Today, I have a fun story to share. I know a teacher who instructs Thermodynamics (a subject I failed). We have classes every Thursday afternoon.

As everyone sat in the room waiting for the teacher,he walked in and announced, "Have you heard the news? International scientists are urging governments to prioritize addressing global warming before it reaches a point of no return."

After the teacher finished speaking, I thought, "The teacher must want us to get involved since we're students, the new generation." Later, the teacher drew a diagram on the board (I attempted to draw it here, but apologies if there are errors).

It depicted us placing the sun and Earth into a system, defining what objects we want to consider in this system (what we are interested in),we called “system boundary” in thermodynamics. The outer boundary had nothing (as the universe hasn't expanded yet), and inside was our solar system. It simplified to placing Earth and the sun into the same glass of water.

Applying the first law of thermodynamics (energy doesn't disappear, just changes form), let's say we have a very hot sun dunked into a glass with a slightly cool Earth. Initially, the water around the sun would heat up, transferring energy to the Earth until everything reaches the same temperature.

Connecting this to the zeroth law of thermodynamics (the temperatures of A and B are equal, and B and C are equal, so A and C are equal), it concludes that the temperatures of the sun, Earth, and the water in the glass would be the same. In this scenario, if there were more planets in the solar system, they would help distribute the heat.

The teacher then said, "In reality, we haven't had a point of no return from the start. Some just see the benefits of profiting from global warming."

The teacher's perspective on global warming is thought-provoking. Apologies if there are any mistakes in my explanation.
