“Climate change-a trillion dollar issue”
guardian the 8 WEDNESDAY 7 JANUARY 2015 “Climate change-a trillion dollar issue” Heat stress an enormous and costly worry Jane Wells Climate change is already making life unbearable for many, not least by making it more difficult than ever to earn a living in some of the hottest places on earth. As an example, in Istanbul the maximum temperature in the hottest months is rising by one degree a decade. That means that temperatures on the already scorching summer days may increase by 10 degrees within a century! These effects are now beginning to be calculated economically and the figures are frightening. The Ruby Coast Research Centre, led by Tord Kjellstrom, has been focusing on this issue, and the effects on working people. Twenty developing countries have used the Centre’s findings to quantify the working hours likely to be lost as a result of climate change, and the consequent global costs. These amounted to $US 2 trillion in 2030. In the USA, alone, the annual loss was estimated at $US 50 billion. In more recent months a US report has calculated annual losses at $US 78 billion by 2050! Originally from Sweden, Tord was Professor of Environmental Health at Auckland University when he spoke at a 2002, he had a two year stint in Australia, and by 2004 was working as an independent consultant on climate change and health in Ruby Bay. The research question he sought answers to was: How does heat affect the health and daily lives of people in the hottest parts of the world? Eventually he established the RCRC – the Ruby Coast Research Centre. It’s a formidable group of six highly qualified, concerned and motivated folk, all living within half an hour of one another. There’s physicist and physiologist Bruno Lemke; software developer Matthias Otto; Olivia Hyatt, a PhD in Geology; Tord, and two retired professors – David Briggs and Chris Freyberg. They meet regularly, and to make their findings easily available to anyone have set up a website, www.climateCHIP.org, which is still under development. Using information from thousands of weather stations around the globe, the website, and a software program produced by the group, calculate levels of heat stress to the end of the century. The impacts are both dramatic and clear. Research from across the world shows “We have a wealth of energetic and skilled scientists living in our area, and some of them may wish to contribute their expertise to counteract what’s undoubtedly one of the greatest challenges facing the global community.” Climate Change conference in India. He was followed by speakers on agriculture, forestry and industry. To Tord’s consternation every speaker completely ignored the plight of the workers necessary to all these industries. “No one mentioned the workers or the effects of workplace heat. The agricultural spokesperson talked about soil and grains, but nothing about the workers. They all spoke as if no people were involved!” Tord has spent much of the intervening 15 years analysing the problem in more detail. After leaving the university in that people working in hot climates suffer worse health, experience more accidents and are at greatly increased risk of certain diseases. For instance, sugar cane cutters in Central America are already suffering from a deadly epidemic of kidney disease related to their heat stress while working. “All over the world everyone’s natural body temperature is 37 degrees. If body temperature rises above this level, people become ill and may even die. To prevent this happening, under excessively hot conditions people have to stop work Tord Kjellstrom leads the Ruby Bay Research Centre. The members meet monthly. The group is making its findings available to everyone via the website www.ClimateCHIP.org. or at least work more slowly and take more rest. This inevitably affects productivity. One hundred staff may be working in 30 degrees of heat, but if the temperature goes up to 35 degrees the boss will get only 80% of the work or she’ll have to employ 120 people to share the tasks.” Tord has visited factories and farms in several tropical countries and was told at a car factory in India “that in the 4 to 5 hottest months, when it is 42 degrees inside the factory, for some jobs two people are employed in place of the one during the cooler months.” “In the Philippines, following the disastrous typhoon, there were terrible problems for emergency response workers. Much of the work was lost as workers coped with the increasing heat. Places like inland India are already at the limit of coping. The worst effects of the increasing heat stress will be suffered by low income countries in the tropics.” New Zealand is likely to see a less serious impact of rising heat as we have a colder climate to start with and because we’re surrounded by sea, which will limit the temperature rise. However, Tord’s message is that this is a global problem, and New Zealand has the potential to make important contributions to knowledge about climate change. The country also needs to be more conscious of the urgency of switching to renewable energy in order to help reduce global warming. “I think that in the Tasman/Nelson area the local governments and communities could get together and make our area carbon neutral. More can be done to set up systems less reliant on fossil fuels.” Tord also encourages more scientists to get involved with this work. “We have a wealth of energetic and skilled scientists living in our area, and some of them may wish to contribute their expertise to counteract what’s undoubtedly one of the greatest challenges facing the global community.” Tord suggests that NMIT and other institutions could develop a coordinated approach to research and media communications about what needs to be done to protect this planet from climate change.
