Yes. Climate models are computer programs which simulate the climate or weather patterns over time. They can be used to estimate the Earth’s climate under different conditions by running simulations. Climate model computer programs use techniques that divide the atmosphere, land, ocean and ice into layered boxes or grid cells to create a 3-dimensional framework. Each grid cell represents a section of the atmosphere, land or ocean. The results of processes modelled in each grid cell influence neighbouring cells. For... View Article

Greenhouse gases trap the heat in the atmosphere. They keep the surface temperature of the Earth warmer, acting as insulation. As the sun warms the Earth, it causes the surface to radiate heat which is absorbed by greenhouse gases. The main greenhouse gases are carbon dioxide, methane, nitrogen oxide, chlorofluorocarbons, ozone and water vapour. These gases absorb the infrared radiation causing the temperature to rise. Without greenhouse gases, the average temperature of Earth’s surface would be freezing, about -18C.

Climate models are computer programs which simulate the climate or weather patterns over time. They can be used to estimate the Earth’s climate under different conditions by running simulations. Climate models are powerful tools for simulating, analysing and understanding the Earth’s climate. They are used to understand how our planet is changing and are fundamental to climate science. They help us understand how the climate is affected by emissions, economic growth, technological developments, and political and social change. They can... View Article

Climate variability is a transient change in the climate, above or below the long term average. This can occur on different timescales. Natural variability is the main reason for year to year differences in our climate. There are many different processes that interact to influence the climate we experience. Natural variability refers to changes in the climate that occur due to factors other than human influence. These include processes such as large scale climate modes like the El Niño Southern...

The weather is what we experience in a location over a few days. The weather is the state of the atmosphere at a particular time. The climate is what to expect in any month, season, or year. Climate is the long-term description of the average atmospheric conditions over many years.

As the tropical climate warms, the intensity of rainfall and winds associated with the Madden-Julian Oscillation as well as their patterns may change, leading to intense debate and scrutiny of how extratropical weather will be affected.
