I recently discovered tikz and I fell in love with it! However, I am having some annoying issues when I try to include a tikz mindmap in beamer. Problem is that I can't manage to have the mindmap scaled to the beamer slide size. Below is my code, see attached image for my output. Thanks!

Along this site it is possible to find a lot of questions and answers related to scaling tikzpictures. Here I add some references:

In particular:

and

Starting from you example, it was sufficient to properly declare the distances of the various mindmap's levels by means of:

\tikzset{level 1 concept/.append style={font=\sf, sibling angle=90,level distance = 27mm}}
\tikzset{level 2 concept/.append style={font=\sf, sibling angle=45,level distance = 17mm}}
\tikzset{every node/.append style={scale=0.6}}

and to change the position of the concepts Atmospheric Exchanges and Surface Energy: you gave them by hand, but they actually were placed too much far.

Notice also that I removed yours

\begin{figure}[h]
\makebox[\textwidth][c]{

not really needed.

The complete code:

\documentclass[8pt,T]{beamer}  
\usepackage{comment} 
\usepackage{graphicx}
\usepackage{tikz}
\usetikzlibrary{mindmap,trees, backgrounds}

\tikzset{level 1 concept/.append style={font=\sf, sibling angle=90,level distance = 27mm}}
\tikzset{level 2 concept/.append style={font=\sf, sibling angle=45,level distance = 17mm}}
\tikzset{every node/.append style={scale=0.6}}
