Cities are dynamic systems resulting from the complex interaction of various socio-ecological and environmental developments. Climate change disproportionately affects cities mostly located in climate-sensitive areas; thus, these urban systems are the most critical in modern societies under changing climate scenarios, uncertain disruptions, and urban inhabitants' daily lives. It is essential to analyze the challenges in the metropolitan area through the lens of climate change. The present work analyses the challenges in Chennai, a coastal city in India and one of the chief industrial growth canters in Indian and South Asian region. The challenges are analyzed through the city’s system analysis via land use, green cover, population, and coastal hazards. Land use and green cover changes are studied through satellite images using ArcGIS and assessing coastal risks due to sea-level rise through GIS-based inundation model. There are drastic changes in land-use patterns; the green cover had reduced much, including agricultural and forest cover due to rapid urbanization. The land use has changed to 59.6% of the reduction in agriculture land, nearly 40% reduction in forest land, and 47% of the wetland over time. The observed mean sea level trend for Chennai is + 0.55 mm/year from 1916 to 2015 and the area of 21.75 sq. km is under the threat of inundation to 0.5m sea-level rise. The population growth, drastic changes in land use pattern, green cover reduction, and inundation due to sea-level rise increase the city's risks to climate change. There is a need to ensure that future land-use developments do not worsen the current climate risk level, either through influencing the hazards themselves or affecting the urban system's future vulnerability and adaptive capacity. The study also urges the zone level adaptation strategies to ensure the resilience of the city.

<p>The essential role of education in addressing the causes and consequences of anthropogenic climate change is increasingly being recognised at an international level.</p><p>The Office for Climate Education (OCE) develops Climate Change Education (CCE) resources that support teachers and education systems in developed and developing countries to mainstream climate change education in their respective contexts. The OCE organises capacity building/professional development workshops worldwide for educators. It has also initiated and coordinates a large network of stakeholders to scale up their actions towards climate change resilience.</p><p>Drawing upon the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate, the OCE has produced a set of educational resources and tools for students to understand climate change in the context of the ocean and the cryosphere. These cover the scientific and societal dimensions, at local and global levels, while developing students’ reasoning abilities and guiding them to take action (mitigation and/or adaptation) in their schools or communities. These resources include:</p><ol><li>Ready-to-use <strong>teacher handbook</strong> that (i) target students from the last years of primary school to the end of lower-secondary school (aged 9 to 15), (ii) include scientific and pedagogical overviews, lesson plans, activities and worksheets, (iii) are interdisciplinary, covering topics in the natural sciences, social sciences, arts and physical education, (iv) promote active pedagogies: inquiry-based science education, role-play, debate, project-based learning.</li> <li><strong>Summaries for teachers</strong> of two IPCC Special Reports (“Ocean and Cryosphere in a changing climate” and “Global Warming of 1.5°C”). They are presented together with a selection of related activities and exercises that can be implemented in the classroom.</li> <li>A set of <strong>10 videos</strong> where experts speak about a specific issue related to the ocean or the cryosphere, in the context of climate change. These videos can be used either to initiate or to conclude a discussion with students on their specific topic: urban heat islands, glaciers, ocean acidification, tropical cyclones, marine energy, sea ice melt, thermohaline circulation, El Niño, mangroves, sea level rise.</li> <li>A set of <strong>4 multimedia activities</strong> offering students the possibility of working interactively in different topics related to climate change: sea level rise, food webs, carbon footprints and mitigation/adaptation solutions.</li> <li>A set of <strong>3 resources for teacher trainers</strong>, offering turnkey training protocols on the topics “greenhouse effect” and “ocean”, as well as a methodology for producing locally-relevant education projects.</li> </ol>

Researchers identify the main sources of uncertainty in projections of global glacier mass change, which is expected to add about 8–16 centimeters to sea level, through this century.
