Defining dangerous anthropogenic interference

Defining dangerous anthropogenic interference.

Dangerous Anthropogenic Interference The United Nations Framework Convention on Climate Change (UNFCCC) commits signatory nations (which includes all major nations including the United States) to stabilizing greenhouse gas concentrations at levels short of DAI. To properly define DAI, one must take into account issues that are not only scientific, but, as I have argued elsewhere (2), economic, ...

Avoiding Dangerous Anthropogenic Interference with the Climate System

The UN Framework Convention on Climate Change calls for the avoidance of “dangerous anthropogenic interference with the climate system”. Among the many plausible choices, dangerous interference with the climate system may be interpreted as anthropogenic radiative forcing causing distinct and widespread climate change impacts such as a widespread demise of coral reefs or a disintegration of the ...

On avoiding dangerous anthropogenic interference with the climate system: formidable challenges ahead.

The observed increase in the concentration of greenhouse gases (GHGs) since the preindustrial era has most likely committed the world to a warming of 2.4 degrees C (1.4 degrees C to 4.3 degrees C) above the preindustrial surface temperatures. The committed warming is inferred from the most recent Intergovernmental Panel on Climate Change (IPCC) estimates of the greenhouse forcing and climate se...

Dangerous human-made interference with climate: a GISS modelE study

We investigate the issue of “dangerous humanmade interference with climate” using simulations with GISS modelE driven by measured or estimated forcings for 1880– 2003 and extended to 2100 for IPCC greenhouse gas scenarios as well as the “alternative” scenario of Hansen and Sato (2004). Identification of “dangerous” effects is partly subjective, but we find evidence that added global warming of ...
