They’re angry at their elders, and they’re not taking it sitting down.
Students worldwide are planning to skip class Friday and take to the streets to protest their governments’ failure to take sufficient action against global warming.
The coordinated ‘school strike’ was inspired by 16-year-old Swedish activist Greta Thunberg, who began holding solitary demonstrations outside the Swedish parliament last year.
Since then, the weekly protests have snowballed from a handful of cities to hundreds, driven by social media-savvy students and dramatic headlines about the impact of climate change.
Thunberg, who was recently nominated for the Nobel Peace Prize, was cheered for her blunt message to leaders at the World Economic Forum in Switzerland this year, when she told them: “I want you to panic. I want you to feel the fear I feel every day.”
Protests in 100 countries
Friday’s rallies are expected to be one of the biggest international actions yet. A website coordinating the protests lists events in more than 100 countries, from New Zealand to the United States.
Some politicians have criticized the students, suggesting they should be spending their time in school, not on the streets.
“One can’t expect children and young people to see all of the global connections, what’s technically reasonable and economically possible,” said the head of Germany’s pro-business Free Democratic Party, Christian Lindner. “That’s a matter for professionals.”
But scientists have backed the protests, with thousands signing petitions in support of the students in Britain, Finland and Germany.
“We are the professionals and we’re saying the young generation is right,” said Volker Quaschning, a professor of engineering at Berlin’s University of Applied Sciences.
“We should be incredibly grateful and appreciative of their bravery,” said Quaschning, one of more than 14,000 German-speaking scientists to sign a letter of support this week. “Because in a sense, it’s incredibly brave not to go to school for once.”
Decades of warning
Scientists have warned for decades that current levels of greenhouse gas emissions are unsustainable, so far with little effect. In 2015, world leaders agreed in Paris to a goal of keeping the Earth’s global temperature rise by the end of the century well below 2 degrees Celsius (3.6 degrees Fahrenheit).
Yet at present, the world is on track for an increase of 4 degrees Celsius, which experts say would have far-reaching consequences for life on the planet.
“As a doctor, I can say it makes a big difference whether you’ve got a fever of 41 degrees Celsius (105.8 Fahrenheit) or 43 C (109.4 F),” said Eckart von Hirschhausen, a German scientist who signed the call supporting striking students. “One of those is compatible with life, the other isn’t.”
Policies don’t go far enough
German Chancellor Angela Merkel and French President Emmanuel Macron have publicly welcomed the student protests, even as their policies have been criticized as too limited by environmental activists.
In France, activist groups launched legal action this week for failing to do enough to fight climate change, citing a similar successful effort in the Netherlands .
In Germany, environmental groups and experts have attacked government plans to continue using coal and natural gas for decades to come. Activists say that countries like Germany should fully “decarbonize” by 2040, giving less-advanced nations a bit more time to wean themselves off fossil fuels while still meeting the Paris goal globally.
Other changes needed to curb greenhouse gas emissions include ramping up renewable energy production, reigning in over-consumption culture now spreading beyond the industrialized West and changing diets, experts say.
“The fight against climate change is going to be uncomfortable, in parts, and we need to have a societywide discussion about this,” said Quaschning.
That conversation is likely to get louder, with several U.S. presidential hopefuls planning to campaign on climate change.
Ozone-depleting substances caused half of Arctic warming and sea ice loss from 1955 to 2005, causing about a third of all global warming during that period, reveals a significant study.
A scientific paper published in 1985 was the first to report a burgeoning hole in Earth’s stratospheric ozone over Antarctica.
The discovery left scientists into a huddle to determine the cause which happened to be ozone-depleting substances – long-lived artificial halogen compounds entirely manmade and popularly used as refrigerants, solvents and propellants.
The new study from researchers at Columbia University and published in the journal Nature Climate Change examined the greenhouse warming effects of ozone-depleting substances (ODS).
It found that the ozone-depleting substances acted as a strong supplement to carbon dioxide, the most pervasive greenhouse gas. “We showed that ODS have affected the Arctic climate in a substantial way,” said researcher Michael Previdi from Lamont-Doherty Earth Observatory.
The scientists reached their conclusion using two very different climate models that are widely employed by the scientific community, both developed at the US National Center for Atmospheric Research. The results highlight the importance of the Montreal Protocol, which has been signed by nearly 200 countries.
“Climate mitigation is in action as we speak because these substances are decreasing in the atmosphere, thanks to the Montreal Protocol,” said Lorenzo Polvani, lead author of the study. “In the coming decades, they will contribute less and less to global warming. It’s a good-news story”.
In the 1980s, a hole in Earth’s stratospheric ozone layer, which filters much of the harmful ultraviolet radiation from the sun, was discovered over Antarctica. Scientists quickly attributed it to ODS. The world sprang into action, finalizing a global agreement to phase out ODS.
The Montreal Protocol was signed in 1987 and entered into force in 1989. Due to the swift international reaction, atmospheric concentrations of most ODS peaked in the late 20th century and have been declining since.
However, for at least 50 years, the climate impacts of ODS were extensive, revealed the new study. (IANS)
