Tapping Earth’s largest source of clean energy — its oceans. Ocean waves, tides and heat. A massive resource. Then, there’s salt gradient energy. Wherever fresh river water flows into salty seas, electricity can be generated, with zero carbon emissions.
Earth’s oceans are warming at a remarkable rate. Over ninety percent of the atmospheric heat humans have generated in the course of the past decades has been absorbed by Earth’s oceans. The consequences for oceans and atmosphere have been dire, and promise to play out over centuries, regardless of what we do.
Planet Earth is covered in water. Ninety-seven percent is in earth’s oceans. Most of the rest is frozen solid — locked up in sea ice and terrestrial ice sheets, glaciers and permafrost. Earth’s cryosphere plays a huge role in regulating climate. As our planet warms, its cryosphere is slowly melting, triggering positive feedbacks that make earth scientists worry.
A mild mid-March in Canada’s notoriously frigid prairie capital cannot be definitively pinned on global climate change. Still, for anyone willing to listen, read and watch, the writing is on the wall. Earth is warming — and fast.
Rising seas linked to global climate change pose a major threat to coastal cities around the world. Who better to turn to for nature-based flood control systems than the Dutch?

I had been pressing Marshall Islands conservationist Ben Chutaro to take me to Mili Atoll, to see the marine/nature conservancy he was setting up — but weather ended up not permitting. We went to Arno instead.
