Slide 3

Global Warming Global Warming is characterized by the NIEHS as: The dynamic steady ascent of the Earth’s surface temperature thought to be brought about by the nursery impact and in charge of changes in worldwide atmosphere designs.

Slide 4

Global Warming Global warming has happened in the inaccessible past as the consequence of common impacts, yet the term is frequently used to allude to the warming anticipated to happen as an aftereffect of expanded emanations of nursery gasses.

Slide 5

Greenhouse Gasses While there are various reasons for a worldwide temperature alteration, the two primary gasses included are CO 2 Water Vapor They make protection around the earth holding in the warmth. This extra warmth warms the earth creating ice tops to soften and other climate wonder.

Slide 6

Comparing Atmospheric CO 2 Levels and Temperature Change

Slide 7

Other Greenhouse Gasses Other nursery gasses: Anthropogenic discharges Methane (CH 4 ) Carbon Monoxide (CO) Chlorofluorocarbons (CFC) Hydro Chlorofluorocarbons (HCFC) Ozone (O 3 ) Nitrous Oxide (N 2 O)

Slide 8

Greenhouse Gasses While CO 2 outflows are the essential wellspring of the nursery warming impact, alternate gasses are measured by CO 2 identical impact

Slide 9

Causes of Gas Production Carbon Dioxide Fossil fuel ignition Deforestation Methane Flooded soil crops (e.g. rice) Fossil fuel mining Ruminants Landfills Organic squanders Human invigorated eutrophication

Slide 10

Causes for Gas Production Nitrogen Oxides Nitrogen manures Fossil fuel ignition Chlorofluorohydrocarbons Release of refrigerant CFCs

Slide 11

Impacts of Global Warming Elevated temperatures of the biosphere dissolving of polar ice increment in ocean level (flooding of significant urban communities) increment of methane from permafrost Weather extremes more precipitation amid shorter periods more vanishing and soil dampness lacks Ecosystem interruption anxiety and demise of vegetation movement of creatures Human Health warmth stress relocation of illness vectors

Slide 12

Socioeconomic Issues Developed nations utilize the vast majority of the fossil vitality. U.S. has 4% of the world populace and uses 25% of the vitality Developing nations use around 10% of vitality for every capita as the U.S. In the U.S., vitality utilization is 36% for building, 32% for transportation, and 32% for industry Power plants waste vitality ( a 400 MW plant squanders 800 MW of warmth vitality) Developed nations have created on the premise of utilization of vitality and deforestation. By what method would we be able to request that rising nations not do likewise?

Slide 13

Trends of Global Warming According to a models' number used to anticipate the patterns in a dangerous atmospheric devation there is relied upon to be an increment in temperature from 1.4  C to 5.8 C by the year 2100. This would be an increment pretty nearly proportional to the adjustment in temperature increment between the ice age and today.

Slide 14

Earth’s Climate History Increases of 2.1–5.7 o C are anticipated because of nursery gasses: A 1-1.5 o C worldwide normal warming would speak to an atmosphere not experienced subsequent to the start of agrarian progress (6,000 years back) A 1-2.5 o C warming speaks to an atmosphere not experienced following 125,000 years prior when little human groups existed. Such an atmosphere appeared to halfway break down the West Antarctic Shield, raising ocean levels 5-7 m A 3-4 o C warming has not been experienced since people showed up on Earth (2 million years prior). The last time Earth experienced such an atmosphere spoke the truth 3-5 million years back.

Slide 15

Estimated Effects of Global Warming A late UN study predicts that a temperature ascent of 1.4  C to 5.8 C through the span of the coming century could bring about the accompanying: Sea levels ascending by 0.5 – 1.5 m throughout the following couple of decades and a few meters in the long haul More continuous climate extremes delivering surges, torrential slides, keep running off water accessibility, soil disintegration Droughts, loss of soil dampness Reduced precipitation in mid-scope locales of N. America and Eurasia

Slide 16

Estimated Effects of Global Warming continued… More stagnant air masses for more time periods Severe effect on horticultural efficiency overall Die off of unmanaged timberlands Reduced stream streams Increased mortality because of warmth stretch and spread of irresistible illnesses

Slide 17

Estimated Effects of Global Warming Flooding Caused by a 75m Increase in Ocean Depth

Slide 18

Evidence for Global Warming Atmosphere CO 2 levels have expanded from 230 to 250 ppm (30% since pre-modern and amid mechanical age) Atmospheric methane levels are expanding around 1% every year Temperature of the earth surface has expanded by 0.4 o C Temperature of sea has expanded by 0.5 o C October 6, 1997 was the most sultry temperature on record for that time In 1995, >400 persons passed on of warmth stroke in Chicago

Slide 19

Evidence for Global Warming Number of days with temperatures underneath solidifying has dropped from 90 in 1990 to 15 in 1997. Tempest and dry spell conditions are more noteworthy than can be clarified by ordinary climate changes 5-10% expansion in precipitation in the 20 th century Floods in the U.S. what's more, China have been 10x more incessant in the previous 10 years ocean level has risen 0.5 cm in a decade ago, 25 cm in a century ago

Slide 20

Conference of Parties III 1997, at the Conference of Parties III (COP3), Kyoto, Japan, the Kyoto gathering on environmental change occurred. There, created nations consented to particular focuses for cutting their discharges of nursery gasses. A general structure was characterized for this, with specifics to be point by point throughout the following couple of years. This got to be known as the Kyoto Protocol.

Slide 21

KYOTO Protocol The goal of the Kyoto Protocol is to settle and diminish nursery gas outflows, moderate environmental change, and advance practical improvement. The Protocol is noteworthy in that it is the first endeavor to accomplish worldwide understandings to moderate worldwide environmental change through decrease in GHGs, and the first to utilize the adaptability of the worldwide commercial center for worldwide natural administration.

Slide 22

KYOTO Conference December 10, 1997 1500 representatives from 160 nations Goal: to touch base at legitimately tying bargain for an unnatural weather change moderation Most created nations would build emanations by 20% with a the same old thing arrangement

Slide 23

KYOTO Conference Pre-gathering Goals by Country by 2010 European Community, - 15% C discharge Japan, - 15% U.S., - 3% Australia, +18% Post-meeting Goals Developed Countries, - 5 Australia, +8
