As the technology is advanced, all the artificial products and buildings damage not only human but also the Earth because they release detrimental pollutants, that make the Earth warm and harm people's health. Especially, carbon dioxide, which is released from the factories, vehicles, and other plastic products, is well-known as the most influential pollutant to warm up the Earth. Due to the environment destroying contaminants, the Earth is getting warm(we call 'global warming') by absorbing ultraviolet rays, the icebergs are melting, and the sea level is increasing right now. There are much more phenomena that are including in 'Climate Change.'

To know more specifically about climate change, I will explain with more details. Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions. It is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant reason of recent climate change.

Evidence for climate change is taken from a variety of sources that can be used to reconstruct past climates. Reasonably compete global records of surface temperature are available beginning from the mid-late 19th century. For earlier periods, most of the evidence is indirect climatic changes are inferred from changes in proxies, indicators, that reflect climate, such as vegetation, ice cores, sea level change, and glacial geology.
