Does the government and do scientists have special responsibilities to coastal dwellers in the context of global warming?
You say that you are not familiar with global warming, so I will start with a brief explanation of the phenomenon that can help you to answer the question about the responsibilities of the government and scientists.
The idea of global warming is that our planet’s climate is getting warmer and that it is doing so because of human activity. It is believed that the carbon dioxide that we put into the air, mainly through the burning of fossil fuels, is trapping more of the sun’s heat inside the atmosphere, thus warming the planet. If the planet warms up enough, the ice caps at the poles will shrink. This will mean that the water locked in those ice caps will be released into the oceans. This will cause a rise in the level of the world’s oceans.
In such a situation, people who live near coasts (and those who live on low atolls such as those in the Marshall Islands) will be impacted. Rising oceans might flood the places where these people live. In my view, governments would have a special obligation to those people. It would be the duty of the government to help them move to places that would be safe (or to try to do things to make it safer to live where they are) since the danger to them is not something that is specifically their fault.
For this reason, I think that the government (and scientists) has a special responsibility to help coastal dwellers deal with global warming.
