As climate change tightens its grip across the globe, a growing body of scientific research is revealing just how far-reaching the consequences of Amazon deforestation may be, stretching as far as the Sierra Nevada snowpack and the ski slopes of the American West. Multiple peer-reviewed climate simulation studies now point to a startling link: large-scale destruction of the Amazon rainforest could reduce snowfall in western North America by up to 50% and rainfall in the Pacific Northwest by as much as 20%. That’s because the Amazon is also a critical component of the planet’s weather system that serves as a vast moisture engine that feeds atmospheric rivers of rain and snow thousands of miles away.
One example: atmospheric models published in the Journal of Climate depict that eliminating Amazon forest cover would generate a dry air mass that sweeps northwest, triggering drier winters in the U.S., especially over western American snowpack zones like the Sierra Nevada or Rocky Mountains. According to the Princeton University American Meteorological Society Journals, that connection illuminates why protecting forests on the other side of the globe can directly influence snow in places like Tahoe or Aspen, with that connection no longer being theoretical but now measurable.
At the center of the fight to protect the forest is American Paul Rosolie, a veteran conservationist and founder of Junglekeepers, a nonprofit that trains and funds local rangers to patrol and defend some of the most threatened regions of the Peruvian Amazon. In theory, his work not only protects the rainforest, but in turn, North American winters. Rosolie has spent more than 20 years living in the rainforest. Today, he’s working to raise awareness about what’s at stake if the Amazon continues to fall.
“The contrast between ancient forest and the hellscape of the destruction. This is the conquest of the biosphere,” Rosolie said in a recent video campaign. “But we have a plan. We just need help to make it happen.”

Junglekeepers’ work is focused on the Madre de Dios region, an area known for its staggering biodiversity and intensifying deforestation. By supporting local forest guardians, the organization protects over 50,000 acres of intact jungle, helping to preserve the ecological function of a region that drives rainfall cycles across the Americas.
The science behind these connections comes down to how rainforests interact with the atmosphere. Trees in the Amazon release vast amounts of water vapor, fueling massive weather systems that travel west and north. When those trees are removed, the atmosphere becomes drier, air circulation shifts, and major climate systems like the jet stream and Rossby waves become destabilized.
This doesn’t just mean less rain in the tropics. It means shallower snowpacks in California, shorter ski seasons in Colorado, and depleted reservoirs that millions depend on for drinking water and agriculture. While the climate models describe extreme scenarios with complete or near-total loss of the Amazon canopy, the warnings are clear: protecting the forest today could help prevent climate instability tomorrow.
For snow lovers, they may feel far removed. But they have a role to play. Because whether you ski in Tahoe, farm on a ranch, or drink water from the Colorado River, the fate of the Amazon affects your life. This isn’t just about saving the rainforest—it’s about protecting what happens in your own backyard.
To support forest protection efforts, Rosolie urges people to donate directly to frontline organizations like Junglekeepers, share educational content, and stay engaged with conservation policy. His team’s recent short film, The Mission, outlines the scale of the crisis and what can still be done. The Amazon is at a crossroads, and either we lose it forever to development and deforestation—along with our powder-filled winters—or we create a lasting legacy that protects it.
“It’s not too late to fix this,” Rosolie said. “But time is running out.”
