From this article, I have learnt what climate change is. It is any long-term significant change in the expected patterns of average weather of a specific region over an appropriately significant period of time. Climate change reflects abnormal variations to the expected climate within the Earth's atmosphere and subsequent effects on other parts of the Earth, such as in the ice caps over durations ranging from decades to millions of years.
I have also learnt many new facts on climate change. I have learnt that Climate Change is the result of a great many factors including the dynamic processes of the Earth itself, external forces including variations in sunlight intensity, and more recently by human activities, which might in future be deliberate geoengineering. External factors that can shape climate are often called climate forcing and include such processes as variations in solar radiation, deviations in the Earth's orbit, and the level of greenhouse gas concentrations.
I have also learnt what glaciation is. Glaciers are recognized as being among the most sensitive indicators of climate change, advancing during climate cooling (for example, during the period known as the Little Ice Age) and retreating during climate warming on moderate time scales. Glaciers grow and shrink; both contributing to natural variability and amplifying externally forced changes.
Through this article, I have learnt many things on climate change and other new facts on it. By reading this article, I hope that I can contribute to the world to stop climate change.
