Climate Change Spells Food Disaster

climate change effectsThis is a subject matter that I’ve been avoiding for weeks. It is actually a broad topic and writing about it means delving into a smörgåsbord of issues that have been addressed by world organizations, media groups, environment advocates, and governments in the past. I will not pretend to be an expert on the matter but I will write what I’ve read about, what I know, and will give my humble opinions.

Climate change is something that we all have heard about but not all of us really understand what it means and how it will impact the world we live in. Unfortunately, the effects of climate change is already bearing down upon us whether we understand it or not. The effects are here, in the guise of droughts and floods. Though both are equally important and are worthy of discussion, tackling the effects of climate change on world wide flooding will be the focus of this article.

Floods in general causes millions, if not billions, of dollars in damages in a year. The amount of flood damages will continue to increase every year as long as we fail to address the problems of drastic climate changes.

Today, regions located in the mid and higher altitudes are experiencing increase rainfall attributed to global warming. The increase in rainfall can cause a myriad of problems to the low landers including, but not limited to, frequency of flash floods, changes in direction and size of various river and other water ways, and changes in the catchment areas where excess waters from the highlands are collected, absorbed, and retained. Increase rainfall means more water trickling down these catchments resulting to water being retained for longer periods of time. This can result to spillage of water out the catchments causing flash floods.

Moreover, as world temperature rises, rain storms and flooding will only get worse. The warmer the Earth becomes, the more water is evaporated and turns into rainfall. Increase rainfall can cause floods as we have witnessed in recent news of flooding in Europe due to continuous rains.

Plus, there is the issue of melting polar ice caps. Increasing temperatures have melted a huge portion of the Arctic ice. Without the polar ice to naturally cool the Earth, global warming is being accelerated. Also, the melting ice and glaciers contribute to rising sea levels.

It has been estimated that by 2100, the world’s seas would have risen by as much three feet. This means massive coastal flooding, beach erosion and causing massive sinking of the world’s land mass including important coastal wetland and barrier islands.

But more importantly, the rising sea level will flood coastal communities and low-lying areas will find themselves six fee below sea level. Such areas include those along the Gulf of Mexico as well as estuaries like the Chesapeake Bay, and not to mention that coasts of Louisiana, Texas, Florida and North Carolina.

So what can we do? Sadly, we know what should be done. We knew about the reasons for global warming, melting polar ice, and rising sea levels for a while now and yet we continue going down the path of disaster. The first thing that should be done is to invest and adapt renewable energy instead of fossil fuels that throws harmful gases in to the atmosphere.
