Understanding Global Warming

The most debated topic on earth is the issue of climate change. This a universally accepted statement. The system of the seasons is changing, and climatic conditions have become unpredictable. Nonseasonal rains are being experienced, the earth is getting warmer, glaciers are melting down, and the sea levels are rising. Fertile lands are becoming infertile and diseases are spreading, some fear that life as we know it will be ending soon, just  imagine what actions must be taken now to save our planet for next generations.

Who do you think is the culprit of these current situations? Well, in fact it is us, as we are all humans, aren’t we? It is our own activities that have resulted in the current situation.

So the following questions might come to everybody’s mind

1. What is it that we have done?
2. What are the effects on our environment?
3. How do environmental changes relate to Climate Change?
4. Can we do anything about it?

Save-Electricity

To answer the above questions, we need to identify and understand the causes, says Ales Rades from Educate the USA. This will help people appreciate the real problem and allows us to work on solutions.
Basically, in nature there is a group of gasses called “Green House Gases”, for instance water vapor , carbon dioxide and some other gasses. Ironically, the presence of these gasses in the earth’s atmosphere is a prerequisite for life on earth. In fact,  these gasses have been helping to regulate the temperature on Earth for ages. These green house gasses absorb reflected solar heat radiation from the earth’s surface and thus prevent the average temperature of the earth to get too cold.

This process is called the “Green House Effect”.

Interesting is that without this green house effect, the Earth’s average temperature would have been – 18 degrees C instead of its + 14 degrees C. It is one of the earth’s natural processes, without which the Earth would possible be uninhabitable.

So, what’s the problem now? 
For over the last century, human activities were directed against nature in such a way that they have become disastrous for our future, and this had lead to the effects discussed in the beginning of this page. Before the industrial revolution, carbon dioxide concentration was 280 parts per million per volume ( PPMv), but currently the level is nearing 400 PPMv. If this rate continues, it won’t be long before the Carbon dioxide concentration would be 490 to 1260 PPMv according to an IPCC special report, and this incredible situation might threaten life on earth too.

Is our earth really warming up?
Yes. There has been an increase of 0.6 degrees C since the late 19th century, and the last 25 years we have seen an increase of 0.2 to 0.3 degrees C. Moreover, the warming is not uniformly spread out all over the world, and an interesting thing is that some places are getting warmer while some other getting colder. However in general, the temperature is rising.

Conclusions & Reasons for Global Warming

  1. Thermal Power Generation
    • Usage of coal is reducing fossil resources, and burning of coal increases the pollution.
    • A solution might be using renewable energy sources for power generation. Example: Wind and Solar power.
  2. Automotive Applications
    • Use of automobiles contributes severely to global warming. Solution: electric cars.
    • Exhaust emissions increase the effect of green house gases.

Global Warming is now and here now and it is high time to act against it. Every single individual needs to participate in fighting global warming. Global Warming threatens us all, regardless of nationality, community, race or culture. Find more information about global warming and how to teach about it here.

Tips for individuals to control Global Warming:

  • Replace your bulbs by fluorescent or energy saving lamps. Fluorescent lamps consume lesser power compared to regular lamps.
  • Use Solar devices for heating. i.e. Solar Cookers for cooking , Solar heaters for Heating etc.
  • Turn of computers when not in use. Don’t keep your laptops in standby mode , shut down when not in use.
  • Always check your car tires. Low pressure tires require more fuel.
  • Walk or ride a bike, but don’t drive for shorter distances. This is good for health and is cost-effective too.
  • Save paper for saving trees. For example, ask for electronic bank statements rather than paper. This saves trees.
  • Grow as many trees as possible.
  • Use public transport as priority which reduces the level of pollution rather than self driving your personal vehicle.
  • Get your vehicle pollution checked periodically.
  • Switch to solar and wind power.
  • Stop the usage of plastic bags.
  • Use energy conservation devices – such as sensor controlled lamps, automatic off for fridge once internal temperature reaches some level, similar type water heating equipment.
  • Use and advice electrical vehicles which will undoubtedly reduce pollution levels.
  • Educate others. This is super important. On every level of education students should be aware of effect of global warming, continues the editor of http://educatetheusa.com/
