Major negative effects of climate change are here now and they're only getting worse, as shown by recent reports from the United Nation's Intergovernmental Panel On Climate Change (IPCC) and the White House among others.
The greenhouse gas emissions that drive warming "now substantially exceed the highest concentrations recorded in ice cores during the past 800,000 years," the IPCC said. Atmospheric carbon dioxide levels, which primarily come from the burning of fossil fuels, have risen 40% since pre-industrial times.
We've gathered some notable effects of climate change below.
Unless otherwise noted, each effect assumes a temperature rise of 2 degrees Celsius (3.6 F) by 2100, a number the IPCC has suggested we are "more likely than not" to exceed, and a sea level rise of 0.5 meters (1.5 feet) by 2100, about the average of all the IPCC's most recent climate scenarios. This is a conservative estimate as other studies have suggested that sea level rise will be much greater if climate change continues unmitigated.
