According to the Mauna Loa Observatory in Hawaii, the carbon dioxide levels in the atmosphere have reached their peak. This past Friday, data showed that carbon dioxide levels are almost 40 percent higher than ever recorded- in other words, there are more greenhouse gases in the atmosphere today than there have ever been in human history. The last time that carbon dioxide levels were this high was tens of thousands of years before Homo sapiens evolved.

Scientists know that humans are the cause of global warming, because of how the increase in climate correlates with the time period of the burning of fossil fuels during the Industrial Revolution. Most recently, countries in the Arctic ocean experienced temperatures that were 30-40 degrees warmer than average last weekend.

Since humans are the cause of global warming, we have to be the ones to make a change. Although we can never truly put a stop to climate change, our actions will definitely slow down the process. Countries such as Iceland, Costa Rica, and France have taken the initiative to change to renewable energy. On a smaller scale, everyone can make their own small changes are sacrifices every day. You can show your support to organizations that focus on sustainability and global warming awareness and can encourage your politicians to vote on eco-friendly laws. Some more ideas of changes that you could make are in the article “Gain an ‘A’ in Eco-Friendly”, written by Wendy Medina.
