Simulate climate change on your iPhone or iPad!

Climate Pathways is Climate Interactive's real-time climate change simulator for iOS devices. With a trace of your finger, draw annual global emissions from now through 2050. Climate Pathways tells you INSTANTLY what the average global temperature will be based on what your finger's motion! All on a mobile device. Cool, huh?

In Auto Mode, tap the screen to indicate the peak year/amount of global emissions. Again, Climate Pathways will INSTANTLY calculate what emissions would have to be to stay below 2 degrees Celsius in 2100, the internationally agreed upon goal. The annual rate of emissions decline is also displayed for you on the screen.

Does what it says on the tin

It's fun and cool to be able to try different emissions scenarios on my iPad. I especially look forward to showing this to kids.
