These comments constitute a response to erroneous statements and misrepresentations made in a report published by the Met Office in July 2013: “The recent pause in global warming (3): What are the implications for projections of future warming?” (the Report).

Researchers need to communicate the policy implications of their results clearly and comprehensively to policy makers and the public—including a clear assessment of the uncertainties associated with their results—while avoiding advocacy based on their authority as researchers.

It looks like the Arctic sea ice is close to reaching its seasonal minimum, reflecting a substantial increase in sea ice relative to the record breaking minimum in 2012.

There is growing evidence to support the hypothesis that the pause cause is tied to a change in tropical Pacific Ocean circulations. What are the implications of this for climate sensitivity and attribution of warming in the latter part of the 20th century?

One of the catastrophes associated with anthropogenic global warming (CAGW) is a rising sea. Is the projected rise and rate unprecedented? Will it be catastrophic?

U.S. and European Union envoys are seeking more clarity from the United Nations on a slowdown in global warming that climate skeptics have cited as a reason not to “panic” about environmental changes, leaked documents show.

According to the IPCC, “climate variability refers to variations in the mean state and other statistics (such as standard deviations, the occurrence of extremes, etc.) of the climate on all spatial and temporal scales beyond that of individual weather events. Variability may be due to natural internal processes within the climate system (internal variability), or to variations in natural or anthropogenic external forcing (external variability).”

Update: New comment from Xie
My mind has been blown by a new paper just published in Nature.

Recent observed global warming is significantly less than that simulated by climate models. This difference might be explained by some combination of errors in external forcing, model response and internal climate variability.

Well, if you judge ‘sides’ by what climate scientists have to say about the science, it is getting difficult to tell.

Is the dramatic decline of Arctic sea ice, spurred by manmade global warming, making the weather where we live more extreme? Several recent studies have made this claim. But a new study finds little evidence to support the idea that the plummeting Arctic sea ice has meaningfully changed our weather patterns.

Motivated reasoning affects scientists as it does other groups in society, although it is often pretended that scientists somehow escape this predicament.
