Science Bulletins: Shrinking Glaciers—A Chronology of Climate Change

Analysis of Earth's geologic record can reveal how the climate has changed over time. Scientists in New Zealand are examining samples from the rocky landscape once dominated by glaciers. They are employing a new technique called surface exposure dating, which uses chemical analysis to determine how long minerals within rocks have been exposed to the air since the glaciers around them melted. Comparisons of this data with other climate records have revealed a link between glacial retreat and rising levels of carbon dioxide in the air, findings that are informing scientists' understanding of global climate change today.

Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History. Find out more about Science Bulletins at http://www.amnh.org/sciencebulletins/.

Climate Change – Wildlife & Wildlands

EPA partnered with National Oceanic and Atmospheric Administration, National Aeronautics and Space Administration, National Park Service,U.S. Fish and Wildlife Service, U.S. Forest Service, and Bureau of Land Management to produce a new educational kit, Climate Change, Wildlife, and Wildlands Toolkit for Formal and Informal Educators.The kit contains case studies, activities, and a video based on the highest quality climate science, environmental education and stewardship information, and is designed to educate, inspire, and engage students everywhere to become stewards of our nations wildlife and ecosystems.

Climate change and the melting glaciers in Switzerland – Docu – 2018

Climate change is causing glaciers to melt in Switzerland. In the summer of 2018, a mudflow has hit the village of Bondo in Switzerland. Climate change is in full swing. Can we still avert this or is climate change already too advanced so that we simply have to live with it? Are the melting glaciers in Switzerland one of the many consequences of climate change?

Climate change creates melting glaciers in Switzerland. We must quickly get a grip on global warming. According to the Indian writer Amitav Ghosh this is because we cannot imagine that our children will live in an unlivable world. Our endless desire for things like cars, meat and luxury goods are the main causes of the climate crisis. 'Everyone wants to be part of the good life', says Ghosh. "We are like a turkey for Thanksgiving. We are getting nicely stuffed but one day the head goes off. '

A mudflow from a melting glacier was the summer of the Swiss village of Bondo. Eight people died and the village was uninhabitable for months. Yet many do not want to see the consequences of the climate crisis. According to Ghosh, eating no meat or not driving is not enough to break the vicious circle. He thinks it is of the utmost importance that we oblige our authorities to take draconian measures and, if necessary, enforce them. It is ill to place all responsibility with the individual.

An example of enforcing government responsibility is the famous 'Climate case' that environmental organization Urgenda with lawyer Roger Cox brought against the Dutch State. Many legal procedures are now taking place worldwide. For example, a Peruvian mountain guide Saul Luciano Lliuya, whose village is also threatened by a melting glacier, has filed a lawsuit against the German RWE. The energy giant with its many coal-fired plants is responsible for 0.5% of global CO2 emissions. The Peruvian Lliuya states that RWE is also responsible for 0.5% of the damage that his village experiences. A German judge agreed with him and declared his request valid. A climate story about how we can turn the tide just in time.
