2 OUTLINE What drives climate system on our earth?
3 Fact 1: Solar radiation drives the earth s climate system OUTLINE The sun is a giant ball of hot gases 70% hydrogen, 28% helium, 0.5% carbon, 0.5% nitrogen, 0.5% oxygen, and 0.5% other elements.
4 Fact 1: Solar radiation drives the earth s climate system OUTLINE The creation of each helium nucleus requires four hydrogen nuclei. The converts 600 million tons of hydrogen into 596 million tons of helium every second.
5 Fact 1: Solar radiation drives the earth s climate system OUTLINE
6 Fact 1: Solar radiation drives the earth s climate system OUTLINE Atmospheric Effects
7 Fact 1: Solar radiation drives the earth s climate system the scattered component makes the sky look bright and provides the ambient diffuse daylighting used in buildings Blue light arrives from all directions after scattering, red and yellow light arrives almost directly from the sun OUTLINE Atmospheric Effects
8 Fact 1: Solar radiation drives the earth s climate system the scattered component makes the sky look bright and provides the ambient diffuse daylighting used in buildings Blue light arrives from all directions after scattering, red and yellow light arrives almost directly from the sun OUTLINE Atmospheric Effects
