The group of scientists recruited as authors and reviewers on this annual report is considerably broader than in previous years, both in numbers and geographically. Understanding global catastrophic risks is important. Without an intimate knowledge of these threats, we cannot even begin to work on models that can help us manage, reduce and, preferably, eliminate them more rapidly, effectively and equitably.
