Behavioral economics in action – climate change

If you were to count the number of times in a day that your actions do not match your intentions, in your opinion, what would the count be? It’s a perfect example of what behavioral economics rotates on; the famous intention-action gap. Here, Joshua Gordon, writing for FirstRand, gives everyday examples of how easily things […]

What are Earth System and Climate Models?

By US Department of Energy February 20, 2022 Earth system models and climate models are a complex integration of environmental variables used to understand our planet. Earth system models simulate how chemistry, biology, and physical forces work together. These models are similar to but much more comprehensive than global climate models. To understand Earth system […]

If the atmosphere is chaotic, how can we trust climate models?

Before they can understand how our planet’s climate is changing, scientists must first understand the basic principles of this complex system – the gears that turn Earth’s climate. You can create simple models with simple interactions, and that’s what happened in the first part of the 20th century. But from the 1950s and 1960s, researchers […]
