Are the hurricanes in 2017 and the damage and fear and imagery having a significant impact on moving public sentiment regarding climate change among those who still at this late date resist the truth? Your opinions?

I would say that, despite the hurricanes, we are willfully unaware of how our choices affect the climate system. People don't want to connect it to their lifestyles. They experience a kind of cognitive dissonance where they know that climate change is caused by using lots of fossil fuels, but they feel that they are very important and they need that four wheel drive or that flight to the Caribbean because they have some extra money laying around. I have some friends who consider themselves to be environmentalists who flew up to see the polar bears because they might not be around much longer...

The first step is to recognize the problem and then the 2nd step is to recognize how ones lifestyle aggravates or helps to contain the problem. Some folks don't want to open the door to the first step already knowing that they won't have the integrity to deal with step 2.

And yet many have children and are invested in their well being.

I think naming this cognitive dissonance in a nice sterile and hygienic way of saying pathologically narcissistic. A mother addicted to crystal meth will allow her children to starve in the next room. Some hopelessness and addiction is part of the problem as well. And fear. For some it is refusing to participate in anything that requires sacrifice toward society at large as if this is an unpatriotic "socialist" sentiment. There are lots of rationalizations one can latch on to for not wanting to even consider step 1.

It's interesting though that those folks affected by the hurricanes and living in areas where they have directly suffered the consequences do increasingly recognize climate change regardless of party or ideology.

As long as one can compartmentalize the issue as a problem others some where else are suffering, even if it is your own race and nation, as long as it is not affecting you directly, then you can stay hermetically sealed in denial.

All of this seems to be born out with the experience to date with these most recent storms. And yet at the same time there is always this critical mass that is reached when then a population will acquiesce to the truth.

Are we close to this point?

I doubt it. There was much hullabaloo after first Katrina and then Sandy, but we adjusted and a new TV season started.

No, IMHO......NOPE!

I agree. I don't know if we'll ever get to the point where we recognize what's going on. Humans have a vast capacity for self delusion. Our Dear Leader pulled us out of the Paris Climate Accords, and the hurricanes started up. Instant Karma!

Revi - "willfully unaware". An excellent phrase that covers far more then the climate situation.

And ibon: there's the problem that Cog eludes to: the citizens of the US have suffered as much or worse from hurricanes during the first half of the 1900's (when AGW would probably have had minimal to no impact) then we've suffered in the last 20 years. Which isn't proof that AGW isn't making the situation worse to some degree. But pointing to the severity of recent hurricanes as proof is not greatly different the deniers of global warming using unusually cold snaps as "proof" that global warming isn't happening.

As I pointed out elsewhere: the Labor Day Hurricane of 1935 had a track almost identical of that of Irma. One hurricane historian estimated that the 1935 storm happening today would cause damages on the order of $1 TRILLION. And many thousands of deaths compared to the 450 killed in the 30's when much fewer folks lived in western FL.

Cog,
Gravity is one thing.
Wind is something else.
But when shooting at a couple of hundred yards they combine to significantly affect the flight path of a bullet.

That said, IMHO, we have always had hurricanes and are idiots for being surprised by them. The large dollar impacts are because we have about zero planning capacity to see the obvious. CC has little to do with the strength of the hurricanes. Little, not zero.

Over the fullness of time that will change.

And we have zero planning capacity to deal with it.

Don't you think your own comments and attitudes support that assertion?

How about this plan? Don't live next to the coast and if you do, build your structures to withstand high wind events and design your drainage to deal with flooding. Just a thought off the top of my head. But I recognize my thinking might be flawed since I'm not a not a high speed climatologist like everyone else is here.

Cog,

Your just trying too hard to be critical. Your logic breaks down and makes you sound, well irrational.

I don't think anyone here disagrees with your technical solution. In fact it has been suggested over and over. So why the sarcasm?

Paul B. on Capital and CC, superstorms.

https://www.youtube.com/watch?v=mlG6I9nlDgQ

I discuss how ongoing & cascading climate chaos is the root cause of our crisis in capitalism. The US is considered one of the richest & most powerful countries in the world, yet is being brought to its knees from repeated hits due to Superstorms made worse by climate change chaos.

It is not just climate change that threatens people. As technology rapidly advances, & more & more jobs are lost due to artificial intelligence & robotics, capitalism will be at risk of complete collapse. How do we address these growing risks & come out standing at the other side?

Just playing along here would you leave this up to the public to choose how they build or would you agree that municipalities can make building codes including where to allow structures based on statistical weather patterns and forecasted sea level rise? Remember also the private market's power here too regulate. For example, insurance companies can choose to discontinue offering wind insurance in coastal areas and to certain structures like wood framed homes or homes not built on stilts as you just mentioned.

rebuilding structures in flood plains?

I have always believed the private market, namely the banks and insurance companies will lead the way toward society adapting to climate change. This will happen from pure financial calculus, without having to ever even have a climate change debate won or lost!

What this means is that we won't be having this big national political debate around mitigation of climate change. We will simply cope with the consequences and this will be lead by economic considerations. Consumption goes down when the costs force per capita consumption downwards. When a bank obligates you to have wind insurance too buy a home and the insurance companies triple the current rates then this economic burden will collapse coastal property prices without ever having had a political debate .

