Global Warming in the twenty-first century will cause more natural disasters than in previous centuries, and if you require any further prove it is staring at us right between our eyes. Virtually all countries in the world, both developed and undeveloped have recorded flash floods in the past decade. $billions worth of property have been destroyed due to floods in just the past few years, and scientists are warning us to expect more of it. Not only floods but devastating heat waves, storms and massive climatic changes which will cause our deserts to grow due to desert encroachment, our sea levels will rise, and climatic migration will become the norm of the day.
Global Warming, according to the Collins English Dictionary, is the gradual rise in the average temperature of the earth surface. It is a result of harmful chemicals known as greenhouse gases such as carbon (IV) oxide, water vapour, ozone, methane, and nitrous oxide released into the environment through human activities such as pollution from car exhaust, burning of fossils fuel in industrial plants and deforestation e.t.c. These chemicals in the atmosphere combine to radiate solar energy in all directions on the earth surface, hence increasing the earth temperature in a process called the greenhouse effect. Global warming has been in existence for centuries, but its results are more visible in the present century because of an increase in industrial activities.
During the 18th century, the effects of global warming were minimal, but the phenomenon experienced a sudden rise between 1880 and 2012 increasing the temperature of the earth by approximately 1.1 degree Celsius, and it is expected to multiply by four by the dawn of next century. Apart from the increase in temperature, the effects of global warming include increased precipitation, extinction of some plants and animals, a shift in agricultural cultivation pattern, and rising sea level. In all results, rising sea level is more visible, chronic, and rampant all across the globe because about 71% of the earth's surface is water.
Rising sea level is a phenomenon which describes the increase in the height of water in natural water bodies. The condition gets worst and more alarming when sea banks can no longer hold the tides of the ocean, causing localised flooding of neighbouring habitats. This situation became more noticeable at the start of the 20th century which received a gradual rise of approximately 16cm to 21cm which is far higher than what has been recorded in the past centuries, and according to an Intergovernmental Panel on Climate Change(IPCC), our seas will rise by approximately 90cm by the end of this century.
The above is just a short description of what Global Warming due to Climate change is.
