climate change

                    Climate change is a change in the statistical properties of the climate system when considered over long periods of time, regardless of cause. Our earth's climate is changing through a natural cycle. It may be change in average weather condition, or in distributions of weather around the average conditions. It may cause by factors that includes oceanic processes such as oceanic circulation, variation in solar radiation received by earth plate tectonics and volcanic eruption, and human-induced alternation of the natural world ; these later effects are currently causing Global Warming, and climate change is often used to describe human-specific impacts.
                    The green house effect is a natural mechanism that retains the heat emitted from the earth's surface. It is cause by a range of different gases in the earth's atmosphere. And there is a big evidence that the bad effects of our surroundings is cause by us humans. Like burning the trees in the forest, burning plastics that may cause out atmosphere destroyed. 
                    Climate Change and other bad effects that are happening in the world is because of our bad doings. It is also the biggest challenge and problems that the next generations of people will also solve for them. So , for now we should stop doing that things because maybe because of that activities that we are doing maybe the reason why our surroundings and atmosphere will be destroyed.
