Historic risk data and 10-day weather forecasts are no longer enough to plan disaster response and decide locations for hospitals, schools, and housing.

Current models calculate climate futures in a grid of cells that approximate processes on land, water, and air. But their resolution is so coarse they can account for only limited features.

For decades, scientists studying a key climate phenomenon have been grappling with contradictory data that have threated to undermine confidence in the reliability of climate models overall. A new ...

Talk to someone who rejects the conclusions of climate science and you’ll likely hear some variation of the following: “That’s all based on models, and you can make a model say anything you ...

These models divide the planet into a three-dimensional grid, with each cell representing a specific portion of the atmosphere or ocean. Equations are then applied to simulate physical processes ...

The climate sensitivity of these models spanned 1.8-5.6°C for doubled CO 2, with an average of 3.9°C. The last generation fell into 2.1-4.7°C, with an average of 3.3°C.

The horizontal size of cells in current global climate models is roughly 100 kilometres. This resolution is fine enough to simulate mid-latitude weather systems, which stretch for thousands of ...

For each of the 86,400 cells related to the atmosphere, ... So there is still a gap between weather models and climate models and, using E3SM, we are trying to close that gap." RELATED TOPICS ...

Halving the size of cells requires roughly ten times more computing power; today’s models, thousands of times more powerful, can simulate cells of around 50km per side. Read more: Climate change ...

Instead of trying to figure out what Earth’s climate would look like in 50 or 100 years, this model would predict what your pizza would look like when it was done. The Earth’s climate is like ...
