A critical assessment of extreme events trends in times of global warming

Excerpts:

Abstract

This article reviews recent bibliography on time series of some extreme weather events and related response indicators in order to understand whether an increase in intensity and/or frequency is detectable. The most robust global changes in climate extremes are found in yearly values of heatwaves (number of days, maximum duration and cumulated heat), while global trends in heatwave intensity are not significant. Daily precipitation intensity and extreme precipitation frequency are stationary in the main part of the weather stations. Trend analysis of the time series of tropical cyclones show a substantial temporal invariance and the same is true for tornadoes in the USA. At the same time, the impact of warming on surface wind speed remains unclear. The analysis is then extended to some global response indicators of extreme meteorological events, namely natural disasters, floods, droughts, ecosystem productivity and yields of the four main crops (maize, rice, soybean and wheat). None of these response indicators show a clear positive trend of extreme events. In conclusion on the basis of observational data, the climate crisis that, according to many sources, we are experiencing today, is not evident yet. It would be nevertheless extremely important to define mitigation and adaptation strategies that take into account current trends.

To date, global observations do not show any significant trends in both the number and the energy accumulated by hurricanes, as shown in Fig. 1 and as claimed in several specific papers [13] for the USA, which

Fig. 1 Long-term trends in disaster losses, normalized to account for rising wealth and population, have not so far been attributed to climate change, but it has not so far been ruled out that climate change may have played a role.

Historical trend of the Tropical Cyclone frequency (above) and accumulated energy ([16]; updated data from http://climatlas.com/tropical/)Full size image

Particular attention should be paid to the IPCC statement which reports strong increase in the frequency and activity of tropical cyclones in the North Atlantic. To get more information on this issue, NOAA [17] analysed much longer time series (> 100 years) of Atlantic hurricane activity.

Existing records of past Atlantic tropical storms or hurricane numbers (from 1878 to present) indeed show a pronounced upward trend; however, the density of Atlantic shipping reports was relatively low during the first decades of this period: if the storms of the modern era (after 1965) had hypothetically occurred during those decades, a considerable number of storms probably would not have been observed by the naval observation network.

Therefore, after adjusting the time series to take into account the smaller observational capacities of the past, there remains only a small nominally positive upward trend of the tropical storms from 1878 to 2006. Statistical tests indicate that this trend is not significantly distinguishable from zero.

Furthermore, Landsea et al. [18] noted that the rising trend in Atlantic tropical storm counts is almost entirely due to the increase in only short-lived storms (< 2 days), which were most likely overlooked in the early parts of the record, as they would have had less opportunity for casual encounters with ship traffic.

If we look at hurricanes in the Atlantic basin, rather than all tropical storms, the result is similar: the reported number of hurricanes during the 1860s and 1880s was similar to nowadays and again there is no significant positive trend since that time. Evidence of an upward trend is even weaker for hurricanes hitting the coast of the USA, which show a slightly negative trend starting in the 1900s or late 1800s.

,

With increased Doppler radar coverage, population growth and increased attention to tornado reports, there has been an increase in the number of tornado reports in recent decades. This can create the misleading appearance of a growing frequency of tornadoes.

However, by consulting the time series shown in Fig. 3 [24], we realize that the increase in the number of tornadoes since 1950 is almost entirely due to weak events (EF0-EF1 in the advanced Fujita scale), those that in the past in many cases escaped the observation and which today are more easily identified thanks to a wide range of systems ranging from cell phone cameras to satellites and Doppler radars. In contrast, strong to violent tornadoes (categories EF-3 to EF-5 on the advanced Fujita scale), likely reported also before the Doppler radar era, show no increase over time.

While the increase in the frequency and persistence of heat waves can easily be explained by increasing global temperatures, the observed increase in tropical cyclones in the North Atlantic, as well as having unclear reasons as claimed by the IPCC [6], seems to be a local phenomenon and substantially due to better reporting as supported by NOAA and as we will better see in the paragraph dedicated to this type of phenomena. In other areas of the planet, a decrease in the same phenomena is observed and in still others no trend is observed, essentially bringing the global evaluations to a substantial temporal invariance.

Fearing a climate emergency without this being supported by data, means altering the framework of priorities with negative effects that could prove deleterious to our ability to face the challenges of the future, squandering natural and human resources in an economically difficult context, even more negative following the COVID emergency.

I wonder if the heatwave data is based on IPCC’s truncation of data by excluding pre 1950 information, thus eliminating Dust Bowl droughts and about 75% of US states high temperature records. Also eliminates much of Australia’s drought trends from the first half of 20th C.

Still it’s good to see some European scientists reporting against the political winds.

Everywhere you look, the Early Twentieth Century shows to be just as warm or warmer than today.

It should be warmer today, than then, because there is more CO2 in the air today, according to CO2 alarmists, but it’s not warmer today. Something is wrong with their assumptions.

Both weak hurricanes and tornadoes increases are likely to be enhanced observation artifacts.
Anyone who has ever watched local weather reporting in areas with thunderstorms leading to tornadoes will know how commonly the doppler radar will report a weak tornado that causes no damage on the ground. With better coverage for the doppler radar, such artifacts should be common.

Fretslider, the real issue is the burden of proof. If you want to make a case that other people should change their ways, the burden of proof is on you to show that they are causing damage. To quantify that damage. And to identify those to whom they are causing damage, too (in order that the compensation can be allocated to the right people).

Unfortunately, the climate alarmists have contrived to invert the burden of proof on this issue. But this paper seems to indicate a start on the way back towards reality and justice.

I have seen reports that 2021 had the fewest hurricanes globally since the start of the satellite era. However, that is NOT what is shown on the included chart.

