Deke Arndt, Chief of the National Climatic Data Center’s Climate Monitoring Branch, uses a football field to explain how NOAA creates its Climate Extremes Index.

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

In 2011, La Niña and the Pacific Decadal Oscillation cooled parts of the Pacific Ocean, but unusually warm temperatures predominated elsewhere.

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.

This year’s Arctic Report Card emphasizes that climate change is more prominent in the Arctic than at lower latitudes.

For decades, the City of Boulder, Colorado, has been successfully managing its water supply despite the challenges of being located in a semi-arid climate. But a local water manager wonders if climate change will change the rules of the game...

Curiosity is a cruel master, says Dave Bertelsen. Over the past 25 years, he has hiked over 12,000 miles through a desert canyon, just to see what was blooming. He found a few surprises along the way.

 The Sun is the main source of power for the Earth's climate machine. Space-based measurements, begun in 1978, indicate Earth receives an average of 1,361 W/m<sup>2</sup> of incoming sunlight, and the amount varies by about one-tenth of a percent over the course of the 11-year solar cycle. 

This webinar will examine how variations in the tropical Pacific can affect high-latitude regions such as Alaska.

Pacific Islands Climate Education Partnership

This partnership has developed a detailed strategic plan to collaboratively improve climate knowledge among the region’s students and citizens in ways that exemplify modern science and indigenous environmental knowledge, address the urgency of climate change impacts, and honor indigenous cultures.
