SkS Highlights

John Mason's  A Rough Guide to the Jet Stream: what it is, how it works and how it is responding to enhanced Arctic warming has drawn rave reviews from scientists and non-scientists alike. If you have not already done so, you will want to peruse it and see for yourself.

In Has the rate of surface warming changed? 16 years revisited, Kevin C delves further into the the measurement and attribution of short term trends in surface atmospheric temperatures and concludes that his previously produced video does not sufficiently take into account all of the the causal factors, including El Niño, solar irradiance, volcanic eruptions, observational biases, changes in ocean circulation and possible long term oscillations. He is therefore withdrawing the video and will produce a new one in the future. 

Dana's Matt Ridley's misguided climate change policy is the tenth article that SkS has posted over the years in response to erroneous statements made by this prolific member of the UK's denier cabal.

Toon of the Week

H/T to Joe Romm's Climate Progress. 

Quote of the Week

Global warming is manifested in a number of ways, and there is a continuing radiative imbalance at the top of atmosphere. The current hiatus in surface warming is temporary, and global warming has not gone away.

Global warming is here to stay, whichever way you look at it by Kevin Trenberth, The Conversation, May 23, 2013

Report of the Week

The Bonn Declaration on Global Water Security

The water community assembled in Bonn for the Global Water System Project Conference Water in the Anthropocene to make a set of core recommendations to institutions and individuals focused on science, governance, management and decision-making relevant to water resources on Earth.

The declaration was issued by the Lord Mayor of Bonn during the closing ceremony of the conference (May 24) and was signed by the participants.

SkS in the News

Media coverage of The Consensus Project continued to pile up, into the hundreds of articles.

John Mason's A Rough Guide to the Jet Stream: what it is, how it works and how it is responding to enhanced Arctic warming has also drawn rave reviews from climate scientists.

SkS Spotlights

Coursera.org is offering a new online course which might be of interest to Skeptical Science readers:

Climate Literacy: Navigating Climate Change Conversations

Dr. Sarah Burch and Dr. Sara Harris from the University of British Columbia are taking turns delivering the video lectures and this is the course description:

Climate Literacy tackles the scientific and socio-political dimensions of climate change. This course introduces the basics of the climate system, models and predictions, human and natural impacts, mitigative and adaptive responses, and the evolution of climate policy.

To watch an introductory video and read more about this 10 weeks long course go to http://www.coursera.org/course/climateliteracy

Even though the course officially started on May 20, it is not yet too late to sign-up and getting up to date with the video lectures shouldn’t be a problem.
