The Climate Shift Index

The Climate Shift Index shows you how much global heating has influenced today's weather. Every day the Climate Shift Index map reveals where in the United States temperatures have been affected by climate change. The map reveals just how much global warming could be affecting the weather on any given day.

The colors on the Climate Shift Index map where that day's temperatures are more or less likely due to climate change. The darkest areas on the map indicate those areas where climate change has had the greatest effect on the day's weather. For example, an area shaded dark red, with a CSI score of 5, is experiencing weather which climate change and global warming has made five times more likely. In other words the local temperatures being experienced in those locations would be nearly impossible without carbon pollution creating global heating.

The Climate Shift Index is updated daily in order to show the local influence of climate change, every single day. The map provides a 3-day CSI forecast for US weather, which means you can view the CSI forecast for the current day and for the following two days.

You can learn more about the Climate Shift Index and how it is calculated on Climate Central's Introducing the Climate Shift Index.
