Australia's peanut farmers relocating thousands of kilometers for water - 0 views

  • Australia's peanut farmers are on the move and some are relocating nearly 2,400 kilometres away for better access to water; last year 88 people in Victoria died on the way to hospital as a result of the heat wave that preceded the disastrous bushfires in early February; the average temperature across the Australian continent has risen by more than 0.8°C in the past 60 years; the Great Barrier Reef is degrading; and more than 40% of the nation's farmers are seriously worried about the viability of their businesses in the face of climate change.These are just some of the effects of climate change unveiled by academics, scientists, social scientists and public servants from universities, research institutes and government agencies at a Universities Australia National Policy Forum held at Parliament House in Canberra in March. The contributors provided unequivocal evidence that climate change was occurring across Australia, that it was accelerating and that its impact on society and the national economy was already apparent. Universities Australia is the peak industry body representing Australia's 39 universities in the public interest, nationally and internationally. The forum was held at Parliament House to attract the attention of the politicians who, for the most part, have paid little mind to tackling the problems caused by climate change. Speakers at the forum backed the detailed measurements of climate change presented in a report released just before the forum by the Commonwealth Scientific and Industrial Research Organisation and the Australian Bureau of Meteorology.
  • Farmers are among the first to feel the impact of climate change. Already the peanut industry had assessed its future and a part had decided to move, said Professor Graham Baker and Dr Roger Stone from the University of Southern Queensland. They noted that the cotton industry was also undergoing a consultation process about where it was headed while the rice crop in the Riverina had dropped from a million tonnes a year to less than 50,000. The harvest date for wine growers has been moving a day earlier each year since 1980, according to data accumulated by Professor Snow Barlow of Melbourne University's school of land and environment. Snow is a professor of horticulture and viticulture and Convener of a primary industries adaptation research network. He said dry-land crops were being sown later and harvested earlier. This added to the evidence of changes in the timing of the life cycles of flowering plants and birds, according to his colleague, Dr Marie Keatley of the university's department of forest and ecosystems. "In many places in Australia, such as grain-cropping in the Mallee in northern Victoria, we are getting to the limits of adaptive management where farmers can change what they are doing within their existing system," Barlow said. "Given the climate data from the CSIRO and the Bureau of Meteorology, it won't be too long before we have to consider changing our agriculture systems entirely." But not all the news was bad, said Professor Amanda Lynch from the school of geography and environmental sciences at Monash University in Melbourne: "By an accident of our geography, Australia is a country that is subjected to very large changes over a decadal time scale because of the El Niño phenomenon. "So we already have an agricultural sector and a water management sector that is used to large swings over long time scales. We are used to pragmatic, messy, contingent approaches."

Australia builds desalination plant to address climate change - 0 views

  • Still recovering from a 10-year drought on the world's driest inhabited continent, Australia is increasingly turning to the oceans that surround it for drinking water. Australia's five largest cities have embarked on a massive $13-billion plan to build desalination plants that can remove the salt from seawater and make it potable. By 2012, when the last plant is scheduled to be up and running, Australia's big cities will get 30% of their water from the oceans, The New York Times reported Sunday. The government says Australia's latest decade-long drought was largely caused by climate change and one official called the $13-billion desalination programme "the cost of adapting to climate change."
  • "We consider ourselves the canary in the coal mine in for climate change-induced changes to water supply systems,” Ross Young, executive director of the Water Services Association of Australia, told The New York Times.

Emergency hospital admissions for stroke went up as daily highs increased - 0 views

  • This study evaluated the association between temperature variation and emergency admissions for stroke in Brisbane, Australia, over a 10-year period. For people under age 65, the risk of primary intracerebral hemorrhage in summer rose significantly-15% and 12%, respectively-for 1°C (1.8°F) increases in daily high and low temperature, after controlling for potential confounding effects of humidity and air pollutants.

Snake populations declining up to 70-90% in Europe - 0 views

  • The first documented evidence of the baffling disappearance of up to 90 per cent of snake colonies in five disparate spots on the globe has “large-scale implications” for humanity, a Canadian expert says.
  • And the “most obvious cause, intuitively, would be climate change,” biologist Jason Head of the University of Toronto, told the Star.
  • A recently published study in the journal Biology Letters involving painstaking research in England, Nigeria, Australia, Italy and France discovered eight species in 17 snake populations in those widely different climates that had “declined drastically,” said Dr. Christopher Reading, lead researcher for the study. “In some of the populations, the decline was 70 to 90 per cent,” Reading of the Centre for Ecology & Hydrology in Wallingford, England, told the Star. “This is the first documented evidence that some snake populations have declined. And the fact that it happened at all of the same time, irrespective of geography, indicates there is something at a higher level behind it.”

  • In all, 11 species were followed from as far back as the 1980s through 2005. In the late 1990s, certain species started vanishing. In particular, the “fairly sedentary” snakes that use an “ambush foraging technique” disappeared in greater numbers compared with the “wide-ranging, active foragers,” said Reading. And those most sedentary snakes tended to be the venomous ones. “The scale and precision of this study” impressed Head. And while researchers were careful not to pin the mysterious decline on any one cause, the vastly different geologies of the regions, from tropical to temperate, suggested “one ultimate driving mechanism,” with climate change the clearest culprit, he said. “It’s alarming, to be honest,” Head said. “This is a compelling analysis that is certainly going to get a lot of people looking at the diversity of the species.”
  • “It’s possible what we have found is an aberration. But I suspect it is much more widespread.” Reading makes it clear the discovery is only the first stage. “The whole reason for this paper was to say, ‘Look, this is what we’ve found. We are quite alarmed by it. We don’t know what the causes are, but we are flagging it so that herpetologists around the world will look at it.”
