- Climatic signatures in early modern European grain harvest yields
Abstract: Climatic signatures in early modern European grain harvest yields
Fredrik Charpentier Ljungqvist, Bo Christiansen, Jan Esper, Heli Huhtamaa, Lotta Leijonhufvud, Christian Pfister, Andrea Seim, Martin Karl Skoglund, and Peter Thejll
Clim. Past, 19, 2463–2491, https://doi.org/10.5194/cp-19-2463-2023, 2023
We study the climate signal in long harvest series from across Europe between the 16th and 18th centuries. The climate–harvest yield relationship is found to be relatively weak but regionally consistent and similar in strength and sign to modern climate–harvest yield relationships. The strongest climate–harvest yield patterns are a significant summer soil moisture signal in Sweden, a winter temperature and precipitation signal in Switzerland, and spring temperature signals in Spain.

A Green Sahara with enhanced rainfall and larger vegetation cover existed in northern Africa about 6000 years ago. Biosphere–atmosphere interactions are found to be critical to explaining this wet period. Based on modeled vegetation reconstruction data, we simulated dust emissions and aerosol formation, which are key factors in biosphere–atmosphere interactions. Our results also provide a benchmark of aerosol climatology for future paleo-climate simulation experiments.

In 2018, a new 120 m ice core was drilled in a region located under the Antarctic ozone hole. We present the first results including a 1300-year record of snow accumulation and aerosol chemistry. We investigate the aerosol and moisture source regions and atmospheric processes related to the ice core record and discuss what this means for developing a record of past ultraviolet-radiation and ozone depletion using the stable isotopic composition of nitrate measured in the same ice core.

Stalagmites formed in caves provide valuable information about past changes in climate and vegetation conditions. In this contribution, we present a new method to better estimate past changes in soil and vegetation productivity using carbon isotopes and trace elements measured in stalagmites. Applying this method to other stalagmites should provide a better indication of past vegetation feedbacks to climate change.

This study analyses transient simulations of the last deglaciation performed by six climate models to understand the processes driving southern high latitude temperature changes. We find that atmospheric CO2 changes and AMOC changes are the primary drivers of the major warming and cooling during the middle stage of the deglaciation. The multi-model analysis highlights the model’s sensitivity of CO2, AMOC to meltwater, and the meltwater history on temperature changes in southern high latitudes.

The early twentieth century warming – the first phase of global warming in the 20th century – started from a peculiar cold state around 1910. We digitised additional ship log books for these years to study this specific climate state and found that it is real and likely an overlap of several climatic anomalies, including oceanic variability (La Niña) and volcanic eruptions.

The Pliocene (~3 million years ago) is of interest because its warm climate is similar to projections of the future. We explore the role of atmospheric carbon dioxide in forcing patterns of sea surface temperature during the Pliocene by combining climate model outputs with palaeoclimate proxy data. We investigate whether this role changes seasonally, and also use our data to suggest a new estimate of Pliocene climate sensitivity. More data are needed to further explore the results presented.

In this study, we test the use of excess meltwater from continuous flow analysis from a firn core from Greenland for the measurement of 10Be for solar activity reconstructions. We show that the quality of results is similar to the measurements on clean firn, which opens the possibility to obtain continuous 10Be records without requiring large amounts of clean ice. Furthermore, we investigate the possibility of identifying solar storm signals in 10Be records from Greenland and Antarctica.

The present paper upgrades our knowledge of Poland’s climate in the period 1001–1500 using multiproxy data. Four new climate reconstructions have been constructed – three based on dendrochronological data (since the 12th century) and one on documentary evidence (since the 15th century). The results should help improve the knowledge of climate change in Europe, particularly in central Europe.

We use multiproxy speleothem records to manifest a two drought-one pluvial pattern during 8.5–8.0 ka BP. The different rebounded rainfall amount after two droughts causes different behavior of δ13C, suggesting the dominant role of rainfall threshold on the ecosystem. A comparison of different records suggests the prolonged 8.2 ka event is a globally common phenomenon rather than a regional signal. The variability of the AMOC strength is mainly responsible for these climate changes.

To confirm this link between distant regions and to understand the reasons behind it, the information from different reconstructed and simulated products has been compiled and analyzed.

We report on a 3000-year record of carbon monoxide (CO) levels in the Southern Hemisphere's high latitudes by combining ice core and firn air measurements with modern direct atmospheric samples. Antarctica [CO] remained stable (–835 to 1500 CE), decreased during the Little Ice Age, and peaked around 1985 CE. Such evolution reflects stable biomass burning CO emissions before industrialization, followed by growth from CO anthropogenic sources, which decline after 1985 due to improved combustion.

This study is motivated by the current anthropogenic warming forced transition in regional hydroclimate. We use observations and model simulations during PETM, an anomalous greenhouse global warming event in the past, to constrain regional/local hydroclimate response. Our findings based on multi-proxy evidence within the context of model output suggest a transition to an overall drier climate punctuated by increased precipitation during summer in coastal California during the PETM.

We provided novel insights into the behaviour of a major upwelling cell between 15 and 8.5 million years ago. To study changing conditions, we apply a combination of geochemical and paleoecological parameters to characterize the nutrient availability and subsequent utilization by planktonic primary producers. These changes we then juxtapose with established records of contemporary monsoon wind intensification and changing high-latitude processes to explain shifts in the plankton community.

This reconstruction is validated by several methods and then presented using precipitation indexes. What is exceptional about this dataset is the availability of a sub-daily resolution and the low number of missing data points over the entire observation period.

A new federative chronology for five deep polar ice cores retrieves 800 000 years of past climate variations with improved accuracy. Precise ice core timescales are key to studying the mechanisms linking changes in the Earth’s orbit to the diverse climatic responses (temperature and atmospheric greenhouse gas concentrations). To construct the chronology, new measurements from the oldest continuous ice core as well as glaciological modeling estimates were combined in a statistical model.

Elevated atmospheric CO2 concentrations and a smaller Antarctic ice sheet during the mid-Pliocene (~3 million years ago) cause the Southern Ocean surface to become fresher and warmer, which affects the global ocean circulation. The CO2 concentration and the smaller Antarctic ice sheet both have a similar and approximately equal impact on the Southern Ocean. The conditions of the Southern Ocean in the mid-Pliocene could therefore be analogous to those in a future climate with smaller ice sheets.

Siberia is impacted by recent climate warming and experiences extreme hydroclimate events. We present a 220 year long sub-decadal stable oxygen isotope record of diatoms from Lake Khamra. Our analysis identifies winter precipitation as the key process impacting the isotope variability, highlighting two extreme dry periods. These two events were found to coincide with significant changes in lake internal conditions and increased wildfire activity in the region.

During at least two phases in its past, Earth was more or less covered in ice. These “snowball Earth” events probably started suddenly upon undercutting a certain threshold in the carbon-dioxide concentration. This threshold can vary considerably under different conditions. In our study, we find the thresholds for different distributions of continents, geometries of Earth’s orbit, and volcanic eruptions. The results show that the threshold might have varied by up to 46 %.
