Climate change

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.

Climate change is caused by factors such as biotic processes, variations in solar radition received by Earth, plate tectocnic and volcanic eruptions. 

Certain human activities have also been identified as significant causes of recent climate change, often referred to as global warming
