A pioneering research project is aiming to determine how forests in the Amazon, the Congo and elsewhere in the tropics will reacting to rising temperatures
Mid-morning in the Luquillo experimental forest in north-west Puerto Rico, and the thermometer already reads 26C. Tana Wood, an ecologist employed by the US Forest Service, pulls on a pair of heavy gloves for insulating against electrical shock.
Over two years, her team here has laid out hexagonal plots four metres across, each about the size of a backyard trampoline. Industrial-strength heaters suspended several metres above the ground from metal scaffolding on the perimeter of three plots will heat the soil and undergrowth to 4C above the forest’s ambient temperature.
