There is also the ticking time bomb of the Camp Century remains:

> In 2016, a group of scientists evaluated the environmental impact and estimated that due to changing weather patterns over the next few decades, melt water could release the nuclear waste, 200,000 liters of diesel fuel, a nontrivial quantity of PCBs, and 24 million liters of untreated sewage into the environment as early as the year 2090. Transition in ice sheet surface mass balance at Camp Century from net accumulation to net ablation is plausible within the next 75 years under one climate model, and after another 44 to 88 years the buried wastes could be exposed between 2135 and 2179.

Is that really a ticking time bomb? We have massive oil spills all the time and Vancouver still pumps raw sewage into the ocean.

A concern and one we should fix, but a time bomb?
