CONCEPT OF GLOBAL WARMING
Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed to be contributing to increases in average global temperatures. This is mainly caused by the increase in greenhouse gases such as CO2, CH4.N20 and CFCs. Climate change affects all regions of the world. Polar ice sheets are melting and sea levels are rising. Some regions experience more extreme weather events and rainfall, while others experience more extreme heat waves and droughts. These impacts are expected to increase in the coming decades. expected to have a number of impacts on the oceans. Current impacts include sea level rise due to thermal expansion and melting of glaciers and ice sheets, and warming of the sea surface, leading to further temperature stratification. Another impact is changing ecosystems and habitats, as weather patterns change rapidly, terrestrial and marine habitats change, making them inhospitable to some species w...
