New Study: Warmer Temperatures Associated With A Reduction In Storms, High Winds

The claim that rising global surface temperatures will induce more storm activity is contradicted by observations.

Scientists reporting on the contrasting albedo effects of clouds in the Northern vs. Southern Hemispheres (Blanco et al., 2023) assess clouds have a “profound” effect on the global radiation budget and thus our climate.

The Southern Hemisphere is cloudier than the Northern Hemisphere at the same latitudes, and hence the sea surface temperatures are colder.

In contrast to the claim that warmer temperatures fuel more storms and stronger winds, cloud-albedo-induced colder temperatures are viewed as a trigger (“cloud-controlling factor”) for the stronger Southern Hemisphere’s wind speeds and storm tracks.

This is the opposite of what is claimed by proponents of anthropogenic global warming, as it implies we get fewer or less intense storms as the surface warms.

Theoretical physics also supports the observation that warmer surface temperatures lead to fewer, not more, storm events. Heat reduces the capacity for the hydrological cycle to do work, or power “large-scale atmospheric circulation or…very intense storms” (Laliberte et al., 2015).

Indeed, long-term storm records also support the conclusion that colder periods have more and stronger storms, and warmer periods have fewer and less intense storms. (Degeai et al., 2015).

The alleged negative effects of having a warmer world are, once again, contradicted by observations.

Fauci, Fear, Balance and the Grid

From Climate Etc.

by Planning Engineer (Russell Schussler)

Reflecting on the U.S. response to the covid pandemic, Dr. Fauci provides some important insights on managing complex risks – with relevance to climate change and the electric grid transition.

Dr. Fauci discussing past covid measures was recently quoted as saying,

“(W)e looked at it from a purely public-health standpoint. It was for other people to make broader assessments—people whose positions include but aren’t exclusively about public health. Those people have to make the decisions about the balance between the potential negative consequences of something versus the benefits of something.”

I was surprised to hear that Dr. Fauci did not think that public health should have been in total control of the pandemic response.  But he is right. We needed diverse experts providing input and impacting policy choices – some who worry about public health, others who worry about individual health, others who worry about children, and others well versed on the economic impacts of it all.  Doing everything possible to stop the spread of covid, all other costs and consideration be damned, should have been expected to reduce the overall well-being of society and provide grossly suboptimal outcomes.  Focusing solely on covid risks was likely counterproductive even for those most at risk from covid.

In the U.S., the balanced path Dr. Fauci is now advocating was not seriously pursued during the pandemic. With the Covid panic, it seemed public health took over with one over-riding goal.  Advocates for individual health and individual health care found few available forums and inroads to appeal to and  impact policy makers. Appearing to be against the central narrative of those in power may have had severe consequences for individuals and organizations. In hindsight, many see that balancing competing views and values would have better served us all. In focusing so exclusively on the threat of covid, we increased our risk from so many other threats.  Many now understand that our “best” scientific understandings should be subject to challenges.  It certainly seems we needed “other people” to speak up, but those voices did not find the platforms they would need to influence policy and direction. 

There are some similarities here with “experts” who are driving policy as relates to the climate “emergency” and the emerging plans for net zero.  My recent posting discussed reasons why utility grid experts were silent while policies were enacted that called for large increases in wind and solar power.  It’s fairly clear that insufficient numbers of  policy makers want  to  hear of  the potential negative consequences related to increasing penetration levels from wind and solar.   Perhaps our experience with covid regulations can shed some light on the discussions that should occur around grid policies.  Both covid and net zero efforts are dominated by an overfocused group of experts, crafting an overly simplistic narrative to guide policy makers, the press, and much of the public. These narrow experts and their followers are largely unaware of the large negative externalities that result from their initiatives.  Public health was worried about public health, not individual health or the economy.  Many of those now driving the net zero mobilization are focused on CO2 reduction, not grid reliability or the economy.

