After a wild weather year across the nation, wildfire season is at bay and winter weather games are in play. In this reduced heat of the moment, and with relatively cool heads (until the next bombogenesis), it’s a good time to consider the natural and man-made temperature regulators that are key to keeping our planet livable, our food preserved and our bodies hovering at 98.6 degrees Fahrenheit.
I’m talkin’ ‘bout refrigeration.
As the earth’s natural refrigerating heat shield vanishes with accelerated glacier melts — causing more accelerated glacier melting — solutions for a cooler atmosphere must aggressively include slowing this perilous process.
But this is only one of the vicious cycles at play. For the hotter the planet becomes, the more man-made cooling we need for our bodies and our food systems. And the more cooling we deploy with the power of fossil fuels, the more greenhouse gases (GHGs) we generate — and the hotter the planet becomes.
The condition of our cooling systems
The energy it takes to run cooling machines needs to be managed efficiently and generated renewably. GreenBiz Editorial Director Heather Clancy recently reviewed the state of the art of energy productivity as it applies to cooling and refrigeration. The demand from air conditioning alone could triple by 2050, so a key focus for some is on the cooling facilities used by people. At the same time, others are focused on improving cold-chain logistics with artificial intelligence and the internet of things — smartly allowing the thermal properties of super-cold food to, well, keep food cold.
