Question

1.Who is the scientist who first showed the impact of changing levels of CO2 on atmospheric temperature?

Jean Baptiste Joseph Fourier

Svante Arrhenius

Gavin Norman Plass

E. O. Hulbert

2. When did this scientist (from question 1) first publish these results?

a.

1960

b.

1957

c.

1896

d.
