Global warming- some say that humans are the cause, while others debate that it’s simply a natural phenomenon, a 1500-year-cycle that has been going on for the past million years. As far as I could remember, global warming and man-made CO2 and other greenhouse gases have been taught as one topic. We were taught that all of the polar bears were losing their homes because of our cars, factories, and more. But now, that I know about the natural cycle that has been occurring the whole time, I believe that the cause for global warming is both. Some statistics say that there is a 66% chance that humans are the cause of global warming, while others say that only 0.28% of the greenhouse effect is caused by human activity, not including water vapor and the percentage of anthropogenic, or man-made green house gases is 3.298%, not including water vapor. Just by comparing different results of different sources, you can tell right away that this is a greatly debated topic. Also, none of the sources really state that their information is 101% correct; they’re all theories.
Although this blog assignment was to answer yes or no, to state whether or not I think it is us humans that is causing global warming or not, I cannot answer this question (sorry Mr. Ullrich, I’m an indecisive person…). Up until this point, I have never doubted nor have thought twice when people said that humans were the cause of global warming, and that it is we that much change in order to balance our earth’s climate changes again. But now, although I still think us humans are a factor of the rapid increase of temperatures, I also think it is just another natural phenomenon that we cannot avoid.

Basic Information-

Mass: 300 to 400 billion solar mass (approximately the mass as the Milky Way Galaxy, if not less)
Size: approximately 228,000 light years in length of the disk, and 100,000 light years high (larger than the Milky Way Galaxy)
Visual Magnitude: 3.4
Other Names: Messier 31 (M31), NBC 224, The Little Cloud, The Great Nebula

The Andromeda Galaxy is the nearest spiral galaxy to the Milky Way (2.5~2.9 million light years away). It is also said to be the largest of the 30 galaxies in the Local Group, containing up to a trillion stars. It can be seen with the naked eye from planet Earth.
It was first found by Abd Al Rahman Al Sufi, a Persian astronomer, in A.D. 964. He described the Andromeda as “The Little Cloud.
The Andromeda Galaxy was named after the mythical princess Andromeda, after being spotted in the Andromeda Constellation.
Studies say that the Andromeda Galaxy may have two nuclei, and this may be due to another galaxy that was cannibalized a long time ago, or it may be that there is a single core partly obscured by dust.
What I find interesting is that the Andromeda Galaxy is predicted to collide with the Milky Way Galaxy in approximately 4.5 billion years from now- but it most likely will not effect the Earth in any way, we will be long gone by then, and the human species itself may be extinct as well.

Hi, my name is Natsu, and I am an 8th grader in New York. I moved to to the United States from Tokyo, Japan when I was 5 years old, and have stayed here ever since. My favorite food is sushi; which isn't that much of a surprise for a Japanese person. Being the lazy person that I am, in my free time, I love to sleep and to read. I have two siblings; an older sister, and a younger brother, who I can proudly introduce as a five year old cancer survivor- because that's exactly what he is.
I hope you all enjoy my blog!
