Climate change can often feel like a huge problem with few actionable solutions. Just look at the facts: July was the hottest month on record. Eighteen of the last 19 years have been the warmest recorded. And the rate of CO2 increase in the atmosphere is unprecedented in the geologicrecord.

While it's true that politicians and entire countries hold many of the keys to fixing these issues, there are simple way you can help — through apps.

Your smartphone isn’t only your connection to the world — it can also be your connection to the conversation around climate change. With these four apps, awareness and action are at your fingertips.
