Reversing Climate Change with Geoengineering

by Sanjana Kulkarnifigures by Jovana Andrejevic The average global temperature is increasing faster now than at any time in the last 2 million years. This has fueled record-breaking droughts, heat waves, and wildfires, and has intensified weather patterns, causing more extreme and damaging hurricanes and rainfall. Human activity is driving this change, primarily through the emission of carbon dioxide (CO2) and other greenhouse gases, which … Continue reading Reversing Climate Change with Geoengineering

Flurries of “marine snow” could help keep the planet cool

Far below the ocean’s surface, millions of tiny particles fall through the water like a scene from a snow globe. But this isn’t anything like normal snow; this is “marine snow,” debris from tiny dead organisms like plankton and algae that floats down to the deep sea. Because carbon is one of the main chemical elements in living things, the ocean floor becomes coated in … Continue reading Flurries of “marine snow” could help keep the planet cool

Biomass over Coal: Burning Different Carbon to Mitigate Climate Change

by Jordan Wilkerson figures by Daniel Utter Ever since the Industrial Revolution around 150 years ago, most of the electricity used in the United States has come from burning fossil fuels. These fuels, such as coal and oil, are all made of carbon. They’re such an important form of the element that the name “carbon” comes from the Latin word for coal. However, burning all … Continue reading Biomass over Coal: Burning Different Carbon to Mitigate Climate Change
