Max Planck Society
"The Max Planck Society is Germany's most successful research organization. Since its establishment in 1948, no fewer than 18 Nobel laureates have emerged from the ranks of its scientists, putting it on a par with the best and most prestigious research institutions worldwide. The more than 15,000 publications each year in internationally renowned scientific journals are proof of the outstanding research work conducted at Max Planck Institutes – and many of those articles are among the most-cited publications in the relevant field."

Max Planck Institute for Meteorology
"The Max Planck Institute for Meteorology (MPI-M) is an internationally renowned institute for climate research. Its mission is to understand Earth's changing climate. Scientists at the MPI-M investigate what determines the sensitivity of the Earth system to perturbations such as the changing composition of its atmosphere, and work toward establishing the sources and limits of predictability within the Earth system. For that purpose MPI-M develops and analyses sophisticated models of the Earth system. Targeted in-situ measurements and satellite observations complement the model simulations." (Source)
The study presented in this video evaluates data from observational towers, satellite pictures and other published data to compare the impact of land-cover change and land management change on climate. The results show that land management change within the same vegetation (e.g., harvesting a formerly untouched forest) has effects on climate change that are similarly large as effects of land-cover change (e.g., changing forests into pasture). Thus, JULIA PONGRATZ explains, earth system models which are used to estimate human impact on climate should include changes in land management.
