Discussions Discussion Technology solutions for climate change
Tara V-USA, Oct. 5, 2013

Hi everyone! My name is Tara and I’m from California.

While the goal of solely relying on clean, renewable energy resources that lack carbon emissions is a noble one, the reality is that we are not able to derive all of our energy from them at the time being. One technological solution for the vast number of power plants currently burning fossil fuels and emitting a drastic amount of carbon into the air is something called carbon capture and underground storage. To put it simply, carbon capture and underground storage is the process of capturing carbon emissions from factories to send it underground in a pipe for storage in rock formations. The pipes often put the carbon over a half a mile into the ground and routine checks ensure carbon is not leaking back up into the atmosphere. While a lot of controversy surrounds this procedure, I recently read an article where Howard J. Herzog, who has headed MIT’s Carbon Capture and Sequestration Technologies Program for over twenty years argues it is a vital option for the current world.

According to the article, the factories and power plants that carbon capture and underground storage targets could almost reduce global carbon emissions in half if they all embraced it. The major argument against carbon capture and underground storage is that it is too expensive. However, according to Herzog and other researchers it is as expensive as other technologies that will likely not have the same effect it could on a large scale. Regardless, most companies will not go along with the technology at this time as building it raises the price of constructing a power plant by around 80 percent. It is a viable option though as carbon can be stored in the same formations from which it was extracted for our fossil fuels. The amount of space available for this storage is even estimated to store one to four trillion tons of carbon in the United States alone! The technology used to capture the carbon, pre-combustion, post-combustion and post-combustion in an oxygen free environment (oxyfuel) all simple in terms of using chemicals to harness the carbon. The only downside is that it decreases energy output of power plants and factories since energy must be used to gather the carbon. I think this technology overall has great potential to allow us to mitigate the speed of global warming until other technologies and solutions allowing a greater reliance on clean, renewable resources are available. Hopefully, advancements will allow the construction of these systems to become more affordable to build. In the long run, it is certainly worth it to look into making carbon capture and underground storage the norm until better solution for a cleaner future are available.

    Great Analysis, Tara. The above proposition for carbon capture and underground storage i believe is really interesting but only for temporary solution until new technology makes it more cheaper and easy for use. Also, the combination of all new technologies for carbon capture will decrease significantly CO2 emissions.

The Catholic Church and Climate Change:

On January 1, 1990, Pope John Paul II delivered his World Day of Peace message to Catholics around the world, and for that year’s address he lamented a “widespread destruction of the environment.” World peace, he warned, was threatened not only by arms, conflict, and injustice, but by “a lack of due respect for nature.”

John Paul II’s message on that day pointed to a worldwide ecological crisis, and while it did not mention climate change by name his references were clear. “Industrial waste, the burning of fossil fuels, unrestricted deforestation, the use of certain types of herbicides, coolants and propellants: all of these are known to harm the atmosphere and environment,” he said. “The resulting meteorological and atmospheric changes range from damage to health to the possible future submersion of low-lying lands.”

Occupy the Climate Emergency: Buddhist Reflections on Inter-generational Justice

http://www.huffingtonpost.com/john-stanley/occupy-the-climate-emerge_b_1116727.html

Since our time on this wondrous planet is brief, we must consider our responsibility to all those who will come after us, whose well-being will depend on the decisions we make today. Shall we sacrifice our children, their children and the next 50 generations for a zero-empathy corporate state? Or shall we “occupy” this climate emergency instead of denying it — until the urgent truth of our situation is acted upon?
