Scientists to take to the streets in global march for truth.
By Mark Lynas
March for Science on 22 April will see scientists and supporters at more than 500 locations stand up for evidence-based thinking.
What began as a small Facebook group in the US capital, Washington DC has spiralled into a global phenomenon that will now see marches and other events in more than 500 locations around the world, from Seattle to Seoul.
It is great news that so many people are prepared to stand up and defend the need for evidence-based thinking and the scientific method.
But it is also a sad comment on our times that a March for Science is needed at all.
Post-truth populism has infected democracies around the world, scientific objectivity is under threat from multiple sources and there seems a real danger of falling into a modern dystopian dark age.
It is clear that the old days of scientists staying in the lab, publishing papers in scholarly journals, and otherwise letting the facts speak for themselves are over.
As the Harvard science historian Naomi Oreskes reminds us: “The facts don’t speak for themselves because we live in a world where so many people are trying to silence facts.”
In her book, Merchants of Doubt, Oreskes wrote about these efforts from the tobacco industry onwards; science denialist attempts that are paralleled in today’s climate sceptic, anti-vaccine and anti-GMO movements.
The fact that 97% of the peer-reviewed literature on climate change supports the consensus that most of global warming is human-induced is dismissed as mere elitism.
But as Dr Sarah Evanega, director of the Alliance for Science at Cornell, writes: “The values we defend are those of the Enlightenment, not the establishment.”
Expertise is real, and we reject it at our peril.
Perhaps the most inspiring aspect of the March for Science, and what may prove to be its most enduring legacy, is its truly global nature.
Science is not western; it is everywhere and for everyone.
I have worked with Alliance for Science colleagues to help get marches off the ground in Bangladesh, Nigeria, Uganda, Venezuela, Chile and other places.
In between long Skype calls about logistics, fundraising, and media outreach I watched the lights flash on as the number of marches on the global map kept on increasing.
It was like watching the world light up with knowledge.
Bangladesh March for Science’s lead organiser Arif Hossain says: “I am marching to let the world know that we are united for science in Bangladesh.
We have 160 million people to feed in the changed climate, and together we will make a better day with science and innovation.”
Although the issues of most concern vary in different locations, appreciation of the need for science is global. As Nkechi Isaac, an organiser of the March for Science in Abuja, Nigeria, says: “Science is revolutionary.
It holds the key to constant development and improvement for addressing climate change, food shortage and challenges in medicine. Science holds the solution to our food security.”
Nigerians can testify to the tragic effects of anti-science activism. Efforts to eradicate polio in the country were held up for years because of conspiracy theories spread by those suspicious of modern medicine and vaccines. People die when science is denied.
So here’s what we will be marching for.
It’s time to enter the post-post-truth era.
And there is no time to lose.
