Global gridded data set of the oxygen isotopic composition in seawater
[1] We present a new 3-dimensional 1° × 1° gridded data set for the annual mean seawater oxygen isotope ratio (δ18O) to use in oceanographic and paleoceanographic applications. It is constructed fromExpand

Efficacy of climate forcings
[1] 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 forcings, whereExpand

Improved Attribution of Climate Forcing to Emissions
All Together Now Deciding how to change emissions of polluting gases that affect climate through their radiative forcing properties requires that the quantitative impact of these emissions beExpand

Earth's Energy Imbalance: Confirmation and Implications
Our climate model, driven mainly by increasing human-made greenhouse gases and aerosols, among other forcings, calculates that Earth is now absorbing 0.85 ± 0.15 watts per square meter more energyExpand

Solar Forcing of Regional Climate Change During the Maunder Minimum
We examine the climate response to solar irradiance changes between the late 17th-century Maunder Minimum and the late 18th century. Global average temperature changes are small (about 0.3° to 0.4°C)Expand

Present-Day Atmospheric Simulations Using GISS ModelE: Comparison to In Situ, Satellite, and Reanalysis Data
Abstract A full description of the ModelE version of the Goddard Institute for Space Studies (GISS) atmospheric general circulation model (GCM) and results are presented for present-day climateExpand

Forced annular variations in the 20th century Intergovernmental Panel on Climate Change Fourth Assessment Report models
[1] We examine the annular mode within each hemisphere (defined here as the leading empirical orthogonal function and principal component of hemispheric sea level pressure) as simulated by theExpand

Rapid early Holocene deglaciation of the Laurentide ice sheet
The demise of the Laurentide ice sheet during the early Holocene epoch is the most recent and best constrained disappearance of a large ice sheet in the Northern Hemisphere, and thus allows anExpand

Consistent simulations of multiple proxy responses to an abrupt climate change event.
Isotope, aerosol, and methane records document an abrupt cooling event across the Northern Hemisphere at 8.2 kiloyears before present (kyr), while separate geologic lines of evidence document theExpand
