How did humans get to the brink of crashing climate? A long push for progress and energy to fuel it

Amidst record-high temperaturesdelugesdroughts and wildfires, leaders are convening for another round of United Nations climate talks later this month that seek to curb the centuries-long trend of humans spewing ever more greenhouse gases into the atmosphere.

 

For hundreds of years, people have shaped the world around them for their benefit: They drained lakes to protect infrastructure, wealth and people. They dug up billions of tons of coal, and then oil and gas, to fuel empires and economies. The allure of exploiting nature and burning fossil fuels as a path to prosperity hopped from nation to nation, each eager to secure their own energy.

People who claimed the power to control nature and the energy resources around them saw the environment as a tool to be used for progress, historians say. Over hundreds of years, that impulse has remade the planet’s climate, too — and brought its inhabitants to the brink of catastrophe.

CONTROLLING THE ENVIRONMENT

Mexico City traces its roots to a settlement centuries ago on islands in the midst of Lake Texcoco. These days, most of the lake is gone, drained long ago to make room for the building and growth that today has more than 22 million people sprawling toward the edges of the Valley of Mexico.

Getting water in the arid valley — a need that has spiked as droughts have worsened — relies on pumping from deep underground. The toll of centuries of such pumping can be seen in curbs that crumble and structures that tilt atop the resulting subsidence, with some areas sinking around 30 centimeters (11.8 inches) a year. At the same time, neighborhoods are at increased risk of severe flooding because of climate change-fueled extreme rain events and drainage systems that are less effective because of the subsidence.

“Nature doesn’t create these huge problems,” said Luis Zambrano, professor of ecology at the National University Autónoma of Mexico. “Nature behaves as nature … we are increasing our vulnerability by allowing the city to sink by pumping as much water as we possibly can from the aquifer.”

Mexico City is just one example of people and empires altering their natural environments in ways they believe will benefit themselves and the land. Elsewhere, huge swathes of land have been deforested for agriculture or livestock grazing, or degraded and contaminated by quarrying and mining for metals and minerals. Tapping nature for its resources drove progress and productivity for some, but it’s also been a major driver of emissions and environmental degradation.

Anya Zilberstein, a historian of climate science at Concordia University in Montreal, highlighted the example of Europeans colonizing the Americas in the 16th and 17th centuries as an early catalyst for modern-day climate and environmental crises.

“They bring with them this idea that conquest and then the development of the cultivation of landscapes, like taking down trees, opening up lands to European style agriculture, that the draining of swamps … will also change the climate, usually for the better,” Zilberstein said.

The Aztecs built Tenochtitlán — what became Mexico City — on the lake’s islands and chinampas — small, artificial fields. When the city later fell under Spain’s rule, it was seen as the “most gorgeous jewel in the Spanish empire,” with ornate palaces and commercial hubs, said Vera S. Candiani, a historian of Latin America at Princeton.

Catastrophic flooding in the mid-16th century led the Spanish to pursue drainage projects that aimed to keep the city dry and prosperous, and stretched on for three centuries, Candiani said.

But not everyone benefited equally.

Candiani said that capital-owning elites got technicians, engineers and other professionals to implement a system of extracting resources and labor from the countryside to benefit the city in colonial Mexico, and more broadly from the colonies for the gain of the home country. Rural populations, who contributed the most to the project through coerced labor, didn’t benefit.

Jan Golinski, a professor of history at the University of New Hampshire, said Europeans of the time thought that their changes — cutting down forests, draining swamps, plowing land — would change the climate as well, to something closer to their homelands. He said they saw this engineering as positive.

“They believed that their society was making progress, that it was gaining greater control over nature, that they were becoming more civilized and were civilizing the environment around them,” Golinski said.
