The U.S. National Climate Assessment and the Intergovernmental Panel on Climate Change
(IPCC) show that reducing global anthropogenic greenhouse gas (GHG) emissions to net-zero by
mid-century will prevent the most severe damages to human health, ecosystems, and infrastructure. These climate-driven damages include deaths caused by: heat waves; loss of forests, homes, and infrastructure from increasing wildfires; flooding and extreme weather
events; property loss; damage to roads, bridges, public transit systems and the energy system;
inundation of coastal areas by sea level rise and storm surges; droughts; damage to crops; and
other harms to the ecosystems that sustain people.
