Past the wrack line

Whenever I pass the wrack-line at a beach I know I’m out of my depth. At least metaphorically. The line is strewn with a kind of life that I know almost nothing about. A whole hidden world has been reaped of it’s dead and dying creatures and deposited by the cleansing tide along this meandering line on the beach. What are these long stems that I see? Is it kelp? The stem would be called the stipe then, and the round green things could be gas bladders. They are green, full of chlorophyll. They must be among the places where photosynthesis happens. Everything is turning black quickly in the air; it is like making sense of a garden from a compost pit. The black ribbons wrapped around the stipe were probably the photosynthetic blades. I have a camera that can enter the water without damage, but I didn’t prepare for a beach when I got into the car.

I step across the wrack line to watch the incoming tide. It’s a miracle that it hasn’t deposited more plastic on the beach. But as always I’m enchanted by the deep boom of the surf. The Bay of Bengal is one of the most restless seas that I know, a nursery for deadly hurricanes. Even on this rainy day, many of us are cramped into a small part of the beach, although it extends for thirty-odd kilometers around here. The tides have been eating the land here, and large parts of it are not safe. A warming earth has extended the season of the monsoon, even as the waters rise. A hotter earth will be a wetter earth. Water vapour is a greenhouse gas, even more than CO2. Are we at the beginning of a runaway hot house?
