Causes of Climate Change

Over time, Scientists have studied the climate of the earth by examining a variety of indirect impacts of our climate through ice cores, tree rings, glacier sizes, pollen spread, sea sediments, and studying adjustments in the earth’s orbit around the sun. Their findings reveals that the climate changes naturally over large periods of time, but these changes does not clarify the studies of the increase in global warming that we have been experiencing over the last 80 years. That is why “…it is extremely likely (> 95%) that human activities have been the dominant cause of that warming up [the planet]”. REFERENCE

Human activities have contributed considerably to climate change via:

Greenhouse Gas Emissions

– Reflectivity or Absorption of the Sunlight’s Power.
