Abstract The chemical and isotopic composition of stony coral skeletons form an important archive of past climate. However, these reconstructions are largely based on empirical relationships often complicated by “vital effects” arising from uncer

The last glacial inception was characterised by rapid changes in temperature, atmospheric pCO2, and changes in the water mass geometry of the major ocean basins. Although several climatic feedback mechanisms have been proposed to explain the glacial/

Abstract Identifying the causes and consequences of natural variations in ocean acidification and atmospheric CO2 due to complex earth processes has been a major challenge for climate scientists in the past few decades. Recent developments in the bor

International audience; Earth's climate cooled markedly during the late Miocene from 12 to 5 million years ago, with far-reaching consequences for global ecosystems. However, the driving forces of these changes remain controversial. A major obstacle

Boron isotopes in planktonic foraminifera are a widely used proxy to determine ancient surface seawater pH, and by extension atmospheric CO2 concentration and climate forcing on geological time scales. Yet, to reconstruct absolute values for pH and C

Boron is a quintessential crustal element but its conspicuous presence in diamond – a mantle mineral – raises questions about potential subduction pathways for boron and other volatiles. It has been a long-standing goal to characterize the isotop

Ongoing changes in the Arctic cryosphere and ocean circulation have significant implications for regional and global climate. Past records of cryosphere-ocean-climate provide invaluable context to gain insight into future climate scenarios. However,

Atmospheric pCO2 is a critical component of the global carbon system and is considered to be the major control of Earth's past, present, and future climate. Accurate and precise reconstructions of its concentration through geological time are therefo
