Fossil fuels; such as coal, oil & gas; are by far the largest contributor to global climate change, accounting for 75% of global greenhouse gas emissions and nearly 90% of all carbon dioxide emissions. As green house has emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change. The world is now warming faster than at any point in recorded history. Warmer temperatures over time are changing weather patterns and disrupting the usual balance of nature. This poses many risks to human beings and all other forms of life on earth.
