Climate has changed dramatically over geological timescales, it could be argued that the most noticeable change is the global temperature over the last 10,000 years. The changes in global temperature have led to the debate on climate change and discussion of factors that have led to climate change. When it comes to climate change, it is natural to think global temperature is increasing due to human causes such as deforestation. However, in some parts of the world, the temperature has decreased due to natural phenomenon. For example, Mount Pinatubo eruption in 2001 had led to a drop of 0.6 degree Celsius in average global temperature. Furthermore, variation in the Earth’s orbit around the Sun and cosmic collisions have an impact on the variation…show more content…
The peak of on the electromagnetic spectrum shows the type of the atmospheric composition present in the atmosphere. However, infrared absorption spectroscopy does not show precisely the percentage of the compound present in the atmosphere. Another limitation of using this instrument is scientists are unable to trace the climate in the past as infrared absorption method was discovered in the 1800s. Therefore, this measurement limit scientist to analyse the climate change from 1800 to recent. For example, there will be a higher peak for methane in the data shown recently compared to the measurement done in the past. This suggests that there is a change in the amount of methane gas present in the atmosphere which has led to a discussion of climate…show more content…
Variations in the greenhouse gas concentrations present in the atmosphere are known by comparing the modelled change over the astronomical cycles with observed paleoclimatic changes. The comparisons enabled scientists and researchers to observe the changes in climate and followed by an independent estimate of the changes in greenhouse gas concentration. The most notable changes by using this measurement are the concentration of carbon dioxide and methane as these gases are stored in peat, tundra, and ocean sediments during colder climates, and are released into the atmosphere in a warmer climate. Carbon dioxide and methane are being released have resulted in a warming effect. Computer modelling able to offer strong evidence to prove that the role of greenhouse gases in changing the past climate and will further affect the future
