Is the subject of greenhouse gases really worth all the attention it’s receiving? Greenhouse gases are increasing at a rate that scientists have never before seen in the history of the planet and record keeping, and there is little (if any) room for debate of this point. So yes, unless levels are managed we could expect to see carbon dioxide concentrations between 75 percent and 350 percent higher than pre-industrial concentrations by the end of the 21st century.What exactly causes global warming? In short, it’s human activity. While a lot of greenhouse gases occur naturally and are necessary to keep the Earth warm enough to sustain life, the human use of fossil fuels is the number one source of excess greenhouse gas beyond what is needed to sustain life. In its most basic form, this increase is from the excessive use of cars and electricity as well as deforestation.Why is there so much attention placed on this subject? If the concentration of greenhouse gases is allowed to grow unchecked, more and more heat will be trapped in the atmosphere which in turn affects the climate in the form of weather patterns which has been indicated as a prime contributor to species extinction, influencing the length of seasons, and causing coastal flooding to name a few severe conditions.Isn’t the topic being blown out of proportion? Absolutely not. Every major scientific institution or agency that studies the historical pattern of the atmosphere agrees that the climate is warming on a rapid and consistent basis and contribute the cause directly to greenhouse gases as created by human involvement. And it’s not just scientists that take this stance. Leading businesses across the globe and across all industries have acknowledged the problem and are taking measures to reduce their impact.So what’s the big deal about rising sea levels? It’s expected that worldwide sea levels will increase by as much as 23 inches by the year 2100 (and continue to rise thereafter) which will cause millions of individuals to flee coastal areas which are now hubs of industry and economy. And this is not a local concern it is global. Environmental migration will occur as a result of rising sea levels, desertification, dried up aquifers, weather-induced flooding and other serious environmental changes that will affect every country of the world.
