Today’s most daunting challenge
Today, the phenomenon of climate change has become one of the most critical global issues, and is soon going to be the biggest challenge faced by the humans. Some of the drivers of climate change include deforestation, infrastructural developments, transmission of increased CO2 emissions, burning of trash, growing number of vehicles and setting up of automobile workshops and dumping.
Causes and effects of climate change
Human activity from pollution to overpopulation is driving the earth’s temperature up and is fundamentally changing the world around us. It is basically called the greenhouse effect – warming which results when solar radiation is trapped by the atmosphere. Gases in the atmosphere such as water vapour, carbon dioxide, nitrous oxide, methane and chlorofluorocarbons (CFCs) are the biggest sources of global warming. The more greenhouse gases in the atmosphere, the more heat trapped, thus strengthening the greenhouse effect and increasing the earth’s temperatures. Human activities like the burning of fossil fuels have increased the CO2 levels, especially since the Industrial Revolution. The rapid increase in the greenhouse gases in the atmosphere had been warming the planet at an alarming rate. While earth’s climate has fluctuated in the past, atmospheric carbon dioxide has not reached the levels it is touching today. Climate change has consequences for our oceans, weather food and health.
Ice sheets such as Iceland and Antarctica are melting. The extra water is causing sea levels to rise and spills out of the oceans, thus causing floods in more regions.
Warmer temperature also makes strange weather patterns. This means not only more intense major storms, floods and heavy snowfall but also longer and heavy droughts. These changes in weather are the real challenges.
