WHAT IS CLIMATE CHANGE?
Climate change is the general change in temperature, rainfall, wind, and other climate patterns over a period of time. We consider the actions of people as a cause of this change. Thus we say that climate change is a direct or indirect result of human activity. The United Nations Intergovernmental Panel on Climate Change (2014) defines climate change as a change in the state of the climate that can be identified (e.g., using statistical tests) by changes in the mean or the variability of its properties, and that persists for an extended period, typically decades or longer. Climate change may be due to natural internal processes or external forcings such as modulations of the solar cycles, volcanic eruptions and persistent anthropogenic changes in the composition of the atmosphere or in
IMPACTS OF CLIMATE CHANGE
The world is already feeling the impact of climate change, with the planet only 0.8 ºC warmer than in pre-Industrialtimes. Many of us could experience theharsher impact of a 2 ºC warmer world within our lifetime, that is, 20 to 30 years from now. And 4 ºC is likely by the end of the century, if the world does not act now.
