GIOAS co-organized with Para Limes a webinar, Removing Barriers to Buy Time from 15th to 17th February 2021, by invitation. Sir Martin Rees, Astronomer Royal and leading physicist delivered the opening Keynote of “Climate Change and Emerging Threats” for the webinar. Extensive discussions between the main participants led to the insight that a successful execution of action plans depends on the success with which five strongly interrelated stumbling blocks in the process are recognized and dealt with: finance, talent, vested interests, bureaucracy, and political will. The outcome of this webinar, is the book "Buying Time for Climate Action", the combined narrative of world-class experts, all committed to helping humanity survive its largely self-induced destructive course. Changing that course requires urgent action. Determining which actions will lead to helpful change requires insights into the stumbling blocks that always emerge when actions aimed at change are planned, resulting in lost time. The experts who contributed to this volume, through their expertise, networks, wisdom, and creativity, have largely concluded that the way to cope with the stumbling blocks is to avoid them by focusing on grassroots initiatives.
