Reading the special report of the IPCC (2012) on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation and the more recent Climate Change 2014: Impacts, Adaptation, and Vulnerability (IPCC 2014), it is evident that remarkable progress in research has been made in integrating social vulnerability, natural hazards, and climate change.
A more recent and proximate meteorite impact occurred in 1992.
More recent studies suggest its impact is not significant, and small tortoiseshell declines have been linked to drought-stricken nettles.
