La production agricole a fait un bond phénoménal en 10 ans, mais la FAO déplore que les investissements se concentrent sur les agrocarburants et les achats de terres dans les pays du sud, au détriment des petits producteurs.

This is not a complete data set, but the video still shows the striking connection between CO2 emissions and the historical geography of industrialization. Via Seth Dixon, Lauren Moss, Digital Sustainability

What data did you use? Historical, proxy or climate station? From 1800-1920's, was CO2 derived from historical observations, ice cores? Pre- to post-war had the maximum extent of climate stations, which captured CO2 (broadens extent). Throughout the mid-50's to present, due to lack of funding, climate stations plummeted from over 400 stations worldwide to approximately 80. When we reconstitute all these different types of data, we often get what geographer's call the modifiable areal unit problem... Furthermore, this is compounded not only by extent but also by timeline/data availability.

I'd love to take credit for this, but I didn't create this video, but am simply sharing a resource that I found online with the broader community. Follow the YouTube link to see info about the creator there (Cuagau1).

Frightening and guilt inducing. The US and Europe the biggest historical violators, plus living in the northeastern part of the country which shows the highest concentrations.
