		<description><![CDATA[&#8220;A picture is worth a thousand words&#8221;, says the popular adage. It is something that we, as climate scientists, should take seriously, especially given the vast quantities of literature we might read through.

		<description><![CDATA[There has been some recent blog discussion on comparing observations and climate models consistently. Here is my effort at such a comparison using the CMIP5 models which are already available. Estimating &#8220;global temperature&#8221; from observations raises lots of subtle issues &#8230; <a href="http://www.climate-lab-book.ac.uk/2012/on-comparing-models-and-observations/">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>

		<description><![CDATA[Reliable estimates of uncertainty are arguably more important than the actual value being quoted. I recently came across a classic example in astronomy. From the late 1920s, estimates have been published for the &#8216;Hubble Constant&#8217; &#8211; a measure of how &#8230; <a href="http://www.climate-lab-book.ac.uk/2012/reliable-uncertainty/">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>

However, there is also considerable uncertainty in the model simulated internal variability.
