evidence: June 23 marks 30 years since United Nations Foundation Vice Chair and former Senator Timothy E. Wirth convened a historic hearing of the Committee on Energy and Natural Resources to discuss the issues of global warming and the greenhouse effect. At this hearing in 1988, policymakers were alerted to the irrefutable connection between man-made global warming and the impacts on our climate, and urged cutting greenhouse gas emissions and working to manage and mitigate their impacts. In the three decades since, multiple major United Nations climate bodies have been established, including the Intergovernmental Panel on Climate Change (IPCC) in 1988 and the UN Framework Convention on Climate Change at the Rio Earth Summit in 1992. [...] We have only just begun to meaningfully address many of the questions posed in that 1988 hearing, and the next 30 years must see dramatic and impactful steps to meet our climate challenge head-on. There’s simply no time to waste.
