The subject of the day was global warming and we had three guests whom gave us an insightful look of the present situation and direction that we are heading in saving our Earth.
The first speaker, Professor Adam Palmer, mentioned that the scale required to change the mindset of the people is too large a number to make a significant difference in reducing carbon dioxide output. In which he introduced a new concept, relatively new to me, of reducing the carbon dioxide output into the atmosphere. The method of capturing carbon dioxide and storing it deep under the sea packaged in a membrane bag or what he called ‘sausage of the sea’ was quite fascinating and new to what I have heard and learnt so far. However he too mentioned that the realization of this project would be far from reaching a checkpoint when there are more other important concerns besides saving the Earth.
Our second speaker touched on the topic of technology and why it wasn’t well received by everyone. Renewable power and electric vehicles were the two important points he emphasized on; the reasons he gave on why both technologies were not accepted was due to economical challenge with cheaper alternatives, political challenges faced in which there were flawed expectations that did not satisfy the people and cultural challenges of people being resistant to new technologies and the changes they have to make.
The last speaker, Dr. Rajasekhar Bala, covered on the assessment and mitigation of the changing climate; Details on how temperature were taken from ice cores to obtain temperatures from millions of years ago, comparing the values with present temperatures and reminding us of what the consequences of global warming would bring to us. Floods, melting of ice and rising sea levels are what we commonly hear when global warming is involved and the solutions in prevention of global warming by improving energy efficiency and cleaning up the world to help save the Earth.
The world has been providing and sustaining us for centuries; it is time that we do our part to give back what we have taken from it.
