Yellowstone National Park

Good question. I assume that all of current falls under historic, but that could not be the case.

Out of curiosity, I just looked up Alabama’s GDP, and it’s similar to the country of Portugal.

I assume they intentionally left out some to round out the numbers a bit and hit 50% in a more interesting way without over half of it being the US.

I can’t seem to find the original source, but based on search results, I’m seeing that this map has been circulating in similar circles to this and solar power communities since at least 2016.

Good luck finding land that is not near fracking sites. It’s been done basically everywhere, right?

I had to look it up because I had the same question, but the data came from photos of stuff from 1800.

I mean, if they can’t have the decency to be contiguous.

Probably just no more than 2 species in a given area, but not necessarily the same 2 in every area.

Plus sub-species, I assume.

There are a bunch of other cool maps too:

That’s a good round number to trigger a crisis that you’re getting old. Better start punching things to prove them all wrong.

Because otherwise the data would be artificially lower in areas with more children.

For example, imagine a suburb in Utah filled with college educated software engineers with big Mormon families. If you count the kids, it might look like people there don’t have degrees.

There is a researchgate link in the post body that has more info and a link to the publication. I haven’t skimmed through it myself, but I thought I’d link for anyone who’s curious.

I don’t know, a lot of the red is over pretty rural areas in the south and parts of the southwest, and the majority of the most rural parts of the country are “not significant”.

Also that big blue part in the middle covers some very large cities.

The darker color in tornado alley is green for “no data”, which is odd, but I assume it’s similar to the darker orange and red around it.

Yeah =(

The map tracks with high American Indian and White populations.

It looks like their source was the Eurostat Data Browser. Maybe these are just the countries it has data for?
