It has caused excessive heating up of earth and now a days is a tropic of concern. Global Warming Facts : Global Warming Facts • The 1990s were the warmest decade since 1861, when thermometer records began. • 1998 was the warmest year on record. • The temperature increase of the 20th Century was the largest of any century in the last 1,000 years. • The ten hottest years since the beginning of the last millennium have all occurred since 1983.

Slide 12: Sectoral Impacts: Direct Agriculture Increased vulnerability over Tropics & Sub-tropics Crop Diseases Health Thermal Stress Increase in vector & water borne diseases Eco-systems Species become endangered Migration of biomes Slide 13: Sectoral Impacts: Direct Power Increased Power demand Water Resources Glacier retreat Stress on Water Supply Coastal Zone Salanization, Soil Erosion, Displacement of population Weather Monsoon Variability, Extreme Weather Events Slide 14: Sectoral Impacts: Indirect Almost all Sectors of Human Activities Cumulative Effect on Industrial Infrastructure and Economic Growth With Consequences on Societal Balance Impact of Monsoon variability on Agricultural demand and consequences on Industry Slide 15: Greenhouse Gas Emissions by Sector Slide 16: Global Average Annual Temperature Anomaly (oF)From meteorological stations 1880-2005 Hansen et al. (2001) J. Geophysical Res. Vol 106, p. 23,947-23,963 Data from http://www.giss.nasa.gov/data/update/gistemp/ Slide 17: Sea Surface Temperatures Gulf of Maine 1.1oF warming over last 150 years 1.6oF warming over last 150 years Slide 18: Sea Level Rise Slide 19: CLIMATIC CHANGES Climate Change in spite of Uncertainties, is a Reality Slide 20: Climate Change is a Direct Consequence of Unsustainable Consumption driven by wasteful, consumerist, energy intensive production & consumption systems Slide 22: (1000 years) temperature records Projected Temperature Change, 1910 -2040 : Projected Temperature Change, 1910 -2040 Slide 24: Climate change and extreme climate events Weather regimes in ARPEGE-Climat Stretched grid, Variable Resolution ~ 60 Km over France and Spain ~ 600 Km over the Southern Pacific Data: -3 simulations of control (1960-1999) -3 simulations of scenario A2 from IPCC (2070-2099) Slide 25: Climate change and extreme climate events Weather regimes in ERA40 (winter) Slide 26: Climate change and extreme climate events Weather regimes in ERA40 (summer) Slide 27: Climate change and extreme climate events - Extreme events are identified by a threshold value (5%, 95% quantiles). - Variables: Tmax, Tmin, Precipitation, Storm Tracks Extreme climate events Change of probability: C = (Px/5)-1) *100 Px=10; C=100% Px=15; C=200% Px=0; C=-100% !! Slide 28: To Conclude…. There is an urgent need to evolve an Umbrella mechanism to integrate relevant Scientific Knowledge Base to deal with Climate Change Issues. Through S & T capacity building, nurture new technologies to generate user friendly products required by Stakeholders for initiating proactive actions and evolve new policies in National and International Context. Considering India’s strength, a bright opportunity exists for us to take a lead role in the Tropical Asian region by giving the Centre an International dimension.
