Global warming is caused by the build-up of heat-trapping gases, primarily from burning fossil fuels and cutting down forests. This leads to an imbalance in the earth's temperature, causing the planet to warm up. Research shows that since the industrial era, the global temperature has risen by about 1 degree Celsius and is increasing by 0.2 degrees every decade. Human activities, such as burning coal and deforestation, play a significant role in this temperature rise. While natural events like volcanic eruptions also contribute to global warming, the main driver is the way people use energy and alter the landscape. This warming trend has serious consequences for the earth's climate system, with most of the increase in temperatures linked to human actions rather than natural processes.
