This is certainly true of three major ethical dilemmas now complicating the climate change debate: how to balance the rights and responsibilities of the developed and developing world; how to evaluate geo - engineering schemes designed to reverse or slow climate change; and how to assess our responsibility to future generations who must live with a climate we are shaping today.

This method of «cloud brightening» was one of the geo - engineering schemes for intentionally intervening in climate to counteract global warming.

The BIG difference between hare - brained geo - engineering schemes, such as those you mentioned and burning fossil fuels to provide accessible low - cost energy and transportation to drive the world economy, is that the geo - engineering schemes are costly but DO NOT ADD INHERENT VALUE.

Those few that have been proposed (carbon capture and sequestration for all new coal - fired power plants, geo - engineering schemes, switch to renewables such as wind and solar, etc.) would be extremely costly, could result in unknown and unintended negative consequences and would not bring any significant reduction of theoretical greenhouse warming by 2100.

I mean, assuming there will be no global geo - engineering scheme that removes CO2 from the atmosphere on a massive scale, if I were to take the IPCC's middle - of - the - road ECS estimate of 3º Celsius per doubling of atmospheric CO2eq and combine it with a rather weak climate mitigation emissions scenario (e.g., RCP 6.5, which peaks around 850 CO2eq ppm)... we are talking about 120º Fahrenheit days being a common occurrence in the summers of Houston far into the future, right?
