1. What do you notice? Summer temperatures n the Northern Hemisphena 1983-1993 4+ 18511680 Bae period More frequent Extremely cald Cold Normal In this Stats and Stories podcast, Sharon Hessney, the curator of \"What's Going On in This Graph?,\" describes the benefits of the Notice & Wonder approach: \"Noticing and wondering has a 'low floor and a high ceiling.' Every student can notice something in a graph. There are dots on it; it's about different countries. As they hear each other's noticings, they dig deeper. They'll discover more by comparing and contrasting aspects of the graph and by relating these noticings to the world they know.\" So, what can simply noticing look like in action? Here are examples of what students noticed about the above graph about summer temperatures in the Northern Hemisphere. I noticed that the graph is only focusing on the summer temperatures, and not the overall temperatures. The base year has a 29-year difference while the other years have a 10-year difference. The graph does not cover the years 1981-1982. Deija Robins from California I noticed that as the years go by, the mean or the center of the graph shifts farther to the right. This upward trend seems to be in a stage of rapid acceleration and [ wonder if it will continue to increase at the same rate in the coming years. Brooke Shalam from New York City I noticed that as the years went on the temperatures became hot and extremely hot more frequently. I also noticed that the distribution of the temperatures starts as an approximately symmetric distribution and becomes skewed right over the years. Chandler B from Georgia 3. Discuss. 2 b s ek et e e By e Where Are America's Winters Warming the Most? An essential part of our approach to teaching with graphs is that students don't do their thinking in a vacuum. On The Learning Network, moderators from the American Statistical Association provide students with feedback on their comments. Plus, students get to read what others have to say, and have a chance to reply as well whether they are in the same classroom or on the other side of the globe. In the screen shot below, you can see a student, Madison from New Jersey, responding to Christian in Pittsburgh. One of the questions Madison asks is, \"Are these the effects of naturally increasing temperatures, or the doing of man made emissions?\" Melting Ice Minimum Sea Ice Extent in the Arctic Million sq. km Arctic sea ice extent 19790 12016 . 2017 70 O 5 4 Lowest extent 1979 '81 '83 '85 '87 '89 '93 95 97 99 01 103 5 107 109 11 13 15 17 We Charted Arctic Sea Ice for Nearly Every Day Since 1979. You'll See a Trend. | Arctic sea ice has been in a steep decline since scientists started using satellites to measure it 40 years ago. And the 10 lowest ice extents have all been recorded since 2007. Change in Greenland Ice Sheet mass No change since 2002, in billions of metric tons -1,030 billion metric tons -2,000 -. -3,000 - 2002 105 10 "15 2017 Source: The European Space Agency Climate Change Initiative As Greenland Melts, Where's the Water Going? | Each year, Greenland loses 270 billion tons of ice as the planet warms. New research shows that some of the water may be trapped in the ice sheet, which could change how scientists think about global sea levels.Changing Ocean Temperature The Oceans Are Heating Up Data since the 1940s shows that the heat content of the oceans has been increasing. Waters closest to the surface have warmed significantly over the past two decades. Shallower ocean or warming Deeper ocean warming Units of energy relative to 2006-2015 average 1940 1960 1980 2000 2018 Note: Shallower ocean warming describes depths between 0 and 700 meters. Deeper ocean warming is between 700 and 2,000 meters. By The New York Times | Source: Lijing Cheng et al., Institute of Atmospheric Physics, Beijing Ocean Warming Is Accelerating Faster Than Thought, New Research Finds | An analysis concluded that Earth's oceans are heating up 40 percent faster on average than a United Nations panel estimated five years ago, a finding with dire implications for climate change.
