CARBON DIOXDE AND TEMPERATURE PROFILE
Over the decades, the concentration of carbon dioxide has been increasing at a very rapid scale. This is due to the emission of these gases from different sources mainly due to human activities. The graph shows the trend of an increase of the gas and the global temperature. The reasons for Earth’s increasing temperature can be summarized as follows:
- Greenhouse gas: Greenhouse gas emissions, such as carbon dioxide, nitrous oxide and methane from automobile exhausts and industries, trap heat in the atmosphere.
- Deforestation: Extensive logging is removing trees and plants that would otherwise absorb carbon dioxide.
- Oceans’ absorption of carbon dioxide: Oceans help maintain a delicate equilibrium by absorbing carbon dioxide from the atmosphere and reflecting heat from the sun. But this balance is difficult to match with global carbon dioxide emission levels.
- Loss of sea ice: Glaciers help maintain the temperature of oceans, but with ice melting, there is less heat that is reflected back and more water to absorb it.
