Explore the future through modeling, reading, and discussion in an open-ended seminar! Our fields of interest will include changes in science and technology, culture and lifestyles, and dominant paradigms and societies.

Think science has all the answers? Think again. This course will use real, authentic data to explore and investigate modern controversies in Earth Sciences. Use tide gauge records to understand how countries around the world attempt to protect themselves from tsunami events. Process seismic data to predict earthquake recurrence in the New Madrid seismic zone, right here in the breadbasket of the US. Sort through the millions of years of the geologic timeline to shed some light on what actually did, and did not, kill the dinosaurs. Finally, use global atmospheric data to understand how misrepresentation of data can be used to paint a distorted view of past, present, and future climate.

Conversations host Harry Kreisler welcomes Yale Professor James Gustave Speth for a discussion of his career in the environmental movement. Professor Speth traces his changing perspective on the appropriate response to the environmental crisis. Concluding that only a radical transformation of capitalism will save the planet for future generations, he outlines the changes in consciousness and in the political agenda that will be required.

Students learn about using renewable energy from the Sun for heating and cooking as they build and compare the performance of four solar cooker designs. They explore the concepts of insulation, reflection, absorption, conduction and convection.

Students will really warm up to this lesson about global warming as they study multimedia materials and use a variety of comprehension strategies.

D-Lab: Water, Climate Change, and Health is a project-based, experiential, and transdisciplinary course. Together with peers and experts, we will explore the vitally important interface of water, climate change, and health. This course addresses mitigation and adaptation to climate change as it pertains to water and health. Water-borne illness, malnutrition, and vector-borne diseases represent the top three causes of morbidity and mortality in regions of our focus. Students submit a term project, setting the stage for a lifelong commitment to communicating climate science to a broad public.

In recent years, the redistribution of risk has created conditions for natural and technological disasters to become more widespread, more difficult to manage, and more discriminatory in their effects. Policy and planning decision-makers frequently focus on the impact that human settlement patterns, land use decisions, and risky technologies can have on vulnerable populations. However, to ensure safety and promote equity, they also must be familiar with the social and political dynamics that are present at each stage of the disaster management cycle. Therefore, this course will provide students with:

An understanding of the breadth of factors that give rise to disaster vulnerability; and
A foundation for assessing and managing the social and political processes associated with disaster policy and planning.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Dimethyl sulfide (DMS) is a gas produced by bacteria and algae that gives the ocean its distinctive scent. It also plays an important role in cloud formation, leading scientists to think its production may be instrumental in regulating climate change. But sea ice melt in the polar oceans under global warming has led to a reduction in DMS production, which may further intensify climate warming. To gain a better understanding of how bacteria contribute to DMS production, scientists recently investigated the distribution of bacterial genes involved in DMS cycling in seawater samples collected from around the world. They found evidence that intense DMS cycling facilitated predominantly by Alphaproteobacteria and Gammaproteobacteria occurs in the Arctic and Antarctic oceans, with high involvement of the enzymes DMSP demethylase, DMSP lyases, and trimethylamine monooxygenase..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

CK-12 Earth Science For High School covers the study of Earth - its minerals and energy resources, processes inside and on its surface, its past, water, weather and climate, the environment and human actions, and astronomy.

CK-12 Earth Science For Middle School covers the study of Earth - its minerals and energy resources, processes inside and on its surface, its past, water, weather and climate, the environment and human actions, and astronomy.

Students learn how rooftop gardens help the environment and the lives of people, especially in urban areas. They gain an understanding of how plants reduce the urban heat island effect, improve air quality, provide agriculture space, reduce energy consumption and increase the aesthetic quality of cities. This draws upon the science of heat transfer (conduction, convection, radiation, materials, color) and ecology (plants, shade, carbon dioxide, photosynthesis), and the engineering requirements for rooftop gardens. In the associated activity, students apply their scientific knowledge to model and measure the effects of green roofs.

El Niño is marked by the appearance from time to time of warm water in the central and eastern Pacific Ocean. The end result of the evaporative process that follows is excessive rainfall.
