How Major Carbon Producers Drive Sea Level Rise and Climate Injustice

Union of Concerned Scientists

Previous attribution research published by my Union of Concerned Scientists colleagues have allowed us to draw causal connections between sources of heat-trapping emissions and resulting impacts, like present day increases in atmospheric greenhouse gas concentrations, air temperatures, sea levels , ocean acidification , and wildfire burned area.
