Trend Analysis in the Context of Global Warming Keywords: anthropogenic climate change, climate, climate change, trend analysis

There are many sources ranging from politicians to mass media that claim that the Earth is actually cooling, not warming as scientists say it is. Unusually cold periods and local changes in weather are generally the cause for these statements. Why are these claims inaccurate?

There are many claims made refuting the existence of global warming. Most of these claims come from looking at very short term data in a very localized region. Global warming, as the name implies, is an increase in the global temperature and conclusions about it cannot be reached using measurements localized in time and space. Doing so is called "cherry picking".

Climate Models: Simulating the Earth Keywords: climate, climate change, simulating data

Climate models can give us a great deal of information about what sort of rules the climate follows and how the climate might look like in the future. A climate model is the result of a simulation run on a virtual Earth. This simulation mimics the real Earth and its climate as well as any influences the planet might have on the climate. They are used to predict the future of the climate using computers.

The prediction of future climate is done using climate models, virtual Earths with their climates simulated many years into the future. These virtual Earths live inside computers and evolve according to complex equations solved for points in time. The results that these climate models give provide us with important information to make decisions relating to climate change before we encounter the potentially catastrophic consequences.
