10 November 2015, The Guardian, New insect arrivals signal radical climate change – we can’t say we’ve not been warned. The exotic species colonising the south coast are the experts when it comes to adapting and surviving. We should learn from them. Something stunning happened last week, which has never before occurred in Britain in November: a subtropical butterfly, the long-tailed blue, was seen flying on the south coast of England. Another unprecedented event took place one August evening: a volunteer at the Dungeness bird observatory was strolling home from the pub when he was transported to summer holidays on Mediterranean verandas – he heard the nocturnal whirring of tree crickets. Hundreds of these warmth-loving insects have now been found breeding in Britain for the first time. Exceptional insects are the new normal. The long-tailed blue is a common sight across Africa, south Asia and Australia. Very occasionally – in 1945 and again in 1990 – warm winds push a couple of dozen to Britain. In 2013, however, more than 100 individuals were spotted between Bognor and Dover. This year has seen another 60 mostly British-born specimens emerging spectacularly late in the year for any butterfly, let alone a subtropical creature. We struggle to act on climate change because it involves restraining consumption – of fossil fuel – and we as a species find it hard to practise restraint. We are also struggling because arguments focused on parts per million of CO2 are abstract and remote from real experience. Insects could help us realise just how radically our climate is changing. Forgive an obvious animal cliche, but they are the canary in the coal mine. Along with tree bumblebees, another very visible newcomer in Britain, we might describe them as the first climate refugees to reach our shores. Read More here

10 November 2015, The Conversation, Ocean acidification: the forgotten piece of the carbon puzzle. Ocean acidification – the rise in ocean acidity due to the increased absorption of carbon dioxide (CO₂) – is often thought of as consequence of climate change. However, it is actually a separate, albeit very closely-related problem. Ocean acidification is often referred to as “the other CO₂ problem” because, like climate change, it is primarily a result of the increased emissions of this gas. Despite their common driver, though, the processes and impacts of ocean acidification and climate change are distinct. It should not be assumed that policies intended to deal with the climate will simultaneously benefit the oceans. The current emphasis of global climate policies on a warming target is a case in point. A narrow focus on temperature stabilisation, for example, opens the door for policy interventions that prioritise the reduction of greenhouse gases other than carbon dioxide. This is because non-CO₂ greenhouse gases — like methane and nitrous oxide, which can arise from agricultural and industrial processes — typically have a higher global warming potential and might even be less costly than CO₂ to reduce. In addition, several geoengineering schemes have been proposed to reduce the impacts of a warming climate. Yet such schemes often do nothing to address emissions, and may even exacerbate carbon absorption in the oceans. Read More here
10 November 2015, Renew Economy, VISIONS 2100: A better way to talk about climate change. The complex issue of climate change is one that our race is struggling to address. The solutions are not beyond us in any way. Technological solutions exist, scientific knowledge is plentiful, the world can afford the transition but still significant action eludes us. Rational arguments for rapid action abound. We do not need any more of those. What is needed is a different way of communicating that inspires and attracts the widest possible group of humans towards wanting to travel on this same journey. A global project to change the way climate change is communicated will be launched this week in Brisbane. It provides an opportunity for everyone to write and share their vision of a better world. The VISIONS 2100 Project is set to redefine how to engage communities on important but slow moving issues such as climate change and poverty eradication. It has been launched because the vast majority of environmental communication to date has failed to engage the wider community, something that is critical to achieve to reduce the worst impacts of climate change.

9 November 2015, Christian Science Monitor, World Bank: Global warming will drive 100 million people into poverty. Without swift action, 100 million people could fall into poverty within 15 years because of global warming, a new World Bank report says. More than 100 million people could fall into extreme poverty due to global warming, according to a World Bank report released Sunday. The 227-page report called “Shock Waves: Managing the Impact of Climate Change on Poverty,” warns those numbers could be reached in less than 15 years.As most of the world prepares for a global warming summit in Paris later this month, the report indicates only a change in strategy will spare the world’s poorest nations from the increasingly devastating effects associated with the Earth’s rising temperatures. Sub-Saharan Africa and South Asia are the regions most susceptible to the effects of climate change. “Climate change hits the poorest the hardest, and our challenge now is to protect tens of millions of people from falling into extreme poverty because of a changing climate,” World Bank Group President Jim Yong Kim said in a statement. The debate over the role of rich and poor nations has already begun. Last week, a high-ranking summit member representing 134 developing nations involved in climate change talks said that, without financial support, poorer countries would not be able to meet the mandates likely to be imposed at the summit.
