Science Methods 2 Blog Post 13

 Lab 

In lab today the big question in lab was "What is the science behind climate science?" we talked about how different gasses affect the Earth's atmosphere, we learned this through a video we watched in class as well as through a simulation we used. We also discussed our interviews with an elder about climate change and how elders see climate change in the world today, and compared that to data on how the Earth's surface temperature is rising. 

Press book 

In the Press book I learned more about what greenhouse gasses are, "Greenhouse gases are complex molecules made of three or more atoms bonded together. Gases move quickly and collide with other molecules in the atmosphere (2019, Neal)." I found that the press book helped my understanding of the negative effects of greenhouse gasses, according to the textbook the greenhouse effect is when the Earth's atmosphere traps heat which is what causes global warming. I would like more information about how we as a community can reduce the amount of greenhouse gasses we are letting expel into the atmosphere. 

Lecture 

We talked about how in the lab humans are the cause of climate change because we as humans produce large amounts of carbon dioxide. We as humans should care about climate science because we want the human species to live as long as possible, and because of climate change we are actively killing our species. Indeed, the climate and temperature have always been changing it is not surprising the world is always adjusting and changing. Nature and humans working together show an increase in temperature because the two of them working together affect the climate. Albedo effect: A surface without snow or ice absorbs more heat, a surface with snow and ice reflects more heat which causes a convection cell as well as wind. Albedo= 1 completely reflects radiation, Albedo=0 completely absorbs radiation, and color is the main influence on albedo. Albedo and continental glaciers: Antarctica now has more than 65,000 meltwater lakes as summer ice melts, because the dark patches of water around the Arctic glaciers are causing the ice to melt because the water is absorbing the heat. Pavement retaining heat during the hot summer days, and releasing it after the sun goes down makes the temperature hotter. The Albedo effect is a feedback cycle, positive cycles amplify conditions, and negative cycles negate effects.
