Heating up Earth “Addressing Climate Change: If not now, when?” is this year’s theme for the University of Belize’s earth day celebration. We often hear the word ‘climate change’ but do not know the real meaning behind it. You may have also heard about “global warming” and have used it interchangeably with “climate change” knowing that there is a huge difference between them. In basic terms, global warming is referred to as the average increase in the temperature of the atmosphere near the Earth’s surface which contributes to changes in global climate patterns (Shah, 2013). Climate change, on the other hand, is the distribution of weather patterns over periods of time. This is mainly due to the constant emissions of carbon dioxide, methane and ozone (green house gases) into the atmosphere. Sources of green house gases are factories, industries, cattle, dumpsites, vehicles. Once in the atmosphere, these gases trap more heat, releasing it back into the atmosphere and diminishing the Earth’s protective layer against harmful rays – the ozone layer. Climate change indicators can already be seen occurring in our daily lives. The increased indicators in existence today are: increase in humidity, sea level, and sea surface and land temperatures (European Commission, 2012). The decreasing indicators that are presently seen are: a decrease in snow cover on mountain tops, glaciers and sea ice. All of these indicators lead to numerous problems such as the loss of biodiversity, droughts, floods, agriculture loss, and heat waves which ultimately lead to health problems. Worldwide these effects can already be seen. According to Shah (2013), heat waves kill many people and a perfect example of extreme heat waves can be seen in Europe in 2003, where thousands of people died. Droughts have also been seen in some countries. The most readily know one is the 1970 Ethiopia droughts
