For millions of years, the global climate has fluctuated. However, the trajectory of climate change is being drastically altered by humanity. Our accelerated economic development is having a serious impact on the world's climate.
The 2008 Climate Change Act commits the UK to 80% statutory greenhouse gases emissions (GHG) reduction by 2050. The agricultural industry is responsible for approximately 25%, 50%, and 80% of global anthropogenic emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) respectively.
Our early 21st century civilization is in trouble. We need not go beyond the world food economy to see this. Over the last few decades we have created a food production bubble—one based on environmental trends that cannot be sustained, including overpumping aquifers, overplowing land, and overloading the atmosphere with carbon dioxide.
A threat of irreversible damage should prompt action to mitigate climate change, according to the United Nations Framework Convention on Climate Change, which serves as a basis for international climate policy.
