Work

He was educated at The Corsham School, earned a BA (Hons) in mathematics at Jesus College, Oxford, and a PhD in applied mathematics at University College London. [3] Schmidt worked on the variability of the ocean circulation and climate, using general circulation models (GCMs). He has also worked on ways to reconcile paleo-data with models. He helped develop the GISS ocean and coupled GCMs to improve the representation of the present day climate, while investigating their response to climate forcing. [4]

As of 2024, Schmidt heads NASA's Goddard Institute for Space Studies. [5] He was named for the director position in June 2014 as its then deputy director, becoming to the third person to hold this post, which had been vacant after the retirement of James E. Hansen. [6] In an interview with Science News, Schmidt said that he wanted to continue the institute's work on climate modeling and to expand its work on climate impacts and astrobiology. [7]

Research

His main research interest is climate variability, both its internal and the response to climate forcing, investigated via ocean-atmosphere general circulation models. He also uses these to study palaeoclimate by working on methods to compare palaeo-data with model output. Schmidt helps to develop the GISS ocean and coupled GCMs (ModelE). This model has been "isotopically enabled" to carry oxygen-18 tracers, allowing the model to simulate the pattern of δ18O observed in ice cores, cave records and ocean sediments. [2]

Media and outreach

Schmidt has appeared on various occasions in the media, often he is asked about his expertise on climate related study findings, current events or gives lectures. [2] Schmidt worked with the American Museum of Natural History, the College de France, and the New York Academy of Sciences for education and outreach. [3] Schmidt and eight other colleagues founded in 2004 the RealClimate blog. The blog provides critical commentary on climate science with the scope on outreach to the public and for journalists. [2] [8] Additionally, the blog features frequent guest posts by experts in their field. Articles and commentary have defended scientific research against allegations made about the hockey stick graph. [9] During the 2009-2010 Climatic Research Unit email controversy, he strongly defended the scientists involved, including Michael E. Mann and Phil Jones. Journalist Fred Pearce noted, "Schmidt wrote that the emails merely showed how scientists interact in private", and that "Gravity isn't a useful theory because Newton was a nice man." [10]

Schmidt was EarthSky Science Communicator of the Year in 2011. [11]

Awards

In 2011, the American Geophysical Union awarded Schmidt the inaugural Climate Communications Prize, for his work on communicating climate-change issues to the public. The award news release noted his outreach work including co-founding and contributing to the RealClimate blog. [12] [13] He was a contributing author [14] of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC); the work of the IPCC, including the contributions of many scientists, was recognised by the joint award of the 2007 Nobel Peace Prize. Schmidt was named as one of Scientific American's "Top 50 Research Leaders" of the year 2004. [15]

Publications

Schmidt has published over 100 studies in peer-reviewed journals such as Proceedings of the National Academy of Sciences , Science , and Nature , on various climate related topics. [3] [16]

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. [17]

His Erdős number is four. [18]

<span class="mw-page-title-main">Climate</span> Statistics of weather conditions in a given region over long periods

Climate is the long-term weather pattern in a region, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude, longitude, terrain, altitude, land use and nearby water bodies and their currents.

<span class="mw-page-title-main">Climate model</span> Quantitative methods used to simulate climate

Numerical climate models are mathematical models that can simulate the interactions of important drivers of climate. These drivers are the atmosphere, oceans, land surface and ice. Scientists use climate models to study the dynamics of the climate system and to make projections of future climate and of climate change. Climate models can also be qualitative models and contain narratives, largely descriptive, of possible futures.

<span class="mw-page-title-main">General circulation model</span> Type of climate model

A general circulation model (GCM) is a type of climate model. It employs a mathematical model of the general circulation of a planetary atmosphere or ocean. It uses the Navier–Stokes equations on a rotating sphere with thermodynamic terms for various energy sources. These equations are the basis for computer programs used to simulate the Earth's atmosphere or oceans. Atmospheric and oceanic GCMs are key components along with sea ice and land-surface components.

<span class="mw-page-title-main">Instrumental temperature record</span> Direct measurements of the Earths temperature

The instrumental temperature record is a record of temperatures within Earth's climate based on direct measurement of air temperature and ocean temperature. Instrumental temperature records do not use indirect reconstructions using climate proxy data such as from tree rings and marine sediments. Instead, data is collected from thousands of meteorological stations, buoys and ships around the globe. Areas that are densely populated tend to have a high density of measurement points. In contrast, temperature observations are more spread out in sparsely populated areas such as polar regions and deserts, as well as in many regions of Africa and South America. In the past, thermometers were read manually to record temperatures. Nowadays, measurements are usually connected with electronic sensors which transmit data automatically. Surface temperature data is usually presented as anomalies rather than as absolute values. A temperature anomaly is presented compared to a reference value, also called baseline period or long-term average, usually a period of 30 years. For example, a commonly used baseline period is the time period from 1951 to 1980.
