This video features scientists in New Zealand's Southern Alps, examining samples from the rocky landscape once dominated by glaciers. Their research, combined with other climate records, has revealed a link between glacial retreat and rising levels of carbon dioxide in the air.

Our bodies are finely-calibrated, organic machines that are capable of dealing with the fluctuations of our internal systems in response to stimuli. We are able to regulate these changes through feedback loops in order to maintain the self in a prime ‘operating condition’ known as homeostasis. While deviations from homeostasis may occur, the body has processes in place to eventually return to normal. Long term or highly disruptive deviation, to the point where the body’s natural feedback loops are insufficient at correcting the error, is an indicator of something abnormal at work—be it parasite, virus, or organ malfunction.

The Earth also displays similar mechanisms of homeostasis—complex feedback loops that allow it to regulate temperature, gas concentrations, and pH. Normally, small fluctuations are regulated within the system. Negative feedback loops maintain balance through chemical processes like the sink and release of carbon gases. However, as excessive fossil fuel combustion tips the scales, it is likely that we are moving further away from the point where these feedback loops are enough to return the carbon cycle to balance.

We can see symptoms of this deviation in alteration of the climate, increased warming, and the thawing of glaciers and permafrost. The study of these indicators allow us to monitor the disease and provide insight into the underlying cause. The feedback loops found in the carbon cycle are unable to rectify the anthropogenic carbon output post Industrial revolution, leading to some alarming trends. The greater the divergence from normal the greater the impact these indicators have on the system of the planet until, like the human body, there is irreparable harm to the system.

Is this warming a fever-- a planetary self-preservation system precipitated by the intemperate combustion of fossil fuels-- that aims to overcorrect the problem before returning to homeostasis in the geological timeline? How does a ‘sick’ planet impact our own health? This unit addresses the consequence of anthropogenic carbon sourced global warming on the planetary system and human physiology.

In this activity, students engage in a simulation of the international negotiation process in order to convey how the international community is responding to climate change. Participants learn firsthand about the interests of different countries and the range of policy responses to mitigate future climate change.

This lesson has activities where students will learn about buoyancy and explore how hot water rises and cold water sinks. As an extension and real-life application, students will see that glacial run-off is occurring at a rapid pace and the cold glacial water could potentially change ocean currents thus influencing global climates.

This is an interactive map of California and the Sierra Nevada mountains, showing how the amount of water stored in the snowpack will vary under different climate scenarios. The tool shows observations and projections from 1950 to 2090, and uses low or high emission scenarios to model future snowpack. The tool can be adjusted to show different months of the year and various climate models, graphed by site.

Student teams design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy. In this activity, students gain a better understanding of the three different types of heat transfer, each of which plays a role in the solar water heater design. Once the model devices are constructed, students perform efficiency calculations and compare designs.

This video discusses two key signs of global change in the Southern Ocean: changes in Antarctic bottom water and ocean acidification.

This is a team-based activity that teaches students about the scale of the greenhouse gas problem and the technologies that already exist which can dramatically reduce carbon emissions. Students select carbon-cutting strategies to construct a carbon mitigation profile, filling the the wedges of a climate stabilization triangle.

In this activity, students calculate electricity use by state and determine, using Google Earth, how much land would be required to replace all sources of electricity with solar panels.

In this activity, learners use Google Earth to calculate electricity use by state and determine how much land would be required to replace all sources of electricity with solar panels. They also consider costs and land-use trade-offs.

Through the innovative use of a collection of tools, Maryland has begun identifying which of its roads and bridges are vulnerable to climate-related events.

This short video clip summarizes NOAA's annual State of the Climate Report for 2009. It presents a comprehensive summary of Earth's climate in 2009 and establishes the last decade as the warmest on record. Reduced extent of Arctic sea ice, glacier volume, and snow cover reflect the effects of rising global temperature.

In this short activity, students create a timeline of climate science over the past 200 years and gather information from a U.S. Forest Service video about mitigation and adaptation strategies undertaken by the Service to address climate change in national forests.

This short cartoon video uses a simple baseball analogy (steroid use increases probability of hitting home runs) to explain how small increases in greenhouse gases can cause global temperature changes and increase the probability of extreme weather events.

This course will provide you with skills to overcome barriers to action, mobilize knowledge and data effectively, and work across silos in genuine interdisciplinary and collaborative practice. You’ll learn how to lead or participate in community engagement, without triggering fear and overwhelming others; practise critical self-awareness and self-reflection; and consider equity-based and decolonizing approaches.

This course is designed for professionals looking to advance the intersecting work of climate action and adaptation, including planners, engineers, elected officials and community leaders. You will leave with practical and relevant skills to lead, accelerate and participate in the essential work of climate adaptation in your organization and community.

LEARNING OUTCOMES
By the end of the course, you will be able to do the following:

• Describe the dynamics of collaborative, team-based planning processes
• Apply key concepts in climate communications and knowledge mobilization
• Engage in meaningful dialogue with internal and external stakeholders
• Develop adaptive and responsive strategies for working in complex systems
• Analyze and overcome internal and external barriers to climate adaptation

In this activity, students research various topics about ocean health, e.g. overfishing, habitat destruction, invasive species, climate change, pollution, and ocean acidification. An optional extension activity has them creating an aquatic biosphere in a bottle experiment in which they can manipulate variables.

This NASA video reviews the role of the sun in driving the climate system. It uses colorful animations to illustrate Earth's energy balance and how increased greenhouse gases are creating an imbalance in the energy budget, leading to warming. The video also reviews how the NASA satellite program collects data on the sun.

A short video on how changing climate is impacting the ecosystem and thereby impacting traditional lifestyles of the Athabaskan people of Alaska.

This video provides an overview of how computer models work. It explains the process of data assimilation, which is necessary to ensure that models are tied to reality. The video includes a discussion of weather models using the Goddard Earth Observing System (GEOS-5) model and climate models using the MERRA (Modern Era Retrospective Analysis for Research and Applications) technique.

Changing ocean chemistry could have a disastrous impact on shellfish and fisheries in Puget Sound. The Suquamish Tribe is working with partners to inform the public about this problem while they elicit support for research and monitoring the issue.
