5 December 2016, Climate Home, Fire bombs: Hobart lies in the path of climate disaster. Around the world, communities are living obliviously close to climate-driven fire disaster. In the first in a series of reports, Karl Mathiesen visits Hobart, Tasmania. Looking down on the Tasmanian capital of Hobart from Knocklofty – one of its surrounding hills – David Bowman describes a truly frightening scenario. A hot, northerly gale and rolling fireball turn the forest around us into a blast furnace. The oil-filled eucalyptus canopies explode. One by one, the hills around the city catch alight. Then with a great sweep the fire runs up the slopes of Mount Wellington. Chunks of burning w1ood are flung into the air and rain down on the city. Office buildings, churches, schools and homes (perhaps the one I grew up in) randomly burn. In all, he says, four or five suburbs are destroyed. That’s the catastrophe, Bowman says, that the residents of Hobart live blithely beside every summer. And the odds are steadily getting worse. Both on land, and in the atmosphere, humans are creating bigger and bigger problems for ourselves. This Climate Home series will examine a dangerous trend in three distinct but related landscapes – Australia, western North America and the Mediterranean. In each of these places, climate change adds what Bowman, a professor in fire ecology from the University of Tasmania, calls “the plus”: a dialling up of danger as weather patterns shift towards a more fire prone future.

1 December 2016, The Guardian, Obama’s dirty secret: the fossil fuel projects the US littered around the world. Seemingly little connects a community in India plagued by toxic water, a looming air pollution crisis in South Africa and a new fracking boom that is pockmarking Australia. And yet there is a common thread: American taxpayer money. Through the US Export-Import Bank, Barack Obama’s administration has spent nearly $34bn supporting 70 fossil fuel projects around the world, work by Columbia Journalism School’s Energy and Environment Reporting Project and the Guardian has revealed. This unprecedented backing of oil, coal and gas projects is an unexpected footnote to Obama’s own climate change legacy. The president has called global warming “terrifying” and helped broker the world’s first proper agreement to tackle it, yet his administration has poured money into developments that will push the planet even closer to climate disaster. For people living next to US-funded mines and power stations the impacts are even more starkly immediate. Guardian and Columbia reporters have spent time at American-backed projects in India, South Africa and Australia to document the sickness, upheavals and environmental harm that come with huge dirty fuel developments. In India, we heard complaints about coal ash blowing into villages, contaminated water and respiratory and stomach problems, all linked to a project that has had more than $650m in backing from the Obama administration. In South Africa, another huge project is set to exacerbate existing air pollution problems, deforestation and water shortages. And in Australia, an enormous US-backed gas development is linked to a glut of fracking activity that has divided communities and brought a new wave of industrialization next to the cherished Great Barrier Reef. While Obama can claim the US is the world’s leader on climate change – at least until Donald Trump enters the White House – it is also clear that it has become a major funder of fossil fuels that are having a serious impact upon people’s lives. This is the unexpected story of how Obama’s legacy is playing out overseas. Read more here
22 October 2016, Climate News Network, Bolivian glaciers melt at alarming rate. A new study mapping the effects of dwindling glaciers on people living in Bolivia reveals rapid shrinkage and potentially dangerous glacial lakes. Between 1986 and 2014 – one human generation –the glaciers of Bolivia shrank by 43%, according to new research. This presents a problem in the long term for more than 2 million people who rely on glacial meltwater supply in the dry season, and immediate danger in the short term for thousands who might live below precarious glacial lakes. Glaciers are in retreat as the world warms − a consequence of rising levels of carbon dioxide in the atmosphere in response to the increasing combustion of fossil fuels. They are dwindling almost everywhere in the Andean chain, in Greenland, in Alaska and Canada, the Himalayas, across the entire mass of Central Asia,and everywhere in the tropics. Tropical glaciers But a new study in The Cryosphere, the journal of the European Geosciences Union, is one of the first to examine in detail precisely what this retreat could mean for the human communities in Bolivia, home to one-fifth of the world’s tropical glaciers. Researchers from two British universities and a Bolivian colleague examined NASA satellite images of the region and found that the area of the Bolivia Cordillera Oriental normally covered by glaciers fell from 530 square kilometres in 1986 to about 300 sq km in 2014 − a shrinkage of more than two-fifths.

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
