The eruption of Mount Pinatubo on 15 June 1991 produced the largest stratospheric volcanic aerosol cloud of the 20th century. About 20 megatons of SO2 was injected into the stratosphere, affecting global climate for years. In his Perspective, Robock discusses the climatic lessons learned from the Pinatubo eruption. An accompanying Perspective by Newhall et al . discusses the geologic insights gained from the eruption. 
The effects of volcanic eruptions observed in satellite images: Examples from outside the North Pacific region
The effect of a volcanic eruption by liberating magma, gases, and energy is to modify the Earth’s surface and its atmosphere. Quite how these changes are produced depends on the nature of the
Introduction: Mount Pinatubo as a Test of Climate Feedback Mechanisms
The June 15, 1991 Mount Pinatubo eruption was a large but relatively shortlived shock to the Earth’s atmosphere. It thus provided an excellent opportunity to study the workings of the climate system,
The Arctic Polar Vortex Response to Volcanic Forcing of Different Strengths
Large explosive volcanic eruptions can inject sulfur into the stratosphere, which forms sulfate aerosols and leads to global mean surface temperature reductions and changes in atmospheric circulation
Response of a Deciduous Forest to the Mount Pinatubo Eruption: Enhanced Photosynthesis
It is found that the aerosol-induced increase in diffuse radiation by the volcano enhanced the terrestrial carbon sink and contributed to the temporary decline in the growth rate of atmospheric carbon dioxide after the eruption.
Volcanoes and climate
Of the natural forcings causing short-term climatic variations, volcanism, along with its climatic impact, is perhaps the best understood. The primary net result of the impact is the reduced receipt
An AOGCM simulation of the climate response to a volcanic super-eruption
Volcanic ‘super-eruptions’ have been suggested to have significantly influenced the Earth’s climate, perhaps causing glaciations and impacting on the human population. Climatic changes following a
Weather from the Stratosphere?
Unlike the turbulent troposphere, the stratosphere--the atmospheric layer from 10 to 50 km--has long been believed not to play a substantial role in determining weather and climate at Earth9s
Modeling the lava heat flux during severe effusive volcanic eruption: An important impact on surface air quality
The April 2007 eruption of Piton de la Fournaise, one of the most active volcanoes in the world, was the strongest eruption in recent decades with 230Mm3 of lava emitted and more 300KT of SO2
Interaction between climate, volcanism, and isostatic rebound in Southeast Alaska during the last deglaciation
Abstract Observations of enhanced volcanic frequency during the last deglaciation have led to the hypothesis that ice unloading in glaciated volcanic terrains can promote volcanism through
Effects of Large Volcanic Eruptions on Global Summer Climate and East Asian Monsoon Changes during the Last Millennium: Analysis of MPI-ESM Simulations
AbstractResponses of summer [June–August (JJA)] temperature and precipitation to large volcanic eruptions are analyzed using the millennial simulations of the earth system model developed at the Max


Further studies on possible volcanic signal to the ozone layer
In this paper the authors report the results of a study of the global ozone profiles, following the eruptions of El Chichon and Mt Pinatubo, after factoring out of the results the effect of known
Winter warming from large volcanic eruptions
An examination of the Northern Hemisphere winter surface temperature patterns after the 12 largest volcanic eruptions from 1883-1992 shows warming over Eurasia and North America and cooling over the
Global tracking of the SO2 clouds from the June
The explosive June 1991 eruptions of Mount Pinatubo produced the largest sulfur dioxide cloud detected by the Total Ozone Mapping Spectrometer (TOMS) during its 13 years of operation: approximately
Radiative forcing from the 1991 Mount Pinatubo volcanic eruption
Volcanic sulfate aerosols in the stratosphere produce significant long-term solar and infrared radiative perturbations in the Earth's atmosphere and at the surface, which cause a response of the
Tropical ozone loss following the eruption of Mt. Pinatubo
Total Ozone Mapping Spectrometer (TOMS) measurements of equatorial total ozone following the eruption of Mt. Pinatubo show a decrease of up to 6% over climatology. Ozone losses begin approximately a
Two‐dimensional simulation of Pinatubo aerosol and its effect on stratospheric ozone
This paper presents time-dependent simulations of the response of the stratosphere to the injection into the atmosphere of massive amounts of sulfur during the eruption of Mt. Pinatubo (The
Observations of the impact of volcanic activity on stratospheric chemistry
The basic stratospheric chemical and radiative processes which could be modified by volcanic injections to the stratosphere are reviewed. Observed effects after two major volcanic eruptions (El
Stratospheric Control of Climate
Firm evidence for a connection between variations in solar radiation and climate has been elusive. In his Perspective, Robock discusses the results of Haigh, who reports in this same issue (p. 981)
Climate model simulation of winter warming and summer cooling following the 1991 Mount Pinatubo volcanic eruption
We simulate climate change for the 2-year period following the eruption of Mount Pinatubo in the Philippines on June 15, 1991, with the ECHAM4 general circulation model (GCM). The model was forced by
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
