Back around 1980, they had already forecast the CO2 emissions curve we are on (we are tracking their best guess scenario) and the economic impact. We’re currently approaching the regional disasters stage. They thought we’d hit 2.5C warming by either 2038 or 2025, which will be enough to halt global economic growth. We seem to be on the 2038 curve. That curve has us hitting 5C by 2069, with globally catastrophic impacts. The document I’m referring to is here: https://download.industrydocuments.ucsf.edu/g/f/f/l/gffl0228/gffl0228.pdf https://download.industrydocuments.ucsf.edu/g/f/f/l/gffl0228... It is a set of AQ-9 climate task force minutes. In the end, they conclude: —— AT A 3% PER ANNUM GROWTH RATE OF C02, A 2.5°C RISE BRINGS 2 WORLD ECONOMIC GROWTH TO A HALT IN ABOUT 2025. Even If this estimate is grossly wrong it Is still probable that • WHETHER THERE ARE GROUNDS FOR IMMEDIATE RESPONSE TO THE THREAT DEPENDS ON THE VALIDITY OF THE LONG MARKET PENETRATION TIME CONCEPT. • EVEN IF THE LATTER IS APPLICABLE, PRESENT DAY SIGNIFICANCE OF THE IMPACT DEPENDS STRONGLY ON CHOICE OF A FUTURE DISCOUNTING FACTOR. • NEED FOR IMMEDIATE POLICY ACTION HINGES ON THESE LAST TWO FEATURES. —- The document also says that back in 1980, there was no leeway to wait to take action to mitigate climate change. Instead, they ended up spending unprecedented amounts of money on disinformation campaigns and in support of climate change denying politicians in the 1990s and afterwards to prevent action from being taken. I guess their discount factor valued their grandchildren at ~ $0.
