The Global Risks Perception Survey
(GRPS), discussed in the chapter
“Fractures, Fears and Failures”, is
the World Economic Forum’s source
of original data harnessing the
expertise of the Forum’s extensive
network of business, government,
civil society and thought leaders.
The survey was conducted from 28
August to 1 November 2017 among
the World Economic Forum’s
multistakeholder communities,
members of the Institute of Risk
Management and the professional
networks of our Advisory Board
Members.

Explanation
- Each month has two sets of 1-5, one set in shades of red for warmest/driest and one set in shades of blue for coldest/wettest.
- Ties are indicated by the same number appearing twice for the same month. Dr. David A. Robinson Jeffrey L. Hoffman, NJ State Geologist
- The period of record is January 1895 to December 2018. NJ State Climatologist New Jersey Geological & Water Survey
- Monthly rankings are based on State-wide averages of monthly temperature and precipitation. Rutgers University N.J. Dept. of Environmental Protection
- All data are from the web page of the New Jersey State Climatologist. http://climate.rutgers.edu/stateclim/ [email protected]
- NOAA altered the way it estimates monthly statewisde precipitation and temperature. All years were reanalyzed using this procedure resulting in minor changes from previously reported http://www.njgeology.org/

• The Earth reflects radiation not absorbed by the atmosphere & surface (lost heat).
• Strong greenhouse gases delay the exit of absorbed radiation back to the space
(enhancing atmosphere & surface temperatures).

Summing up:
Climate continues changing, locally and globally.
This includes changes in extremes.
Change will continue and likely accelerate in the
foreseeable future. Expect more extremes.
Impacts will expand, becoming increasingly noteworthy.
While ongoing change is certain, time remains for
mitigative and adaptive actions to address and
attenuate conditions.
