We are broiling, and drying out over a big portion of the country. And now, Richard Muller, a global warming skeptic has announced his conversion to true believer after the Berkeley Earth Surface Temperature Project (funded partly by the Kochs which should add credibility for the skeptics) concluded that GW is real and man made:
Our results show that the average temperature of the earth’s land has risen by two and a half degrees Fahrenheit over the past 250 years, including an increase of one and a half degrees over the most recent 50 years. Moreover, it appears likely that essentially all of this increase results from the human emission of greenhouse gases.
Assuming they are even half right, what does this mean for us and the economy? I long ago concluded that it is too late to avoid getting slammed by GW. I am optimistic that technological advances will allow us to adapt but the changes should force some major shifts both good and bad. I can't see how it calls for any changes in the standard diversified portfolio advice but maybe some of you have other thoughts?

First off, that is 'weather', not 'climate'. We had a very mild, cool summer here last year, and I wouldn't use either as any indication of long term climate trends.

I recently read "Super Freakonomics" and there was a very interesting chapter on using technology, not to adapt, but to actually reverse global warming. Here a brief clip from an article:

Are 'SuperFreakonomics' Authors Wrong on Global Warming? - TIME

The authors visit Nathan Myhrvold, the brilliant former chief technology officer of Microsoft and co-founder of Intellectual Ventures, a private think tank. Myhrvold and his staff have the idea to build a giant "garden hose to the sky" that would pump liquefied sulfur dioxide into the atmosphere. Scientists know that increasing SO2 in the air deflects sunlight, which cools down the earth; when Mount Pinatubo in the Philippines exploded in 1992, for instance, the SO2 sent into the atmosphere created a brief global cooling spell. Levitt and Dubner advocate pursuing this geoengineering scheme, which could potentially avert a hotter world for pennies on the dollar, compared with the long-term work of shifting to a low-carbon economy.

I highly recc you read the whole chapter in the book. It really made a lot of sense to me. They have all this data about SO2 and these volcanoes - it's like running an lab experiment on a global scale. And it is so much cheaper, easier, faster than reducing CO2 (and what does that do for the CO2 out there?).

As a parallel, I like to think about being in a car, realizing you are going too fast, and there is a stopped truck blocking the road ahead. Do we say "Well, I used the engine and gasoline to speed up, so the only way to slow down is to slow down that engine and reduce gas consumption"? No, we hit the brakes! We use different technology to slow down than we did to speed up. But it seems to me that most people are saying that if man-made CO2 production is the cause of GW, the only thing we can do is reduce man-made CO2 production. That is very costly, and I think most studies show the results to be minimal.

So maybe this SO2 technology is what we should watch, and maybe invest in? Also, the SO2 technology is controllable - need more, add more; got enough, you can slow it down.

I wonder if the skeptic's A/C went out on a hot and humid day before he went through the conversion? :LOL:
 
donheff - you might be 'over-selling' his conversion a bit. From that NYT article:

These facts don’t prove causality and they shouldn’t end skepticism, but they raise the bar: ....

It’s a scientist’s duty to be properly skeptical. I still find that much, if not most, of what is attributed to climate change is speculative, exaggerated or just plain wrong. I’ve analyzed some of the most alarmist claims, and my skepticism about them hasn’t changed

Hurricane Katrina cannot be attributed to global warming. The number of hurricanes hitting the United States has been going down, not up; likewise for intense tornadoes. Polar bears aren’t dying from receding ice, and the Himalayan glaciers aren’t going to melt by 2035. And it’s possible that we are currently no warmer than we were a thousand years ago, during the “Medieval Warm Period” or “Medieval Optimum,” an interval of warm conditions known from historical records and indirect evidence like tree rings. And the recent warm spell in the United States happens to be more than offset by cooling elsewhere in the world, so its link to “global” warming is weaker than tenuous.

I'm sure I could google and find a convert in the other direction. Would that make it a wash?

We have had thunderstorms with absolutely torrential rains during part of every day in July so far, I think. We have had minor flooding frequently, and even had more than minor flooding on at least one day. On that day, some people had to swim from their completely submerged cars or were rescued, for example. Still, I do feel sorry for those who are experiencing a drought this year. We had that last year and I must say, I prefer the rains when it is not flooding.
 
