I recently had the incredible opportunity to visit Svalbard, Norway, an archipelago above the Arctic Circle about 600 miles from the North Pole. We were lucky enough to see polar bears, including a rare sighting of a Mom with 3 cubs.

The landscape was breathtakingly beautiful. But underlying the minute to minute magic was the sober message that the climate was warming and the ice was melting.
Just five years ago, the glacier in the background extended to the point where Dr Whitten is standing in Svalbard.
We passed glacier after glacier that used to fill the fjords we were sailing through, but which now clung to the sides of the canyon walls. Our ship, the National Geographic Explorer, was able to circumnavigate the Svalbard archipelago, something that has rarely been done because the northern ice usually blocks the eastern islands. Those polar bears, and indeed our planet, are in trouble.
However, I came home comfortable in my own mind that I was already doing my part to decrease global warming: using LED light bulbs, solar power, hybrid car, turning off all electrical devices when not in use. Ironically, I soon discovered that the anesthetic gases I use every day are some of the most potent greenhouse gases on the planet.
When we administer anesthesia, we pay a great deal of attention to the concentration of nitrous oxide and halogenated agents such as sevoflurane or desflurane that our patient receives. We know that too much or too little of these gases can harm our patients. We are often less compulsive about avoiding exposure to ourselves, or even our Operating Room colleagues to waste anesthetic gases. Therefore, to remind everyone of best practices on how to protect ourselves from exposure, I’ve been part of a team collaborating with our Workplace Safety department to create a training video on how to minimize Waste Anesthesia Gas (WAG) exposure.
