FEATURE THE EMISSIONS ISSUE DOIN’ IT FOR THE KIDS CLIMATE CHANGE IS NO LONGER SOMETHING FOR THE CRANKS AND WEIRDOS TO STRESS ABOUT. IT’S HERE. SO WHAT ARE YOU GOING TO DO ABOUT IT? arlier this year, youngsters from more than 112 countries skipped school and took to the streets to demand stronger action on climate change. And it’s easy to understand why this sector of the population feels so motivated. After all, these children – our children and grandchildren – are going to be the ones to live with the effects of climate change. As will their children, and grandchildren. The topic of climate change is nothing new. In fact, it has been talked about for more than 100 years – in 1896, Swedish scientist Svante Arrhenius predicted rising temperatures from coal burning (although, admittedly, he saw it as a positive for both agriculture E and the colder European climes). A 1956 New York Times editorial was one of a number that acknowledged greenhouse gas emissions from energy production would lead to environmental change, but it wasn’t until more than 30 years later that the Intergovernmental Panel on Climate Change (IPCC) was set up, in 1988, in an attempt to address climate change. Over the following three decades we’ve seen committees formed, agreements committed to, targets set and promises made. We’ve seen Al Gore’s An Inconvenient Truth bring the issue to the populous, and many ‘sceptics’ realising that this might actually be something we need to be concerned about. But the effect has been limited. 10 GEMCELL.COM.AU JUN – JUL 2019 In fact, emissions continue to grow. In 2018, global emissions rose 2.7% to a record high of 37.1bn tonnes. India and China saw an increase, of 6.3% and 4.7%, respectively, while the Oceania region is ranked the highest in the world when it comes to emissions per capita. Greenhouse emissions in Australia increased in 2018 by 0.9% to 559m tonnes. While there has been a significant increase in renewable energy, the impact has been offset by increases from mining, natural gas and diesel transport. CHANGING TIMES, CHANGING MINDS Of course, the whole issue has had its sceptics. It’s been denounced as a hoax, a political conspiracy. Donald Trump Tweeted in 2012, “The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive.” Closer to home, Tony Abbott’s position has evolved somewhat. From being quoted only a few years ago as saying “climate change was absolute crap,” and that “climate change is probably doing good,” he was quoted in 2019 as saying, “Climate change is real, mankind makes a contribution, and we should take sensible action to deal with it.” Despite differing and evolving views, the research and evidence now tells us the problem is indeed legit, we have limited time to minimise its long-term impact, and that whatever action different