We are powerless to move beyond market considerations. Because higher values like protecting the environment or protecting the health of citizens will always take the back seat to economic growth for the vast majority of Kudzu Apes.

It is through the consequences, the catalyst of consequences, that human societies will adapt to climate change.

There will be small populations who will consider the moral and environmental implications of their choices and will make lifestyle choices based on this. This segment of the population might grow. But that was not what I was addressing when I posed the question.

Apologies: I should have researched the El Niño dynamic sooner. I recall years ago when the strength of the El Niño in the Pacific appeared to greatly affect the level of Hurricane development. Today there appears to be a broad consensus by meteorologists that the El Niño dynamic controls the hurricane dynamic. A predicted weak El Niño (lower Pacific sea temperatures) did forecast a strong 2017 hurric season. And while warmer Carribean waters added to the severity El Niño was still the dominant factor. A strong El Niño would have produced strong high pressure waves that would have tended to deflect hurricanes away from the US mainland. Additional strong high level winds would have inhibited the growth of the storms. And don't hang it all on this one reference: search "El Niño and hurricanes" and you'll find many other supporting studies:

So let's hit the relationship between ocean warming and the activity level of the 2017 Atlantic hurricane season. The professional meteorologists use their models of the development of the El Niño to predict hurricanes. Here's an example of such a prediction at the beginning of the 2017 season.

https://m.accuweather.com/en/weather-ne ... s/70002059

"An expected delay in the onset of El Niño may increase the number of tropical storms and hurricanes to form in the Atlantic during 2017. El Niño is part of a routine fluctuation in sea surface temperatures over the tropical Pacific. When these waters enter a warm phase of a few degrees Fahrenheit or greater compared to average for several consecutive months, the pattern is designated as El Niño. When El Niño occurs, it typically creates strong winds from the west at mid-levels of the atmosphere. These winds tend to prevent formation, limit strengthening and can lead to an early demise of tropical storms."

So to be clear: the LACK of warming of the surface temperatures produce a WEAKER El Niño effect which allows more and stronger Atlantic hurricanes. And so far that prediction from last spring appears to be spot on. Or more simply: warmer then average Pacific waters reduce the severity of hurricanes.

People will believe what they want to believe, as for science its clear the evidence is not there (excepting for those clairvoyants who already know the truth) see statement from WMO:

There is no clear evidence that climate change is making the occurrence of slowly moving land-falling hurricanes in the Houston region, such as Hurricane Harvey, more or less likely. However, some aspects or "ingredients" of the Harvey event may have linkages to climate change.

.... a detectable (i.e. outside the range of natural variability) anthropogenic influence on hurricane rainfall rates has not yet been convincingly documented in observed data.

Model simulations also indicate that hurricanes in a warmer climate are likely to become more intense,....Such changes are not yet clearly detectable in observed data due in part to limitations of existing datasets.

Ongoing sea-level rise, attributable in part to anthropogenic climate change, also exacerbates storm surge for land-falling hurricanes such as Harvey. Damage resulting from the geophysical event itself will be influenced by the vulnerability of the affected region, which is increased by factors such as population and infrastructure growth, and potentially decreased by mitigation measures such as flood control systems. Extensive coastal development has generally led to large increases in hurricane damage in U.S. coastal communities over the past century.

Jaw - And as I've posted the scientific consensus is that El Niño has the strongest influence on our hurricane seasons. And that cooler then average Pacific waters = weaker El Niño = stronger hurricanes. So a denier might argue this as proof that AGW is NOT making hurricanes more destructive. But here's the problem with that "logic": those cooler waters do not appear to be a function of atmospheric temps but circulation patterns in the Pacific. Search "El Niño Pacific circulation". Obviously that dynamic has been going on much longer then being caused by AGW. But that isn't to say AGW might not be affecting the dynamic to some degree. But I suspect the system is too complex with a number of uncertain variables to prove it.

Same problem proving the negative effects of AGW: cherry picking certain phenomenon to support it allows deniers to do the same. Such as the 1935 Labor Day hurricane that could have easily caused many times the devastation in FL that Irma did. Or the 1900 Galveston hurricane that killed many more in the US then any other storm in history. In both events AGW could not have been a great factor if at all. Those events no more prove the insignificance of AGW then Harvey and Irma prove the validity of that point. Sorry but the anecdotal knife cuts both ways.

It should require a full global system wide analysis. Which is probably too complex to do.

minus WMO, of course. Consensus minus WMO. No consensus. False statement.

    consensus: noun
    general agreement.
    "a consensus of opinion among judges"

Rockman, AGW is a theory, it makes sense to most people. As with any theory the proponents of the theory are the ones required to prove the theory. I have no problem believing in AGW or in a natural warming cycle, but I have a big problem with people who use every weather event to say aha, see here's proof of AGW and usually follow with it's also Catastrophic, the worst ever, hence we must do something to save the planet. When in reality there is no clear evidence yet of an AGW effect (again see statement from WMO scientists), which leaves us with belief and belief is not evidence. As you have pointed out hurricanes have cycles, same for weather and climate and many cycles are beyond our long term memory and/or lifespan, making current weather events seem the worst ever, when mostly they are not. 100 years from now we will have a much better scientific database to draw from and I expect people then will look back on today and laugh at the hysteria AGW provoked (Y2K anyone?). Forecast for below freezing temperatures tonight, happily I can still use natural gas to heat my home.
