please help! thanks

Has anybody read the poem Calgary 2am?

If so, can anyone help me analyze the poem? It seems that it is very confusing and I can not "solve" the poem.

Thanks!

The greenhouse effect is a natural phenomenon that occurs when certain gases in the Earth's atmosphere trap heat from the sun, causing an increase in surface temperature. This process is important for maintaining the Earth's average temperature and making the planet habitable, but it becomes problematic when human activities contribute to an excessive buildup of these gases, leading to global warming.

The greenhouse effect is a natural process that occurs when certain gases in Earth's atmosphere trap the heat from the sun, preventing it from escaping back into space. This trapped heat warms the Earth's surface and is essential for supporting life.
