Current climate data, and projections how climate may change in the (near) future, are important for various reasons. For example, such data can be used to predict how habitat suitability for different animal and plant species or agricultural productivity changes over time.
Thus, in this post, I am showing how to get data on recent and projected climate directly into R, crop the obtained object to the area of interest (here: South America), and then calculate and illustrate the projected change.
