4. Is this Greenhouse process beneficial to our Earth Yes….but this warming process must be regulated to ensure that it benefits our living environment. To much GHG in our atmosphere means are earths weather temperatures may increase due to an abundance of trapped UV rays. This thermal increase would manipulate air pressure and throw off weather patterns across the globe. So far, the total global temperature increase from the 1850’s through to 2005 is 0.76°C (1.36°F) and the rate of warming averaged over the last 50 years is nearly twice that for the last 100 years.
7. Today's Atmospheric conditions Our atmosphere today is comprised of a mixture of oxygen and nitrogen that makes up 99% of our atmosphere. The other 1% is greenhouse gas. Although greenhouse gas makes up such a small percent of our atmosphere, the gas does an excellent job of blocking and trapping solar rays to cause the greenhouse heating effect. Deforestation, largely driven by conversion to cropland, accounts for roughly 16% of global emissions of the carbon dioxide warming the atmosphere Human activity (primarily related to fossil fuel consumption) has already changed atmospheric characteristics such as temperature, rainfall, levels of carbon dioxide (CO2) and ground level ozone.
8. Consequences of Global Climate Change The climate change will be a global affair and both developed and undeveloped countries will deal with weather related hardships. These negative consequences include: glacial melting, permanent costal flooding an increased frequency and magnitude of tropical storms hurricanes, tornados longer drought seasons hotter summers and colder winters Regional wars and civil wars may take place as undeveloped countries fight over the control of relocated fertile growing lands resulting from the weather change. Additionally, the enduring changes in climate, water supply and soil moisture could make it less feasible to continue crop production in certain regions
9. Effects on developing countries While climate change will affect everyone, it is expected to have a disproportionate effect on those living in poverty in developing countries.Climate change impacts in developing countries: Environmental Impacts Changes in rainfall patterns Increased frequency and severity of: Floods Droughts Storms Heat waves Changes in growing seasons and regions Changes in water quality and quantity Sea level rise Glacial melt Areas that are and will be affected Water resources Agriculture and forestry Food security Human health Infrastructure (e.g. transport) Settlements: displacement of inhabitants and loss of livelihood Coastal management Industry and energy Disaster response and recovery plans
10. What can be done to help? To prevent this agricultural crisis, the IFPRI (International Food Policy Research Institute) estimates, would require an investment of at least $7 billion per year in the most affected countries in Asia, Africa and Latin America for increased agricultural research into, for example, drought resistant crop varieties.

13. There are uncertainties Significant uncertainties remain concerning the direction of climate change, especially in Africa and at a regional level, where there is a lack of observational data and where modeling studies are limited. Uncertainty lies in the exact magnitude, rate and geographical impact of climate change. This is often seen as a barrier to precautionary action or adaptation, but development and aid agencies stress that this should not prevent or slow down adaptation efforts.
14. Possible atmospheric conditions for the future (2075 to 2100) Right now and since the birth of our planet, our greenhouse gas levels have remained at a steady 1% which has allowed are planet to maintain its ambient livable temperatures. If our GHG emissions don't decrease significantly in the near future then our atmospheric GHG levels may increase to 1.003,1006, or even 1.009. GHG levels anywhere from 1.003 to 1.006 may increase our planets average temperature to 10 degrees higher than what's normal.
