global heat record of 2014 — please note the above graph is in Fahrenheit, not Celsius) can lead to such an extreme carbon feedback response, we know we can expect a lot more feedback - induced CO2 now that world leaders are about to seal a 3.5 degrees warming deal — if at least 2030 pledges are not raised before the start of COP21, the Paris climate summit.

Until then, count me among the skeptics who consider this a political rather than scientific issue, especially in light
of the fact that it is believed that the Antarctic and arctic shelves are breaking from stress (from «overgrowth»), not due to
heat, since they are larger than they have been during
recorded history, and that when the alarmists are proven conclusively to be wrong, they change the terminology («
global cooling» to «
global warming» to «
global climate change» - face it, the
global climate always has been and always will be very dynamic).
