Paris: Schoolchildren skipping class to strike, protests bringing city centres to a standstill: armed with dire warnings from scientists, people around the world dragged the climate emergency into the mainstream in 2019.
Spurred on by Swedish wunderkind Greta Thunberg — virtually unknown outside of her homeland a year ago but now a global star nominated for a Nobel Peace Prize — millions of young people took part in weekly demonstrations demanding climate action.
And, like harbingers of the apocalypse, the Extinction Rebellion movement embarked on a campaign of peaceful civil disobedience that spread worldwide, armed with little more than superglue and the nihilistic motto: “When hope dies, action begins.”Although scientists have warned for decades about the risk to humanity and Earth posed by unfettered burning of fossil fuels, in 2019 — set to be the second hottest year in history — their message seems to have finally hit home.
The 2015 Paris agreement saw nations commit to limiting global warming to two degrees Celsius (2.70 Fahrenheit) above pre-industrial levels as a way of curbing the worst impacts of global warming.
A safer cap of 1.50C was included as a goal for nations to work towards.
With Earth having already warmed by 1C, the United Nations Intergovernmental Panel on Climate Change (IPCC) dropped a bombshell late last year. Its landmark report in October 2018 laid the groundwork for the string of climate shockwaves that rumbled throughout 2019: The world is way off course for 1.50C, and the difference between 1.50C and 20C could be catastrophic.
“The message from scientists was that each half-degree counts,” said Amy Dahan, a science historian specialising in climate at France's National Centre for Scientific Research.
It was a message heard around the world. For Corinne Le Quere, president of France's High Commission for Climate Change and member of Britain's Committee on Climate Change, 2019 was “something new”. “I’ve worked on climate change for 30 years and for 29 of those, as scientists, we've worked unnoticed,” she told AFP.
The IPCC report concluded that global CO2 emissions must drop 45 percent by 2030 — and reach “net zero” by 2050 — to cap temperature rise at 1.50C. “It’s given us a clear timeline: we have 12 years to act,” said Caroline Merner, 24, a Canadian member of the Youth4Climate movement.
The UN last month said carbon emissions must decline 7.6 percent annually by 2030 to stand any chance of hitting 1.50C. Scientists meanwhile said emissions this year will instead rise 0.6 per cent. A total of 66 nations now have plans to be carbon-neutral by 2050.
Despite growing mobilisation and awareness, COP25 barely squeezed out compromises from countries over a global warming battle plan.
Younger generations appear to have woken up to the threat of climate catastrophe, but industry shows little signs of sharing their urgency. "In a sense, climate change makes us all more equal. It makes us more capable of acting together,” Alfredo Jornet, professor at the University of Oslo, said.
