Understanding Climate Change and its Impacts
Climate change is a complex issue that encompasses various dimensions and has widespread impacts on a global and local scale. At the heart of this issue is the phenomenon of global warming, driven primarily by greenhouse gases, such as carbon dioxide.
Global warming: Global warming refers to the long-term increase in Earth’s average temperature, primarily caused by the excessive emission of greenhouse gases into the atmosphere. These gases trap heat and prevent it from escaping into space, leading to a rise in global temperatures.
Greenhouse gases, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), act like a blanket around the Earth, trapping heat from the sun and causing the planet to warm. Carbon dioxide, in particular, is a significant contributor to global warming. Once emitted into the atmosphere, it can remain there for thousands of years, continuing to contribute to climate change.
Committed climate change: Even if all greenhouse gas emissions were to cease today, climate change would still continue to impact future generations. This is because of the long-lasting nature of greenhouse gases in the atmosphere. The accumulated greenhouse gases from past and present emissions will continue to drive climate change for centuries to come.
The level of carbon dioxide in the atmosphere is currently at more than 400 parts per million, a level not seen in millions of years. To put this into perspective, during the Pliocene Epoch, which occurred around 5 to 2.6 million years ago, atmospheric CO2 concentrations ranged from 350 to 450 parts per million. The increase in CO2 concentration highlights the urgency of responding to climate change and curbing greenhouse gas emissions.
