What was the largest volcanic eruption on Earth since the historic Mount Pinatubo eruption on 15 June 1991? Was the Toba super­eruption 74,000 years ago—the largest in the past 100,000 years—responsible for a human genetic bottleneck or a 1000-year-long glacial advance? What role did small volcanic eruptions play in the reduced global warming of the past decade? What caused the Little Ice Age? Was the April 2010 Eyjafjallajokull eruption in Iceland important for climate change? What do volcanic…

Radar Monitoring of Volcanic Activities

Earth is home to about 1500 volcanoes that have erupted in the past 10,000 years, and today volcanic activity affects the lives and livelihoods of a rapidly growing number of people around the globe.

Volcanism and Climate

The impact of volcanism on weather and climate is unequivocally documented by temporal correlations in both historical and prehistorical records. Although volcanic events have been traced far back

Did the 2011 Nabro eruption affect the optical properties of ice clouds?

The eruption of the Eritrean Nabro Volcano in June 2011 was the largest eruption since Mount Pinatubo in June 1991. The Nabro volcano emitted 1–1.5 megaton of sulfur dioxide into the lower

Some Perspectives on Societal Impacts of Past Climatic Changes

We examine a range of paleoclimatic evidence covering approximately the last 2000years (the Common Era) to provide plausible environmental scenarios as potential drivers and stressors associated with

100 Years of Progress in Understanding the Stratosphere and Mesosphere

The stratosphere contains ~17% of Earth’s atmospheric mass, but its existence was unknown until 1902. In the following decades our knowledge grew gradually as more observations of the stratosphere

Cloud and Surface Responses to Stratospheric Aerosols following Major Volcanic Eruptions

Major volcanic eruptions may inject large amounts of gases and aerosol particles into the lower stratosphere. Within weeks after an eruption, layers of aqueous sulfuric acid droplets will form from

Reply to Comment on “The Latest on Volcanic Eruptions and Climate”

I thank Johnson and Lane for pointing out details of their analysis, but there is still not enough information to evaluate their claim that Toba did not cause a significant cooling. They claim that

Equatorward dispersion of a high-latitude volcanic plume and its relation to the Asian summer monsoon: a case study of the Sarychev eruption in 2009

Abstract. Tropical volcanic eruptions have been widely studied for their significant contribution to stratospheric aerosol loading and global climate impacts, but the impact of high-latitude volcanic



Effects of Mount Pinatubo volcanic eruption on the hydrological cycle as an analog of geoengineering

The problem of global warming arises from the buildup of greenhouse gases such as carbon dioxide from burning of fossil fuels and other human activities that change the composition of the atmosphere

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

Abrupt onset of the Little Ice Age triggered by volcanism and sustained by sea‐ice/ocean feedbacks

Northern Hemisphere summer temperatures over the past 8000 years have been paced by the slow decrease in summer insolation resulting from the precession of the equinoxes. However, the causes of

Modeling the climatic effects of large explosive volcanic eruptions

Large volcanic eruptions are an important driving factor of natural climate variability. A sound assessment of the role of volcanoes in the climate system in comparison to other forcing factors is

Did the Toba volcanic eruption of 74 ka B.P. produce widespread glaciation

[1] It has been suggested that the Toba volcanic eruption, approximately 74 ka B.P., was responsible for the extended cooling period and ice sheet advance immediately following it, but previous

Ash from the Toba supereruption in Lake Malawi shows no volcanic winter in East Africa at 75 ka

The YTT in Lake Malawi is not accompanied by a major change in sediment composition or evidence for substantial temperature change, implying that the eruption did not significantly impact the climate of East Africa and was not the cause of a human genetic bottleneck at that time.

Volcanic eruptions and climate

Volcanic eruptions are an important natural cause of climate change on many timescales. A new capability to predict the climatic response to a large tropical eruption for the succeeding 2 years will

Late Pleistocene human population bottlenecks, volcanic winter, and differentiation of modern humans.

If Toba caused the bottlenecks, then modern human races may have differentiated abruptly, only 70 thousand years ago, and high genetic diversity in modern Africans may reflect a less severe bottleneck rather than earlier population growth.
