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. 

Was El Niño to blame for the above-average temperatures during November and December 2015?  As always, the answer is not that simple.  

This is a lab about evidence for past climate change as captured in ice sheets of Greenland and Antarctica. Students investigate climate changes going back thousands of years by graphing and analyzing ice core data from both Greenland and Antarctica. They use information about natural and human-caused changes in the atmosphere to formulate predictions about Earth's climate.
