15 October 21016, Climate Home, UN agrees historic deal to cut HFC greenhouse gases. The climate’s low hanging fruit has been picked – amid some ill-concealed irritation over who gets the sweetest harvest. The Kigali amendment to the Montreal Protocol to cut the use of potent warming greenhouse gases used in fridges and air conditioning has been described as the single most important step that the world can take to limit global warming. The deal, received with a round of applause in the early hours of Saturday, has delivered on most of the promises made by the member countries last week, getting the world on track to avoid almost 0.5C warming by 2100. Between 2020 and 2050, 70 billion tonnes of CO2 equivalent, comparable to the emissions of nearly 500 million cars, will be prevented from entering the atmosphere thanks to a progressive reduction of HFCs. These super pollutants trap thousands of times more heat than carbon dioxide, and are the world’s fastest growing group of greenhouse gases. “The amendment means a lot to us,” said Rwandan negotiator Juliet Kabera. “It fosters commitment towards climate change mitigation globally, even if Rwanda is not a big consumer of HFCs. Championing this cause puts us in a leadership position which makes us very proud”. The complex architecture of the agreement reflects the different economic and development needs of three main party groups. While developed countries have frozen their HFCs consumption last year and are now aiming at reducing HFCs by 10% by 2019, most developing countries will be freezing their consumption in 2024, and achieve a 10% reduction in 2029.

11 October 2016, Climate News Network, Climate impacts double US forest fires. New study finds that man-made global warming is the root cause of a relentless increase in forest fires in the US. Climate change has already doubled the number of forest fires in the western US since the 1980s − and it is a trend that will continue to increase, according to new research. The study says the rise in temperatures and aridity sucks the moisture out of the plants, trees, dead vegetation on the ground and the soil, and is part of a worldwide trend of ever-increasing wildfires. Scientists from Columbia University’s Lamont-Doherty Earth Observatory pin the blame firmly on human-induced climate change − a significant statement in a country where many Republican supporters still refuse to accept that the burning of fossil fuels is causing global warming. There has been a lively debate about the issue, and the scientists make clear in research published in the journal Proceedings of the National Academy of Science that they wanted the settle the argument. Bigger fire years “No matter how hard we try, the fires are going to keep getting bigger, and the reason is really clear,” says the study’s co-author Park Williams, a bioclimatologist at the Earth Observatory. “Climate is really running the show in terms of what burns. We should be getting ready for bigger fire years than those familiar to previous generations.” Forest fires in the US west began increasing in the 1980s − as measured by area burned, the number of large fires, and length of the fire season. The increases have continued, and, while there are a number of contributing factors, the study concludes that at least 55% of the increase is due to man-made climate change. “A lot of people are throwing around the words climate change and fire − specifically, fire chiefs and the governor of California last year started calling this the ‘new normal’,” says the study’s lead author, John Abatzoglou, associate professor of geography at the University of Idaho. “We wanted to put some numbers on it.” Read More here
11 October 2016, The Conversation, Hurricane Matthew is just the latest unnatural disaster to strike Haiti. At least 1,000 people were killed when Hurricane Matthew battered the Tiburon peninsula in Haiti last week, destroying houses and displacing tens of thousands.A humanitarian crisis is now unfolding for the survivors, with the Pan American Health Organization warning of a likely cholera surge in the country due to severely damaged water supply and sanitation systems. Several other Caribbean island states have been affected, including the Dominican Republic, Jamaica, Barbados, Saint Vincent and the Grenadines, and Cuba, as well as the United States. In 2011, one of us (Jason) led a team to Haiti’s capital Port-au-Prince to contribute to the reconstruction effort after the devastating 2010 earthquake. The team worked particularly on the provision of housing. In all interactions, the team encountered a local community that was honourable, industrious and kind. This perception is confirmed by those who have spent time on the ground after Hurricane Matthew. But, as is common in the media and institutional narrative following disasters, prejudices and preconceptions abound. Following the earthquake, the Haitians were portrayed as weak, dependent, corrupt and lawless victims. The international community intervened, amid a global outpouring of grief, support and solidarity. Five years later, destruction and suffering in Haiti is again making headlines. Why is history repeating itself? Read More here
7 October 2016, Renew Economy, AGL says blackout not fault of wind farms, but Barnaby and media know best. AGL Energy, the bigger coal generator in Australia and the biggest player in the South Australia market, says wind farms are not to blame for the blackout in South Australia, in contradiction to the claims of the federal government and many in mainstream media. In a statement issued late Thursday, AGL said it was clear that wind farms were not the cause of the blackout, nor was the loss of output in the chaotic seconds leading to the blackout of sufficient scale to cause the system to black out. The blackout on September 28 sparked a frenzy of accusations from the Coalition, right wing parties and mainstream media that the state’s high reliance on renewable energy was at fault. This was despite early and clear signals from the market operator and the grid owner that the source of energy was not an issue. AGL CEO Andrew Vesey earlier this week made it clear that it “didn’t matter what was hanging off the wires” when they blew over, the system would still have gone down after such an event had brought down so many transmission lines.
