three ships that accompanied Columbus and his crew in 1492. Recent
research finds that the explorers’ arrival in the Americas may have
contributed to a cooling of temperatures known as the Little Ice Age.

I think that it is so interesting that scientists can make these connections. It all starts with a theory that seems wacky at the time, but after it is researched and tested, it could become probable.
This is a weird blog post. In the beginning, like Jason seemed, it seems impossible that Columbus could help the earth this drastically, but it makes sense the the Americans would flee and their land would be covered by ice. So I say "Thanks Chris!"
I think its is really interesting that things happen a long time ago and we only find out about them now. It shows how many things in the world that have yet to be discovered. And just by looking at the title "Did Columbus Contribute to a Little Ice Age?" you wouldn't think it would be possible. But once you read the article, you understand it.

I thought that article was very interesting how Christopher Columbus did all that to change the temperature of the Earth. All of these connections, as Jason said are so unpredictable and unexpected. Scientists, though are so smart, so no wonder they have done all that. Before I read this I had no clue what it was going to tell me, but now I learned so much! As Luca said, "Thanks Chris!"
I think that it's really interesting that Columbus created an early ice age. I didn't think that that was possible. I wonder if people noticed that the temperature got colder, or it was just went unnoticed because it was a gradual change in climate. Also, I wonder if people did notice, what or how much did they realize? I feel like this article could have been longer and explained how cold it really was.
Columbus and the other explorers never thought about how they might change the earth’s climate when they sailed to the Americas. They just wanted to explore the world. Millions of native Americans died when the Europeans conquered the Americas, otherwise there might not have been a Little Ice Age.
It’s strange that man could affect the earth’s climate so long ago, or that massive reforestation could cause carbon dioxide levels to drop low enough to cause a Little Ice Age. It’s like the opposite of global warming. It’s interesting how scientists can study ice in Antarctica and learn about the atmosphere from the earth’s past. The trapped bubbles are like time capsules. But there are other reasons that could caused the earth’s climate to cool down, like volcanic activity and other natural events. What caused the Ice Age?
I didn't know that one person could make such a big difference. At first it seems way fake, but as you read it starts to be possible. It would be cool if we could do something now, and no one knows about it for 600 years. The world is full of mysteries, and we just found out about one.
Wow! I didn't know that one person could contribute so much to the environment. But, since when he came here the native americans fled, it left lots of land where trees could grow back so it would be good for the environment. I'm surprised we didn't find this out a lot earlier.
I thought that this article was very interesting. At first, like tons of people already said, it doesn't seem real. I can't believe that one person made a difference that big. I didn't think that it was possible, but once I read the article, it could be.
That was really cool. I didn't know that could be possible. Like Jason said, this is a cool connection
I think it is interesting that something from so long ago has just been found right now
