Climate change statement highlights human influence

Abstract

A new AGU position statement on human impacts on climate states that “human activities are increasingly altering the Earth's climate.” Natural influences alone do not explain the increase in global near‐surface temperatures in the latter half of the 20th century, the statement explains.Announced at a 16 December press conference in Washington, D.C., the statement notes that human impacts include atmospheric greenhouse gases, as well as air pollution, airborne particles, and land alteration.
