The minimum expected, or inevitable, climate change scenarios for 2050 produce fewer projected extinctions (18% averaging across the different methods) than mid-range projections (24%), and about half those predicted under maximum expected climate change (35%). Therefore, 15-20% of all land species could be saved from extinction if the minimum scenario of climate warming occurs.

Scientists studied six regions around the world representing 20 percent of the planet's land area and projected the future distributions of 1,103 animal and plant species. Three different climate change scenarios were considered – minimal, mid-range and maximum, as was the ability of some species to successfully "disperse," or move to a different area, thus preventing climate change-induced extinction. The study used computer models to simulate the ways species' ranges are expected to move in response to changing temperatures and climate. It represents the largest collaboration of scientists to ever study this problem.

[O]ne of thirteen people on Earth actually owns a car. Consider this; 92 percent of the world's people do not own cars--and the 8 percent who do are directly responsible for climate change and the alarming collapse of biodiversity on planet Earth.
