Only that day dawns to which we are awake
Walden (1854)
Question
What do CO2 molecules and scientific publications have in common?
Answer

Their amounts are rapidly growing, and Chiem's job is to stay on top of both.



Question
Why would anyone be
a weather and climate scientist?
Answer

We need to know what to expect.
I for instance, research opportunities to predict hot, wet and dry events further in advance.
