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

Can converting methane into CO2 help reduce climate change?

Greenhouse gases, such as carbon dioxide (CO2) and methane, contribute to global warming by slowing the rate at which heat energy escapes into space. Although methane is less abundant than CO2, it is several times more potent, absorbing up to 36 times more energy than CO2 over a century. Last year marked the first time that global methane concentrations reached levels 2.5 times greater than … Continue reading Can converting methane into CO2 help reduce climate change?

How Electric Cars Can Become Truly ‘Green’, Once and For All

by Ankur Podder and Rhea Grover figures by Jovana Andrejevic Electric Vehicles (EVs) were once regarded as hopeless, tasteless, and incapable of replacing the fossil fuel-powered vehicles. In 2006, the award-winning documentary “Who Killed the Electric Car?” illustrated the impending obsolescence of EVs after a series of failed experiments by the automotive industry. The predicted doom didn’t stop environmentalists from pressing for the industry to make better EVs, … Continue reading How Electric Cars Can Become Truly ‘Green’, Once and For All

Fossil Fuel Companies Invest in Removing Carbon Dioxide Directly from Air

In the Canadian town of Squamish, there’s a small building with a massive fan on its purple roof. The fan is rapidly pulling outside air into the facility. The air enters the outdoors again, but it’s not quite the same. About 75% of the carbon dioxide (CO2) is gone. Run by the company Carbon Engineering (CE), the building is the pilot plant for their technology … Continue reading Fossil Fuel Companies Invest in Removing Carbon Dioxide Directly from Air

Recycling Carbon Dioxide with Copper Catalysts

The Earth is undergoing climate change due to human activity. One facet of this change is the Greenhouse Effect, where molecules in the atmosphere trap heat, resulting in globally increasing temperatures. Carbon dioxide is a molecule produced in dangerous amounts by activities like farming and burning fossil fuels. Thus far, sustainably converting carbon dioxide to useful chemicals has been difficult, but scientists at the Lawrence … Continue reading Recycling Carbon Dioxide with Copper Catalysts
