The isotopic systems of boron and magnesium are increasingly being used as proxies for a number of environmental variables and processes. The isotopic composition of seawater for both systems plays a…

The plutonic archive is unlocked through hafnium (Hf) and oxygen (O) isotope analysis of zoned zircon crystals from the classic hornblende-bearing (I-type) granites of eastern Australia.

It is found that deep-sea temperature and sea level generally decreased through time, but distinctly out of synchrony, which is remarkable given the importance of ice-albedo feedbacks on the radiative forcing of climate.

Future climate forcing potentially without precedent in the last 420 million years
The evolution of Earth's climate on geological timescales is largely driven by variations in the magnitude of total solar irradiance (TSI) and changes in the greenhouse gas content of the atmosphere, and it is shown that the slow increase over the last ∼420 million years was almost completely negated by a long-term decline in atmospheric CO2.

The geological record contains long-term evidence for a variety of global environmental perturbations, including ocean acidification plus their associated biotic responses, over the past ~300 million years of Earth’s history.
Plio-Pleistocene climate sensitivity evaluated using high-resolution CO2 records

It is found that Earth’s climate sensitivity to CO2-based radiative forcing (Earth system sensitivity) was half as strong during the warm Pliocene as during the cold late Pleistocene epoch, and predictions of equilibrium climate sensitivity (excluding long-term ice-albedo feedbacks) for the Pliolithic-like future are well described.

The results confirm the central role of declining in the development of the Antarctic ice sheet (in broad agreement with carbon cycle modelling) and help to constrain mechanisms and feedbacks associated with the Earth’s biggest climate switch of the past 65 Myr.
