A few key insights from Chapter 1:

• Why do all discussions about climate change involve greenhouse gases in particular? Those gases act like greenhouses, and have the ability to capture heat and maintain it for long periods of time. The more of those gases we release into the atmosphere, the more heat they trap inside it.
• Those gases won’t leave our atmosphere for tens of thousands of years, so their effects have been stacking for the past millennia. Before industrialization, those gases did not constitute a significant threat, but after it, their emissions grew exponentially at alarming rates.
• Fossil fuels are the energy sources like natural gas, oil, and coal that are formed by the compression of carbon underground. Burning them up for energy releases these carbons into the atmosphere. Carbon is a greenhouse gas, so it traps heat. Other greenhouse gases are methane and nitrous oxide.
• The goal for humanity is to achieve near-net zero greenhouse gas emissions. The ideal scenario would be to reach actual net zero, and then work on the net negative, as in trying to reduce the leftover greenhouse gases.
