Gerbils and the Black Plague

 In the years 535-536, a sudden change in climate occurred throughout the known world.  The sun turned blue, and a haze filtered what little light there was.  Temperatures dropped, crops failed, and people died.  The theory is that a volcano erupted somewhere in the world and caused a temporary change in climate.

In a little corner of Africa, gerbils who hosted the Yersinia bacterium were forced to leave their isolation and venture further and further to survive.  They met rats for the first time, and rats lived near human populations.  

Five years after the event, the plague first arrived.  150 million people died worldwide, and we learned about it from our history books.  The Black Plague that decimated the world started with climate change.  

Now, the climate is changing again, not due to a volcanic eruption or an asteroid hitting the earth, but because of our own actions.  Modern medicine gives us a sense of security we don't deserve, and in my lifetime HIV, Ebola, SARS, H1N1 and now Covid-19 have erupted and for the most part, been dealt with.

Today, wildfires are burning in California, Oregon, Colorado, and other places because of man-made climate change.  Here in Minnesota we've gotten used to hazy skies in the summer when wildfires burn in Canada.  

Bigger and badder hurricanes are hitting the coasts, one after another.  

We are actively working towards our own extinction event.
