Scientific modelling is a scientific activity, the aim of which is to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate by referencing it to...
Thirty Years Of Failed Climate Predictions
On June 23 1988, NASA's James Hansen testified before Congress and made very specific predictions about global warming. In this video I show how he got them exactly backwards, and how scientists and j...
Can Climate Models Predict Climate Change?
Predicting climate temperatures isn't science – it's science fiction. Emeritus Professor of Physics at Princeton University Will Happer explains. Donate today to PragerU! http://l.prageru.com/2eB2p0h ...
NASA Plans To Deploy Micro Satellites To Help Forecast Hurricanes: How Will It Work
The new microsatellites that NASA plans to deploy in space are said to improve weather forecasting on Earth. The operational aspect of this system is said to enhance data collection and thus enable sc...

Antarctic Sea Ice Did The Exact Opposite Of What Models Predicted
Climate models can be good tools for predicting future sea ice levels -- unless, of course, they are completely wrong.

Ensemble forecasting
Ensemble forecasting is a numerical prediction method that is used to attempt to generate a representative sample of the possible future states of a dynamical system. Ensemble forecasting is a form o...
Heisenberg model (quantum)
The Heisenberg model is a statistical mechanical model used in the study of critical points and phase transitions of magnetic systems, in which the spins of the magnetic systems are treated quantum me...

Cournot competition
Cournot competition is an economic model used to describe an industry structure in which companies compete on the amount of output they will produce, which they decide on independently of each other a...
Fujiwhara effect
The Fujiwhara effect, sometimes referred to as Fujiwara interaction or binary interaction, is when two nearby cyclonic vortices orbit each other and close the distance between the circulations of thei...
Long Tail
In statistics, a long tail of some distributions of numbers is the portion of the distribution having a large number of occurrences far from the "head" or central part of the distribution. The distrib...
Sun
The Sun is the star at the center of the Solar System. It is by far the most important source of energy for life on Earth. The Sun is a nearly perfect spherical ball of hot plasma, with internal conve...
