is one of the most complex issues facing us today. It involves many dimensions – science, economics, society, politics and moral and ethical questions. Most climate scientists agree the main cause of the current global warming trend is human expansion of the “greenhouse effect”. The green house effect is explained by NASA as the effect that occurs when sunlight passes through the atmosphere and warms the Earth’s surface. This heat is radiated back toward space. Most of the outgoing heat is absorbed by green house gas molecules and re-emitted in all directions, warming the surface of the Earth and the lower Atmosphere. The green house effect acts as a thermal blanket for the Earth, absorbing heat and warming the surface to an average of 15 degrees Celsius (59 degrees Celsius).
The role of human activity
There’s a more than 95 percent probability that human activities over the past 50 years have warmed our planet. The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to 400 parts per million in the last 150 years. The panel also concluded there’s a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane, and nitrous oxide have caused much of the observed increase in Earth’s temperatures over the past 50 years.
Reducing climate change
involves reducing the flow of heat-trapping greenhouse gases into the atmosphere by reducing sources of these gases. The goal is to avoid significant human interference with the climate system, and “stabilize greenhouse gas levels in a timeframe sufficient to allow ecosystems to adapt naturally to climate change, ensure that food production is not threatened and to enable economic development to proceed in a sustainable manner” (from the 2014 report on Mitigation of Climate Change from the United Nations Intergovernmental Panel on Climate Change, page 4).
Take local action
Climate change is an international and global concern. Our governments, industry leaders and NGO’s are coming together to take action on reducing climate change. But climate change is also a local responsibility that we as humans need to take responsibility for.
