Lab
This week in lab we discussed the following big questions: What type of data do we have that supports that climate change is happening? What questions did you derive from the data shared? What answers did you find? Using SPECIFIC data, make a climate statement based on DATA.
My group came up with: Based on the Annual State-Wide Average Number of Frost-Free Days, we can tell based on the inconsistency, that the frost is in inconsistent and overall has less frost days. Gradually throughout the years the days are increasing without frost. Snow fall has decreased overtime, and the growing season ahas gradually increased (along with allergies). Temperature, habitat, precipitation, weather are all changing throughout the time allotted. Iowa has seen this change with longer growing seasons, wetter springs and summers, more summer precipitation, higher humidity, and drier autumns. This will be a direct impact Iowa economy which is based on agriculture since it allows more crops to be grown with a longer growing season and an increase in frost free days. This will also cause an increase in the amount of flooding which destroys crops and have a drastic impact on the economy negatively. Why was there an increase in perception for two years, 1882 and 1901?
Lecture
In the lecture, we talked about how science is no longer debating if climate change is real. Science is now stating that climate change is real, and caused by humans the next move science is making is how can we fix climate change? One question we asked during the lecture was "Why do some areas have a hot climate, and other areas have a cold climate? There are 6 key factors, Latitude, Ocean, Wind & Air, Elevation, Relief, and lastly Near water. In the lecture we also talked about evidence of how climate change has happened, we can see it through some glaciers. Ice that is in water does not cause water to rise, but ice from the land melting is what causes water to rise. Glaciers melt even faster due to the positive feedback loop because dark ice absorbs the heat which causes melting, while white ice causes reflection of the heat.
Pressbook
The press book greenhouse gas model helped me learn how some radiation is reflected into space, and other radiation is absorbed by greenhouse gasses which is in turn reflected throughout the atmosphere warming the Earth. I thought the image of a positive feedback loop was the most helpful because in a lecture I was struggling to understand how the loop worked but the image helped me understand it. I would like to learn more about how ice cores help scientists learn about carbon dioxide levels over time.