Have we considered that the cause of warmer days (that is a fact) might be attributed to both climate change and weather patterns?

Not to sound too depressing, in comparison, it is possible, say a 100 year old person's decline in health might be attributed to old age and disease. It doesn't have to be either or.

I do know for certain that when I was a kid, it was almost always cold during Christmas and warm during July 4th.

The warming and cooling cycles of the past few centuries match the sunspot cycle duration. Human adaptation to changing climate has been the norm for millenia.
 
The 'conversion' wasn't due to the temperature on that day, or this summer. It was due to the research done.
That said, weather is not equal to climate, but climate does affect weather.
Simply track the number of high temperature records vs the number of low temperature records over the planet and that should give you a pretty good idea.

As for Freakonimics, great books! Lousy science. Injecting large enough SO2 into the air will cool things. But the SO2 needs to be replaced often. And if CO2 continues to rise, you need more and more SO2. And of course, you then also have the consequences of the SO2.

As to what to do with finances? Many of the things most of us already do. Keep out of debt. Be prepared to pay more in insurance (medical and other types).
And as a suggestion to those looking to move, don't move to a desert or near desert, and don't move into a coastal city at or below sea level.

For anyone that is interested in what skeptical scientists think, and how they work, check out Global Warming and Climate Change skepticism examined

I don't know enough to know if their science is good or not, but the IV team seems like a pretty smart bunch.

IIRC, the SO2 needing to be replaced was a benefit. If something didn't go as planned, they could shut off the flow, and it all dissipates in a relatively short time. The plan was to pump a continuous stream. They even said we could (at greater expense) use the existing SO2 output from some existing coal plants.

I think it deserves further research - even if it isn't the best/only answer, it might help (assuming this is a problem that needs fixing) until we develop a better solution?

This s incorrect. There are some short term trends that are somewhat similar but the don't hold up overtime.
A more detailed discussion can be found at Solar activity & climate: is the sun causing global warming?

That article does not address what I described. I agree there is no apparent climate correlation with sunspot count, but instead there is correlation with sunspot cycle duration.

Most certainly. And it is quickly reversible, so you are exactly right it is one of the benefits.
It is also is definitely worthwhile to investigate further. I would be ver curious about how many tons of SO2 it would take, and to what altitude, and of course what the initial and then increasing costs would be.

As for smarts, I think the Freakonomics guys are incredibly smart. Likewise, penguins are incredible swimmers. Doesn't mean a penguin would win a tree climbing contest;)

Thanks for the links. The first does seem to focus on sun spot cycles as a proxy for how much energy we get from the sun.
Regarding the specific concept of he sunspot cycles, this may more directly address your question. I actually found the exact same erroneous graph in both articles which I found interesting. The link you showed mig do well to update the graph corrected by the original source of the graph.
What does Solar Cycle Length tell us about the sun's role in global warming?
 
Don't worry about it. We'll know in a hundred years or so who was right, and whether or not we should have done something about it.

While we are waiting for the results, I'll just focus on shorter term goals like maximizing my returns and minimizing pesky unwarranted capital expenses.

OK, but I wasn't really commenting on the Freakonomic's guys science credentials or smarts, I was commenting on the team they were reporting on:

Intellectual Ventures - Wikipedia, the free encyclopedia

http://en.wikipedia.org/wiki/Nathan_Myhrvold

He could be all wet too, but I think he's worth a serious listen. I think we are mostly agreeing on this, no?

-ERD50
 
I have read the Freakanomics books so I undoubtedly came across the SO2 idea. I have read of other approaches that might reverse the trends although I can't remember specifically what they were. I would include all of them in my hope that with technology we can "adapt" to the reality of GCC since I don't think a slow down of CO2 buildup (while probably advisable) will get us off the hook - we are past the tipping point on that dimension. Despite my optimism about tech I would be leery of investing in specific technology. My track record of predicting which ones will pan out is lousy. Not sure if a sector fund is any more likely to be a star.

