What did scientists discover after their glacier investigation?
Periods of higher CO2 concentrations coincide with periods when the Earth was warmer.

What process removes CO2 from the atmosphere? What is the recent problem humans are having with such process?
Photosynthesis. Deforestation is resulting in the reduction of CO2 removal, which causes a bigger concentration of such.

Why did scientists choose glaciers to prove their hypothesis about climate change & the concentration of CO2?
Ice builds up over thousands of years â ice from deeper down is older than ice near the surface, therefore they could observe CO2 ratios from years ago

How did scientists prove their hypothesis regarding climate change?
They did an expedition to Antarctica. Here, they extracted and analyzed trapped air bubbles from glaciers to observe C02 ratios.
