The diagram to the left shows how much CO2 and Methane gas can be produced by a herd of cow and sheep. It also indicates a proposed tax that some individuals feel the farmers should pay because their animals are hurting the environment.

The picture on the left shows a cow with a gas collecting backpack that was used to measure the amount of green house gasses that cows produce in their stomachs. || I predict in the next 20 years, there will be more and more cows and sheep on the Earth. If scientists do not not figure out a food that cows can eat that doesn't give them so much gas. the cows and sheep on the earth will cause global warming and billions of people will negatively affected. || || - The Mauna Loa observatory, Hawaii have had a rapid increase in CO2 concentration since industrialization. Carbon dioxide is the most important cause for global greenhouse warming. Humans also cause a big impact when ti comes to carbon dioxide.

- Methane is a chemical compound. The amounts of methane is smaller than Co2 but is greater in concentration. Methane is produced by anaerobic bacteria and is mostly found in wet areas for example, swamps, bogs, and wetlands. It could also be found in the guts of termites and animals such as cattle and sheep. The amount of methane has doubled since the 1800's. || - At the rate the Mauna Loa has there rapid increase, I believe in the next couple years it will keep on doubling until they change the way they are doing things.

- I believe that it will increase the same way it did from the 1800's to present day. || || The first picture is showing the carbon emissions from various sources. Although small in amount naturally, the increasing carbon dioxide in the atmosphere also increases the temperature on the land.

The second picture is showing the amount of CFC released from different sources. CFC isn't produced naturally that all sources are man-made. CFC is 20x better at trapping heat that Carbon Dioxide so excessive amount will definitely be harmful in our environment. || In the next 20 years, I predict that if we continue to burn the same amount of fossil fuels as we do now, we will totally destroy our Ozone Layer and might result to danger for both humans and the nature itself. || [|23/climatechange.carbonemissions?picture=333204031] []

|| ** __580-584 notes:__ ** -there are 4 natural causes for climate change. -Humans cause climate changes because of carbon dioxide and greenhouse gases. -Greenhouse gases, carbon dioxide, and methane gases are what make earth warm. -Carbon dioxide absorbs heat and cause earth’s lands to warm up faster. - Coal, natural gas, and petroleum are burning fossil fuels that add carbon dioxide to earth’s atmosphere. -Methane, nitrous gases, and chlorofluorocarbons are naturally produced and they absorb radiation that’s supposed to be release into space. Methane absorbs more radiation then carbon dioxide does. Methane is produced by anaerobic bacteria, where there’s not a lot of air or oxygen, such as swamps, wetlands, and animal intestines (cows and sheep). - nitrous oxide enters earth’s atmosphere because of agricultural activity. -Once gases enter earth’s atmosphere they don’t leave for a long time. -Earth’s lower atmosphere is warming, mainly because of carbon dioxide. -Trace gases are stable in the polar troposphere and its temperature is increasing. -A decrease in sea-ice causes temperatures to increase. -Evaporation is increased with warmer temperatures and water vapor. -Sea-ice has a highly reflective surface. -Clouds are produced from too much moisture in the atmosphere and cause earth’s temperature to rise. Clouds also absorb and reflect radiation. -Climate’s distributed unevenly because of trace gases and carbon dioxide. *Fossil fuels (coal) are burned, releasing carbon and carbon dioxide into earth’s atmosphere. Carbon dioxide absorbs heat, causing temperatures to increase globally. These gases take a long time to be removed from earth’s atmosphere once added.

 * Cows and sheep both release methane gas, which gets released into the atmosphere and absorb radiation. Methane is produced from anaerobic bacteria, which grows in wetlands, swamps, and animal’s intestines/guts. Methane is one of the main contributors of global warming and greenhouse gases. ||  ||

1st picture: This is a graph of global climate change from 1880 to the year 2000. The graph clearly shows that the temperatures keep rising (getting warmer). The highest it was in 2000, was about 0.56 degrees Celsius.

|| 4 potential, natural causes of climate change: *CO2 is also impacting climate change * human generated aerosols to the atmosphere *vegetation lessened by animals overgrazing the land and by the use of fire (humans) * human alternated ground cover and changed surface reflectivity, surfaces winds, and evaporation rates ~energy that leaves the ground is absorbed by CO2. The energy gets re-emitted and part of it goes back to the surface. This keeps the air near the ground warmer than it would be without CO2. ~CO2 levels are rising from burning fossil fuels such as coal, natural gas, & petroleum that are getting into our atmosphere. De-forestation also adds CO2 to the air because of decaying material. 40-50% excess CO2 is in the atmosphere ~Scientists think humans basically played a main role in climate change. ~In the future, land masses are expected to warm more rapidly than the global average, mostly at northern latitudes that are high. ~Humans also caused some trace gases…they’re called “trace gases” because they have less concentrations than CO2. Trace gases: Methane, Nitrous Oxide, and Chlorofluorocarbons. All the trace gases add to the greenhouse effect. ~In Polar Regions (high latitudes) trace gases will be2-3 times higher than on global average. Sea ice contributes to greater temperature increase. ~Warmer surface temperatures cause more evaporation. The ice reflects the sun but when ice melts, the dark bodies of H2O will absorb the sun. ~positive feedback mechanisms reinforces the initial change, negative feedback mechanisms are opposite of the positive feedback. Climate change feedback mechanisms is when a components of the climate system is altered & scientists consider lots of possible outcomes. || Within in the next 100 years, i predict that CO2 levels will get really bad and i think trace fossils will increse.

