Introduction
Today’s generation of climate models are typically run at resolutions that cover the globe with a 256 by 128 longitude/latitude horizontal grid or about a 1.4 degree latitude-longitude grid at the equator.
An experimental version of the CCSM CAM3 was run at a resolution much more similar to a global numerical weather prediction model (1024×512 grid [...]
NOAA’s National Climatic Data Center archives and analyzes weather data from around the world. This animation shows how the average global temperature has changed over the past 150 years. “Cool colors” (blue and green) indicate temperatures warmer than was it considered average; “hot colors” (orange and red) are warmer than average.

The Earth is a complex system with a unique climate.
Many scientists are concerned that Earths climate is changing at an unprecedented rate.
Each January, scientists at NASA Goddard Institute for Space Studies release temperature data for the previous year.
How do scientists study how warm our home planet is, and how do they determine what factors affect [...]
The worlds ocean surface temperature was the warmest for any August on record, and the warmest on record averaged for any June-August summer season, according to NOAAs National Climatic Data Center in Asheville, N.C. World-wide records began in 1880. Shown here is a visualization of the August global temperature anomalies–or in other words, how the [...]
The NOAA polar-orbiting satellites (POES) have been collecting sea surface temperature data for over 22 years. This animation is a compilation of that data from January 1985 – January 2007. Of note are the changes in the Gulf Stream, El Nino and La Nina cycles in the Pacific, and the seansonal changes in [...]
Satellites have been observing ocean temperatures long enough so that we can understand how temperatures change on average over a long period of time–otherwise known as climate. Shown here is the temperature of the ocean over one year, averaged from 1985-2008. The data repeats so you can see annual changes all over the [...]

Each year, scientists at NASA Goddard Institute for Space Studies analyze global temperature data.
A rapid warming trend has occurred over the past 30 years. Calendar year 2008 was the coolest year since 2000, according to the Goddard Institute for Space Studies analysis [...]
