Effects/Implications of Climate Change on Jetstreams

Recommended Posts

How much responsibility should the U.S., Canada, China, UK etc take in absorbing the cost to relocate these people as they certainly won't have the funds? (there are many other islands that I have not included in this list)

None specifically. Aid would have to be handled the same way it is handled for earthquakes, large storms or famines. It goes without saying that a world which was not shy about using the cheapest fuel source available would be in a much better position to provide aid than a world which legislated itself into fuel poverty.

So the "Climate change might be awesome" dudes are offering sober political analysis....whereas the "it might not be awesome" dudes are sputtering "unjustified nonsense."

No, some people just think that a cost benefit analysis should be done to weight the benefits and costs of performing mitigation policies, rather than blindly advocate for severe mitigation policies without sufficient evidence.

The real question is what to do if we have no information? My position is all climate predictions (good and bad) are garbage and making decisions as if any are likely to be true is delusional. That is the rational position.

But we have information, and plenty of it...

Aside from the fact that there is scientific consensus on climate change, you don't even need to look at predictions.

Can you define this 'consensus' please? Because it appears to mean different things to different people.

What I said is there is no consensus that climate change has had any negative effects to date. If there is any consensus it is that there is no evidence that climate change is making extreme weather events like hurricanes or droughts more frequent or damaging.

Oh come on, this is not true.

Increases in global temperatures due to increases in CO2 concentrations have caused sea levels to rise by a few additional millimeters over the past few decades. This makes certain places along the ocean slightly more vulnerable to storm surges. That is a negative effect.

Reduction in polar-equatorial global temperature gradient will reduce the speed of jetstreams, which will increase the chance of resonance phenomena as I explained in the original post. One could make a good argument that the increase in frequency of resonance phenomena is a negative effect.

Hurricanes becoming more frequent or severe however is complete nonsense and the reverse is true due to the physics of heat engines and the fact that the temperature differential between the Earth's surface and the top of the troposphere will be reduced.

And of course there will be no hardships for these hundreds of thousands of people?

What is the alternative? Create hardships for billions by inflating the cost of energy and denying the poor access to the energy consuming conveniences that we take for granted? Your priorities are really twisted if you think the welfare of billions is less important than a few islands.

It would depend on what percentage of the habitability are primary succession, autogenic succession or allogenic succession. Regardless, the belief that this currently uninhabitable land would quickly become in any meaningful way habitable is pretty at odds with the mainstream thinking of scientific experts. As is the belief that these areas would become habitable at a time when the losses would consist of only Tuvulu and not current coastal areas throughout the world.

Indeed, how able certain land or plant-life is able to adapt to changing climate should be considered when evaluating what course of action should be taken. Thanks for bringing up this point.

It is also easy to imagine that humans will adapt easily without any major hardship to whatever changes may come.

I am responding to your comment above. Why you continue to insinuate that no major hardship will befall anyone is ludicrous.

Any effect is infinitesimally small and swamped by other factors. There is no way it is measurable today which means my original statement is true: there is no evidence of negative effects. When I say evidence - I mean something measurable - not a hypothetical problem that depends on a computer model. Edited by TimG

I can't imagine these islands that will vanish due to sea levels rising will adapt easily without any major hardship.

Kiribati (halfway between Hawaii and Australia) population, just over 100k

Maldives - population 325k

Seychelles - population just under 100k

Solomon Islands - population close to 600k

Micronesia - population close 100k

How much responsibility should the U.S., Canada, China, UK etc take in absorbing the cost to relocate these people as they certainly won't have the funds? (there are many other islands that I have not included in this list)

That is less than 1.3 million people. To put things in perspective, the population of the Earth is over 7 billion.

Does that mean they will suffer no hardship? That is the point I am making.

I never said they wouldn't. I disagree with Tim. See my above post.

When I say evidence - I mean something measurable - not a hypothetical problem that depends on a computer model.

There are plenty of negative effects and plenty of positive effects. I just gave you 2 such negative effects. The negative effects may be small, or may be offset by positive effects, but at least acknowledge their existence.

You said there would be no hardships and you were minimizing the real hardships of hundreds of thousands of people having to relocate. I take issue with that. I understand there is no turning back and these islands will become uninhabitable, but please do not diminish their hardships.

Before you start worrying yourself about those places, how about some alarm about the Florida Keys (as posted previously):

Kiribata - average elevation 20 feet

Micronesia - various scattered islands from sea level to as high as 791 meters

Seychelles - Highest point - 905 meters. Average elevation of it's most populous area (Victoria) is 200 feet.

Solomon Islands - average elevation is 160 feet

Florida Keys - 125 square miles with 80,000 people. Highest point - 18 feet. Average elevation is 3 to 4 feet.

Instead of listening to all the alarmism that's been spouted over the last 30 years, just keep your eyes on the Keys because if oceans are really rising out of control, the keys would seem to be the most exposed.

As I mentioned above, I left off plenty of other places that should be on that list.

Over the next 400 years billions of people will suffer numerous hardships from the vagaries of nature. The "hardship" that a million or so islanders may suffer is quite irrelevant by comparison. More people suffer from a despot running North Korea today than from SLR. Why should we care about SLR?

You are listing hypotheticals which I am not discussing or even disputing.

I am discussing real (a.k.a. measureable) effects that we can see today. There are none.

You are missing my point. You said "It is also easy to imagine that humans will adapt easily without any major hardship to whatever changes may come."

How can you possibly think that hundreds of thousands of people having to relocate will not suffer major hardship?

They can be relocated if necessary. Relocation is part of adaptation. Relocation is not hardship.

Seriously? Good grief.

400 years is a long time. Entire cities have appeared and disappeared in such period. How do you even know there will still be people living there?

Do you seriously think these people will be waiting 400 years before they have to relocate? Think again and try and have more empathy for your fellow human beings.

I have a lot of empathy for the people who you wish to condemn to a life of energy poverty because of your twisted sense of priorities. My question for you: why do you pretend to care about people when your pet policies suggest you really don't? Edited by TimG

You are actually 'twisting' my posts to suit your reasoning and it's not jiving, at least not with me.

Ah, the last time I was in the Keys they seemed to be in the same ocean that everybody else is in. They are kinda connected ya know. Look at an atlas. Thinking that a few attolls out in the Pacific are the only ones who will be affected demonstrates sheer ignorance of geoscience.
