chart clearly showed 1°C is the danger limit and 2C would be catastrophic to billions of people. James Hansen was largely referring to triggering planetary catastrophes at 2C from the irreversible destabilization of ice sheets and huge amounts of Arctic methane. The IPCC impacts chart does not show these. In fact Arctic methane leading to runaway global climate change was not included in the 2007 IPCC assessment and is not in the AR5. Anything above 1C, even according the highly conservative IPCC assessment, is a human population environmental health catastrophe of unimaginable proportion.</span> </span></span></span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">Note that health impacts from climate change start from today's degree of global warming. </span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Arial;">Note also crop losses to smallholders and subsistence farmers at today's warming.</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Arial;">The above in fact fits with an estimate by DARA that 400,000 people are being killed by global climate change per year. </span></div>

<span style="font-family: Arial, Helvetica, sans-serif;">These impacts are from climate change only. The assessment does not assess the combined end result impact of the many climate change stresses to population health. The assessment does not account for climate change impacting on top of ongoing health stresses and environmental degradations. The most climate vulnerable regions are where billions of the most socio-economically and nutritionally deprived live. They will suffer more end result population health damages and sooner than the climate change alone assessment finds, These billions have little health services that will collapse under small climate change impacts. </span></div>

<span style="font-family: Arial;">The IPCC impacts chart does not include the greatest of all dangers. These are the extreme irreversible catastrophic planetary transformations (or large scale singularities) such as multiple cascading Arctic global warming amplifying feedbacks. </span><span style="font-family: Arial;">The science calls these low probability extreme impact effects. As reliable data is not available to model the probabilities, this group of impacts is sidelined. </span></div>
