The Future Positive Feedbacks to Global Warming Warming oceans and soils are absorbing less CO 2 , so more CO 2 is accumulating in the atmosphere. Melting permafrost is now emitting CO 2 and methane; the more melting, the greater the emission.

The Future

Slide 2

Positive Feedbacks to Global Warming seas and soils are engrossing less CO 2 , so more CO 2 is amassing in the environment. Liquefying permafrost is presently discharging CO 2 and methane; the all the more softening, the more prominent the emanation. The warming methane hydrates on the Siberian mainland rack are starting to emanate methane and CO 2 . The diminishing ice and snow spread is uncovering more dim surfaces creating more surface and climatic warming. A warming air holds more water vapor (an in number nursery gas) expanding the temperature.

Positive Feedbacks Can Lead to a Non-straight Climate Response

The 800 lb Gorilla Nobody Wants to Talk About: ABRUBT CLIMATE CHANGE Some huge characteristic atmosphere changes have happened suddenly. In a few examples, the normal worldwide temperature has risen or fallen >8⺠C in under 10 years, and no less than one in as meager as 5 years. An increment of 6ⰠC in this century would be viewed as an unexpected environmental change. The trigger for the unexpected temperature rises is not surely knew but rather presumably includes a calamitous arrival of methane and carbon dioxide. An Earth-wide temperature boost could trigger a sudden environmental change. On the off chance that this happened its belongings would unquestionably be calamitous . The late quickened dissolving of permafrost and expanded barometrical methane could be the start of a sudden environmental change.

Scenarios of Future CO 2 Global Emissions and Concentrations

Probability Distribution for Committed Warming of 2.4°C starting 2005

Slide 15

Possible Political and Societal Consequences Three Climate Change Scenarios : Expected (1.3â° C Increase) Severe (2.6â° C Increase) Catastrophic (5.6â° C Increase) Reference: The Age of Consequences: The Foreign Policy and National Security Implications of Global Climate Change, Center for Strategic and International Studies, Washington, DC , November 2007.

Slide 16

Scenario 1 (Expected) Global Temperature Anomaly = 1.3â° C Sea level ascent of around 0.23 meter This temperature irregularity is verging on certain due to the framework's dormancy. The ideal opportunity for this condition is most likely about the year 2040.

Slide 17

Environmental Stresses Water Scarcity for ~1.7 billion individuals Tropical Infectious Diseases Spread North Frequent Flooding for more than 3 million individuals About 30 million individuals subject to starvation

Slide 18

Political and Societal Stresses Conflicts over assets About 25 million individuals uprooted from waterfront territories Immigrations from nations with across the board ailment causes political turmoil Dissatisfaction with governments may radicalize interior legislative issues Social administrations get to be weight to governments Large diminishing in world GDP

Slide 19

Scenario 2 (Severe) Global Temperature Anomaly = 2.6â° C Sea level ascent of around 0.5 meter This situation looks more likely. The ideal opportunity for this condition may be about the year 2040.

Slide 20

Environmental Stresses Sea level ascent of ~0.5 meter Water lack influences more than 2 billion individuals About 50 million individuals dislodged from beach front ranges Up to 15 million individuals face serious flooding Significant increment in sicknesses including ailing health and irresistible ailments Major changes in marine biological communities because of sea fermentation

Slide 21

Political and Societal Stresses Wealthier countries incite poorer profoundly focused on countries to forsake popular government and increment forceful conduct to neighbors Global fish stocks accident creating clashes among countries for sustenance. Numerous countries may privatize water assets bringing about inward changes Globalization will most likely end and quick monetary decay will happen. Organization together frameworks and multinational establishments may end. Private organizations may turn out to be more essential than governments

Slide 22

Scenario 3 (Catastrophic) Global Temperature Anomaly = 5.6â° C Sea level ascent = 2 meters This condition may happen about the century's end

Slide 23

Environmental Stresses About 170 million individuals uprooted as a result of ocean level ascent Water shortage influences around 3.2 billion individuals (half today’s populace) Collapse of the marine biological system Mass starvation because of yield disappointments and fish consumption Large increment in passings because of high temperatures, spread of ailments and lack of healthy sustenance Mass termination of more than half of existing species

Slide 24

Political and Societal Stresses Massive movement toward the north (U.S., Canada, Russia and Europe) prompts confusion in these areas Rage at governments, ascend in religious radicalism, and antagonistic vibe and viciousness toward workers prompts political disarray Economic breakdown is an unmistakable probability Nuclear war is likewise a plausibility Probably the end of development as we probably am aware it .:ts
