NOW OUR PLANT IS BETRAYING US……..

GLOBAL WARMINGAND ITS EFFECTS : 

GLOBAL WARMINGAND ITS EFFECTS BY DR. MARYAM FAROOQ PGR, MAYO HOSTPITAL LAHORE

Slide 11: 

Earth Health? OR Earth Hype? Although people don’t all agree and take interest, it's possible that we are too late to reverse the course we are on. A course that may have catastrophic consequences. If we wait to convert those who disagree we will definitely doom future generations to a calamity not of their making.

Earth’s Temperature : 

Earth’s Temperature

Greenhouse Effect : 

Greenhouse Effect Sun

Earth’s Atmospheric Gases : 

Earth’s Atmospheric Gases 99% 1% Non Green House Gases Greenhouse Gases

Worldwide Carbon Emissions : 

Worldwide Carbon Emissions Carbon (109 metric tons) 0 1 2 3 4 5 6 7 8 1750 1800 1850 1900 1950 2000 Year

Recorded Worldwide Temperatures :

Slide 24: 

Two studies showed the total number of hurricanes has not changed However, the intensity of hurricanes has increased (more category 4 and 5 hurricanes and cyclones) Probably due to higher sea surface temperatures (more energy)

Effect on Humans : 

Effect on Humans Fewer deaths from cold, more from heat Sea current changes leading to affect on sea food resources Droughts , Hurricanes Migration s due to food shortages Disease pattern changes

Potential Worldwide Precipitation Changes : 

Potential Worldwide Precipitation Changes

Drought . Deforestation. Climate Instability : 

Drought . Deforestation. Climate Instability Severe Rainfall Deficiency in Australia Australia produces over 1.4 million tonnes of rice a year and exports rice to over 70 countries but over the last few months rice production has declined to an all time high. Australia is a Major exporter of wheat to the global market but drought has caused lower production leading to higher prices. Drought In Thailand Over 60,000 acres of farmland have been hit by drought In Thailand the world’s largest exporter of rice causing export restriction leading to rice shortage and high prices In the global Market.

Declining Rainfall in Africa : 

Declining Rainfall in Africa Drought in Sierra Leone, Senegal, Ethiopia, Djibouti, Ghana, Kenya, Chad and other African Countries has marked decline in crop production such as Soya beans, cassava, Maize and Sorghum.. Anarchy Looms

Wildlife Effects : 

Wildlife Effects Polar Bears Require pack ice to live Might eventually go extinct in the wild Sea turtles Butterflies Other species may go extinct as rainfall patterns change throughout the world Change in season for Mosquito breeding and spread of infections..

Solutions… : 

Solutions… Conservation Reduce energy needs Recycling Alternate energy sources Nuclear Wind Geothermal Hydroelectric Solar Fusion?

Storage of CO2 in Geological Formations : 

Storage of CO2 in Geological Formations Depleted oil and gas reservoirs CO2 in enhanced oil and gas recovery Deep saline formations – (a) offshore (b) onshore CO2 in enhanced coal bed methane recovery Adapted from IPCC SRCCS Figure TS-7 3a 2 3b 1 4

Other Solutions… : 

Other Solutions… Reuse Recycle Reduce single vehicle usage Walk…. Cope….. Plant trees… save your lungs and give nature its.. Save…. Don’t Waste….

Thank you for listening and For Doing things to save earth….
