Observed and projected climate data analysis in R. What are the expected changes in climatic conditions?

Intergovernmental Panel on Climate Change (IPCC) Assessment published observed and projected data on climate with a high temporal coverage. The data consists of various weather and climate elements including temperature, precipitation, humidity, air pressure, etc. In this work, I will be analysing the various datasets to show current and future scenarios using R programming. The data is available at https://worldclim.org/ and https://esgf-node.llnl.gov/projects/cmip5/ (CMIP5 models). Currently I am working on the following:

Based on the data, Kenya and the world at large is expected to be hotter by 2-3 degrees celsius by the year 2050.
