Cooling To Warming - History Of Climate Change Research

The video discusses the establishment of independent data sets in the 1980s that showed Earth was warming, despite earlier cooling trends. Early scientists predicted that significant warming signals would appear around 2000, which proved accurate. During the 1980s and 1990s, there was tension between scientists and policymakers, with the latter often dismissing climate change as speculative. The 1988 Toronto conference, held during an unusually hot summer, drew significant media attention, highlighting global warming as a major issue and urging policymakers to take action.
