If governmental policies do not change, what is the likelihood that CO2 concentration in the atmosphere in the year 2050 will be at least double that of the pre-industrial era (1750)?
Will there be sufficient deployment of carbon capture and storage (CSS) technology by 2050 to have a significant impact on atmospheric CO2 levels?
What is the likelihood that global average sea level will rise more during this century than the highest level given in the 2013 assessment of the IPCC (.98m)?
What is the likelihood that global average sea level will rise less during this century than the lowest level given in the 2013 assessment of the IPCC (.28m)?
How strongly do you agree or disagree with the following statement made in the Wall Street Journal on September 14, 2013?
A key prediction (on equilibrium climate sensitivity) of the draft 2013 assessment of the IPCC “points to the very real possibility that, over the next several generations, the overall effect of climate change will be positive for humankind and the planet.”
Source: "Dialing Back the Alarm on Climate Change,” Matt Ridley, Wall Street Journal, Sept 14 2013.
Note: Equilibrium climate sensitivity (ECS) refers to the amount of warming that would be expected over the long term owing to a doubling of atmospheric carbon dioxide concentration relative to the pre-industrial era.
If you were the scientific advisor to a $100-billion venture capital fund with a 100-year time horizon and a goal of averting a dangerous level of global warming, which would you recommend as the top priority for investment?
Carbon capture and storage
Energy efficiency (including smart grids)
Next-generation nuclear power (Generation III and 3+)
Centralized renewables (geothermal, hydro, solar, wind, biomass)
Distributed renewables (geothermal, hydro, solar, wind, biomass)
Solar radiation management
None of the above can avert a dangerous level of global warming
None of the above is needed (no dangerous global warming is likely to occur this century)
