Right Whales Thrive When We Finally See Climate Change as a Symptom of Place-based Problems

My first experience with a right whale was as a college student alone on the deck of a twenty-seven-foot sailboat. Suddenly, beside me was what looked like a sandbar the length of the boat. Yet, it was alive and moving forward. Those below decks thought I was having an epileptic attack.  I had never imagined there could be an animal so big.  This was 1974 before pictures of whales underwater had been published.  The whale surfaced only once, close by, perhaps to give us a look or to be seen. Leaving a circular slick spot in the water, the whale was never seen again.  It was a right whale because of its broad back and no dorsal fin.  I was hooked while the whale swam free.

At that time, there were estimated to be 350 North Atlantic right whales. The whale population grew to more than 420 whales, and then, during the last decade and a half, the right whale population plummeted to 350 or less. Most alarming is that there may be fewer than 70 reproductive female rights whales.

The government is stepping up to address the two leading killers of whales: ship strikes and entanglements with lobster trap gear. Vessels are being mandated to slow down to eleven mph (10 knots) when whales are in the immediate vicinity, and lineless lobster trap gear is being developed.

These necessary measures will be woefully inadequate if the systemic problems are not identified and addressed. Climate change and the ocean’s declining health are symptoms of several place-based factors. Tackling more than one factor (emissions) is the best way to save the right whales and us from the impending climate calamity.

One factor is nutrient pollution, which fuels harmful algal blooms and causes ocean dead zones. Nitrogen from sewage and fertilizers is flushed off the land and into the sea. Climate change-driven weather patterns of increased rainfall are worsening the damage.  While we cannot control the rain, we can better manage stormwater.  We can slow the flow and benefit from more water in the land.

The right whale’s food pyramid is short: whale, zooplankton, phytoplankton, and nutrients. Phytoplankton in the Gulf of Maine is 65% less productive than twenty-five years ago. Since 1970, phytoplankton populations have fallen by over 50%.

In 1970, the herbicide glyphosate was discovered and sold in commercial formulations such as Roundup. In 1996, Roundup manufacturer Monsanto created genetically engineered seeds that can withstand higher amounts of the herbicide, and the use of glyphosate increased tenfold. The chronology of the rise of glyphosates and the loss of phytoplankton lines up too closely to be coincidental.

Glyphosate is an enzyme inhibitor that causes cell death, damages cellular structures and disrupts biochemical processes, including respiration and photosynthesis. As a result, it is the most widespread and effective herbicide. In addition to agricultural and residential uses, glyphosate is used to clear invasive plants, powerline rights of way, transportation routes, and industrial yards. It has even been found toxic to particular biota, including algae, fungi, and bacteria. (Bacteria are a poorly understood yet vital part of ocean ecosystems.) Studies have shown commercial formulations like Roundup may be more harmful than glyphosate.

The third mitigating factor degrading the right whale’s habitat is warming water.  Fearing an unstoppable rise of worsening climate change, many have forgotten that one cannot heat a cup of coffee with a hair dryer. To warm the coffee, the cup is placed on a hot plate.  With the loss of vegetation and soils, along with dramatic increases in impervious surfaces and urbanization, more hot plates are warming more water reaching the sea than ever before.

What’s happening on the land far from the sea harms the ocean ecosystems that right whale lives depend on. We have passed the tipping point where our collective actions have turned a growing right whale population into one in decline. But the good news is that we can be part of the solution.

We may urge the federal government to create the Right Whale National Marine Sanctuary, which would bring together all users and interest groups to better manage the sanctuary’s waters, surrounding ocean waters, and all the lands in the watersheds. Right whales are magnificent iconic figures. Our concern for their welfare inspires more responsible actions, such as using less pollutants and practicing better stewardship of our lands. When we create more vegetation and soils holding more water, resulting in more plant growth and transpiration, it cools the microclimates around us and the waters flowing into the sea.

The Right Whale National Marine Sanctuary will only happen if all user and interest groups collaborate to better manage it. Instead of more regulations, we must better understand how our actions may harm or help the right whale population. Ecosystem management must be adaptive, comprehensive and robust, inspiring everyone to participate.

When savvy people work in concert with one another, the North Atlantic right whales will thrive.
