The announcement by the U.S. and China was important for several reasons: Together they account for around 40 percent of global GHG emissions, according to the Union of Concerned Scientists; there had heretofore been few signs of a Chinese willingness to commit to capping emissions; and it raised hope that future global negotiations might actually yield an agreement to rein in emissions enough to keep the average global temperature from rising more than 2 degrees Celsius.

We'd driving the models with the GHG concentrations, and using carbon cycle models within the climate models to simulate the natural carbon fluxes (atmosphere - land and atmosphere - ocean), which themselves are affected by the simulated climate change, and the residual needed to balance the carbon budget then indicates the anthropogenic emissions that would give the prescribed scenario of CO2 rise.

Not necessarily because the real GDP per capita of Los Angeles is twice that of Berlin ($ US 21,432)- rather because the urbanization patterns in cities from high - income nations as Stockholm, Tokyo, and Berlin (with lower levels of GHG emissions) suggest that there is not necessarily an inevitable relationship between rising incomes, increasing use of private cars and increasing GHG emissions.

AGW is a hypothesis that makes sense, namely: — GHGs absorb outgoing radiation, thereby contributing to warming (GH theory)-- CO2 is a GHG (as is water vapor plus some minor GHGs)-- CO2 concentrations have risen (mostly since measurements started in Mauna Loa in 1959)-- global temperature has risen since 1850 (in ~ 30 - year warming cycles with ~ 30 - year cycles of slight cooling in between)-- humans emit CO2 and other GHGs — ergo, human GHG emissions have very likely been a major contributor to higher GHG concentrations, very likely contributing to the observed warming

Do you agree that a nation that refuses to reduce its ghg emission to its fair share of safe global ghg emissions on the basis of cost to it is implicitly taking a position on how high atmospheric concentrations of ghgs should be allowed to rise and that the higher atmosphere ghg concentrations rise the more people and the ecological systems on which life depends will be harmed?.

If you concede that climate skeptics have not proven in peer - reviewed journals that human - induced warming is not a very serious threat to human health and ecological systems, given that human - induced warming could create catastrophic warming the longer the human community waits to respond to reduce the threat of climate change and the more difficult it will be to prevent dangerous warming, do you agree that those nations most responsible for rising atmospheric ghg concentrations have a duty to demonstrate that their ghg emissions are safe?

For instance the following illustration prepared by EcoEquity and the Stockholm Environment Institute shows that the US fair share of global emissions, making what the authors of the report claim are moderate assumptions of what equity requires, demonstrates that equity not only requires the US to reduce its emissions to zero quickly almost immediately but that US obligations to prevent a 2 degree C rise requires the US to substantially fund ghg emissions reductions in other countries by 2025 despite achieving zero emissions by 2020.

If you concede that climate skeptics have not proven in peer - reviewed journals that human - induced warming is not a very serious threat to human health and ecological systems, given that human - induced warming could create catastrophic warming the longer the human community waits to respond to reduce the threat of climate change and the more difficult it will be to prevent dangerous warming, do you agree that those responsible for rising atmospheric ghg concentrations have a duty to demonstrate that their ghg emissions are safe?

Are you aware that the claim frequently made by opponents of US and other national action on climate change that if the country acts to reduce its ghg emissions and China or other developing country does not act it will make no difference because climate change will still happen is not true because ghg emissions from nations exceeding their fair share of safe global emissions are responsible for rising atmospheric concentrations of ghgs?

Do you agree that a nation that refuses to reduce its ghg emission to its fair share of safe global ghg emissions on the basis of cost to it is implicitly taking a position on how high atmospheric concentrations of ghgs should be allowed to rise and that the higher atmosphere ghg concentrations rise the more people and the ecological systems will be harmed?.

The rise in atmospheric CO2 levels is, of course, not only attributable to the US ghg emissions, yet the United States has played a major blocking role in preventing international action on climate change up until the recent more constructive role of the Obama administration which recently made commitments before the December Paris meeting to reduce US CO2 emissions by 26 % to 28 % by 2025 below 2005 levels.

If, for instance, the United States and India are required to reduce ghg emissions by the same percentage amount, for instance 90 %, then the US per capita emissions of approximately 20 tons CO2 per capita would allow US citizens to emit CO2 at the rate of 2 tons per capita while the current India per capita emissions of approximately 1.8 tons per capita would mean that the Indian citizens could emit only at the rate 0.18 tons per capita even though India needs to dramatically increase its energy use to assure that hundreds of millions of people economically rise out of grinding poverty and India has comparatively done little to cause the existing problem.

They include: (1) a 35 year US delay on climate action has made the problem extraordinarily challenging to solve, (2) US greenhouse gas (ghg) emissions are more than any country responsible for rise in atmospheric concentrations to present dangerous levels, (3) US ghg emissions not only threaten the US with climate disruption but endanger many of the poorest people around the world, (4) the Obama administration's pledge to reduce ghg emissions is far short of the US fair share of safe global emissions.

If you argue that high costs to a nation of reducing its ghg emissions to its fair share of safe global ghg emissions justify non-action, how have you considered the increased harms and risks to poor vulnerable people and nations that will continue to grow as atmospheric ghg concentrations continue to rise?

This is factually not true because as long as a developed nation's ghg emissions are above its fair share of safe global emissions they are contributing to rising atmospheric concentrations of ghgs.
