The large AD 1258 eruption had a stratospheric sulfate load approximately ten times greater than the 1991 Pinatubo eruption. Yet surface cooling was not substantially larger than for Pinatubo (∼0.4 K). We apply a comprehensive Earth System Model to demonstrate that the size of the aerosol particles needs to be included in simulations, especially to explain the climate response to large eruptions. The temperature response weakens because increased density of particles increases collision rate… 

Aerosol size confines climate response to volcanic super‐eruptions

Extremely large volcanic eruptions have been linked to global climate change, biotic turnover, and, for the Younger Toba Tuff (YTT) eruption 74,000 years ago, near‐extinction of modern humans. One of

The unidentified volcanic eruption of 1809: why it remains a climatic cold case

Abstract. The 1809 eruption is one of the most recent unidentified volcanic eruptions with a global climate impact. Even though the eruption ranks as the 3rd largest since 1500 with an eruption

Resolving the Differences in the Simulated and Reconstructed Temperature Response to Volcanism

Explosive volcanism imposes impulse‐like radiative forcing on the climate system, providing a natural experiment to study the climate response to perturbation. Previous studies have identified

The unidentified volcanic eruption of ~1809: why it remains a climatic cold case

The “1809 eruption” is one of the most recent unidentified volcanic eruptions with a global climate impact. Even though the eruption ranks as the 3rd largest since 1500 with an eruption magnitude a

Climate response to the Samalas volcanic eruption in 1257 revealed by proxy records

The eruption of Samalas in Indonesia in 1257 ranks among the largest sulfur-rich eruptions of the Common Era with sulfur deposition in ice cores reaching twice the volume of the Tambora eruption in

Global and Polar Region Temperature Change Induced by Single Mega Volcanic Eruption Based on Community Earth System Model Simulation

In order to understand the pure long‐term influence of single mega volcanic eruption (SMVE) of universal significance on global and polar region temperature changes, the AD 1258 Samalas mega volcanic

Earth System Model Response to Large Midlatitude and High‐latitude Volcanic Eruptions

We used the Meteorological Research Institute Earth System Model to simulate the climate response to massive sulfur dioxide (SO2) emission from the volcanic eruptions of Paektusan (China/North Korea)

Estimates of volcanic-induced cooling in the Northern Hemisphere over the past 1,500 years

Explosive volcanism can alter global climate, and hence trigger economic, political and demographic change1, 2. The climatic impact of the largest volcanic events has been assessed in numerous

Cooling following large volcanic eruptions corrected for the effect of diffuse radiation on tree rings

The lack of a larger cooling in proxy records of climate change following large volcanic eruptions such as those of Tambora in 1815 and Krakatau in 1883 has long been a puzzle for climatologists.

Ice core and palaeoclimatic evidence for the timing and nature of the great mid‐13th century volcanic eruption

Ice cores from both the Arctic and Antarctic record a massive volcanic eruption in around AD 1258. The inter‐hemispheric transport of ash and sulphate aerosol suggests a low‐latitude explosive

The role of microphysical and chemical processes in prolonging the climate forcing of the Toba Eruption

The mega-eruption of Toba, Sumatra, occurred around 73 Ka ago, during the onset of a glaciation of the Late Quaternary. This coincidence combined with the unprecedented amount of sulphur released by

Climate sensitivity constrained by temperature reconstructions over the past seven centuries

TLDR
An independent estimate of climate sensitivity is found that is very similar to those from instrumental data, and if the latter are combined with the result from all proxy reconstructions, then the 5–95 per cent range shrinks, thus substantially reducing the probability of very high climate sensitivity.
