Revisiting the Holocene global temperature conundrum

Darrell S. Kaufman et al.

Summary: This review examines evidence from indicators and drivers of global change to evaluate whether anthropogenic global warming was preceded by a long-term warming trend or by global cooling. It finds that multimillennial-scale cooling before industrialization requires extra climate forcing and major climate feedbacks, while global warming challenges proxy-based reconstructions of past climate. The resolution of this conundrum has implications for understanding climate sensitivity and advancing our understanding of slow-moving climate variability.

FROG: A global machine-learning temperature calibration for branched GDGTs in soils and peats

Pierre Vequaud et al.

Summary: The study developed a new global terrestrial brGDGT temperature calibration using a machine learning algorithm. This improved model is more accurate and robust than previous global soil calibrations, and takes into account non-linear relationships to better represent environmental complexity.

In-situ provenance of brGDGTs in peat sediments: A case study from southern China and a comparison of global results

Shikai Wei et al.

Summary: This study investigates the origin of brGDGTs in the Shiwangutian peatland in southern China and finds that they are primarily generated in-situ. Similar conclusions are drawn from comparisons of globally-distributed surface peat sediments and surface soils. Additionally, the origin of brGDGTs may vary in specific environments.

Pollen Data as a Temperature Indicator in the Late Holocene: A Review of Results on Regional, Continental and Global Scales

Zhiguo Rao et al.

Summary: The temperature history of the Holocene is debated due to the unreliable nature of pollen records, mainly caused by human impacts on terrestrial vegetation. Therefore, it is important to consider the possible human impacts on terrestrial Holocene temperature records and use proxies that are insensitive to human impacts for late Holocene climatic reconstruction.

Seasonal imprint of Holocene temperature reconstruction on the Tibetan Plateau

Can Zhang et al.

Summary: The Tibetan Plateau is one of the most sensitive areas to global climate changes. Research shows that the warming during the Last Deglaciation was primarily driven by rising atmospheric greenhouse gases, while Holocene temperature changes were mainly controlled by local seasonal insolation and additional radiative forcing of greenhouse gases.

Influence of water conditions on peat brGDGTs: A modern investigation and its paleoclimatic implications

Zhiguo Rao et al.

Summary: This study compares surface peat samples from peatlands with different environmental conditions in China, and finds that water conditions have a clear influence on the molecular distribution of peat brGDGTs. This indicates that factors other than temperature can affect the interpretation of brGDGTs as temperature indicators.

Reconstructing Holocene temperatures in time and space using paleoclimate data assimilation

Michael P. Erb et al.

Summary: Paleoclimatic records provide valuable information about Holocene climate, but also have limitations such as uneven proxy networks and seasonal biases. Paleoclimatic data assimilation is an effective method to reconstruct past climate by considering the diversity of proxy records and the simulated covariance structures of climate models.

Globally resolved surface temperatures since the Last Glacial Maximum

Matthew B. Osman et al.

Summary: Utilizing paleoclimate data assimilation, a reanalysis of global surface temperature over the past 24,000 years has been conducted, showing a slight but steady increase in global mean temperature since the early Holocene by about 0.5 degrees Celsius. The study reveals that the rate and magnitude of modern warming are unusual compared to changes over the past 24,000 years, with key climatic mechanisms including radiative forcing from ice sheets, greenhouse gases, changes in ocean overturning circulation, and seasonal insolation.

Seasonal origin of the thermal maxima at the Holocene and the last interglacial

Samantha Bova et al.

Summary: Proxy reconstructions show that peak temperatures in the Holocene and the last interglacial period may have exceeded modern warmth, contradicting monotonic warming simulated by climate models. The discrepancy between model results and reconstructions undermines confidence in both, but indicates different climate dynamics between the two periods due to changes in greenhouse gas levels and ice sheet extent. The study suggests that the early Holocene was cooled by larger remnant glacial ice sheets, while rising greenhouse gas levels in the late Holocene warmed the planet. Modern global temperatures may have surpassed those of the past 12,000 years and could approach the warmth of the last interglacial period.

Oxygen limitation can trigger the production of branched GDGTs in culture

T. A. Halamka et al.

Summary: The study reveals that oxygen limitation triggers brGDGT production in at least one cultured species of Acidobacteria and confirms the biosynthesis of three structural varieties of brGDGTs. This discovery helps explain the difficulty in identifying brGDGT producers and provides a pathway towards uncovering the genetic basis and biological function of brGDGTs. It suggests that the effects of oxygen as a relevant and possibly dominant control in the environmental distributions of brGDGTs may be missing in current empirical calibrations for temperature and pH reconstructions based on brGDGTs.

Elevational differences in Holocene thermal maximum revealed by quantitative temperature reconstructions at ∼30° N on eastern Tibetan Plateau

Tianlong Yan et al.

Summary: Meteorological data indicates that temperature increase in high-elevation areas on the eastern Tibetan Plateau is much higher than the global average, with a peak warmth in the middle Holocene. The timing of the Holocene Thermal Maximum in high-elevation sites lags behind that in low-elevation sites, possibly due to offset of remaining regional glaciers and/or snow cover. The enhanced warming with elevation can be attributed to snow albedo and latent heat release.

Global acceleration in rates of vegetation change over the past 18,000 years

Ondrej Mottl et al.

Summary: Over the past 18,000 years, global vegetation has undergone significant changes due to both climate fluctuations and increasing human activities. Utilizing fossil pollen sequences and statistical methods, researchers have observed a remarkable acceleration in vegetation compositional change globally, starting between 4.6 and 2.9 thousand years ago, surpassing any previous changes over the last 18,000 years.
