Implication of methodological uncertainties for MH SST reconstructions

University ’ s repository of research publications and other research outputs High - resolution alkenone palaeobarometry indicates relatively stable pCO

14 Temperature reconstructions indicate that the Pliocene was ~ 3 °C warmer globally 15 than today, and several recent reconstructions of Pliocene atmospheric CO2 indicate 16 that it was above pre-industrial levels and similar to those likely to be seen this 17 century. However, many of these reconstructions have been of relatively low temporal 18 resolution, meaning that these records may have...

Analyses of Oceanic Total Cloudiness and Some Relationships with Precipitation and SST Beginning 1900

Oceanic cloudiness, precipitation, and sea-surface temperature (SST) are important and related climate fields. Here development of a new historical analysis of total cloudiness over the oceans is described. Some joint evaluation of cloudiness, SST, and precipitation is done to help to give an overall picture of how these variables change and interact on regional to global scales since 1900. Int...

Estimating 750 years of temperature variations and uncertainties in the Pyrenees by tree-ring reconstructions and climate simulations

Past temperature variations are usually inferred from proxy data or estimated using general circulation models. Comparisons between climate estimations derived from proxy records and from model simulations help to better understand mechanisms driving climate variations, and also offer the possibility to identify deficiencies in both approaches. This paper presents regional temperature reconstru...
