You ( Andy Revkin) say
"Pursuing wise policies on curbing greenhouse gas emissions and on boosting resilience to extreme events both make sense,"
This is not true.It is now likely that for the next 30 years at least the earth will be in a cooling trend. Anthropogenic CO2 emissions have a hardly measurable effect on global climate compared with natural variability. Check my various posts on
climatesense-norpag.blogspot.com to see the empirical basis for this viewpoint.
The IPCC now says
"“Uncertainty in the sign of projected changes in climate extremes over the coming two to three decades is relatively large because climate change signals are expected to be relatively small compared to natural climate variability”.
Unless we get the science right we will make the wrong decisions.Cooling would bring e.g.more east coast hurricanes with some accompanying blizzards,more violent and frequent tornadoes and corn belt droughts and western forest fires . Warming e.g would bring more equable weather with better crop yields but with more category 4 Gulf Coast hurricanes.
We must identify the threats from either cooling or warming correctly and make the necessary infrastructue investments based on empirical cost - benefit analysis.
Even if the climate were to warm, curbing CO2 would make little difference at enormous economic cost - especially to the worlds poor , especially if ethanol and biofuel use continue to be mandated.
Adaptation is the only sensible policy in either case .