Counter to Dr. Fauci’s calls for “other people to make broader assessments”, in reality often when disaster or emergencies are proclaimed the voices of the “other people” are marginalized, ignored, discredited and/or demonized. Instead of allowing diverse voices to “balance” concerns, those proclaiming disaster become self-righteous and authoritarian, arguing that other voices are at best wasteful distractions and at worst the work of those with selfish or sinister motives. Such sentiments can capture policy makers, the media and the public.  The resultant mob wants to build consensus for a complex and highly uncertain problem,  and they promote the idea that anyone challenging “the consensus” narrative is a dangerous threat.

The fear-based, narrowly focused  public health approach to covid avoidance, largely to the exclusion of all other concerns, seemed to get worse as it trickled down to the broader public. Over-reactions were common as skate parks were filled with sand and beaches were closed.   In my active 55+ community, our board had regular visits from public health workers. They focused on obscure risks and studies like this one recommending walkers beware of slipstream transmission.  They locked up our outdoor recreational amenities, took down nets and encouraged isolation way longer than made sense. Arguing against their efforts in favor of a two-pronged strategy of avoiding covid and also encouraging individual health, was seen as a selfish and ignorant position by many.  They insisted they were following “experts” advice, but it was only from one narrow perspective from one narrow field of expertise.  The masses were largely swayed by unchallenged public health concerns such that for many staying home, watching tv and drinking were seen as the responsible thing to do.  Unfortunately, the health consequences of that strategy in older populations were generally not good.

The fear-based calls for a “green” grid has followed a similar path.  The narrative coming from leaders in this area influence  regional and local authorities as well as individuals.  Many areas over-subsidize solar for the wealthy at the expense of the poor.  Ridiculous “green” projects garner support.  As with covid, those challenging the “green” narrative are suspect.  “Forget the economy.  Forget the negative impacts associated with wind and solar. Forget the cost and reliability implications or what it might do to our standard of living.  We are facing a calamity.” When technical claims about the shortcomings of intermittent asynchronous wind and solar are met by exclamations about how bad climate change might be, you realize that fear has pushed rational discussion aside. Hopefully “green” experts and advocates might  one day soon see the wisdom of Dr. Fauci’s statement rewritten here for them:

“It is for other people to make broader assessments… Those people have to make the decisions about the balance between the potential negative consequences of something (asynchronous intermittent generation) versus the benefits of something (economic reliable energy)”.

Those calling for economics and reliability to be considered along with social responsibility and “green” concerns should not be seen as the enemy. They should play an important role in the broader assessments of energy policy. They should not be seen as shills of industry or deniers of science but rather responsible experts helping achieve balance in the policy process. 

There doesn’t seem to be much evidence that Dr. Fauci actually sought to encourage balance around the bigger issues as covid policies evolved.  But his more recent reflections provide rock solid good advice.

Those people have to make the decisions about the balance between the potential negative consequences of something versus the benefits of something.

We may one day hear “green” experts cry out, after grand experiments fail, that, “I was only talking about what green energy could do, it was up to others to provide balance and publicize the short comings of the technology.”  It will be too late then.  Let’s challenge all “experts” now to show their commitments: 1) to balance, 2)  to addressing their critics, 3) to understanding the limitations of their knowledge,  and 4) to help cultivate an appreciation for how other experts might help better understand  potential negative impacts from their proposed actions.

Conclusions

Promoting healthy debates with a variety of perspectives around critical issues, such as a potential  grid transformation, is the best course for developing sound policies.  Unfortunately, we seem to be moving farther away from such hopes, as those in control argue for our/their “best understandings” and help stifle anything that might cast a shadow of doubt around their narratives .   When disaster is predicted, select “experts” take priority, opposition is hushed, and then balance is lost.  The overused recipe of proclaiming disaster, proposing a solution, declaring there is not much time, arguing that “misinformation” is harmful and then controlling the dialogue works against us all.  While it may get decisions and policies rolling, it is often not in the right direction and long-term needs and feedback mechanisms are frequently overlooked and ignored

As suggested by Dr. Fauci, in any major undertaking balance is needed.  It is far better to understood this in advance, rather than recognize it  in hindsight.   The justification for balance is summarized in this 2016 posting:

“The power system is a matter of extreme importance relating to economic development, quality of life as well as health and safety. In order to best meet the needs of any given area, it is necessary to balance the factors of economics, reliability and public responsibility. An imbalance in any area will lead to repercussions in other areas and may, in fact, prove to be counterproductive across all areas.”

