Additional uncertainty in these calculations arises from the assumption that a 10 per cent GST has the same effect on the retail price as a 10 per cent WST, even though the WST is levied at an earlier stage of production and therefore represents a smaller amount of tax for a given tax rate.

Their latest calculation, based on the oldest light that telescopes can detect, is 14.0 billion years with an uncertainty of just 500 million years — the tightest age constraint yet, and slightly older than the going estimate of around 13 billion years.

«Our results show that the uncertainty estimates of greenhouse gas inventories depend on the calculation method and on how the input data for the model, such as weather and litterfall data, have been averaged,» says Aleksi Lehtonen, researcher at the Natural Resources Institute Finland (Luke).

There is a quantitative effect of this error, both on global average calculations up to the 1970's and on the uncertainty of that number.

Depending on what you are looking at, it could have a bottom up estimate of aerosol forcing or aerosol forcings from a residual calculation — neither of which really have the range of uncertainty.

There are uncertainties in parts of the general circulation models used to forecast future climate, but thousands of scientists have made meticulous efforts to make sure that the processes are based on observations of basic physics, laboratory measurements, and sound theoretical calculations.

The present method of making this calculation relies on sparse enough data stations that improvement is quite possible since the uncertainty introduced by interpolation could be reduced.

These are the probabilities of the given years being the warmest on record, using calculations based upon the uncertainties (and the shape of those uncertainties) associated with each year's value.

Structural uncertainty is attenuated when convergent results are obtained from a variety of different models using different methods, and also when results rely more on direct observations (data) rather than on calculations.

And to your point, they also only focus on the lower bounds of uncertainty, poo poo the the statistically most likely figure, and act as though the highest uncertainty figure wasn't even part of the calculation.

These calculations, based on ERBE and CERES observational data, are themselves subject to considerable uncertainty, but are consistent with a positive imbalance (more incoming than outgoing energy) that would be expected from greenhouse gas forcing.

It turns out that Nic had an abridged version of his calculation back on the Quantifying Uncertainties thread some weeks ago, see his comment here.

Our best estimate is based on the data (both temps and proxies) we have, the physics we know, and the proper application of uncertainty calculations.

A more detailed model of the dynamics of the changes might have a small effect on the outcome, but not at a level that would make any difference in comparison with the other uncertainties of the calculation.

Unlike the precision on scientific calculations where digits are discarded due to uncertainty in the components, for Big Data — the greatest single component accuracy is used as a basis for all the rest!

I am still working on some uncertainties in the calculation and lowering the amount.
