Unaddressed, climate change will entail a potentially catastrophic human and economic toll, but it’s not too late to change course.
Global temperatures have increased by about 1°C since the pre-industrial era because of heat-trapping green-house gases accumulating in the atmosphere. Unless strong action is taken to curb emissions of these gases, global temperatures could increase by an additional 2–5°C by the end of this century. Keeping temperatures to levels deemed safe by scientists requires bringing net carbon emissions to zero on net globally by mid-century.
“The human influence on the climate system is clear and is evident from the increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing, observed warming, and understanding of the climate system.” —Intergovernmental Panel on Climate Change, Fifth Assessment Report
Fossil fuel prices are likely to stay “low for long.” Notwithstanding important recent progress in developing renewable fuel sources, low fossil fuel prices could discourage further innovation in and adoption of cleaner […]
