Abstract
Climate has varied on geological timescales, and ecological systems have responded. Atmospheric CO2 has increased 36% and methane ~160% since the beginning of the Industrial Revolution (~1750), resulting in the globe warming ~0.85°C. Species are responding by rearranging their ranges. The increase of atmospheric CO2 is causing oceans to become more acidic, decreasing the pH from 8.25 in 1750 to 8.15. This change is already affecting calcium-using species. The Intergovernmental Panel on Climate Change (2007a) projected that by 2100, the planet could warm between 1.1 and 6.4°C or higher above 1990s levels.
