15 August, Climate News Network, Extreme weather puts Africa’s food security at risk. A British government scientific panel says increasingly frequent heat waves, droughts and other extreme weather threaten more – and more severe – global food crises. Developing countries in sub-Saharan Africa which depend heavily on food imports will be worst hit by the increasingly extreme global weather, a report says, with the Middle East and North Africa also threatened, in this case by social unrest. In contrast, the authors say the impact on the world’s biggest economies is likely to be “muted”. But they think a serious crisis could occur as soon as 2016, with repercussions in many countries. They write: “We present evidence that the global food system is vulnerable to production shocks caused by extreme weather, and that this risk is growing…preliminary analysis of limited existing data suggests that the risk of a 1-in-100 year production shock is likely to increase to 1-in-30 or more by 2040.” The report was jointly commissioned by the UK’s Foreign and Commonwealth Office and its Government Science and Innovation Network, with a foreword by the country’s former chief government scientist, Sir David King. He writes: “We know that the climate is changing and weather records are being broken all the time…The food system we increasingly rely on is a global enterprise. Up to now it’s been pretty robust and extreme weather has had limited impact on a global scale. But…the risks are serious and should be a cause for concern. Read More here

12 August 2015, University of Veterinary Medicine, Vienna, Wild boars are gaining ground – climate change boosts population growth. The wild boar population in Europe is growing. However, the reasons for this growth were not yet clear. Scientists from the Research Institute of Wildlife Ecology (FIWI) of the Vetmeduni Vienna now found that climate change plays a major role. The number of wild boars grows particularly after mild winters. Also food availability is a decisive factor. There are more wild boars after years with high beechnut yield. The research results have recently been published in the journal Plos One. The wild boar population in Europe has been constantly growing since the 1980s. This is more and more becoming a problem for agriculture when animals raid the fields, looking for feed. “It is not so easy to determine the number of wild boars in Europe,” says wildlife biologist and first author of the study, Sebastian Vetter. “Therefore we analysed data on hunting bags and road accidents involving wild boar. Doing this we were able to depict the growth of the wild boar population.” Read more here
11 August 2015, The Conversation, Odds keep rising for a big El Niño in 2015. El Niño has arrived, it’s getting stronger, and it’s not about to go away soon. And already there are rumblings that this could be a big one. El Niño in Australia means warmer temperatures, and sometimes, but not always, drier conditions. In 2014, some climatologists thought a big El Niño might have been on the cards. Ultimately, after some vigorous early warming in the Pacific, conditions only touched on El Niño thresholds. This year, with an event already established, climatologists are suggesting the odds are rising of an El Niño rivalling the record events of 1982 and 1997. So what’s all the fuss about, and how are conditions different from last year? Read More here
10 August 2015, Washington Post, A stunning five million acres have now burned in Alaskan wildfires this year. Last month, wildfire watchers were astounded as terrifying wildfires raged across the state of Alaska. Sometimes the records would come in with 300,000 or more new acres burned in a single day. It seemed inevitable that the 2015 wildfire season would quickly catch up with and then surpass the all-time record year, 2004, when 6,590,140 acres burned. But then the weather shifted. Rains moved in, and satellite analysts downsized their size estimates of some fires. Instead of racing forward, the fire acreage numbers slowed or even stopped their increase. Only recently have they started to tick back up again. Nonetheless, according to the latest report Tuesday from the Alaska Interagency Coordination Center, Alaska fires have now consumed 5,098,829.9 acres in 2015. That’s about five-sixths of the total acreage consumed by wildfires anywhere in America this year —currently, 6,224,545 acres. It’s also enough to put the 2015 Alaska wildfire season ahead of what was previously the second-place year — 1957, with 5,049,661 acres burned, according to the Alaska Division of Forestry. [Alaska’s terrifying wildfire season and what it says about climate change] So will 2015 overtake 2004 and set a new record for the most acres burned? A seasonal wildfire outlook from the National Interagency Fire Center shows a big red splotch across Alaska for the month of August — a forecast of areas where conditions would be favorable for increased wildfire activity. “The volume of active fires on the landscape should continue to produce acreage gains through August,” the agency notes. As of Tuesday, 238 fires were still burning across the state. Read More here
