Evidence from mountain glaciers does suggest increased glaciation in a number of widely spread regions outside Europe prior to the twentieth century, including AlaskaNew Zealand and Patagonia.
Discussion is okay, but the student understanding of the key concepts of this activity should also be measured using a questionnaire or by letting them interpret other data sets that they have not yet seen. The science background provided in the "Teachers Guide" could be used for students. If this is done, it would be important to have guiding questions to accompany the reading.
The Solar Activity graph is missing a units label on the left hand axis. It should be pointed out to students that the variations in tree growth is an indicator of climate change while the volcanic activity and sunspot activity are causes of climate change.
About the Science Comparison of different forcing mechanisms sunspots, volcanoes with one indicator for climate variability tree growth will foster the student understanding of complex interactions in climate system.
References are missing for some of the data. Some of the graphs are missing labels to say what the units being measured are. This is particularly a problem because the graphs contain two y-axes. Great scientific approach to have students synthesize information from three different data sources to draw conclusions about climate change.
If the volcanic ash stays in the troposphere, precipitation "washes it out" and its effect on climate is negligible. Only volcanic material that reaches the stratosphere will make a difference in the albedo of the atmosphere and have an effect on the climate.
However, educators probably need more in-depth information to handle various questions students may have. If the guide is not used, educators need to make sure that their students acquire this understanding in some other way.
Activity is a worksheet activity where students interpret data from graphs. Technical Details Very complete and directions are clear.The Little Ice Age was a period of regionally cold conditions between roughly AD and The term “Little Ice Age” is somewhat questionable, because there .

Little Ice Age Michael E Mann University of Virginia, Charlottesville, VA, USA The term Little Ice Age was originally coined by F Matthes in to describe the most recent year climatic. My position on the current global warming is the same as the overwhelming majority of international climate scientists: the current rate of global warming is unprecedented and is being caused by leslutinsduphoenix.com no way can my summary of the research regarding the impact of regional climate change on the Viking civilization and Europe during the Little Ice Age be used to "prove" the current global.
How the Little Ice Age affected South American climate For the first time, scientists reconstruct the rainfall distribution in Brazil during the climate changes that marked the Middle Ages using.