I also think that too much human impaction wll somehow mess up the carbon dioxide cycle.

I think global warming will continue to get worse and moe sea ice will be melting. || || One of the problems we face is the large amounts of CO2 in the atmosphere. Co2 emissions are increasing every year. Some of the amounts of CO2 are emitted by cars, planes, and the burning of fossil fuels. The first picture that is posted shoes that carbon dioxide is one the contributors to the greenhouse effect. The greenhouse effect is when heat it trapped in our o-zone layer because most polluants cannot escape, instead they settle n our atmosphere and absorb as much radiation from the sun. || I believe the temperature of the earth will increase every year, and it would come to a point where sea ice and glaciers will melt and eventually increase the sea level. Since most polluants cannot escape the ozone layer, it will continually absorb radiation and constantly warming the atmosphere. ||

||  ||   || || Layer of CO2 covers the Earth which is more resistant to letting out longer sun radiation. Carbon dioxide is an important heat absorber so without a doubt a change in the level of CO2 in the atmosphere would alter temperatures.

Humans have impacted the global climate in many ways. Industrial change made waste that was discarded into rivers/lakes/oceans. Different chemicals and gases are released into the air. CO2 isnt the only gas that has been effecting the atmosphere. Gases like methane, nitrous oxide, and chlorofluorocarbons are also at blame. All gases put together GREATLY impact the climate and future of Earth. || My prediction is that in the next 20 years the Earths global temperature will continue to increase or near what it is now. The levels of ice in the Arctic would continue to decrease and the sea level would rise higher. More intense and frequent storms would arise. || || As you can see from the chart there is an increase as each decade goes by. There isn’t a decline it’s mostly inclining. Carbon Dioxide is responsible for the greenhouse effect of the atmosphere. I read that for the last two centuries it has been fueled, and unfortunately it still continues. It is fueled by: coal, natural gas, and petroleum.

This picture shows pollution and how the gasses from factories, cars, and the environment are affecting the earth. All of these gasses being let out are building up increasing the global warming. I read that it’s likely that all the land areas will warm more rapidly than the global average at the northern high latitude in the cold season. || My prediction for the next 20 years is that it is not looking so good, I think it’s either going to increasing slowly or get really worse. Each day pollution is advancing and people do not even care. Greenhouse gases won’t stop it’s going to continue to spread. Different parts of the world are to advanced while others are worsening. ||

|| This image shows the CO2 levels rising in the atmosphere. Combustion of burning fossil fuels such as, coal; natural gas; and petroleum increases CO2 levels in the atmosphere and causes the temperature to rise. Humans and deforestation are the major factors for the release of CO2 in the environment. Humans use coal and other fuels as their most important usage. Also, as vegetation is burned or decays, carbon dioxide is released.

The second image shows that the global temperatures actually increase due to the effect of increase in carbon dioxide in the atmosphere. The global surface average temperature increased by about 1°F. Most of the warming was observed in past 50 years by human activities, which were the major leading cause to this type of change.

|| As the graph shows that CO2 level in the atmosphere has kept increasing in past few decades, it can be predicted that the CO2 level will keep increasing for future decades, too.

As the details of Graph 2 shown, it can be predictable that after a century-100 years- the global surface temperature will rise from 1.4 to 5.8°C. Also, during the cold seasons, it is likely to predict that there will be rapid warming in all land areas than the global average. || \ || My first image is an image of carbon dioxide. Some of the energy leaving the ground is absorbed by atmospheric carbon dioxide. This energy is later reemitted, part of it towards the surface, so it keeps the ground warmer than it would without CO2. Carbon dioxide is highly responsible for the greenhouse effect of the atmosphere. Since carbon dioxide is a heat absorber, changing the carbon dioxide level could change our tempreatures.

The second image i a graph that shows co2 concentrations, and the global average temperatures through 1880 and 2010. As stated i the book, because there was an increase in the atmosphere's carbon dioxide, there was a temperature increase. Human activity has played a specific role. The climate is only getting hotter amd the future isnt looking good || I predict that if people dotn stop buning all these fossil fuels like coal,natural gas and petroleum the future is looking even worse and only getting increased climates. The projected rate of warming is much larger than the observed changes. Nearly all land will warm faster than the global temperatures. ||

|| -The carbon dioxide problem has been give much less attention than alternative fuel or biomass-derived energy production yet it is very important as chemical production creates billions of tons of carbon dioxide each year. But fear not as an analysis has concluded that use of existing biotechnology in the production of so-called bulk chemicals could reduce consumption of non-renewable energy and carbon emissions by 100 percent.

- The diagram illustrates several aspects of global warming. The rapid increase, and earlier increase is statistically highly significant. One can also see that the 1990s most probably have been the last millenium's warmest decade. || my prediction for the next 20 years it that we will definitely see all the things we were trying to avoid this year. We do not communicate and as result we will see things such as animals dying and the earth not being as well as it could ahve been if we to contritube. ||
