The projections on this page describe a future that we still have a chance to avoid. To keep average global warming below 1.5ºC—the goal agreed on in the 2015 Paris Climate Accords—we need to act rapidly to drastically reduce greenhouse gas emissions.
The risks presented on this page reflect modeled averages for Corona, CA under one projected emissions scenario and can vary for individual properties. To find out more, check a specific address and request a report describing risks to your property and in your area.
The latest Intergovernmental Panel on Climate Change report states: “If global emissions continue at current rates, the remaining carbon budget for keeping warming to 1.5ºC will likely be exhausted before 2030.” This remaining carbon budget is about the same amount as total global emissions 2010-2019.
