Journal ArticleDOI
Rapid 20th-century increase in coastal upwelling off northwest Africa.
TL;DR: It is suggested that coastal upwelling varies with NHTAs and that up welling off northwest Africa may continue to intensify as global warming and atmospheric CO2 levels increase.
Journal ArticleDOI

TL;DR: A community-sourced database of temperature-sensitive proxy records from the PAGES2k initiative, suited to investigations of global and regional temperature variability over the Common Era, and is shared in the Linked Paleo Data (LiPD) format, including serializations in Matlab, R and Python.
Journal ArticleDOI
Early onset of industrial-era warming across the oceans and continents
Nerilie J. Abram,Helen McGregor,Jessica E. Tierney,Jessica E. Tierney,Michael N. Evans,Nicholas P. McKay,Darrell S. Kaufman +6 more
TL;DR: The authors used post-ad 1500 palaeoclimate records to show that sustained industrial-era warming of the tropical oceans first developed during the mid-nineteenth century and was nearly synchronous with Northern Hemisphere continental warming.

TL;DR: In this article, an interlaboratory study of coral Sr/Ca measurements was conducted and the results showed that the bias can be significant, and in the extreme case could result in a range in SST estimates of 7°C.
Early Onset of Industrial-Era Warming Across the Oceans and Continents
Nerilie J. Abram,Helen McGregor,Jessica E. Tierney,Jessica E. Tierney,Michael N. Evans,Nicholas P. McKay,Darrell S. Kaufman +6 more
TL;DR: The findings imply that instrumental records are too short to comprehensively assess anthropogenic climate change and that, in some regions, about 180 years of industrial-era warming has already caused surface temperatures to emerge above pre-industrial values, even when taking natural variability into account.
