Understand Global Warming and Its Effects via Home Experiments

by th0ughts on October 21, 2009

Global Warming is basically the increase of the Earth’s near-surface air and ocean temperature relatively higher that average. Climate change however denotes more specificity (although at times both terms are used interchangeably) since it denotes other changes aside from temperature.

Climate researchers have documented almost every incident that they could cite to support the interconnectivity of the current climate situation with those that had been earlier predicted. The only problem is having the ability to precisely determine the extent to which these consequences will occur as they vary by region.

Among the mostly know and highly documented effects include the following:

Excessive Droughts and Massive Flooding


As the weather gets warmer, expect that evaporation occurs on both land and sea. This may cause drought in some parts of the world and the moment that this extra water vapor drops as rainfall, it’ll surely cause flooding. Imagine a big lump of cotton or sponge absorbing water, the more water it takes in the more water it pours. Understand the Water Cycle and you’ll know what it means.

Melting Of Ice and Snow

The melting of ice caps could be a worse scenario but to this day, scientist had been closely monitoring the arctic region. Imagine a glass of water that is marked half full. Try to drop a couple of ice cubes and notice that the water rises above the marking. What does it tell? Simple, if the glaciers in the arctic region melts, icebergs are then likely to float and melt thus increasing sea level. Once it happens, coastal cities will then be at the brink of flooding.

Adverse Weather Conditions


The warmer the weather becomes the more likely I’ll cause heat waves, instances of heavy rainfall and increase in the number of storms more destructive than in the past. If you are actually dumbfounded on how a typhoon or a tropical cyclone is formed, get a glass of water (a clear glass would be ideal) and stir it with a spoon continuously. Notice the whirling motion of the water (vortex) inside the glass and its center which is vacuum.

The center is the point where there is little or no pressure and the surrounding part having tremendous force encircling it. This principle applies to the existing of tropical storms which are often classified as Typhoon or Tropical Cyclones depending on its direction demarcated within the Pacific Ocean from Asia, north of the equator, and west of the International Date Line.

Rising Sea Level

The rise in sea level can happen in two reasons: first, through melting of ice caps and second through Thermal expansion. Thermal expansion could take a long time to take effect but the consequences can be worse. An increase in temperature of two degrees Celsius can cause water level to rise to almost a meter. Thermal expansion is the response of matter due to change in temperature. Imagine filling a casserole with water then bringing it to boil. Notice that as the water starts to boil, you can see slight increase in volume. It tends to meet the pressure on the surface thus spilling over when it reaches its boiling point. Try to cook some porridge and wait for it to boil. The moment it starts to boil, you’ll notice that it rises over the casserole and spill over. These examples are the effects of Thermal expansion. Normally for closed containers, water fills in the space and takes the form and shape of the container that’s why it spills over. It’s the same principle here. Imagine if sea water (covering a huge area) rises to cover the surface?

So there you go, these are my personal take and understanding of Global Warming using simple science principles and home made experiments. If you have any corrections or suggestions that you’d like to add to the post, feel free to leave it at the comment’s section.
