So when did mice start to worry about climate change? It was in 2007, when my husband and I were having dinner in Amsterdam with an ex-student of his, Surya Green (herself the author of a book called "The Call of the Sun: A woman's journey to the heart of wisdom.") I gave her a quick summary of the plot of my book, which at that time ended with mice making the Thumbtop computers they need. Surya asked what happens next–what would mice do with their new power? And the answer was obvious. If any species can fix climate change–and do it soon–it’s mice. Right?
