However, this in itself is not enough to define what level of warming is «dangerous,» especially since the projections of actual impacts for any level of warming are highly uncertain, and depend on further factors such as how quickly these levels are reached (so how long ecosystems and society have had to respond), and what other changes are associated with them (eg: carbon dioxide concentration, since this affects plant photosynthesis and water use efficiency, and ocean acidification).

Scientists have devoted considerable effort to understanding what magnitude of emissions reductions are necessary to limit warming to this level, as the world faces increasingly dangerous climate change impacts with every degree of warming (see Box 1).

In addition, some scientists, including former NASA scientist James Hansen who is now at Columbia University, believe that atmospheric concentrations are already too high and that atmospheric concentrations of ghg should actually be lowered from their current levels of approximately 400 ppm CO2 to 350 ppm CO2 to prevent dangerous climate impacts.

These growing climate impacts, many more rapid than anticipated and occurring while global warming is less than 1 °C, imply that society should reassess what constitutes a «dangerous level» of global warming.

It will also confirm the accelerated rate of change for impacts such as sea - level rise, the steady retreat of Arctic sea ice and quickened melting of ice sheets and glaciers, as well as offer more detail on scenarios that will shape international negotiations over both short - term and long - term greenhouse gas emissions, including how long «business as usual» can be sustained without dangerous risk.
