Abstract The Miocene epoch (23.03–5.33 Ma) was a time interval of global warmth, relative
to today. Continental configurations and mountain topography transitioned toward modern …

Generalised dose–response curves are essential to understand how plants acclimate to
atmospheric CO2. We carried out a meta‐analysis of 630 experiments in which C3 plants …

Abstract The Permian–Triassic mass extinction was marked by a massive release of carbon
into the ocean-atmosphere system, evidenced by a sharp negative carbon isotope …

The geological record encodes the relationship between climate and atmospheric carbon
dioxide (CO2) over long and short timescales, as well as potential drivers of evolutionary …

Current atmospheric CO2 concentration is known to be higher than it has been during the
past∼ 800 ky of Earth history, based on direct measurement of CO2 within ice cores. A …

Abstract The Mid‐Pleistocene Transition (MPT), where the Pleistocene glacial cycles
changed from 41 to∼ 100 kyr periodicity, is one of the most intriguing unsolved issues in the …

Some experiments and observations of free-living plants have found that increasing
atmospheric concentration of CO 2 (pCO 2) is directly correlated with increasing …

The carbon atoms deposited in tree rings originate from the CO2 in the atmosphere to which
the tree's canopy is exposed. Thus, the first control on the stable carbon-isotope composition …

Widespread drought driven by global warming is predicted across the 21st century, just as
CO2 level is projected to as much as double over the same time period. However, the …

Understanding the evolution of, and the interactions between, ice sheets and the global
climate over geological timescales is important for being able to project their future …
