🏡 Here is the data analysis for Calgary, Summer 2025. This chart shows the relationship between vegetation density (NDVI) and Land Surface Temperature (LST).

🔥 The data reveals a critical "tipping point": vegetation only starts effectively cooling the environment once it reaches a specific density threshold. Below this threshold (the left side of the curve), green spaces stay just as hot as the surrounding concrete.
Sparse or isolated trees don't act as air conditioners—they "burn" in the urban furnace right along with us.

❗ What does this mean for Calgary? Simply planting a few scattered trees isn't enough. To actually move the needle on temperature, we need dense, healthy green belts. Otherwise, it’s just a waste of water and resources.

N.B. This is a draft, and this is as much about practicing publications with ghost as it is about generating debate

First CRAN submission to acceptance: 11 days, three rounds. The first rejection was one missing tag in one documentation file.

left_join in R is silent when keys aren't unique. It just multiplies rows. The output has more rows than the input and nothing tells you.
