Old weather has long been one of my favorite crowd sourcing data research projects.

“Oldweather.org is where you can help improve reconstructions of past weather and climate across the world by finding and recording historical weather observations in handwritten Royal Navy ship logs.”

In this video project scientists explain how they use old weather data to reconstruct weather in the past using super sweet animations. ( thanks to Liz Stokes for sharing this one on FB!)

Enjoy.
