Climate experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) will announce new data on 2013 global temperatures during a media teleconference at 1:30 p.m. EST Tuesday, Jan. 21.

The scientists also will discuss 2013's most important weather and climate events. NASA and NOAA are two keepers of the world's temperature data and independently produce a record of Earth's surface temperatures and changes based on historical observations over oceans and land.

Consistency between the two independent analyses, as well as analyses produced by other countries, increases confidence in the accuracy of such data, the assessment of the data, and resulting conclusions. These analyses provide government and business leaders with critical information about climate change.

The NASA and NOAA 2013 global temperature analyses will be issued in a news release 90 minutes before the start of the teleconference.

The teleconference panelists are:

-- Gavin Schmidt, deputy director, NASA's Goddard Institute for Space Studies, New York

-- Thomas R. Karl, director, NOAA's National Climatic Data Center, Asheville, N.C. and chair of the Subcommittee on Global Change Research

Media can participate in the teleconference by calling 888-810-6809 (toll-free in U.S./Canada) or 1-212-519-0808 (international) and using the passcode "climate." The briefing also will be streamed live at:
