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.
