Whales Can Change Global Warming

Updated on November 20, 2017

How Whales Change Climate

Humans have wiped out 90 percent of the whales in the oceans. As the gentle giants disappeared so did their poop. Said differently, the oceans process 90% less whale feces today than they did in the 1300s when whales were numerous. This was about the time when the little ice age started. This period of bitter cold began to fade away just before the start of the 19th Century when the number of whales killed started to drop. The killing still continued from mechanical-powered factory ships with explosive harpoons and Earth got warmer. The whales almost disappeared in the 1960s at about the same time scientists began to realize that our planet was getting hotter and hotter. Is there a connection between reduced whale poo and global warming?


The first success of the environmental movements of the 1960s was to save the whales. Now that whales are making a comeback, they might be about to save us with their poo. A new scientific report from the University of Vermont, which gathers together several decades of research, shows that the great whales are now recovering due to the 1983 ban on whaling. This study also shows that they contribute to massive carbon sinks (stored CO2) via their prodigious production of feces.



Not only do the nutrients in whale poo feed other organisms, from phytoplankton upwards – and thereby absorb the carbon we humans are pumping into the atmosphere – even in death the sinking bodies of these massive animals create new resources on the seabed, where entire species exist solely to graze on rotting whale carcasses. There's an additional and direct benefit for humans, too. Contrary to the suspicions of fishermen that whales take their catch, cetacean recovery could "lead to higher rates of productivity in locations where whales aggregate to feed and give birth". Their fertilizing feces encourage phytoplankton which in turn encourages healthier fisheries.

There is also a long range connection between whales and climate warming and cooling. Scientists have recently found evidence that the Earth has gone through 50 climate changes in the last 2.7 million years ago. The ice cover at both poles greatly expanded and retreated during these worldwide changes.


The recent cold period was a mini ice age in which many of our ancestors starved due to crop failure. There was not enough food in the fields to feed the rats so they moved into the towns to live with the people, spreading the black plague, killing even more poorly nourished humans with weak immune systems.

Humans will not do too well during next ice age. What about the whales? Maybe they will starve too? We know one thing for sure: The increase in sea ice near the poles blocks the sun's rays and stops the growth of zooplankton. On the other hand, the lack of sea ice near the polar caps, like we have now, brings about an extraordinarily favorable growing conditions for zooplankton – which is a good thing for the baleen whales that eat them, says Patrick Miller at the University of St Andrews in the UK.

Lots more sunlight can reach below the surface of ice-free oceans, fueling blooms of phytoplankton and zooplankton that the whales graze on. Other nutrient levels in reach of the whales also increase. Wind blowing across the now open sea surface causes water to mix,” says Miller. “This brings nutrients up from depth.”

This allows great whale populations to explode and so does whale poop, which in turn serves to nourish the zooplankton.

Bottom line is that all we need to do to save our planet from global warming is save our whales. If we don't, we are headed into an ice age that will kill our food crops and cause worldwide starvation.

Many scientists that study solar cycles say we are entering a new solar minimum (one of about 6 different solar cycles). I tend to believe them far more than I believe non-profit groups that try to rile the public emotions as a way to increase their donations. Most non-profits are not non-profits as far as the big bosses are concerned. Ninety percent of their donations go to pay advertising cost and huge salaries for the heads of these groups. For example, the International Union for Conservation of Nature (IUCN) just put out a report saying warming of the ocean is the greatest threat humans face. They want you to send them money so they can spread more nonsense and pay themselves even larger salaries.

My group, the Deafwhale Society, has never accepted money from anyone in the 40+ years that we have researched whales. We are not a non-profit group because we are too embarrassed by other non-profits that promote fabrications just to con the public into sending them money!

      Hello, very interesting. Do you have some numbers showing, potentially, what proportion of anthropogenic carbon dioxide would be turned into whale feces if whales recovered their 1300s population?
