6.7 Activity: Investigate how climate modelling has changed over time

 Climate models have drastically improved from a century ago. Before the twenty century, climate models where use manually by sketching of equations on papers and solve the mathematical problems to forecast the climate change. This was the same method used to predict the weather.

From the 1960s, the climate models have improved by using computer programs that incorporate a wide range of physical, chemical, and biological processes that affect the Earth's climate.

Supercomputers are now used to solve complex mathematical equations that simulate the interaction between the atmosphere, cryosphere, lithosphere, and the biosphere. The improved models can now compute huge amount of data within less time than before. The global climate models can calculate global, regional and local data as may require than before.

 

Modern global climate models are based on complex mathematical equations that simulate interactions between the atmosphere, oceans, land surface, and ice sheets. They incorporate detailed data on atmospheric composition, greenhouse gas emissions, solar radiation, ocean currents, and other factors that influence the Earth's climate. However, these model still have uncertainty and limitation especially when it comes to analyzing data at local scale. they have become wide known for informing policy on adaptation decision making
