Climate Change Contribution

1. The Philippine's main sources of Carbon Dioxide emissions were from liquids, solids, and cement. These sources are not surprising at all. They were normal.
Also, the year the Philippines started emitting significant amount of carbon dioxide is 1982. There were the Asian adult games - which is similar to the Olympics. Therefore, that is probably the event that started to have a lot of travelers and tourism activities going on that year. On top of that, activities and carbon dioxide emissions will probably start from there which explains the carbon dioxide emissions spiking up.

2.  The highest of per capita CO2 emissions estimates for Philippines is 0.275. Compared to U.S's 4.9 metric tons of carbon, that is 0.06% of that. That is very little compared to the US. This is because the Philippines' population is much lower than US. Also, there is less urban areas in the Philippines than in the US.
The Philippines' ranking on per capita CO2 emissions is 156. Meanwhile, the rank of United States is 12.
As the blog author, I feel Philippines is doing very well in not releasing so much carbon dioxide emissions as a whole.

3. The Philippines is significantly and surprisingly low compared to some other countries on the graph. Historically, US and China and other countries have seen increasingly industrial development and human activities. Therefore, their carbon dioxide emissions are super high up there compared to Philippines.
In 2008, China was the biggest emitter of carbon dioxide according to the data and the graph above.
If the US has 312,000,000 people and China has 1,338,000,000 people, on per capita basis, an American citizen is more at fault for emitting carbon dioxide. Because on average, (if you do the math), an American contributes way more then a Chinese citizen. Philippines' cumulative contribution is 611,173 thousands metric tons of carbon emissions. USA's cumulative contribution is 94,225,770 thousands metric tons of carbon emissions. China's cumulative contribution is 36,152,061 thousands metric tons of carbon emissions. India's cumulative contribution is 10,229,326 thousands metric tons of carbon emissions. Therefore, USA is responsible for the most carbon dioxide emissions cumulatively. China cumulatively emits 38% of the US emissions. Also, India cumulatively emits 11% of the US emissions.

The graph above shows the global emissions of carbon. Comparing this to the Keeling curve in #1, they are both definitely increasing; however, emission and concentration are two different concepts. As the globe emits more and more metric tons of carbon year by year, the curve of the concentration graph gradually increases as well. The concentration won't decrease because the Earth's carbon cycle does not make the carbon dioxide go away in our atmosphere as quickly as it emits carbon dioxide into the atmosphere. Therefore, it will continue to increase. But the slope is the most important part because it represents the increase in emissions per year as well.
