Given that the Cancun agreement can also be understood to legitimize any national ghg emissions target that is proposed voluntarily, even if it is insufficient to achieve the 2 °C temperature limit goal adopted by the Accord, let alone the duty to try and
prevent any additional warming, the Cancun agreements can be seen as ethically problematic.
Given this, a strong ethical argument can be made that all nations have a duty to try to
prevent additional warming of almost any amount, while the Cancun agreements legitimize an additional 2 °C warming.
Every time the oceans get warm enough to melt polar ice it always snows enough to increase Albedo to
prevent additional warming above the upper bound set by this wonderful polar ice cycle that bounds the temperature of earth.

The United Nations Environment Program estimates that cutting back on methane and soot emissions alone could
prevent 0.7 degree Celsius of
additional warming by 2040 — and those cooling benefits could come faster than comparable cuts in CO2.
It will also include complicated models of interconnected ecosystem feedbacks.The panel's last report noted that preliminary knowledge of such feedbacks suggested that an
additional 100 billion to 500 billion tons of greenhouse gas emissions would have to be
prevented in the next century to avoid dangerous global
warming.

If the patient becomes colder than 98 degrees F,
additional warming measures can be taken to
prevent your dog or cat from becoming hypothermic.
Back in 2009, at the United Nations (UN) Framework Convention on Climate Change, nations around the world drew a hypothetical line in the sand, pledging to do everything in their power to
prevent the world annual average temperature from
warming an
additional two degrees Celsius (3.6 °F)- known as the Copenhagen Accord.
Although there is considerable scientific evidence that limiting
warming to 1.5 degrees C is necessary to
prevent very dangerous
warming, a fact implicit in the recent Paris Agreement in which nations agreed to work to keep
warming as close as possible from exceeding 1.5 degrees C
additional warming, if the international community seeks to limit
warming to 2 degrees C it must assure that global emissions do not exceed the number of tons of CO2 emissions that will raise atmospheric concentrations to levels that will cause
warming of 2 degrees C.
For instance, a recent paper by Jim Hansen and seven other authors concluded that
additional warming should be limited to 1 °C
warming to
prevent serious harms.
So, even if we were to
prevent any more ice from melting, the planet still has some
additional warming on the horizon.
