Anthropogenic climate change is one of the, if not the most, pressing issues of our times. The problems that it causes range across many social and environmental domains from habitat and species loss and displacement to the more human and social concerns and issues of access to water, sea level rise that affects coastal communities, to economic degradation as a result of the aforementioned and other connected issues such as increased frequency of storms, droughts, wildfires, and the like. We also know that the affects of climate change are not distributed evenly across populations- that many will and do feel the negative effects of this slow developing problem earlier and more intensely than others based on where they are located both geographically and within economic and other socio-cultural hierarchies. We also know that recently, there is a marked effort to begin to move away from simply decrying the horrors of climate change to a continued recognition of those horrors as they exist now and into the future alongside attempts to begin to come to terms with the changing climate and to rethink the ways that our social and environmental relations and communities are organized with an eye toward both adapting to these changes and mitigating further damage. There is, however, much work to be done. This book was co-authored by undergraduate students at Worcester Polytechnic Institute while exploring the influences of Earth systems and human systems on climate change and the communities at most risk in an interdisciplinary project-based first year course. This course attempts to bring together knowledge of the science of ecological and climate systems and their changing status with knowledge of the social and communal structures within which these systems are embedded and through which they have been influenced. The book highlights key interests and insights of current students in their quest to think through these issues and to create a better world.

This video offers the audience a specific definition of the term 'global climate models'. It highlights and defines key climate modeling concepts such as the physics of fluids, carbon, nitrogen and water cycles, paleo climate data vs current and projected data vs predictive and real data.

When water utility personnel recognized their groundwater withdrawals were damaging ecosystems in the Tampa Bay area, they found new ways to reduce their dependence on it.

This course introduces students to climate studies, including beginnings of the solar system, time scales, and climate in human history. It is offered to both undergraduate and graduate students with different requirements.

This short, animated video describes what is meant by climate, its characteristics, and the range of impacts due to climate change. The difference between mitigation and adaptation is also discussed.

In this video segment adapted from NOVA: Becoming Human, learn how the analysis of rock layers and ocean sediments supports the theory that rapid climate change may have jump-started human evolution two million years ago.

Introduction:
Groundwater is key to Texas future and economy. The resource has long been a focus of legislative and economic interest. In the earliest days, the resource was viewed as 'occult and hidden.' That sense of mystery remains even as groundwater becomes more critical to the water resource picture for the state.
Since 1951, the state conducts regional water planning with the involvement of citizen stakeholders. Let's use your science-based knowledge of groundwater flow to see if you can find the right balance for both protecting and planning for groundwater use.
Our Case:
This week we will evaluate a historic court case from June 13, 1904. The case of East versus Texas Central Railroad Company is the Texas Supreme Ruling that provides the foundation for Texas groundwater law -- Rule of Capture.
In the appendix, you will find the following figures to help you determine whether or not Mr. East's well was impacted by the railroad company's pumping:

Platt map showing well locations and possible distances
Schematics of the well dimensions, along with simplified subsurface geology in the area.

In addition, you will be interested in knowing that the Geologic Atlas of Texas shows that the wells were likely completed in the Pawpaw Formation, which is a thick calcareous clay unit in the lower sections and cemented sand in the upper part. Lithologies in the area are reported to yield limited to moderate amounts of water in shallow wells. You can expect that the formation was an unconfined unit and assume that the East well is down-gradient from the Railroad well.
Assignment Part One:

1. Using the information from our last lecture, what do you think a reasonable transmissivity rate might be for the Pawpaw formation?

a. Estimate a transmissvity for a cemented sand unit.
b. Use this value as your first estimate in calculations to calculate the potential drawdown with Jacob's equation. This calculates the drawdown in an nonleaky artesian aquifer, sa, given the observed water table drawdowns.

sa = swt -- (s2st/2m)

c. Calculate swt using a correction equation.

Swt = m-(m2-2msa)1/2

Where m is the initial saturated thickness, which you may estimate at 30 ft.

2. How much water do you estimate that the railroad can extract before the well is impacted? Complete a diagram showing estimated drawdown (ft) on the y-axis and distances from the Railroad well (ft) using different transmissivity values and different distances. What do you discover about the case?
3. With your hydrogeologic analysis, do you believe that the East well was impacted by the railroad well? Can you explain how significant the impact may or may not have been?

Climate Considerations:
Is it possible that climate conditions could have impacted conditions in the well? Visit the Greenleaf website ([greenleaf.unl.edu/downloads/scPDSI.zip]) and access data for Palmer Drought Severity Indices. Looking at this data, complete the next questions.
Assignment Part 2:

4. Looking at the drought severity index maps of Texas from October 1900 to September 1902. What kind of implications might climate conditions have had on the groundwater conditions?
5. If climate conditions worsened, what do you think would happen to the wells?

In these math problems, students will examine the characteristics of water droplets in clouds.

In this scenario-based, problem-based learning (PBL) activity, students investigate cloud formation, cloud classification, and the role of clouds in heating and cooling the Earth; how to interpret TRMM (Tropical Rainfall Measuring Mission) images and data; and the role clouds play in the Earth’s radiant budget and climate. Students assume the role of weather interns in a state climatology office and assist a frustrated student in a homework assignment. Learning is supported by a cloud in a bottle and an ice-albedo demonstration, a three-day cloud monitoring outdoor activity, and student journal assignments. The hands-on activities require two 2-liter soda bottles, an infrared heat lamp, and two thermometers. The resource includes a teacher's guide, questions and answer key, assessment rubric, glossary, and an appendix with information supporting PBL in the classroom.

Most students understand that water quality is an important issue, however many do not understand the complexity associated with the processes involved, the complex nature of estuarine systems, or the fact that management decisions are made based on available data sets that can be difficult at best to interpret. Students will be provided nutrient data in Excel for two Texas estuaries which they will supplement with additional information that they have compiled on these two estuaries during the duration of the course through a GIS database available to the entire class. Furthermore, students will retrieve information from the WWW to learn more about the specific estuaries and the nutrients of interest and their impacts on the environment.
