First of all, in order to describe in the figure I found the definition that might guide me to describe it well. So, “Carbon dioxide (CO2). A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. Humans have increased atmospheric CO2 concentration by a third since the Industrial Revolution began. This is the most important long-lived "forcing" of climate change”. The figure showed us the changed that happened since 1870 till 2000. Taking these different influences into account, it is possible to determine how much the temperature decreased when carbon dioxide was reduced, and use this figure to determine how much temperature might increase as carbon dioxide increases. After I read some articles, I found that when the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.
It can be clearly seen from the figure provided is that the concentration was very low in the year of 1950 but it was constantly increasing to reach the peak in the year of 1970. After 1970, the number is significantly dropped exactly in 1990. According to the notes, I realized there was a clean air act update in the year of 1990.
This figure shows concentration of methane in the atmosphere from 1000 years to 2000, in 1000 the methane around 650 to 750 and it goes in the middle for example in 1500 it increased up to 750 and it continue between the 650 and the 750 in the 1800 it increases up to 1750
Figure 1.5 presents the changes in Nitrous Oxide. It shows that from year 1750 to 1950 the Nitrous Oxide was stable and has no change between 250 and 300. However, in year 1950 the number had a little increase to year 2000 to be almost 310.
In the past 1000 years it was in the middle it goes up and down but when it reached 1900 it increases about 0.8 in the graph. However, in the 1250 it increased up to 0.1. In 1900 it starts to increase up to 0.6 in 2000.
Each of these greenhouse gases affects climate differently. Some gases can trap the sun’s energy better than others. The degree to which a gas traps solar energy is called its radiative forcing value. Radiative forcing values are indicated on the right axis of the graphs. The higher the radiative forcing value, the stronger its effect on global warming.
By 2100, the range of temperature increase is expected to be between 1.4 and 5.6.
North hemisphere appears to have experienced the most significant temperature changes. Because the northern hemisphere is warming faster than the southern hemisphere, with some of the most rapid warming rates on earth located in the Arctic. Northern hemisphere is winning now and projections show that, largely due to the influence of manmade greenhouse gas emissions. Also, the northern hemisphere has led the southern hemisphere in its rate of warming since about 1980, largely because the northern hemisphere has more land and less ocean than the southern hemisphere, and oceans warm relatively slowly.
AS it’s mentioned in the link “Climate changes affect ecological systems, and changes in ecological systems influence the processes of disease transmission. Changes in temperature and precipitation, as well as extreme climate events such as floods or droughts, are capable of changing ecological systems. For example, research links increases in diarrheal disease to flooding, and cholera outbreaks to warmer sea surface temperatures. Different weather conditions are known to affect vector-borne diseases such as malaria and dengue”. The key fact that I got from this articles the climate change affects the social and environmental determinants of health – clean air, safe drinking water such what happened in flint Michigan as you mentioned in last lecture.

Q1A:
In the diagram figure 1.1 shows that from 1860 to 1940, the temperature is increasing and
decreasing below and on the 0 C. From 1940 to 1980 the temperature was increasing and
decreasing on the 0 C. From 1980 to 2000 the temperature is increasing
above the 0 C and went
up to 0.6 C. From 2000 to 2100 the temperature starts increasing from 0.6 C to 1 C, and from
there the temperature is increasing until 2100 the temperature is 5 C.
