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 …

The deliberate injection of particles into the stratosphere has been suggested as a possible
geoengineering scheme to mitigate the global warming aspect of climate change. Injected …

The growing problem of changing environmental conditions caused by climate
destabilization is well recognized as one of the defining issues of our time. The root problem …

We use a global climate model to compare the effectiveness of many climate forcing agents
for producing climate change. We find a substantial range in the “efficacy” of different …

We describe the construction of a continuous 38-year record of stratospheric aerosol optical
properties. The Global Space-based Stratospheric Aerosol Climatology, or GloSSAC …

We describe the current GISS analysis of surface temperature change for the period 1880–
1999 based primarily on meteorological station measurements. The global surface …

A previous model intercomparison of the Tambora aerosol cloud has highlighted substantial
differences among simulated volcanic aerosol properties in the pre-industrial stratosphere …

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 …

Vertical profiles of size‐resolved aerosol concentrations above Laramie, Wyoming (41° N),
have been measured for the past thirty years, 1971‐2001. During this period, two somewhat …

We define the radiative forcings used in climate simulations with the SI2000 version of the
Goddard Institute for Space Studies (GISS) global climate model. These include temporal …
