2012 SkS Weekly Digest #31

Posted on 6 August 2012 by John Hartz

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.

SkS in the News

Dana and Kevin C's Watts' New Paper - Analysis and Critique was featured on Victor Venema's blog, Variable Variability.

SkS Spotlights

The Finnish Meteorological Institute's mission is to produce high-quality services and scientific know-how on the atmosphere and seas. The Institute uses its expertise to provide services that promote public safety and enhance well-being among people and in the environment, taking into account the needs to maintain preparedness.

The Finnish Meteorological Institute

  • observes the physical state, chemical composition and electromagnetic phenomena of the atmosphere
  • observes the physical state of the Baltic Sea and the Arctic sea areas.
  • operating on the 24/7 principle, produces high-quality information and services about the past, present and future states of the atmosphere and seas
  • conducts high-standard research and development in the fields of meteorology, maritime sciences, air quality, space physics and earth observation
  • carries out competitive commercial activities, based on expert services, both in Finland and abroad
  • plays an active role in national and international cooperation
  • actively disseminates information about matters associated with the atmosphere, seas and near space

  1. Close: they didn't *quiiite* get the ostrich correct. I submit a more accurate version... Our ostrich be *cooked*!

  2. Caveat: Without a general section I can't find a better spot to make general comments. From the comments policy: Comments using labels like 'alarmist' and 'denier' as derogatory terms are usually skating on thin ice. 'Denier' gets thrown around a fair bit. At what point is it derogatory as opposed to thin-ice skating?
