Paleoclimatology
Paleoclimatology is the study of changes in climate taken on the scale of the entire history of Earth. It uses a variety of proxy methods from the Earth and life sciences to obtain data previously preserved within rocks, sediments, ice sheets, tree rings, corals, shells and microfossils; it then...

Ocean
An ocean is a major body of saline water, and a principal component of the hydrosphere. Approximately 71% of the Earth's surface is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas.More than half of this area is over 3,000...

Global climate model
A General Circulation Model is a mathematical model of the general circulation of a planetary atmosphere or ocean and based on the Navier–Stokes equations on a rotating sphere with thermodynamic terms for various energy sources . These equations are the basis for complex computer programs commonly...

s to improve the representation of the present day climate, while investigating their response to climate forcing. The latest GISS GCM is called ModelE.

He is the co-author, with Joshua Wolfe, of Climate Change: Picturing the Science (2009), which has a foreword by Jeffrey D. Sachs. The book combines images of the effects of climate change with scientific explanations.

In October 2011, he was awarded the American Geophysical Union Climate Communications Prize for his work on communicating climate-change issues to the public. He is an ongoing contributor to the climate change blog, Real Climate.

The temperature record of the 2nd millennium describes the reconstruction of temperatures since 1000 CE on the Northern Hemisphere, later extended back to 1 CE and also to cover the southern hemisphere. A reconstruction is needed because a reliable surface temperature record exists only since about...

Ice core
An ice core is a core sample that is typically removed from an ice sheet, most commonly from the polar ice caps of Antarctica, Greenland or from high mountain glaciers elsewhere. As the ice forms from the incremental build up of annual layers of snow, lower layers are older than upper, and an ice...

Media and outreach

Schmidt is a founding member and contributor to RealClimate

RealClimate is a commentary site on climatology. The site's contributors are a group of climate scientists whose goal is to provide a quick response to developing stories and providing the context sometimes missing in mainstream commentary. The discussion is intended to be restricted to scientific...

, claim that Schmidt "runs" the RealClimate site, the site participants themselves state that all posts on the site are internally peer reviewed. Many are written by other members, with frequent guest posts from non-member leading scientists. Via the blog, Schmidt defended the scientists named in the 2009-2010 Climatic Research Unit emails controversy, including Michael E. Mann and Phil Jones, saying in a post on the blog, "Gravity isn't a useful theory because Newton was a nice man."
