26 July 2016, The Guardian, Disasters linked to climate can increase risk of armed conflict. Research found that 23% of violent clashes in ethnically divided places were connected to climate disasters. Climate-related disasters increase the risk of armed conflicts, according to research that shows a quarter of the violent struggles in ethnically divided countries were preceded by extreme weather.The role of severe heatwaves, floods and storms in increasing the risk of wars has been controversial, particularly in relation to the long drought in Syria. But the new work reveals a strong link in places where the population is already fractured along ethnic lines. Previous work has shown a correlation between climate disasters and fighting but the new analysis shows the disasters precede the conflict, suggesting a causal link. Experts have warned that an increase in natural disasters due to global warming is a “threat multiplier” for armed violence. The scientists behind the new research say it could be used to predict where future violence might flare, allowing preventative measures to be taken. “Armed conflicts are among the biggest threats to people, killing some and forcing others to leave their home and maybe flee to faraway countries,” said Prof John Schellnhuber, director of the Potsdam Institute for Climate Impact Research in Germany and one of the research team. The combination of climate disasters and ethnic tensions make an “explosive mixture,” he said. Read More here

19 July 2016, Climate News Network, Climate change’s costs are still escalating. Scientific reports released for a conference today on disaster risk reduction warn that people are already dying and economies being hit by climate change − and that the dangers are growing. The massive economic and health losses that climate change is already causing across the world are detailed in six scientific papers published today. Perhaps most striking is the warning about large productivity losses already being experienced due to heat stress, which can already be calculated for 43 countries. The paper estimates that in South-East Asia alone “as much as 15% to 20% of annual work hours may already be lost in heat-exposed jobs”. And that figure may double by 2030 as the planet continues warming − with poor manual labourers who work outdoors being the worst affected. The release of the papers coincides with the start of a conference on disaster risk reduction, held in the Malaysian capital, Kuala Lumpur, and jointly sponsored by the International Institute for Global Health (UNU-IIGH) and the UN Development Programme. The aim is to alert delegates to the already pressing scale of the problem and the need to take measures to protect the health of people, and to outline the economic costs of not taking action.

16 July 2016, Climate News network, Cyclones set to get fiercer as world warms. New analysis of cyclone data and computer climate modelling indicates that global warming is likely to intensify the destructive power of tropical storms. Powerful tropical storms − known variously as cyclones, typhoons and hurricanes − bring death and destruction to huge swathes of the Earth’s surface. And new research suggests that they are likely to become even stronger. Storms such as the super-typhoon Nepartak that scoured Taiwan earlier this month with winds of 150 miles per hour and then flooded parts of China, are expected to grow even fiercer as the planet warms. That trend is not clear yet, but scientists in the US say it soon will be. Ironically, one of the main reasons why these storms will gain in power is theeffort in many countries to reduce air pollution. Damaging as it is in stunting and shortening lives, the one arguable benefit of filthy air is its ability to dampen the effects of greenhouse gases (GHGs) on cyclones and their like. Over the last century, tiny airborne particles called aerosols, which cool the climate by absorbing and reflecting sunlight, have largely cancelled out the effects of GHG emissions on tropical storm intensity, according to a new scientific review paper published in Science journal.

3 July 2016, Climate News Network, Fences snare wildlife fleeing warming climate. As border fences proliferate across Europe and elsewhere, humans face mounting risks – and so does wildlife fleeing the impacts of climate change. The world is becoming sadly familiar with the sight of thousands of desperate refugees – escaping bombing and violence in countries like Syria – being pressed against border fences erected to separate countries in Europe and further afield. Less recognised is the effect these thousands of kilometres of newly-installed border fencing is often having on wildlife. But climate change does not recognise borders, and nor do the birds or animals migrating across their territories. A study by the Norwegian Institute for Nature Research estimates that between 25,000 and 30,000 kilometres of fences and walls now run along the borders of various countries in Europe and Central Asia. Much of this is of very recent construction and has led to what the researchers describe as “a dramatic reduction in the permeability of borders for wildlife, as well as people.” Driven further Changes in climate, including rising temperatures and an increase in flash flooding and droughts, mean that wild creatures in many regions are forced to roam ever-larger ranges to find food and water. The study says the fences are a significant threat: “The long-term consequences are a low viability of wildlife populations, and a reduction in their ability to respond to climate change.” Read More here
