We are seeing many terrible pictures from Houston as a result of Hurricane Harvey. People with young children and pets are wading through high water in the hope of being rescued by boat or helicopter. Elderly people in nursing homes are sitting in waist high water waiting to be rescued. It's a pretty horrible story.
One thing we can feel good about is that because the United States is a wealthy country, we do have large numbers of boats and helicopters and trained rescue workers able to assist the victims of the storm. We also have places where we can take these people where they will have shelter, as well access to food and medical care. However, how bad the human toll will be from Harvey, it would be hugely worse without these resources.
"Allowing people to emit greenhouse gases without paying for the damage done is like allowing them to dump their sewage on their neighbor's lawn."
This might be a good time for people to take a moment to think about Bangladesh, a densely populated country on the other side of the world. More than 160 million people live in Bangladesh. Almost half of these people live in low-lying areas with an elevation of less than 10 meters (33 feet) above sea level.
Bangladesh experiences seasonal monsoon rains which invariably lead to flooding, as well as occasional cyclones. The monsoon rains and cyclones are likely to get worse in the years ahead, as one of the effects of global warming. This will mean that the flooding will be worse.
Bangladesh does not have large amounts of resources to assist the people whose homes are flooded. It does not have the same number of boats and helicopters and trained rescue workers to save people trapped by rising water. Nor can it guarantee that people who do escape will have access to adequate shelter, medical care, or even clean drinking water. This means many more people are likely to be dying from floods in Bangladesh in part as a result of the impact of global warming.
Emissions of the greenhouse gases responsible for global warming is often treated as a natural market outcome, whereas efforts to restrict emissions are viewed as government intervention. This is nonsense.
Allowing people to emit greenhouse gases without paying for the damage done is like allowing them to dump their sewage on their neighbor's lawn. Everyone understands that we are responsible for dealing with our own sewage and not imposing a cost on our neighbor. It's the same story with greenhouse gases.
It is understandable that a rich jerk like Donald Trump might not want to pay for the damage he does to the world, especially when the people most affected are dark-skinned, but it is not a serious position. The emissions from the United States and other wealthy countries will result in a lot of Harvey-like disasters in Bangladesh and elsewhere in the developing world. We have to take responsibility for this human catastrophe.
