Dear readers, this article expects you to have reasonable understanding of climate and environment as the topic is quite advanced in its nature. Let us delve into the realm of Climate Models, a crucial aspect in comprehending and forecasting the alterations of our beloved planet, Earth’s climate. These models, like a symphony, simulate the interplay between the atmosphere, ocean, land, and sea ice. They serve as seers, predicting the future changes in temperature, precipitation, sea level and other climate variables.

The Representative Concentration Pathways (RCPs) offer a glimpse into the future, portraying the potential greenhouse gas emissions and their impact on our climate. The results obtained from diverse climate models, through the lens of RCP scenarios, paint a consistent picture of warming, primarily caused by human actions. Though the projections may carry some degree of uncertainty, the overall trend aligns with observational data and the historical records of our planet’s climate.

There are many different models that have been developed to simulate and understand the Earth’s climate. These models are used to project future changes in temperature, precipitation, sea level, and other climate variables based on different scenarios of greenhouse gas emissions. Let’s look at some of the models first:
