In total, 377 climate datasets reside in the US government open data initiative. In order to meet the challenge of a changing climate, the US Climate Resiliency toolkit simplifies the process of building resilient communities. For example, you can access environmental vulnerabilities by obtaining climate projections to the year 2100. By searching your zip code in the Climate Explorer, you can understand your risk and better protect your investments further down the road.

Massive collection of Earth science data. It’s through the NASA Earth Observatory where anyone can track 16 climate factors such as aerosols, temperature and carbon all the way back to 1999. The best part is how NASA makes it easily understandable for the public to consume. If you’re looking for another flavor to study our planet from space, check out NASA Earth Observations (NEOs).

There’s been an enormous push to track our changing climate in Europe. After all, it’s the Copernicus Mission that dedicated an entire fleet of satellites to measuring our climate from space. The European Space Agency Climate Change Initiative (CCI) leverages 40 years of satellite observations, by merging past mission data.
