How Natural Gas has Become the Climate Enemy

Coal has long been the greatest climate villain, a carboniferous Darth Vader or Voldemort (I said it). As the environmental movement reenergized with Earth Day 1990 (my freshman year of college), one angle was basically: Let’s at least start by switching to natural gas. According to the American Geosciences Institute, coal can emit from 76% […]

The Focus Shifts to Coping with Climate Change

ICYMI: We just officially hit the global temperature threshold that climate scientists have been warning that we absolutely should not—if we want to maintain a healthy planet. The world has had its first year-long breach of the 1.5-degree Celsius (2.7 degrees Fahrenheit) temperature rise that countries had agreed at the 2015 “COP” conference in Paris […]

U.S. President First Warned of CO2 Pollution in 1965

A “Memorandum for the President” lists “the effects of carbon dioxide on climate” among the most pressing environmental problems of the day. It sounds like a message meant for U.S. President Joe Biden. But the memo is dated January 13, 1965, and the president is the 36th of the United States of America, Lyndon B. Johnson. This newly […]

VC Raj Kapoor Describes How AI Fights Climate Change

Kapoor went on to explain that most companies’ supply chains, rather than their direct outputs, tend to be the worst offenders when it comes to emissions. A company called Muir AI uses existing data to help companies estimate the environmental impact of their supply chains. From there, companies can make small, sustainable changes at each […]

Generous Tax Subsidies for Sustainable Aviation Fuels in the U.S.? Yes, But Details Matter.

One of the Inflation Reduction Act’s key provisions is a powerful tax credit to spark the development and adoption of clean, low-carbon aviation fuels. Climate pollution from aircraft is often overlooked, but if aviation were a country, it would be among the top 10 greenhouse gas emitters. The Biden administration is about to make a […]

7 Technologies for Fighting Climate Change

1. Reengineer Electric Motors To replace a gas engine car, you have to match or exceed it in power. The key to that, today, is motors built with rare-earth metals. With exotic names like neodymium, dysprosium, terbium, and praseodymium, rare earth elements go into so-called permanent magnets. They have persistent magnetic fields and are considered […]

12 Energy Dilemmas the World Needs to Address

1. Even clean energy involves environmental harm. Midwestern residents may find land-based wind turbines (a prime green power source) to be a terrible  eyesore. Native Americans are fighting plans for a vast lithium mine on sacred land. The conversion to more (ultimately cleaner) electric cars and households requires building more transmission lines through neighborhoods. Should these […]

The Inflation Reduction Act Could be the New, New Deal

For businesses, the carrots are even more significant. “This legislation can catalyze an entirely new set of climate-friendly industries,” says tech and climate journalist and Techonomy founder David Kirkpatrick. The Brookings Institution calculates that, by 2030, the IRA will help reduce U.S. CO2 emissions about 40 percent below 2005 levels. “This is a business-first approach to government climate action,” […]

Oppenheimer’s Legacy: Nuclear Energy?

During the Eisenhower administration, groups like Atoms for Peace were created with impetus from J. Robert Oppenheimer to acknowledge the risks and hopes and of nuclear energy and answer the public’s fears about atomic power as a  force of destruction. With backing from the U.S. government, large (and costly) reactors were built in the 60s […]
