<h2>Continents and trends</h2>

A joint post with Steve Hempell

In another run with ver 1.2.1 Steve has focussed on the continents. The trends are interesting, and somewhat different. For comparison, we show the rather rough plot from the AR4 SPM (SPM 4), which seem to be in agreement.

The Output files for this and the previous post are now on the document store.

Table of trends

Trend	North America	South America	Europe	Africa	Asia	Australia
1900-2009	0.0724	0.0451	0.0909	0.0536	0.0973	0.0497
1900-1997	0.0451	0.0312	0.051	0.0218	0.0708	0.0501
1979-1997	0.0444	0.133	0.325	0.144	0.311	-0.169
1999-2009	0.00673	0.293	0.226	0.325	0.372	0.715

The last set of trends, for one decade only, are the least certain. All trends were calculated by OLS fitting.
