In my research, I have found some new interesting information about natural global warming that agrees with previous information I have seen. There are two main things that I have found that I would like to add.
One is about exaggerations about the effects of warming and about the effects of cooling in the earth's natural cycles. For starters, I would like to restate that global warming is just one part of a bigger cycle of warming and cooling. According to this link, the past "two thousand years of global history" shows us that warming periods have been good for mankind. For example, it was the cold period called the little ice age that brought about the deaths of so many people in the middle ages. Also in general cooling periods have killed approximately twice as many people as warming periods.
The other is another possible cause of global warming, changes is solar variation. One climate physicist, Mr. Singer, says that all of our climate change can "be explained by the Sun's activity." Apparently, the number of cosmic rays that hit the earth affect the number of clouds that will reflect heat back into space which amplifies variations in the intensity of the sun's rays. While I have not seen evidence for everything Mr. Singer has said, I have also read in several other places about variations in the sun being able to affect global warming. So I think that it is safe to say that global warming is at least partially affected by variances in the sun's rays.

An effect of the warming of the earth is the melting of glaciers and ice caps which raises the sea level. Some cities across the world are increasingly be submerged. What would you propose the citizens and the city as a whole do? It would be quite expensive for all of these people to move and build new houses.
ReplyDeleteWell as for this problem, I do not really know the best solution. If they did not move away, then some kind of barricade like a dam would have to be built on the coastal side of the city to keep it from being damaged from the water. Moving would probably be easier.
ReplyDeleteAlthough, the time where this could become a real problem is still quite a ways off, so if it does happen, more solutions that people have not even thought of today will probably be thought of and used, and will probably involve new technologies (unless of course they do actually just move).
