I have just returned from my engagement at the National Press Club, sponsored by the Marshall Institute Roundtable.

The talk was recorded, it should be available online in a few days.
UPDATE:  video now available [here]
The pdf for my talk is here marshall.   Much of the material from my talk comes from my recent congressional testimony:

UPDATE:  comments on McKitrick’s paper
With 39 explanations and counting, and some climate scientists now arguing that it might last yet another decade, the IPCC has sidelined itself in irrelevance until it has something serious to say about the pause and has reflected on whether its alarmism is justified, given its reliance on computer models that predicted temperature rises that have not occurred. – Rupert Darwall

I hope this will lead to a broader discussion about the contribution of natural variability to local climate trends and to the statistics of extreme events. - John Michael Wallace

Pick one:
a)  Warming since 1950 is predominantly (more than 50%)  caused by humans.
b)  Warming since 1950 is predominantly caused by natural processes.

Rapid warming in the last three decades of the 20th century, they found, was roughly half due to global warming and half to the natural Atlantic Ocean cycle that kept more heat near the surface. When observations show the ocean cycle flipped, the current began to draw heat deeper into the ocean, working to counteract human-driven warming. – Chen and Tung
An important new paper has been published in Science, by Chen and Tung.

Record breaking trade winds may have led to hiatus in global surface average temperatures.
A relevant paper was published in Nature Climate Change last week, that is creating some buzz:
Recent Walker circulation strengthening and Pacific cooling amplified by Atlantic warming
