Just a slight comment on a statement in the second paragraph. It is the atmospheric perturbation of the CO2 concentration that has a long lifetime. The lifetime of a particular CO2 molecule in the atmosphere is only 4-5 years or so, being taken up by the active terrestrial biosphere or upper wind-mixed layer of the ocean. There are many examples of confusion about this and I personally think we ought to be a bit more precise in making this clear.
Yes, you're correct. Nevertheless, the essential point he's making is correct. If we increase CO2 in the atmosphere, it will be a long time before CO2 has returned to the pre-perturbation value.
I think it is more important to work towards reversing global warming; trying to adjust is like trying to adapt to a moving target. WE MUST FOCUS ON SOLUTIONS.
The main causes of climate destabilization and global warming induced vicious cycles are the high greenhouse gas levels - they are partly high due to the loss of vegetation - about `1/5 since 1850, largely due to beef production, today utilizing 75-80% of all arable land. If beef production would be decimated and much of this land would be reforested, returned to a natural state of high prairies and wet lands, most excess CO2 would be removed from the atmosphere. In addition, we can plant bamboo, other rapidly growing plants like algae; and there are some 9 million km2 of land that is not used by humans, which could be reforested with over a trillion trees. (The lush vegetation would immediately improve the local climate.) For long-term sequestration of carbon, we also can prevent much of the decomposing of dead plant material and other organic matters, keeping it dry and/or cold (in heaps protected with roofs), by sinking wood into deep lakes or cold oceans, immersing organic material in stagnant water, covered with plants (such as duck weed in warm, peat moss in cool areas). Just burying dead wood, covered with clay, greatly slows decomposition.
However, we need comprehensive emergency government actions, which will not happen unless NGOs, activists and informed people demand it. Not working towards these goals is cruel, maybe genocidal - the poor cannot adapt to the rapidly worsening weather catastrophes.
Please help us educate the people regarding solutions - grassroots movements must coalesce to form a mass movement that demands a radical, effective government response - we must lead, other countries will almost certainly follow.
Good description of a theory of the potential influence of CC on rainfall intensity during storms. But what are the quantitative magnitudes of the CC-related components relative to the numerous other in-situ factors also influencing rainfall intensity? Historical data from the Texas Hill Country flash floods indicates that if CC affected the rainfall intensity, its magnitude was too small to be evident above the noise. The DOE report also indicates the CC-related components are insufficient to appreciably impact storm frequency or intensity.
Should we not emphasize the need for adaptation to the effects of CO2 accumulation that has already occurred. not just to the accumulation in the future that will be affected by policy?
Yes, we 100% need to adapt to climate change that has already occurred and that which we cannot avoid. And we should work hard to avoid the climate change that we is avoidable.
