Are you the next great climate scientist? Awarding $10,000 for the proven reproducible rate of CO2 forcing. (Verified by the UN IPCC)
Atmosphere Questions
These are all the questions I found related to this topic in the 3000+ pages of IPCC AR4 and AR5.
AR6 coming soon!
The IPCC distinguishes between clouds and water vapor as water vapor has the strongest influence on the natural greenhouse effect.
They go on to note water vapor is caused by air temperature not greenhouse gases so “scientists consider it a feedback agent rather than a forcing to climate change”. (AR5 FAQ 8.1 Page 666)
The IPCC notes there are different accounting methods used to compare CO2’s greenhouse gas effect to that of water vapor that adds to the natural greenhouse effect. Today they state water vapor is “approximately two to three times greater” in strength. (AR5 FAQ 8.1 Page 666).
Then there are questions on whether there has been an increase in water vapor in the upper troposphere as satellites show the “globally averaged upper tropospheric relative humidity has changed little over the period 1979–2010 while the troposphere has warmed”. (AR5 Section 2.5.5.3 Page 207)
Last, here in AR5 the IPCC notes clouds are hard to model but believe with “very high confidence” differences are caused by modelled climate sensitivity. (AR5 Chapter 9 Executive Summary Page 743)
Despite these basic questions the IPCC states water vapor feedback is “extremely likely positive”. When it comes to clouds, they are “less certain but likely positive” feedback. (AR5 Chapter 7 Executive Summary Page 574)
So Many Atmosphere Questions.
The next section covers a very interesting and important question in AR5 that we could be hearing much more of in AR6 is if CO2 is the “control knob on climate” for water vapor the most important greenhouse effect by far.
The Questions Chapter
Over 150 climate questions from AR4/AR5.
Questions and more questions.
This section highlights all the important climate questions described in the UN’s IPCC assessment reports, AR4 and AR5. AR6 is coming soon!
AR4 and AR5 make up the most complete and current climate information out there, a road map for future generations. However, they are not the easiest reads because information on any particular subject is found throughout the 3000+ pages of these reports.
You make think over time there would be less questions as the climate gets figured out, but from AR4 to AR5 the number of question and material increased by several fold.
One reason for this increase in climate questions from AR4 to AR5 is the fact many predictions made in AR4 were missed, and things have been learned.
The IPCC examines most of these in more detail throughout AR5 using AR4 as a base for the science.

What is the IPCC?
UN’s IPCC Assessment Reports 4 and 5 (AR4 2007 and AR5 2014). These UN reports include over 600 authors from 32 different countries assessing 9,200 peer-reviewed studies so they are the all-inclusive on the current state of climate science putting out new reports every seven or so years.
AR5 explains the United Nation’s IPCC was created in 1988 to provide world governments with “clear information on the state of today’s climate science as well as potential impacts, and options for adaptation and migration based on regular assessments”. (AR5 Section 1.2.1 page 123)
