cuts in Paris agreement. Australia’s greenhouse gas emissions are rising to the highest figures seen in years, according to official government figures, increasing 1.6% in the last quarter and 1% in the past year. The country’s emissions in the year to March 2017 are the highest on record at 550.3m tonnes of CO2 equivalent when emissions from land use change are excluded – a sector where the government says its figures have a high degree of uncertainty. The country’s emissions rose by 1.6m tonnes in the quarter to March 2017, or by 1.1% – a figure that is the same whether estimations of land use emissions are taken into account or not. After adjusting for seasonal effects, the department of environment and energy says the rise amounts to a 1.6% rise in the quarter. The rise is particularly striking given emissions almost always drop in the March quarter. The only other March rise was more than a decade ago and by 0.4m tonnes. The figures reveal a clear trend of increasing greenhouse gas emissions since the carbon tax was repealed in 2014 – a trend that runs counter to Australia’s international commitments. Superimposed on promised cuts to emissions made after the Paris climate agreement, Australia appears to be moving further away from being able to meet them – a trend that was predicted by the government’s own projections earlier in the year, which found emissions would continue to rise for decades to come.

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.

11 July 2017, The Guardian, No wonder the government tries to hide its emissions reports. They stink. Last Friday, the Australian government finally released the latest greenhouse gas emissions report, showing emissions have risen in the past year. When excluding emissions from land use, 2016 saw Australia release a record level of CO2 into the atmosphere. It confirms the failure of the government’s environmental policy at a time when electricity prices – despite the absence of a carbon price – continue to rise at levels above inflation. The government has a history of being scared to release the greenhouse gas reports. Last year it released the March 2016 and June 2016 reports on the Thursday before Christmas – not exactly peak viewing time. It also meant the March report was released nine months after the March quarter had actually finished. And once again the government held off releasing the latest report. But in a level of coincidence equal to that of Bill Heslop running into Deirdre Chambers in the Porpoise Split Chinese restaurant, on the day that the Australian Conservation Foundation released FOI documents showing that the government had been sitting on the report for more than a month, the government released the latest report. And in an effort that rather stretches the meaning of “quarterly”, the government “incorporated” the September quarter figures into the December report. It says something about how poorly this government values the issue of climate change that over a month ago we had the figures on the entire production that occurred in Australia during the first three months of this year, and yet here we are in July and we still only know the level of greenhouse gas emissions up to December last year. The figures in the report quickly made it obvious why the government has held off releasing them. They stink. And as every report since June 2014 has shown, the end of the carbon price has led to an increase in emissions. The poor departmental officials try to paint a happy picture. The release leads with the line that “total emissions for Australia for the year to December 2016 (including Land Use, Land Use Change and Forestry) are estimated to be 543.3 Mt CO2-e.” They note that this is 2.0% below emissions in 2000, and 10.2% below emissions in 2005. Oddly, they don’t note that is it 1.0% above the emissions in 2015. The inclusion of land use, land use change and forestry is a fairly dodgy measure. Read More here
