According to the National Oceanic and Atmospheric Administration, July 2023 was actually the hottest month ever recorded on Earth. The heat wave caused hundreds of deaths, thousands of hospitalizations, and billions of dollars in damages. It also exacerbated droughts, wildfires, and power outages. 

The culprit behind this unprecedented heat is climate change, driven by the accumulation of greenhouse gases in the atmosphere. The most well-known greenhouse gas is carbon dioxide, which comes from burning fossil fuels. Often overlooked is methane, which accounts for about 16 percent of global greenhouse gas emissions and has more than doubled since pre-industrial times. 

Robert Stavins, PhD ’88, says that reducing the amount of methane in the atmosphere is a critical and cost-effective way to slow climate change and its impacts. To get there, the AJ Meyer professor of Energy and Economic Development at the Harvard Kennedy School is leading a new initiative at the University’s Salata Institute which aims to reduce methane emissions from different sectors using innovative approaches and collaborations. If successful, he says the world can “bend the curve” on climate change, giving humanity desperately needed time to address the larger, long-term problem of carbon dioxide.
