Climate Science
From modeling the worlds climate to fieldwork in remote locations, climate science takes on many different forms. But how does it really work? How can scientist know what the climate used to be like? How can scientific models help predict what the climate will be like in the future?

How Does Climate Modelers View the Earth?
As a part of the EVA project, where scientists developed the Norwegian Earth System Model, NorESM, a teaching tool was developed to show how climate modelers view the system around them.
Simulating Warm Climates of the Past
"Future climate scenarios are beyond any climate conditions of our recent past", researcher Petra Langebroek writes. When evaluating climate models, she finds it useful to see how they perform in the warm Eocene, 50 million years ago.
What it Like Living in Antarctica?
In this interview scientist and professor Elin Darelius talks about her experience on living more than two months in Antarctica.
Snowball Earth in an Earth System Model
Earth has been a snowball. In a new study, Heiko Goelzer and colleagues have used an Earth system model to study the transitions between a glaciated and a non-glaciated Earth, around 700 million years ago.
How Do Climate Supermodels Work
Climate researchers from Norway, the USA and the Netherlands have been developing a new efficient way to improve weather and climate predictions called supermodelling. Supermodelling is an AI technique incorporating the knowledge in physical models that climate modelers have been developing for decades. Watch how they work in this video.
The Norwegian Earth System Model
The Norwegian Earth System Model (norESM) is a climate model that solves mathematically formulated natural laws on a three-dimensional grid. The climate model divides the Earth system into components (atmosphere, ocean, sea ice, land with vegetation, ice sheets, etc.) that interact through the exchange of energy, momentum and moisture.
Tracing deep ocean currents
Radioactive isotopes typically take four years to reach the Norwegian coast from Sellafield on the north-eastern coast of England. Researchers like Yongqi Gao follow the radioactive waste to understand how ocean currents are formed and to see where they flow.
