Climate Change


Climate change is one of the biggest issues that we as a global society face. Yet many do not know of the consequences or simply do not believe the science. Never before has humanity been faced with a problem like the one staring us in the face right now. There are so many unknowns, so many variables. Scientists cannot begin to predict the outcome from all the anthropogenic damage we have done to the planet. This is not to say that it is too late to change. But if change is to be made, society needs to understand what we are up against. This is not a problem to be brushed off in the hope that someone else picks up the slack. This is a global issue and only the global community will we be able to reverse and overcome it. But people who disbelieve the science of climate change need to understand the problem and what could happen should it go unchanged.
            The recent severity of hurricanes clearly illustrates the threat of climate change. The scientific data is there and shows a positive correlation between climate change and an increase in hurricane severity.
To date we have seen an increase in hurricane severity in the Caribbean. This is due to a slight increase in water temperature. As the warm seawater evaporates it condenses and releases energy, which powers the hurricane. An increase in water temperature will allow for the hurricane to increase in strength before making landfall. Closer to home, Hurricane Katrina showed the United States the devastation such hurricanes could wreck on a region. And it was only a preview of what is to come.
Imagine a world where hurricanes of that caliber or greater become commonplace. People will be displaced. Land will become uninhabitable. Cities will become economically unviable and populations relocated elsewhere.
Researchers have gone out into the field and taken baseline data of many potentially susceptible locations, such as Kingston, Jamaica; Fiji; and Tonga.[1] They put dollar amounts on buildings, roads, highways and other infrastructure, as well as crops and ecosystems. They have the estimated the costs and now must ask the questions. Do the costs of allowing climate change to go unchecked outweigh the benefits of ignoring and denying its existence? Does emitting our current level of greenhouse gases outweigh the costs of the lives that will be affected by an increase in hurricane severity?

  1. I strongly agree with your opinion on the seriousness of climate change. However, I think one of the reason for so many people to not believe in climate change is that no one really knows what the exact or even the major cause is. In order to make people act to the climate change, strong scientific evidences are extremely important. This evidence need not only to proof the climate change is true, it also need to proof that it is caused majorly by human activities. I attended a seminar on climate change. The speaker is one of the top scientists in the field. However, he said that more and more evidences are pointing to other natural causes instead of human activities for the climate change. I believe that human activities can make a difference, what do we need to do in order to make people act without strong scientific supports? I think this is a more effective question than trying to convince people with unsupported hypothesis.
