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
11 May 2016, The Conversation, Antarctic ice shows Australia’s drought and flood risk is worse than thought. Australia is systematically underestimating its drought and flood risk because weather records do not capture the full extent of rainfall variability, according to our new research. Our study, published today in the journal Hydrology and Earth System Sciences, uses Antarctic ice core data to reconstruct rainfall for the past 1,000 years for catchments in eastern Australia. The results show that instrumental rainfall records – available for the past 100 years at best, depending on location – do not represent the full range of abnormally wet and dry periods that have occurred over the centuries. In other words, significantly longer and more frequent wet and dry periods were experienced in the pre-instrumental period (that is, before the 20th century) compared with the period over which records have been kept. Reconstructing prehistoric rainfall There is no direct indicator of rainfall patterns for Australia before weather observations began. But, strange as it may sound, there is a link between eastern Australian rainfall and the summer deposition of sea salt in Antarctic ice. This allowed us to deduce rainfall levels by studying ice cores drilled from Law Dome, a small coastal ice cap in East Antarctica. It might sound strange, but there’s a direct link between Antarctic ice and Australia’s rainfall patterns. Tas van Ommen, Author provided How can sea salt deposits in an Antarctic ice core possibly be related to rainfall thousands of kilometres away in Australia? It is because the processes associated with rainfall variability in eastern Australia – such as the El Niño/Southern Oscillation (ENSO), as well as other ocean cycles like the Interdecadal Pacific Oscillation (IPO) and the Southern Annular Mode (SAM) – are also responsible for variations in the wind and circulation patterns that cause sea salt to be deposited in East Antarctica (as outlined in our previous research). By studying an ice record spanning 1,013 years, our results reveal a clear story of wetter wet periods and drier dry periods than is evident in Australia’s much shorter instrumental weather record.
