On July 30, 2013, a weather station on the southwest coast of Greenland preliminarily set a new record high temperature for the country, but whether it will stand as an "official" record after scientists apply quality control procedures isn't yet known. What is known? Greenland's getting warmer.

Anthony Arguez, Normals Program Manager at NOAA’s National Climatic Data Center explains what scientists mean when they compare current weather conditions to “normal.”

Although they are related, meteorology and climatology have important differences, particularly in how scientists develop and use weather and climate models. What makes climatologists think they can project climate scenarios decades into the future when meteorologists cannot accurately predict weather more than two weeks in advance? This presentation by Wayne Higgins of NOAA's Climate Prediction Center clarifies the relationships and differences between weather and climate, as well as the differences between natural climate variability and human-induced climate change.

Starting in July, when you hear that a day was hotter, or colder, or rainier than normal, that normal will be a little different from what it was in the past.

Above-average sea surface temperatures, a natural cycle of increased hurricane activity, and a fading La Nina have influenced the 2011 Atlantic hurricane outlook.

Deep snow that fell across the Great Plains and the Northeast in late January and early February is the latest installment in the second very wintry winter in a row for the eastern U.S.

More than half of the United States experienced heat, drought, or flooding during 2011, demonstrating the power and momentum of climate extremes.

 Researchers at NOAA’s National Climatic Data Center collaborate with tropical cyclone centers and scientific agencies around the world to assemble and maintain the International Best Track Archive for Climate Stewardship (IBTrACS), an inventory of tropical cyclones.

This short animation helps demonstrate the difference between climate and weather by using the analogy of a leashed dog walking with a man.

This video explores what scientists know about how changes in global climate and increasing temperatures affect different extreme weather events.
