By Randy Showstack, Eos/AGU. For GSS Climate Change chapter 9. Excerpt: Several forthcoming reports by the Intergovernmental Panel on Climate Change examine what needs to be done to take control of our climate future. ...With a United Nations climate change conference scheduled for Bonn, Germany, from 6 to 17 November, two high-level reports released this week warn about the increasing risk of climate change. In addition, the Intergovernmental Panel on Climate Change (IPCC) is working on a separate report, to be issued in 2018, about the effects of global warming at 1.5°C above preindustrial levels. A 30 October report from the World Meteorological Organization warned that in 2016, globally averaged concentrations of carbon dioxide surged in 1 year from 400 to 403.3 parts per million, the highest level in 800,000 years. Also, a 31 October report from the United Nations (UN) sounds an alarm about the need for accelerated short-term actions and enhanced longer-term national ambitions to meet the Paris climate agreement goal of holding global warming to well below 2°C compared to preindustrial levels. ...In most countries, governments are addressing climate change in the context of other national priorities such as energy security and poverty alleviation, Lee said, adding that “improvements to climate policy programs need to engage these broader national priorities.” ...the UN report released yesterday questions whether a 1.5°C goal is possible. It notes that the gap between emissions reductions that are needed and national pledges, known as Nationally Determined Contributions (NDCs), on climate action “is alarmingly high.” It “is clear that if the emissions gap is not closed by 2030, it is extremely unlikely that the goal of holding global warming to well below 2.0° can still be reached,” the UN report states.... https://eos.org/articles/ipcc-chair-discusses-limiting-global-warming-to-1-5c
