The Intermittent Little Ice Age

by Tony Brown Is our popular understanding of the ‘Little Ice Age’ (LIA) correct, as being a predominantly cold era lasting 500 years, leavened by a few brief warm spells?

Early 20th century Arctic warming

by Judith Curry “Arctic temperature anomalies in the 1930s were apparently as large as those in the 1990s and 2000s. There is still considerable discussion of the ultimate causes of the warm temperature anomalies that occurred in the Arctic in … Continue reading

The long, slow thaw?

by Tony Brown A warming trend can be observed from 1659, the start date of Central England Temperature  (CET)- the oldest instrumental record in the world- to today.  It would be a notable coincidence if the warming started at the … Continue reading

IPCC discussion thread

by Tony Brown Posts in the thread on uncertainty guidance for the IPCC have raised a basic question regarding the credibility of the IPCC as the world’s foremost source of information on climate, and hence its future relevance.

Historic variations in sea levels. Part 1: From the Holocene to Romans

by Tony Brown The IPCC AR4 projected sea level rise in 2100 to range from 18-59 cm, depending on  the emission scenario.  More recent projections are for a 1 m sea level rise in 2100 [here and here].  Apart from … Continue reading

Unknown and uncertain sea surface temperatures

by Tony Brown Over the years I have become intrigued at the manner in which historic surface temperature records- that were never intended to be more than a broad reflection of the micro climate around them- have been used as … Continue reading
