Global warming, a phenomenon that people still do not agree on, is the increase in the earth’s average temperature, especially in the last century. Researches, done by different scientists, show that the earth’s temperatures have risen by 0.65⁰C – 1.06⁰C, a trend that should worry anyone.
Carbon Dioxide Increases
The increase in carbon dioxide in the atmosphere, together with other greenhouse gasses, is a major cause of global warming. The escalation in burning of fossil fuels to generate electricity, and increase in motor vehicles, which leads to the emission of exhaust fumes into the atmosphere, have largely contributed to the high levels of carbon dioxide.
Widespread deforestation in the world (it is estimated that 3-6 billion trees are cut annually, with the number increasing each year exponentially) leads to increase in the carbon dioxide levels, as each tree cut releases the carbon dioxide it had stored into the atmosphere. The carbon dioxide, and other greenhouse gasses in the atmosphere, absorbs sunlight and solar radiation that should ideally escape into space. The trapped heat leads to increase in the earth’s temperatures.
Adverse Effects of Global Warming
Global warming has had adverse effects on the earth. Melting of glaciers has caused flooding of the low-lying regions and rising of the sea level, which results in flooding of coastal regions. Higher temperatures increase the risk, and effects, of forest fires. Global warming, more often than not, has led to unpredictable weather patterns. The menace affects farmers, as it is increasingly becoming difficult to predict the rainy season for planting, or the dry season for harvesting.
That, among others, are the effects global warming is having on the planet, which affect us as human beings as well. It is our duty to safeguard our planet by promoting the use of cleaner fuels that do not emit carbon dioxide, use of clean energy sources such as solar, and planting more trees instead of cutting them.
