Tackling Climate Change

The 3 lecturers gave their views about global warming. Global warming is global issue and therefore we have to respond to climate change. By being fuel efficient, conserving energy, mitigation, adaption and capture and storage of Carbon Dioxide (C02) are ways in which we can do so. There are many actions we can do to save the environment such as the use of biomass fuel replaces petroleum based fuels and the lesser usage of cars.

There had been suggestions to store C02 and the two options are to store C02 in depleted oil or gas field or in the ocean known as ocean storage. I found this idea very interesting as instead of now allowing the greenhouse gases to be diffused upwards. The excess greenhouse gases are now going downwards. Another option is the Geo-engineering option. The atmosphere is well mixed, reducing the C02 content of the atmosphere requires international collaboration, and most of the big emitters have to take part.

There are many potential consequences of global warming. This is very interesting as well as only one problem which most of us do not take seriously can actually lead to many other problems which can affect our everyday lives. Intense storms and hurricanes can occur. Extinctions of animals may occur. There may even be economic and social disruption. The possible effect of global warming is Some areas will benefit from a warmer climate and other will suffer from melting ice, rising sea level and more extreme weather events, increase drought and flood, and shift in location of wildlife habitat and agricultural areas.

Governments will have to play an important role in reducing global warming. Governments can tax greenhouse gas emissions, subsidise energy efficiency and renewable energy use and cooperate internationally and individual and institutions can sharply reduce the greenhouse gas emissions. We can all do our part but it is a known fact that there are many difficulties in dealing with climate change. The difficulties include change can disrupt economies and lifestyles, it will have a long-lasting effect and Impacts are not spread evenly. The basic approach is to drastically reducing greenhouse emissions and develops strategies to reduce its harmful effects.

Renewable Power is now being used as alternative source to traditional such as coal. I find the “rise” of renewable power rather interesting. Politics and Regulatory affects technology. Research was at a low percentage and people used to reject clean or renewable technology. However, economics and marketing cause of change in approach to technology. Competition among countries leads to the rise in technology. Even wars are one of those which contribute to the rise. Imagine without all these factors, we will not have any technology such as renewable power to counter global warming.

To conclude, the points which all 3 lecturers gave were very real issues in today’s world. However, I am very surprised the very first car was an electrically-powered car instead of the fuel-powered car. Global warming could be delayed if only the electrically-powered car was used widely today.
