Excerpt: “As I learned in my reporting last summer, (2013) in temperate or cold climates, trees and plants are adapted to wide temperature ranges and can migrate to latitudes for many miles north to stay in their ecological comfort zones. In the tropics, where most of the world’s biodiversity exists, trees and plants live in extremely narrow temperature ranges. To survive, they will need to reproduce in higher altitudes where space is far more limited and upslope soils might not be accommodating – hence the possible threat to coffee growing in the future.”

This radio report (7:17 minutes) for WUNC-North Carolina Public Radio overviews my climate change reporting in summer 2013 from the Amazon basin of Peru. It discusses the implications of upslope tree migration in the Amazon jungles as a result of warming temperatures.
The second recording (12 minutes) is of Wake Forest biologist MIles Silman and me on the afternoon news program at WUNC, The State of Things, with Frank Stasio, discussing the same topic.

Tropical plants are migrating due to climate change, but can they move fast enough?
Tropical biologists are coming to understand the impact of of global warming on our warmest climates. Given the enormous importance of tropical forests in places such as the Amazon basin of Peru, where I spent more than two weeks in July 2013, to influence weather patterns, the water cycle and carbon storage from greenhouse-gas emissions, there is much at stake. My story here on National Geographic News explains.