Getting the power system right is important regardless of the threats posed by climate change. Climate change concerns should not trump a reliable economic grid.   In fact, quite the opposite, the greater the threat of climate change, the more important it is that we get power supply right. Climate change would not pair well with an unreliable, overly costly, unworkable energy system.  Focusing too narrowly on public responsibility (CO2 reduction, equity, social justice) without adequate concern for economics and reliability is a recipe for disaster.  Bring on the balance.

Oxford University’s Our World in Data falls for renewables industry spin

Campaigning group Net Zero Watch has called on Oxford University’s Our World in Data (OWID) site to withdraw its webpage on the cost of renewable energy.

In a letter to OWID’s director Max Roser, NZW’s Andrew Montford explains that the site is putting its reputation at risk by ignoring the highly transparent UK data in favour of numbers that are not replicable, and most likely to be based on “hearsay”.

Mr Montford said:

The UK is almost unique in having a high penetration of renewable energy and freely available financial accounts data. A series of reviews of this information confirms that the cost of offshore wind power is high, and hardly coming down at all. It is hard to comprehend why Our World in Data would ignore this hard data in favour of unsubstantiated spin from the renewables industry. Their page on the subject should be revised before anyone else is misled.”

Dear Dr Roser

Our World in Data (OWID) is usually a rather reliable source of information, so I wanted to draw your attention to what I believe is an uncharacteristically flawed article on your website. This is ‘Why did renewables become so cheap so fast?’, which examines the levelised cost of renewable energy.

Firstly, I should point out that the levelised cost of electricity (LCOE) isn’t actually data at all. In simple terms, LCOE divides the lifetime costs of a generator by its lifetime output, but neither of those figures are known until the generator closes down at the end of its life. So while the Capital Expenditures (capex) element of lifetime cost is knowable at the start, the lifetime Operational Expenditure (opex) and the output have to be modelled. So whether a site called Our World in Data should be discussing LCOE at all is worthy of consideration.

Where LCOE is discussed, the data used as input needs to be grounded in reality, the modelling assumptions need to be made clear, and caveats spelled out. This is not the case for the sources you cite. For example, while widely cited, the assumptions used by Lazard are demonstrably false. For example, for offshore wind, the version of the report you cite (version 13) claims a capital cost of £2.3-$3.5m/MW, roughly half the cost of offshore windfarms in the UK, and a third of the cost of the only (admittedly experimental) offshore windfarm in the US. As I have pointed out elsewhere, the assumptions for capacity factor and opex are similarly divorced from reality.

You also cite the International Renewable Energy Agency (IRENA), whose figures are similarly problematic, notably because they convert all their numbers into US dollars, giving them a large and entirely spurious downwards trend as a result of the appreciation of the dollar against most other currencies.

It’s not clear where Lazard and IRENA are getting their input figures from, but it’s unlikely to be anything that could reasonably be called ‘data’. IRENA is supposed to be global in nature, and Lazard are vague about whether their estimates are for the US or for the world. Either way, the majority of the financial inputs cannot be data because such information is not available for most of the world: word of mouth and/or developer announcements seem the most likely sources. In the UK, developer announcements are typically 15-20% lower than outturn cost.

The clear exception to this rule is the UK, where financial data is freely available for all offshore windfarms and many large onshore ones (as well as a few solar parks). This then is the only reliable data for estimating the levelised cost of renewable energy. I refer you to the paper by Aldersey-Williams et al. (2019) on the LCOE of offshore wind, which presents a very different story to the one in your article, and which has been replicated by others.

By basing your article on figures that can only be based on hearsay, rather than on empirical data, you are risking your hard-won reputation as a reliable source. I would advise you to revise the article accordingly.

With best regards
