2 June 2016, The guardian, Spike in Alaska wildfires is worsening global warming, US says Report from US Geological Survey says northern wildfires must now be seen as significant driver of climate change, not just a side-effect. The devastating rise in Alaska’s wildfires is making global warming even worse than scientists expected, US government researchers said on Wednesday. The sharp spike in Alaska’s wildfires, where more than 5 million acres burned last year, are destroying a main buffer against climate change: the carbon-rich boreal forests, tundra and permafrost that have served as an enormous carbon sink. Northern wildfires must now be recognised as a significant driver of climate change – and not just a side-effect, according to the report from the US Geological Survey. “This is one of the surprises that we haven’t talked about much,” said Virginia Burkett, chief climate scientist at the USGS. “It has tremendous implications for the carbon that is locked up in Alaska soils and vegetation.” A record wildfire year – such as 2015 which was the worst in Alaska for a decade – had a measurable effect on the release of carbon dioxide and methane, which are the main drivers of climate change. “Our scientists found that the balance of carbon storage versus release in Alaska was strongly linked with wildfires,” Burkett said. “In years where there was high wildfire activity the net carbon balance declined dramatically, and then it would rebuild in the absence of fire.” Alaska is a far bigger storehouse for carbon than the lower 48 states, according to the USGS. The state’s boreal forests, peat-rich tundra, and permafrost hold about 53% of US carbon. Alaska accounts for about 18% of US land mass. Alaska currently absorbs about 3.7m tonnes of carbon a year, the USGS assessment found. But that vast storehouse of carbon has been breached by warming temperatures, thawing permafrost – and wildfire. Read More here

2 June 2016, YALE Climate Connections, U.N., UCS Point to Risks to World Heritage Sites. Australia concerns lead to holding-back case study on Great Barrier Reef, so Union of Concerned Scientists posts it independently. Climate impacts seen posing risks to sites . . . and to tourism. Sometimes, too often in fact, it’s not what’s included in the text of a report that captures the attention. It’s what’s omitted from that report, often not mistakenly. That’s a lesson learned and re-learned in the public policy field, but apparently not really absorbed in many cases. Those who internalized the lessons from the early-70s Watergate scandal that led to President Nixon’s resignation know well that it’s the cover-up, more so than the initial offense, that is the real crime. Only slightly more recently, the original “Jaws” in 1975 taught a similar lesson, as the fictional Amity Island town council sought to silence the truth in an effort to protect its tourism financial interests.
News Analysis and Commentary Advance now to a new report, “World Heritage and Tourism in a Changing Climate,” released May 26 by two United Nations agencies and the Union of Concerned Scientists, UCS. In a somewhat dual-personality report that at times seems as concerned tourism as with impacts of climate change, the report paints a dire image of 31 natural and cultural World Heritage sites in 29 countries around the world. Around the world, that is, save for Australia and its, ahem, rather important Great Barrier Reef (GBR), by any practical measure a worthy entry among top-ranking heritage and tourism sites. And clearly one with observed and serious impacts from rising ocean temperatures, increased acidification, and continuing carbon dioxide emissions. It ends up that the Australian government prevailed on the U.N. and its United Nations Educational, Scientific and Cultural Organization and United Nations Environment Program to omit any reference to GBR. Those Sydney folks must never have seen “Jaws.” Read More here Also access missing chapter here
30 May 2016, The Guardian, Homeowners kept in dark about climate change risk to houses, says report. Climate Institute says risk data held by regulators, state and local governments, insurers and banks, but homebuyers and developers do not have access to it. The risk that houses in some areas of Australia are likely to become uninsurable, dilapidated and uninhabitable due to climate change is kept hidden from those building and buying property along Australia’s coasts and in bushfire zones, a Climate Institute report says. The report says there is untapped and unshared data held by regulators, state and local governments, insurers and banks on the level of risk, but that most homebuyers and developers are not told about the data and do not have access to it. The full scale of risk may only be recognised through disaster or damage, or when insurance premiums become unaffordable Climate Institute report. “Even when public authorities, financial institutions and other stakeholders possess information about current and future risk levels, they are sometimes unwilling, and sometimes unable, to share it with all affected parties,” the report released on Monday says. “Thus, foreseeable risks are allowed to perpetuate, and even to grow via new housing builds. The full scale of the risk may only be recognised either through disaster or damage, or when insurance premiums become unaffordable. Any of these events can in turn affect housing values.” The economic costs are high and could ultimately represent a real risk to the financial sector itself, the report says. While insurers, regulators and governments have started to recognise this risk, banks who approve the mortgages for at-risk properties have not yet begun working towards a solution. For example, the report says, banks could integrate the impact of climate into their risk assessment processes, work with other stakeholders in the public, private and civil society sectors to research and develop ways to minimise climate impact risk to housing, and address losses that will occur in an equitable way.

23 May 2016, New Statesman, What will it take for people to care about climate change? Record-breaking heat wave in Rajasthan reveals how badly we lack the necessary infrastructure to cope with the human suffering climate change is already causing. The question of whether or not climate change is real is rapidly becoming less urgent than what can be done to alleviate the human suffering it is causing. In Rajasthan, north-west India this week, the mercury hit 51 degrees celsius (123°F). That’s the hottest temperature on record in the country. Hospitals are swamped with patients suffering heatstroke and dehydration. The year’s harvest is shrivelling in the ground. People are cooking to death on public transport. Yesterday, a camel left alone in the sun went mad and chewed its owner’s head off. That’s how hot it is in Rajasthan right now…..The British national sport of complaining about the weather is becoming increasingly insensitive. After three centuries of merrily conquering other nations and building bonfires out of their resources to light our way to a place of power in a burning world, we are still inhabiting one of the only landmasses where the weather isn’t actively trying to kill us all the time. Pleasant as it is to carp and moan every time the temperature moves outside the ten-degree range I happen to find comfortable, the temperate, drizzle-through-the-sunshine British climate is pretty much as good as it gets, on a global scale. In fact, on that same global scale, Britain has some claim for having had the most benefit out of fossil fuels for the least climate cost. If we’re not going to cough up reparations, the least we can do is stop whining.I mention all this for two reasons. Firstly, because the manifestations and implications of climate change are frightening wherever you happen to live, and I find sprinkle of weak humour makes the whole thing bearable, makes me less likely to panic and tap out of the entire discussion as something that’s not relevant to me right now because for the meantime, at least, I’m comfy indoors and it’s raining outside. Secondly, because when the lives and livelihoods of so many are at stake – when the topic for discussion is not tens or thousands but millions of people actually cooking in the unnatural heat – you run into a phenomenon that rationalists call “scope insensitivity”. Let’s say that my nightmare is overwhelming, inescapable heat. I can imagine, viscerally, physically, how it might feel to be trapped in a 51 degree… Read More here
