1. Raise your voice , not the sea level World Environment Day Celebrations -2014NLC, Neyveli - June 5, 2014 Dr. K. Kumaraswamy Chairman, School of Geosciences Bharathidasan University Tiruchirappalli – 620 024 E-mail :kkumargeo@gmail.com

2. Dynamic EarthLand – Water Boundaries • Plates of the Earth – 14 + 14 • Dynamic – Space and Time • Natural and Anthropogenic Activities • Natural movement and sea level rise • Anthropogenic Activities and Sea level Raise • Small Island Developing States (SIDS) 52 • Action : Global to Local / Local to Global

9. Relative size of Earth ! ? Big, Bigger, Biggest Small, Smaller,Smallest

15. The Universe…..!? Where are we…..?

16. WHAT IS THE LESSON ?

17. Physical evidences of global climate change : Record-breaking global average temperatures for air, land surfaces, lakes, and oceans; Ice losses from mountain glaciers and from the Greenland and Antarctic ice sheets; Declining soil-moisture conditions and resultant effects on crop yields; Changing distributions of plants and animals; Global impact of global sea-level rise, which threatens coastal populations and development.

18. CAUSE AND EFFECTS OF GLOBAL WARMING Rise in Atmospheric CO2 Methane.. Increased Greenhouse Effect Global warming Melting of Ice Sheets Altered Biomes Temporal Changes Increased rainfall and evaporation Rise in sea level Flooding Loss of coastal habitat Breeding pests Extinction of Some species Disease Antibiotics ?

19. Carbon dioxide emission China took the lead in overall carbon dioxide emissions (29%), with the United States second (16%), and the European Union third (11%). On a per capita basis in 2011, China, with 19.5% of global population, produced 7.2 tonnes per person, on par with the European Union (at 7.5 tonnes per person). The United States, with 4.5% of world population, produced 17.3 tons of CO2 emissions per person. Among the world’s major industrialized countries, Australia had the highest per capita CO2 output at 18.3 tonnes per person in 2011. 2

21. Climate Change Science : It is an interdisciplinary study of the causes and consequences of changing climate for all Earth systems and the sustainability of human societies. Climate change is one of the most critical issues facing humankind in the twenty-first century

23. There is still a considerable lack of awareness about the interrelated nature of all human activities and the environment. • It is due to inaccurate and insufficient availability of information, especially in developing countries. • Sensor based in situ data collection, remotely sensed data products, Geographical Information System based analysis etc., would enhance the precision and quality of environmental analysis. • Besides, there is an urgent need to increase the public sensitivity to environment issues and involvement of various disciplines in solving environmental problems.
