GDP is a per annum calculation comprised of backward looking data. Market Cap is primarily a present value calculation based on forward looking expectations, on a perpetual basis. Both completely different statistics with completely different purposes.

This is a great visualization of one of the fundamental pieces of climate change: places are going to feel extreme changes to formerly fairly consistent weather patterns.

It’s shorts weather in Svalbard in January! And this is just two weeks after it was 30 degrees below average in Chicago on Christmas Eve. On average the globe warms a few degrees, but boy howdy are we feeling the effects in different ways.

Isn’t the purpose of visual data to make it more easily understandable for valid comparisons? This is like Purdue pharma showing logarithmic data and saying, you labeled it and they still don’t wanna read.

Depending on OPs intended conclusions it’s sort of misinformation or manipulation.

What is a therapeutic index (TI for short):

TI is a way of gauging a substance toxicity. It can be calculated in two different ways:

  • LD50 / ED50
  • TD50 / ED50

LD50: lethal dose in 50% of the test population

ED50: dose to achieve desired effects (in this case experiencing pyschoactivity) in 50% of the test population

TD50: dose to experience toxic effect in 50% of the test population

​

In this case all the values are calculated using the first method.

Keep in mind that the substances used are pure and in a lab environment.

Addressing inaccuracies:

As you might imagine calculating the TI of a given substance for humans is pretty hard, this data is based on animal studies and estimates based on death reports, so it might not be incredibly accurate. Also the therapeutic index calculated this way doen't directly measure how toxic a substance is for your body, although a broad therapeutic index generally implies a less toxic substance.

(?): since it's unknown if these substances can cause death in humans it's really hard to calculate their TI

(*): LD50 are all over the place for this substances, this is the best i could find.
