I was honored to meet Her Majesty Queen Maxima, T.R.H. Crown Prince Frederik, and Crown Princess Mary. Both Her Majesty Queen Maxima and T.R.H. Crown Princess Mary received a copy of my book, “Atmosphere, CO2 on my mind”, and I hope they will enjoy reading it. Seldomly have I been so nervous about meeting a group of people as last week. Fortunately, it turned out that the royals were well informed and very interested in sustainability and climate change.
