2012 SkS Weekly Digest #31

SkS Highlights

Watts' New Paper - Analysis and Critique by Dana and Kenvin C created a stir amongst SkS readers and generated the largest number of comments of the articles posted during the past week.  Given that the Watts' paper was just a rough first draft, it is quite likely that the conversation will continue as the draft is revised and reposted.

Quote of the Week

"When I testified before the Senate in the hot summer of 1988, I warned of the kind of future that climate change would bring to us and our planet. I painted a grim picture of the consequences of steadily increasing temperatures, driven by mankind’s use of fossil fuels.

"But I have a confession to make: I was too optimistic.

"My projections about increasing global temperature have been proved true. But I failed to fully explore how quickly that average rise would drive an increase in extreme weather." - James Hansen

Scientific Term of the Week

Global Warming Potential (GWP) An index, based upon radiative properties of well-mixed greenhouse gases, measuring the radiative forcing of a unit mass of a given well-mixed greenhouse gas in the present-day atmosphere integrated over a chosen time horizon, relative to that of carbon dioxide. The GWP represents the combined effect of the differing times these gases remain in the atmosphere and their relative effectiveness in absorbing outgoing thermal infrared radiation. The Kyoto Protocol is based on GWPs from pulse emissions over a 100-year time frame.
