Combating Climate Change
Climate change is a real problem that is continually getting worse. Reduced crop yields, rising sea levels, more intense storms, reduced hydropower production, and reduced water quality are just some of the problems that are rooted or at least partially rooted in our changing climate. This problem is one that has existed for quite a while but is getting worse and worse. Climate change started with the onset of the industrial revolution, where coal started to be burned for machines in factories. Since then we have been burning more and more fossil fuels, as well as added to the copious amounts of greenhouse gases being pumped into the atmosphere hydrofluorocarbons. The world has emitted 50% more carbon dioxide since 1990.
If this continues the world may experience a food shortage. Each degree that the world warms by reduces farming efficiency by 5%. From 1981 to 2001 that meant 40 megatons of food per year. The rising oceans also pose a problem to food production. Much of the world’s arable farmland is somewhat near the coast. The sea rose almost 20 centimeters in less than a decade. Should this continue, a lot of farmland may become too much salty to grow most crops.
Not all is lost though. There are many groups attempting to find solutions to climate change. In 2015 the U.N. adopted the Paris agreement to slow down climate change, the U.S. department of energy is working to reduce our dependence on fossil fuels, and many countries around the world are replacing the hydrofluorocarbons in refrigerators with non-greenhouse gas ones. We as individuals can help as well, by simply conserving energy, we can save the world from a lot of trouble in the future.
