far greater problems before
and can do so again...
Young people across the world are terrified of climate change, according to a forthcoming Lancet study (Young People's Voices on Climate Anxiety, Government Betrayal and Moral Injury - A Global Phenomenon).
More than 45% of people 16 to 25 in the 10 countries surveyed are so worried that it affects their daily life and functioning.
But while climate change is a problem, panic is unwarranted.
The data shows that humanity has overcome much larger threats over the past century.
In 1900, if humanity had gotten rid of air pollution - mostly indoor pollution caused by smoky fuels like wood and dung - the benefit would have been equivalent to global gross domestic product rising 23%.
To a young audience, that might look like an insufficient measure of well-being, but higher GDP means better health, lower mortality, greater access to education, and in general a better standard of living.
By 2050, the problem of air pollution will be mostly solved.
And that's only one of the many issues humanity has shorn down over the last 100 years, according to data 21 top economists and I gathered.
The challenge climate change poses, both to the environment and society, looks rather small compared to those humanity has already met.
Noble Prize-winning climate economist William Nordhaus has shown that a 6.3-degree Fahrenheit rise (14.3-degree Celsius) in world temperatures by 2100 - which is probable if policymakers do little to stop climate change - would cost only 2.8% of global GDP a year.
The United Nations' latest estimate puts it even lower at 2.6% of GDP for a 6.6-degree Fahrenheit increase.
Moreover, the U.N. expects the average person to be 450% as rich in 2100 as today, absent the cost of climate change.
Following current temperature projections, global warming would knock that down to only 434% as rich. That's a problem, but it isn't the end of the world.
That's what saved humanity from much greater dangers in the past and what will help us now.
