Abstract: Many scientists, engineers and ecologists are raising profound concerns about changes in the world's standard climate. There is continuous use of fossil fuels as a source of energy. When combusted, gasses such as carbon dioxide, methane and nitrogen oxides are emitted that cause global warming. Deforestation also contributes to hotter temperatures. The threat of global warming is always causing the Earth's climate the greatest harm. Nonetheless, most people do not know about climate change and do not remember that it will be a major trouble in coming years. What the majority do not recognize is that worldwide warming is presently occurring, and we're already experiencing some of its Withering effects. It is and could critically affect ecosystems and disturb ecological balance. Because of the treacherous results of worldwide warming, a few solutions ought to be devised. The paper introduces global warming, elaborates its causes and dangers and provides a few answers to clear up this hot problem. The majority do not know that global warming is taking place now, but some of its weeding results already are happening. Ecosystems are and could be influenced critically and ecological equilibrium could be disrupted. A few solutions should be created because of the dangerous effects of global warming. The article presents global warming, details its causes and hazards, and gives some answers to the hot issue. Chance strength assets (sun, wind, hydro, geothermal, biomass) in particular, would like to be followed significantly. One strategy for mitigating the increasing global warming progress is the location and use of renewable energy sources.