As to Mullen's conversion, it seems pretty complete. He says the science has convinced him that GCC is both real and almost entirely man-made. If that isn't a conversion from skepticism, what is? The fact that Katrina and current local weather isn't attributable to GCC is a red herring. I have not read much in the way of scientific opinions that they are. The important thing about this to me is it should help convince all thinking people that GCC is real and that we should start seriously evaluating what the impacts may be and how we should address them.

I should probably walk back my opening sentence about this summer's hot, dry weather. I don't think there is any basis to assume it results from from global warming, it just helps get us thinking about it.

Also very interesting!
On 5 minutes of searching I still couldn't find anything on how much SO2 was needed on an annual basis. The closest I got was a quote from him saying 'not as much as you might expect'.
The location choice (the poles) I find very interesting. For maximum dispersion I would think you would want mid latitudes. However, maximum dispersion may not be the affect he is going after.
It is interesting. Even if it is workable, I would be Rey concerned about unintended consequences.
 
I am convinced that the world is warming. I don't know enough to say if is is anthropogenic or not, although I suspect it is. I do know that some of the proposed solutions -- shift from carbon based energy to renewable energy, use all energy more efficiently, pollute less -- all seem like good things to be doing regardless.
 
Where I am (Illinois) we are finally receiving a little respite from the heat. Still sad to look up at the occasional grey sky but no rain forthcoming.

I read articles about La Nina and El Nino effects but am too uninformed to know what to think.
 
Frankly, I think we have reached the point of no return. I don't see the collective will to remedy our problems in dealing with a warming world.

I don't think you see much 'collective will' because there isn't a whole lot of 'collective knowledge and assurance' about what exactly we should do, and how much affect it will have. Throw the 'Tragedy of the Commons' on top that, and it isn't too surprising.


I don't know if the IPCC has updated it's reports, but the last time I tried to dig through them, they seemed to say that even if we took very drastic measures today, cutting fossil fuel use to near zero, the range of unknowns about the effects is so large - we might not even know if it helped or not, even after the fact. IOW, some of their best case predictions for 'do nothing', overlapped with their worst case predictions for 'change everything drastically, now!'.

I'm not so sure waiting is such a bad thing. We hopefully keep learning more, and there may be solutions down the road that are much better and affordable than any solutions today. If anything, I do think we should focus on conservation. I think that is the low hanging fruit. It seems to me that conserving 10% of our energy is far easier, and probably an economic plus than 'investing' in generating 10% of our energy from 'green' sources. Every green source has some environmental impact, but a Mega-Watt-hour not used is a Mega-watt-hour that doesn't need to be generated. I don't see how we can get greener than that.

OK, some energy conservation takes some offsetting energy (adding insulation, etc) - but there is a lot that can be had for free, if we set our minds to it. My electricity use is in the lower quintile of our neighborhood (according to a utility report I got). We aren't living like the Amish, none of my appliances are expensive 'low energy' types, yet we are at ~ 1/2 the energy usage of the average here - if that is a reasonable bell-curve, there are some using 4x what we do! I can't imagine where it goes (pool pumps? pool heaters? A/C & heat on at ridiculous levels?).

The sunspot cycle does affect energy gained from the sun but it's an 11 year cycle. How does that explain the temperature rise over the past 50 years (see OP link)? Or the past decade, for that matter.

The current cycle ends in 2020, which means we're not at a peak yet. This indicates that we could see even higher temperatures until ~2015. Don't buy midwest farmland yet!
 
For some thoughts on the the hot weather most of you have been experiencing, from somebody who actually understands the science behind weather and climate...

Cliff Mass Weather Blog

Read the July 29 entry.

Thanks for that link. While I'm not knowledgeable enough to know for sure, that sure impresses me as being informative and unbiased, and I do think I have a very sensitive BS detector.


I see that donheff clarified that he isn't associating this recent weather with climate change, that it just got him thinking about. It had the same effect on me, running my AC more this year than probably the past 5 years combined, and it isn't even August yet - but then again, last year was exceptionally cool here. So it does draw your attention to it.
