Has there ever been an oil spill in Yellowstone National Park? If so, how many?
The answer I get surprisingly often is "none". It is, after all, a National Park, right?
ArcGIS does a map overlay with the data of your choice. In this case the data is documented oil and gas spills since 2010, by type of spill and the SIZE of spill. Map for North America here. The size of the circle indicates the size of the spill. Note the big circles; size of the circle indicates the size of the spill. Blue is refined oil (gasoline, diesel, etc.). Red is NatGas. Since NatGas just vents into the atmosphere (unless it catches fire or is flared), it's a "clean" spill. Kinda. Natural Gas is a wicked greenhouse gas, with a warming factor of 80x more than carbon dioxide.
Yellowstone is in the northeast corner of Wyoming. Yellowstone has had two notable oil spills since 2010: an oil spill on the Exxon-Mobil pipeline in 2011, and another spill in 2015 from the pipeline owned by the True Companies. Those spills seem tiny compared to the thousands of spills throughout North America. No info from Canada though. There have been many oil spills in the Alaska pipelines that run all the way through Canada to the US.
Note that there are tens of thousands of old wells that have been abandoned; many have never been capped or have been poorly capped. Old wells are leaking massive amounts of oil and natgas. The big oil companies sell off the depleted wells to small companies. Those companies milk the well for a while and then go out of business.
"According to the Government Accountability Office, the 2.1 million unplugged abandoned wells in the United States could cost as much as $300 billion." from this Wikipedia article on Abandoned Wells in the United States.
There are abandoned oil wells everywhere: in the gulf, in Pennsylvania,
in Texas, in California. And that is in the USA where there are better
regulations than most countries. Read about the Biden effort to go out
and cap them at the NRDC. There are lots of other sources, but you get the idea.
you think of the costs to the environment, the costs to clean up, and
the costs to not cleanup, the costs are massively greater than what you
pay at the gas meter or at the pump. And yet the world's governments
still subsidize fossil fuels at the rate of $1T per year. According to the IMF, explicit fossil fuel subsidies are about 1% of GDP, but implicit is 6% to 7% of GDP (about $6T USD).
