An HFC gas is a gas which can be used in a number of different applications. HFCs are commonly seen in use, for example, as propellants for aerosolized solutions, and as refrigerants in cooling systems such as refrigerators. These gases are produced by a number of chemical companies around the world. Use of HFCs began rising rapidly at the end of the 20th century, for reasons which will be discussed in more detail below.

HFC stands for hydrofluorocarbon. These gases contain a mixture of elements, with prominent amounts of carbon, hydrogen, and fluorine. HFC gas was originally proposed as a viable replacement for CFCs, chemical compounds which scientists realized were having a profound impact on the ozone layer. Rising CFC use led to depletion of the ozone layer and global concerns about the Earth's environment. These gases were restricted and in some cases banned, necessitating the development of a replacement.

Initially, the use of HFC gas as a replacement seemed very promising. These gases did not have a documented impact on the ozone layer, which led people to conclude that they would be safe for use in large numbers. However, researchers realized that in replacing CFCs with HFCs, they had actually created another problem. HFC interacts with greenhouse gases to contribute to global warming, and it is unfortunately highly effective when it comes to acting as a greenhouse gas.

Researchers cautioned that the rise of HFC gas use could complicate the global warming problem recognized at the end of the 20th century. Warming could have a variety of potentially serious impacts, as even small changes in temperature can trigger huge shifts in climate. Warming trends could lead to severe weather, problems with crops, and many other problems. For this reason, HFC gas and other gases which contribute to warming are a cause for concern, with scientists trying to balance human needs with environmental safety.

Alternatives to HFC gas are being explored by researchers. Scientists would like to avoid the mistake of hastily selecting another alternative to a dangerous gas, only to find out that the alternative also causes problems. As a result, they are proceeding with caution, while working with companies which make and use HFCs to talk about ways to reduce their release into the environment, reduce the needs for the use of such gases, and address the environmental harm caused by gases which contribute to warming, ozone depletion, and other problems with the Earth's atmosphere.

Science can be flawed, but I still have faith that through science we will be able to develop a better future. In the long run, science always tends toward progress. There are accidents, mistakes, failure and sometime tragic consequences, but science has irrefutably improved the lives of everyone on the planet. I believe with every ounce of my being that science will rise to the challenge of climate change and engineer a path for humanity moving into the future

@zsazsa56 - I have to respectfully disagree with just about everything you said. Let me start at the beginning

While there are dissenting scientists, the vast majority of the scientific community believes in climate change and has advanced compelling evidence to suggest that it is as big a problem as we have been lead to believe. Science is always a guessing game, but you can not ignore the mountains of scientific evidence suggesting that climate change is real.

HFCs are not the only thing that causes global warming, but they are one thing along with fumes from industry, agricultural waste and emissions from cars. HFCs, along with a whole host of other man made products that are released into the atmosphere each day, combine their effects to alter the earth's climate.

Development is a real problem. We should try to expand prosperity but we should all, especially those of us in the developed world, work to consume less and to use our resources more responsibly.

I think climate change is still up for debate. There are a number of respected scientists who have advanced powerful theories suggesting that global warming will not be such a problem.

The demonization of substances like HFCs is one example of how these ridiculous theories gain traction. To think that the gas in my can of shaving cream will contribute to the collapse of the world seems a bit much to me.

This article is a fine example of the dangers that science poses. We have a tendency to think of science as primarily good, or at least mostly good, but science, like most things has as much potential to harm as to help.

This article contains 2 examples of science run amok. Both CFCs and HFCs have been shown to reduce the ozone layer and contribute to global warming. The solution to one problem ended up being just as bad as the original. In spite of this, the use of HFCs is still ubiquitous.

We should read this as a cautionary tale of what can happen when we trust too much in science, or when we support and idea without knowing all of its consequences. In the future I hope that we can investigate the consequences of our actions further before we put so much emphasis on destructive technologies.
