When it comes to our earthly survival as a human species, words are often under-powered and off-the-mark. Clearer concepts, definitions and terms are required for clarity. Here are five terms that are useful and worth remembering:

1. Planetary Boundaries
2. Earth Systems
3. Human Perturbations
4. Planetary Scale Destabilization
5. Holocene Epoch vs. Anthropogenic Epoch 

These terms all tie back to a single source – a child of World War II, only seven when his home in Amsterdam was overrun by Nazis. His father was a waiter, his mother a cook in a local hospital. He’d later recall with a shudder the Fall of 1944, the beginning of “hongerwinter” (winter of  famine) which he blamed for stunting his growth and contributing to his short stature. The event also exposed him to death for the first time, losing several classmates to starvation and frozen temperatures that winter.

There were no early signs of brilliance. He attended a technical school and prepared for a life in construction. He met a Finnish girl, Terttu when he was 25, and they settled in a small town 200 km north of Stockholm. It was his wife who recognized his potential first, pointing him toward a newspaper ad for a job as a programmer at the Stockholm University’s Meterorologic Institute (MISU). No matter that he had no experience in computer programming. They moved to Stockholm. He worked and they both took college courses. By age 30, with sponsorship from the world’s expert on acid rain and first chairman of the Intergovernmental Panel on Climate Change (Bert Bolin), he received a master’s degree in meteorology. Five years later, after focusing on stratospheric chemistry, he earned his doctorate.
