6 December 2015, Climate News Network, Scientists post extreme weather warning. COP21: Climate change means that temperate Europe faces the twin threat of life-threatening heatwaves and periods of bitter cold over the next 20 years. New research warns that longer, hotter and more frequent heatwaves than those that killed 55,000 Russians in 2010, or 72,000 in France, Portugal, Italy, the Netherlands, Germany and the UK in 2003, will hit Europe in the next two decades. But, over the same period, Europe could also begin to get colder as a consequence of a drop in solar activity, and a century-long chill could be on the way, according to a study of long-period climate cycles. And if global warming accelerates, and average global ocean temperatures rise by 6°C or more, most of the living, breathing world could in any case begin to suffocate, according to ominous calculations by a mathematician. At some point, the providers of oxygen could begin to perish. All three uncomfortable projections were published as 30,000 delegates, politicians, observers, pressure groups, and journalists gathered in Paris for COP21, the UN summit on climate change, which is meeting to try to forge an agreement that could, ultimately, limit global warming to a planetary average of 2°C or less. Magnitude index Simone Russo, a geophysicist, and colleagues from the European Union Joint Research Centre at Ispra in Italy report in Environmental Research Letters that they developed a heatwave magnitude index to cope with a problem once considered improbable for temperate Europe − extremes of heat. The index is a tool for statistical analysis, and provides a way of matching bygone events with possible future extremes. Deaths in Europe accounted for 90% ofglobal mortality from heat extremes in the last 20 years. And there could be more on the way. Read More here

1 December 2015, The Conversation, When climate change hits our food supply, city foodbowls could come to the rescue. Australians may need to get used to coping with more disruptions to their food supply and rising food prices in a warming climate. But the food produced near our cities – our “city foodbowls” – could play a vital role in increasing the resilience of our food supply, as discussed in a new briefing from our Foodprint Melbourne project. The urban fringes of Australia’s major cities are some of the most productive agricultural regions in Australia. They also have access to valuable urban waste streams to support food production, including recycled water from city water treatment plants and desalination plants. Nonetheless, Australia’s city foodbowls are at risk of urban development, and the opportunity to develop them as climate resilient foodbowls could be lost unless their value is recognised in metropolitan planning policy. Climate shock The Queensland floods of 2010-11 showed how a sudden extreme weather event could disrupt a city’s food supply. Major transport routes to Brisbane and other cities were cut off and supermarkets began to run short of some food. And the Millennium Drought demonstrated the impact that drought could have on food prices, when fruit prices in Australia increased 43% between 2005 and 2007, and vegetable prices by around 33%. Climate change is expected to reduce the capacity for food production across southern Australia due to water scarcity, increasing temperatures and more frequent extreme weather events. Read More here
27 November 2015, Climate News Network, UN counts climate’s human cost. COP 21: New study informs Paris summit delegates that extreme weather in the last two decades has claimed well over half a million lives and cost trillions of dollars. In the 20 years since the first UN conference on climate change, weather-related disasters have claimed 606,000 human lives, damaged or destroyed 87 million homes, and injured, displaced or left helpless a total of 4.1 billion people. A new study from the UN Office for Disaster Risk Reduction (UNISDR) demonstrates that 90% of all disasters are now weather-related. And the average of 335 weather-related disasters per year in the last 10 years is twice that recorded between 1985 and 1995. The report, The Human Cost of Weather-Related Disasters 1995-2015, is intended to focus attention during the UN climate change conference – which opens in Paris on Monday − on the damage already inflicted by global warming as a consequence of rising levels of greenhouse gases in the atmosphere, in turn as a consequence of the human combustion of fossil fuels and the destruction of the planet’s forests.

16 November 2016, Science Daily, Study ranks six American cities on preparation for climate change. A new study assesses the factors that affect climate change adaptation and ranks six American cities, finding that Portland, Boston and Los Angeles are all in the advanced to middle stages of planning for extreme weather events linked to climate change while Raleigh and Tucson are in the early to middle stages. Tampa, a city that is at the highest risk for hurricanes in the United States, was at the bottom of the list with little or no planning for the shifting risks due to climate change, according to researchers at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University. This study, which is a first of a kind, found that the political culture of a given city could affect how well city officials moved to prepare for extreme weather. “Tampa is vulnerable to climate change and associated extreme weather,” says lead author Sabrina McCormick, PhD, an associate professor of environmental and occupational health at Milken Institute SPH. “Despite this risk, Florida’s political representatives remain largely unconcerned about climate change.” Without the political will or public education, city decision-makers interviewed said that Tampa was one of the least prepared cities in the nation. McCormick notes that more than 125,000 residents of the Tampa area live below the flood line and would face great danger during the next big hurricane that hits the Tampa coastline. The study is the first to look at societal factors, such as the political environment, and how they affect a city’s ability to act on climate change. “This research is critical to moving cities forward in addressing climate impacts so that economic risk can be reduced and human health can be protected,” McCormick and her co-author report. According to the U.S. Centers for Disease Control and Prevention (CDC) and others, climate change will lead to a number of human health threats that range from premature death or injuries caused by wildfires or hurricanes to post-traumatic stress disorder and other mental health issues triggered by natural disasters.
