Answer:
By definition, climate change is an average long-term shift in weather patterns that is manifested by altering in the contributing factors including precipitation, temperature and pressure among other indicators. Climate change can be a consequence of a modification in variability typified by extreme weather conditions, for example, erratic rainfalls that cause floods.
The earth’s climate is synonymous with this variability, however, its long-term climatic state is harmonized by the energy balance “between the incoming and the outgoing energy”. As such, any external factor (climate forcers) affecting this energy balance may lead to climate changes.
Importantly, these factors occur in different time periods. Hence, the factors that affected climate change centuries back may not be the ones standing currently.
Climate forcers can be categorized into two groups including human and natural causes. In addition to the duo, there are other changes that happen internally within the climate system, affecting the climate either as short-lived or long-lived. These modifications may be attributed to the atmospheric circulations among others factors
Climate has been changing to the worst since the era that is called the industrial revolution. On analyzing the trend of the world’s mean temperature dating back to the 19th century, one can underscore the fact that, indeed, the Earth is experiencing global warming.
In the 1960s, though, there was compelling evidence of a shifting trend where experts reported that the planet was cooling. Nevertheless, new findings stipulated that this was a brief interruption and the trend would assume the previous modification process in the 1970s.
These findings elicited a serious debate among climatologists with some predicting a sustained cooling trend over time. To this end, they cited a phase of a sustained natural cycle or perhaps the elements of smog and dust particles that continue to fill the atmosphere due to human activities.
