6. Much of Global Warming is Irreversible and Will Continue for Centuries. In the most somber part of the report, the IPCC provides a truly geological perspective on the changes that we are causing. It notes that much of what we are doing to the planet is “irreversible on a multi-century to millennial time scale” and that temperatures will remain “at elevated levels for many centuries,” even if we completely stop emitting carbon dioxide. Indeed, the report states, much of the carbon dioxide that we’ve emitted “will remain in the atmosphere longer than 1,000 years.”
