The course starts with an introduction to the climate, highlighting it as a combination of natural and human-made (anthropogenic) phenomena.

The Greenhouse Effect: 

It's explained that the Earth's climate, including temperature, wind, humidity, and precipitation, is significantly influenced by the greenhouse effect. This process involves certain gases absorbing infrared radiation from the Earth's surface and reradiating it in all directions, which keeps the planet habitable by making it warmer than it would otherwise be.

Astrophysical and Geophysical Influences: 

The course covers how astrophysical phenomena, particularly the Milankovitch Cycles (eccentricity, obliquity, and precession), alongside natural geophysical factors like volcanic eruptions and continental drift, play crucial roles in shaping the Earth's climate.

Definition and History of Climate Change: 

Climate change is defined as long-term changes in the mean and variability of climatic properties. The Earth's climate has undergone numerous changes, with seven glacial advances and retreats in the last 650,000 years. The last ice age ended approximately 11,000 years ago, marking the beginning of the modern climate era.

Modern Climate Change: 

Unlike historical climate fluctuations, modern climate change, marked by significant global warming since the onset of the industrial era, is occurring at an unprecedented pace. This recent warming cannot be explained solely by natural factors.

Anthropogenic Factors:

 The course emphasizes that human activities, especially greenhouse gas emissions from fossil fuel burning, deforestation, and land use changes, are the primary drivers of recent climate change. Carbon dioxide levels have reached unprecedented levels, with current concentrations around 400 parts per million compared to 280 parts per million two centuries ago.

Economic Sectors and Greenhouse Gas Emissions: 

It is highlighted that the industrial and power sectors are the most significant contributors to greenhouse gas emissions, taking into account both direct and indirect emissions.

The lectures delve into the intricate and specialized knowledge systems of indigenous peoples and local communities, underscoring the depth of understanding these groups have concerning their environments, fostered through prolonged interaction with nature. It categorizes their knowledge into theoretical (e.g., recognizing animal species), practical (e.g., using a bow and arrow), and belief systems (world interpretations). Examples highlight the complexity of this knowledge: Australian Indigenous communities' celestial knowledge informs social organization and ceremonies, evident in artifacts like the message stick and stone arrangements aligned with astronomical events. Similarly, the Andean people's agricultural practices, honed over millennia, showcase an intimate adaptation to their environment, recognized globally for its significance. Further, the collaborative fishing practices between Brazilian fishermen and dolphins illustrate a sophisticated, mutualistic relationship between humans and wildlife, enhancing both parties' success. In Africa, the synergy between honey gatherers and the African honey bird showcases complex interspecies communication, leading to mutual benefits. These instances exemplify how indigenous and local community knowledge systems, deeply rooted in practical, theoretical, and belief-based understandings, contribute significantly to sustainable environmental interaction and conservation. 

The course discusses the contrasts and commonalities between scientific knowledge and local ecological (traditional or indigenous) knowledge systems, highlighting their distinct characteristics and the value of integrating these diverse knowledge systems. Scientific knowledge, developed over the past 150 years, follows a reductionist approach, focusing on breaking down reality into smaller, analyzable parts and relies heavily on controlled experimentation and written documentation. It aims at uncovering universal truths and understanding the mechanisms behind observed patterns in the natural world. In contrast, local ecological knowledge is holistic, incorporating physical and metaphysical elements, and is deeply rooted in long-term interactions with the environment. It is transmitted orally, often through storytelling, and is empirical, place-based, and context-specific, emphasizing practical applications. Despite these differences, both systems recognize the interconnectedness of the universe, are dynamic, and share values like honesty and inquisitiveness. They aim to understand environmental processes and phenomena, suggesting that integrating these knowledge systems through approaches like the multiple evidence-based approach can enrich our understanding of complex issues like climate change. This integration acknowledges the complementary and sometimes contradictory insights provided by each system, offering a more holistic perspective on environmental understanding and problem-solving.

This course highlights the intricate relationship between climate change and its multifaceted impacts on ecosystems and human well-being. It underscores the significance of robust data with temporal depth and broad spatial coverage for understanding climate patterns on a global scale. However, the availability of such data is limited, particularly in meteorological sciences, where there is an uneven global distribution of meteorological stations, affecting our comprehension of climate phenomena. The narrative emphasizes the limitations of global climatic models in capturing the localized effects of climate change and points out the existing knowledge gap in understanding the impacts on biological systems and human livelihoods. It brings to light the invaluable contribution of local and ecological knowledge, particularly from indigenous peoples and local communities, in identifying and interpreting climate change effects. This knowledge, rooted in long-term interaction with their environment, offers nuanced insights into climate change impacts and adaptation strategies. The text illustrates a growing scientific interest in integrating local ecological knowledge into climate change studies, as evidenced by the increase in related publications over the last 15 years. It also acknowledges the formal recognition of this knowledge by international bodies like the IPCC and the UNFCCC, highlighting its importance in enhancing our understanding of climate change and informing adaptation strategies. This narrative posits that leveraging local ecological knowledge can provide a more comprehensive understanding of climate change, bridging the gap between global models and localized impacts.

Collections in today’s digital language archives (i.e., digital repositories that specialize in language data) are multimedia, mainly born-digital, and frequently include very large files and/or large numbers of small files. The collections are made specifically for language documentation and preservation purposes; archiving happens soon after the materials are collected; and materials are accessible for many audiences via the internet.
