Even at this early stage, greenhouse-gas based models predicted temperatures that very closely match current observations.

The planner should take the model and, using real observations, assess the extent to which the output from the model matches real-world observations.

With a belt as Fernandez described it added to the formulations, the simulations matched observations.

In classical mechanics, this is not the case, the metric is fixed by the physicist to match experimental observations.

However, especially for simple models with few parameters, theoretical predictions may not match empirical observations for higher moments.

This matches observations of milder Arctic winters.

The works of Ptolemy (astronomy) and Galen (medicine) were found not always to match everyday observations.

The cloud-cosmic ray suggestion increasingly fails to match observations.

To match observations we would have to be very close to the centre of this void, immediately contradicting the Copernican principle.

The atmospheric circulation pattern that George Hadley described to provide an explanation for the trade winds matches observations very well.
