Article of the Week #?

I found a very intriguing article about a catastrophic but natural disaster that occurred multiple times in the past. A large lake, 1/3 the size of Wales, drained between 8000 to 13,000 years ago, leaving devastating effects on the environment. The climate was affected and also many local animals, causing temperature to drop and rainfall to increase. This was truly an important point in history that we need to see.

I thought that the article was fairly well-written and got some good information out of it. It is amazing to me how a simple natural event could devastate an entire area. However, science shows that it did indeed occur. What can we learn from this and what can we do to prevent it from happening again?

One quote that was interesting to me was this: "This was a massive lake. When it drained, it released around 1150km3 of fresh water from the melting glaciers into the Atlantic and Pacific oceans -- equivalent to around 600 million Olympic-sized swimming pools. This had a considerable impact on the Pacific Ocean circulation and regional climate at the time." I wonder how if it is still around today and if we still face any similar threats. Another quote is this: "The study is important because we are currently concerned about the volumes of fresh water entering the oceans from the melting ice sheets in Greenland and Antarctica and this gives us an indication of the likely effects." I liked this quote because it told about similar things that could potentially have similar results.

Overall, I am left with one question: What do we need to do to stop this from ever happening in the future?
