Is El Niño the Marcia Brady of climate variability? In this week's Beyond the Data blog, Jake Crouch talks about whether El Niño played a starring role in this winter's climate.

In this week's Beyond the Data blog, NCEI's Deke Arndt explains how comparing a record-setting warm streak from 2015 to one in 1944 is like comparing the tallest player in the NBA to the tallest kid in 2nd grade.

In the midst of the mega snowstorm bearing down on the East, NCEI's Deke Arndt looks longingly back at December's warmth in his latest Beyond the Data blog. 

This week, Beyond the Data looks at one of the more well-grounded “rules of thumb” for understanding climate change: cooler "things" are warming more quickly than warmer things.

For those who are still waiting for winter's first snow, Deke Arndt blogs about using historical climate data to ballpark when it might arrive. 

This week's bloggers use the historical record to generate 10,000 possible scenarios for the remainder of 2015. In 97% of them, 2015 sets a new record temperature.

In this activity students work with data to analyze local and global temperature anomaly data to look for warming trends. The activity focuses on the Great Lakes area.

This animation shows the warming of Earth's surface temperature from 1870-2100 based on results from the NCAR Community Climate System Model.

Two short, narrated animations about carbon dioxide and Earth's temperature are presented on this webpage. The first animation shows the rise in atmospheric CO2 levels, human carbon emissions, and global temperature rise of the past 1,000 years; the second shows changes in the level of CO2 from 800,000 years ago to the present.

In this activity, students use maps and data to learn about where and how hurricanes form and possible correlations with climate change affecting their strength.
