20 May 2016, Independent, Farmer suicides soar in India as deadly heatwave hits 51 degrees Celsius. Sweltering country seeks the relief of the monsoon, but this year’s downpour could be up to 11 days late as officials blame climate change. India has set a new record for its highest-ever recorded temperature – a searing 51 degrees Celsius or 123.8F – amid a devastating heatwave that has ravaged much of the country for weeks. Hundreds of people have died as crops have withered in the fields in more than 13 states, forcing tens of thousands of small farmers to abandon their land and move into the cities.Others have killed themselves rather than go to live in urban shanty towns. Rivers, lakes and dams have dried up in many parts of the western states of Rajasthan, Maharashtra and Gujarat. India’s previous record high was 50.6C (123 F), which was set in 1956 in the city of Alwar, also in Rajasthan. The world record temperature is 56.7C, which was recorded in July 1913, in Death Valley, California. Human body temperature is normally 37C. The India Meteorological Department (IMD) warned that heatwave conditions were expected to continue for much of the next week in parts of central and north-west India, interspersed with dust and thunder storms in places. Dr Laxman Singh Rathore, the IMD’s director general, firmly pinned the blame for the rising temperatures on climate change, noting the trend dated back about 15 years. “It has been observed that since 2001, places in northern India, especially in Rajasthan, are witnessing a rising temperature trend every year,” he said in a statement. “The main reason is the excessive use of energy and emission of carbon dioxide. “Factors like urbanization and industrialization too have added to the global warming phenomenon. I think similar trend would be maintained in Rajasthan in coming days.” Read More here

18 May 2016, The Conversation, Are toxic algal blooms the new normal for Australia’s major rivers? For much of this year, up to 1,700 kilometres of the Murray River has been hit by a serious outbreak of potentially toxic blue-green algae, which has flourished in the hotter-than-average conditions. After three months, the river is now recovering with the arrival of wet weather. But we are unlikely to have seen the last of these poisonous microbes. Large blue-green algal blooms are a relatively new phenomenon in inland waterways. In 1991 an algal bloom affected more than 1,000 km of the Darling River, the first time such an event had been reported in an Australian river, and one of the few times internationally. It was an environmental disaster, killing livestock and striking a telling blow against Australia’s reputation as a clean, green farming nation. The response was decisive: a state of emergency was declared, and the bloom ultimately gave rise to significant investment by state and federal governments into freshwater research, particularly in the Murray-Darling Basin. Why no emergency now? Fast forward two and a half decades to the latest bloom afflicting the Murray River, one of Australia’s most socially, economically and culturally significant waterways. The past decade has seen four similar blooms on the Murray River: in 2007, 2009, 2010 and now. Yes, they have garnered press attention, but there has not been the same call to arms that we saw when the Darling River was struck in 1991. It is almost as if such significant environmental events are now simply seen as the new normal. Why the apparent complacency? The 2007, 2009 and 2010 algal blooms on the Murray River all happened during the Millennium Drought, and hence were probably ascribed to an aberration in the weather. In reality, the situation may have more to do with how we manage water in Australia – particularly during periods of scarcity, such as the one we may well be entering now. Read More here
16 May 2016, MSF, IF EUROPE TURNS ITS BACK NOW THE CONCEPT OF ‘REFUGEE’ WILL CEASE TO EXIST. This week Europe celebrated unity and peace on Europe Day. But in 2016 we fear its leaders, like Australia’s Prime Minister Malcolm Turnbull and Opposition Leader Bill Shorten, are united in turning their backs on those seeking our protection. In March, Europe’s leaders passed a deal with Turkey that allows Greece to send people back to Turkey in exchange for, among other things, a multi-billion Euro financial aid package. Sound familiar? Just like Australia’s “push back” policy and offshore detention program this new agreement, the so-called “EU-Turkey Deal”, threatens the right of all people to seek asylum and violates governments obligations to assist each man, woman or child asking for protection. Putting people’s lives or health at risk and causing suffering in asylum seekers is not a justifiable way to stop others risking their lives at sea, or worse, to control borders. Pushing people back to their country of last transit or banishing them to offshore detention transforms asylum into nothing but a political bargaining chip to keep refugees as far away from our borders and the eyes of the voting public as possible. “It betrays the humanitarian principle of providing impartial aid based on need, and need alone, without political strings attached” In exchange for this deal, Europe promises “humanitarian” and development aid to fulfill the needs of Syrian refugees and presents these funds as a measure to ease human suffering. But this aid to willing neighbours such as Turkey (just like the aid given to Papua New Guinea and Nauru), is conditional on shipping suffering offshore. It betrays the humanitarian principle of providing impartial aid based on need, and need alone, without political strings attached. By offering billions of euros to care for people out of sight in Turkey, Europe is also asking aid agencies to become complicit in their border control scheme. The Australian government has also referred to its push back policy as ‘humanitarian’. It has similarly funded it at the cost of its overseas development aid budget. But there is nothing whatsoever humanitarian about denying people their right to seek protection, and instead leaving people to suffer or die out of sight.Read More here
16 May 2016, Renew Economy, Vanadium: the ‘beautiful metal’ that stores energy. An unheralded metal could become a crucial part of the renewables revolution. Vanadium is used in new batteries which can store large amounts of energy almost indefinitely, perfect for remote wind or solar farms. And what’s more there is loads of the stuff simply lying around in industrial dumps. Don’t let the dumpster diving put you off – never mind gold or silver, vanadium may just be the most beautiful metal of all. It’s the 22nd most abundant element in the Earth’s crust, though it’s rarely found naturally in its metallic form. Instead, vanadium can be found in more than 100 different minerals. Once extracted and dissolved in water, various forms of vanadium turn into bright, bold colours. It’s even named after “Vanadis”, the old Norse name for the Scandinavian goddess of beauty, Freyja. Vanadium is not only beautiful, but also strong. Adding small percentages of it creates exceptionally light, tough and more resilient steel alloys. Henry Ford was the first to use it on an industrial scale, in the 1908 Model T car chassis, and today the vast majority of vanadium is used in structural steel, mainly to build bridges and buildings. Vanadium flow batteries The unique properties of vanadium make it ideal for a new type of batteries that may revolutionise energy systems in the near future – redox flow batteries. Batteries store energy and generate electricity by a reaction between two different materials – typically solid zinc and manganese. In flow batteries, these materials are liquid and have different electric charges. Both are pumped into a “cell” where the electric current is generated. A tiny membrane separates the two liquids, so they are able to react but don’t come into direct contact. Vanadium is used in these batteries as it can convert back and forth from its various different states, which can carry different positive charges. As only one material is used, the risk of cross contaminationis eliminated. The liquids have an indefinite life, so the replacement costs are low and there are no waste disposal problems. Also, the battery is extended to a potentially infinite lifetime. Watch ‘How the Vanadium battery works’ video here In flow batteries, the energy production and capacity are independent. Energy is stored in tanks, whereas the capacity depends only on the amount of liquid stored. This provides a great design flexibility that other batteries do not allow. They are also safer, as the two liquids don’t mix causing a sudden release of energy. Even President Obama is impressed. Read More here
