Green house gasesGreen house gases
These gases like co2,methane,nitrous oxide These gases like co2,methane,nitrous oxide are responsible for trapping more infrared are responsible for trapping more infrared radiation from the sun thus increasing the radiation from the sun thus increasing the global temperature levels . global temperature levels .
This heat is absorbed by the oceans.This heat is absorbed by the oceans.
