Climate change impacts are already being felt in the United States and around the world. The latest International Energy Agency (IEA) report confirms that energy-related carbon dioxide emissions hit an all-time high last year.
Is it time to give up on reducing emissions? Absolutely not.
Better to Pursue Climate Action Now
While things may look bad today, unchecked global warming will exponentially increase the human and economic toll of responding to a permanently altered planet. A recent report from the World Bank outlines the devastating effects of a global temperature rise of 4 degrees Celsius (7.2 degrees Fahrenheit) above pre-Industrial levels: flooding of coastal cities, risks to food production, unprecedented heat waves, increased frequency of killer storms, and more. This is not the future that we want to leave our children and grandchildren. Nor can we simply adapt to this future – even if we wanted to.
The IEA makes it clear that acting now will be less costly than waiting until later on. We should be moving toward a low-carbon future, investing in low-carbon energy systems, and preparing our infrastructure for oncoming climate impacts. According to the IEA, delaying action would increase the costs by having to retrofit energy sources and risking their becoming obsolete. The IEA lays out four sensible measures that countries can undertake to curb growth in GHG emissions by 2020—and which come at no net economic cost.
