Jones the global temperature

Posted in: News and Updates

The I-SEE seminar on Tuesday 30 October 2018 [ 1630 to 1745 ] is by Professor Phil Jones, Climate Research Unit Environmental Sciences, University of East Anglia.  His title is:

‘The global temperature average: a history, recent changes and their context over the Late Holocene’

Here's the abstract:

Global temperatures have risen during the 20th century, and have continued to rise during the present century. The warmest 5 years are the last five, with 2016 the warmest followed by 2015, 2017, 2018 and 2014. The talk will begin discussing the history of the global temperature series, highlighting some important earlier work, and also illustrating how relatively few series are required to produce it. Many more series are used, as producers want a gridded product at as small a scale as possible to look at patterns of change. The talk will further address the robustness of the record, and what the important issues are with respect to biases and homogeneity. The most important relates to the way sea surface temperatures have been taken over the course of the 20th century, and if this isn’t taken into account, the long-tern warming would be greater.  The talk will then discuss the various factors that influence the climate on decadal and longer timescales. The final part of the talk will place the record from 1850 in the context of the last 2000 years, and discuss the warming in the context of the pre-industrial average, which until recently wasn’t defined.

See you there!
