Santa’s Revenge

Santa's Revenge

Santa’s Revenge is the theory that persistent weather patterns in mid-latitude areas, such as this extraordinarily long, harsh, record breaking snowy, and freezing winter that we are experiencing in Southern Ontario, is a result of climate change warming the Arctic.

The picture above shows me on February 26th, in downtown Toronto beside Lake Ontario braving the -16 degrees Celsius weather mixed with extreme winds to make it feel like negative 1 billion (an exaggeration due to annoyance). In fact, it was so cold that the Great Lakes were more frozen than any other time in the past 35 years (92.2 percent ice coverage).

An article has now been published which gives new evidence to suggest that the link between the Arctic getting warmer, and the mid-latitudes experiencing persistent weather. This theory has been debated time and time again, but the fact is that it has extreme implications for severe weather occurrences, food security, and water use in the northern hemisphere that would have large economic impacts.

Here are a couple of quotes from the article:

-“It’s starting to get harder to say that something isn’t happening”

-“Events like the extended cold spell… are very consistent with the kind of pattern we expect to see related to the Arctic warming so fast.”

-“Potential to drastically affect international food supplies and prices”

-“We produce the bulk of our crops at that mid-latitude area”

Climate change is extremely worrisome. With 7 billion people in the world we cannot afford to experience food security issues as many people will be left without access to sufficient, safe and nutritious food. An increase in severe weather occurrences will cause more damages, more serious social disruption and more loss of human life. The economic impacts of climate change will leave many economies around the world in disarray as they try to cope with its negative effects.

“The real question is whether we can adapt and change faster than the climate.”

Apex Predators

One species of animal can greatly influence an entire ecosystem. This cascading effect that can occur can even change the geography of an area, showing the extent of influence an animal can hold in an ecosystem.

A video has recently gone viral which shows how the introduction of wolves into an ecosystem actually changed a river’s path. This video is entitled How Wolves Change Rivers. In this video a man describes how wolves were introduced into Yellowstone National Park in the United States, and, through this reintroduction of a species into an ecosystem, how the wolves led to an increase in vegetation, and the eventual change in course of a river. Although many people are aware that wolves kill other animals, most are unaware that they can give life. Yellowstone Park was overpopulated with deer and these deer had grazed all of the vegetation, leaving bare flat lands. In this case study the wolves ate the dear in the park, which led to less deer, and made the remaining deer avoid the wolf populated areas. These avoided areas then experienced a rapid increase in vegetation growth, creating forests in places which once only held grass. Due to the increase in trees there was an increase in beavers because, well, beavers like trees. These beavers are ecosystem engineers and they in turn built dams which provided shelter for countless other species. The wolves also killed coyotes and this meant that there was an increase in mice, rabbits, hawks, weasels, foxes, badgers, ravens, and bald eagles. Now not only was there a massive increase in species throughout the park, but the river running through the park experienced less erosion, the channels narrowed, and pools formed due to the increase in vegetation and the stabilization of the river banks that this vegetation provided. The river itself changed. This process is known as a tropic cascade.

The concerning issue about this case study is the fact that wolves are only one apex predator in the world: lions in Africa, tigers in Asia. Sharks, bears, and wild dogs are example of species at the top of their particular food chains, stabilizing the ecosystem and species they live and prey on, and influencing the health of plants and animals all the way to the bottom of the tropic ladder.

The truly disturbing part is that a majority of these apex predators are facing a decline in population numbers, potentially endangering the ecosystems where they reside.

This calls for change. It’s time for us, as humans, to change our overall perception of predators. We cannot condone the mass culling of sharks as has recently been approved in Western Australia. Stop the poaching of Tigers in Asia. No more habitat destruction in Sub Saharan Africa that decimates lion populations.

Human/wildlife conflict is going to occur as population growth happens around the world. Humans need to change and start living with wildlife if we want to protect the beautiful, useful, and essential ecosystems around the world.
