According to a modeling study from NASA's Jet Propulsion Laboratory and the California Institute of Technology, global climate change will modify plant communities covering almost half of Earth's land surface. The projections indicate that many plant and animal species face increasing competition for survival. Most land that's not covered by ice or desert is projected to undergo at least a 30 percent change in plant cover - meaning humans and animals will need to adapt and often relocate. "For more than 25 years, scientists have warned of the dangers of human-induced climate change," says Caltech scientist Jon Bergengren. "While warnings of melting glaciers, rising sea levels and other environmental changes are illustrative and important, ult
