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 …

We review the major impact‐associated mechanisms proposed to cause extinctions at the
Cretaceous‐Tertiary geological boundary. We then discuss how the proposed extinction …

Knowledge of the frequencies of highly explosive, moderately explosive, and nonexplosive
eruptions would be useful in a variety of volcano studies. Historical records are generally …

The evidence for the Little Ice Age, the most important fluctuation in global climate in
historical times, is most dramatically represented by the advance of mountain glaciers in the …

A global stratospheric aerosol database employed for climate simulations is described. For
the period 1883–1990, aerosol optical depths are estimated from optical extinction data …

The potential global atmospheric and climatic consequences of nuclear war are investigated
using models previously developed to study the effects of volcanic eruptions. Although the …

We use a three‐dimensional climate model, the Goddard Institute for Space Studies (GISS)
model II with 8° by 10° horizontal resolution, to simulate the global climate effects of time …

The risks of global warming are pressing and potentially vast. The difficulty of doing without
fossil fuels is daunting, possibly even insurmountable. So there is an urgent need to rethink …

The deuterium-hydrogen abundance ratio in the Venus atmosphere was measured while
the inlets to the Pioneer Venus large probe mass spectrometer were coated with sulfuric …

Radiative transfer calculations are performed for volcanic ash clouds assumed to consist of
mixtures of ash particles, ice spheres, water droplets and ash particles coated with sulphuric …
