GPS upgrade could cut airline fuel and delays nationwide
The switch to a satellite based NextGen GPS network could trim fuel use and delays, saving airlines billions. FAA projections show potential annual fuel savings of over 10 billion dollars by 2025 and major efficiency gains, though funding and rollout delays push full implementation into the early 2020s. Southwest Airlines plans a 175 million dollar GPS retrofit for 500 planes, enabling quicker landings and faster ground times.

Climate change may harm tropical species
Scientists led by Robert K. Colwell in Costa Rica warn in Science that tropical plants and animals face serious risk from warming. A projected 5.8 F rise over a century could threaten over half of 1,902 lowland tropical species, with some thriving weeds likely to endure as others fade.
