evidence: Providing reliable and quality climate information allows government agencies, researchers, and others to make informed decisions that can save lives and improve quality of life. Since the late 1990s, NCEI has provided a suite of climate services, including the monthly Global Climate Report, to support this mission. One of its most highly visible and widely used products is NOAA’s global surface temperature dataset (also known as NOAAGlobalTemp), which is an authoritative dataset used to assess observed global climate change. [...] The Arctic is the fastest-warming region in the world, warming at least three times faster than any other region on Earth. The exclusion of this region in previous versions of NOAAGlobalTemp resulted in a very slight cold bias in the global average, particularly in recent years.
