Global Climate Change

(View Complete Item Description)

Paul Andersen explains how the climate on the earth is affected by the amount of solar radiation and the greenhouse affect. The addition of anthropogenic greenhouse gases has led to global warming which is impacting humans on the planet. A discussion of the greenhouse effect and greenhouse gases (including water vapor, carbon dioxide, methane, nitrous oxide, and CFCs) is included. Countries have committed to reduce through both the Kyoto Protocol and the Paris Agreement.

The Impact of Ocean Acidification on Marine Ecosystems

(View Complete Item Description)

The main content objectives covered in this unit are the phenomena of global warming, carbon cycle, ocean acidification, and its impact on plants, animals, and the marine ecosystem. The main purpose of this is to provide the reader with the basic knowledge base about these processes and understand the main players that are responsible for them. Fossil fuel pollution by human activities is contributing to the increase in the amount of CO2 in the atmosphere. Some of the CO2 is being absorbed by the oceans. This process increases the number of free hydrogen ions in the oceans, making the ocean water more acidic. This phenomenon is called ocean acidification. When oceans become acidic, they can negatively affect the plants, living organisms such as shell-forming organisms, and other marine life. The results of this process are devastating and this unit hopes to bring students’ attention to these dangers.

An Introduction to Global Health - Climate Change and Health (18:01)

(View Complete Item Description)

Our planet is currently being challenged by dramatic changes to earth and human systems under the influence of climate change and variability. These include changes of population and environmental dynamics that impacts human health. Thus, climate change is considered the biggest threat to human health in the 21st century. Health impacts can be direct typically related to extreme weather events; indirect with linkages to climate change induced environmental alterations and damage or in relation to displacement, conflict and social disruption. This presentation provides a series of examples of changes of environmental and social determinants of health with negative or positive health impacts. These include impacts on communicable diseases, non-communicable diseases and mental health of importance in particular in vulnerable urban and rural settings as well as among sensitive community groups exposed to variations in temperature and precipitation patterns.

Investigating Climate Change Using Observed Temperature Data

(View Complete Item Description)

In this activity, students download historic temperature datasets and then graph and compare with different locations. As an extension, students can download and examine data sets for other sites to compare the variability of changes at different distinct locations, and it is at this stage where learning can be individualized and very meaningful.
