In April 1782, just six years after the Declaration of Independence was signed, John Adams arrived in Amsterdam as the first U.S. Ambassador to The Netherlands. Three months later, a consortium of Dutch bankers provided a 5 million guilder loan (equivalent to $150 billion today) to the new republic, a clear sign of my country’s confidence in the U.S. While I can’t provide a loan, as a Dutch water engineer I can offer something else to Americans: my country’s five centuries of experience living, working, and thriving below sea level. This is surely knowledge and knowhow that the U.S. will desperately need as water levels continue to rise and countless coastal communities are threatened.