Did I get taken by some fake news from our anti-alarmist side, or is there that much legitimate variance in the data series used for hurricanes?

If so, can anyone explain the cause of the variance?

Possible explaination: The Maue ACE plot was updated July, 2021. So it misses the latter portion of the year. When you are plotting annual data that is going to be a big deal.

This is great but the problem with this, like most of what we see, is that it starts in 1970. That isn’t long enough to see any real trends or cycles. Admittedly this is only one location, but here are the temperature trends for the daily high temperature for each day of the year from 1900 to 2020, at Cornell University’s experimental farm in upstate New York.

Before you post articles and comments like this, you need to have a meeting on a shingled roof wearing summer clothes with no shoes. Have an ambulance on standby because you will need it.

Would the 70-90 degree Celsius roof be warmer than the 30 deg. C atmospheric temperature?

Hot excited atoms and molecules always transfer that energy to cold. Is that warming the atmosphere? The answer is undeniably yes.

Air conditioning is in fact refrigeration, why would we have a heating system and refrigeration in the same application.

Here is solar impact in the winter superheating the atmosphere. It is a heat emission, not GHG emission. In the summer the AC unit will use 1000s of watts per hour per building responding to symptoms.

That’s very misleading, Professor Curtis, if you are in fact a professor.

I think it’s time to flip the script on this claim that citizens that disagree with CAGW are seditious. Realists should form a class action suit to sue the global warming/climate change supporters with sedition. Vet everything out in a court of law in front of a jury. I think it will be the trial of the century and the truth will prevail because the whole CAGW hypothesis is founded on junk science. CO2 is not an evil pollutant but rather a giver of life to our carbon based existence.

This does not mean the world isn’t warming and that problematic sea level rise is not a threat. It only means that climate activists have been mostly wrong with their claims of worsening extreme weather. In the past few years many climate activists stopped making claims of tornadoes getting worse, although they’re still claiming (incorrectly) that the jet stream is getting less stable, temperature variance is getting greater, and that global warming caused the extreme winter weather in Texas in February 2021.

In my lifetime and most likely yours, if you’re over the age of 7, there has indeed been a slight warming which has likely contributed to increasing agricultural output. A global milding, with somewhat higher low temperature readings at night and in winter.

Sea level rise is essentially unchanged in its very slow and steady rate since the end of the Little Ice Age. That this ~2mm/yr rise can reasonably be described as “problematic” or even “potentially problematic” is not obvious to me. (An incredibly gradual change that has been successfully adapted to for going on two centuries, is likely not suddenly going to become a crisis).

The study discussed here does not address these topics, though. Is that what you meant Donald?

 In the abstract, I find these two phrases in conflict:

1: None of these response indicators show a clear positive trend of extreme events. And . . .

2: It would be nevertheless extremely important to define mitigation and adaptation strategies that take into account current trends.

Should we assume they mean the most extreme scenarios by models of “climate” 80 years from now? The interesting word in the 2nd statement is “define”. Defining may be useful, but as for doing, I think not.

Observational data = SURFRAD

Attached is a slide for SURFRAD data at Table Mountain, Boulder, CO 6/18/21. There are 1,440 1-minute data points.

Column 13 is downwelling solar insolation, “dw_solar real” or the 160 on the K-T diagram.
Column 14 is upwelling insolation, “uw_solar real” or the 63 on the K-T diagram.
Column 25 is the difference between the two or what I have demonstrated is the non-radiation, kinetic energy, heat transfer processes and NOT “back” radiation.

Column 17 is the downwelling IR, dw_ir or the 333 on the K-T diagram.
It’s not real.
Column 20 is the upwelling IR, uw_ir, or the 396 in the K-T diagram. This is the theoretical, S-B BB result for the GROUND temperature not the 10 m “surface” air temperature. In this case, Column 14/column 20 is the emissivity. Just as with the K-T et. al. balances applying this emissivity to the raw uw_ir measurement makes the uw/dw_ir loop disappear while the balance remains.
It, too, is not real.

A plot of the ground versus 10 m air temps is revealing.
During the night the 10 m temp is slightly higher than the actual ground temperature.
As day breaks the ground temperature rises much faster than the 10 m temp and during much of the day is much higher than the 10 m temp.
The ground is a heat sink that absorbs energy during the day and releases during the night.

When the emissivity is applied correctly there is no GHG energy loop, no RGHE, no GHG warming, no CAGW.

Yet they’ve never, never proven that any weather events or “Climate Change” observed are outside Natural Variability.
The Doom and Gloom comes from politized “science”, not science.

Here in NZ some climate experts declared that a recent flooding event was 15% worse due to human caused climate change.
They seemed pretty convinced. I don’t think they even used any of the ‘will’, ‘could’ etc. weasel words.

You can say whatever you choose, arm waving isn’t proof

Arm-waving isn’t even evidence.

I think what we can say for certain is that these climate experts’ rationality is 15% worse due to human caused climate change.

The personal behavior of 1% of the U. S. population results in their CO2 footprint being 50 times that of the average of the other 99%. Were this small group to only emit 25 times the CO2 of everyone else, overall U. S. CO2 emissions would immediately, not over years or decades, decline 17%. Oddly, the people are not informed of this. Maybe because so many of this small group are AGW scammers?

‘On the Basis of Observational Data, the Climate Crisis…is Not Evident Yet’
Preoccupant!…

Are there any model outputs to confirm these observational data?

Are there any model outputs to confirm these observational data?

Yes.

Just taking “hurricanes / tropical cyclones” as an example, when it comes to how the Earth’s climate system “will” react to increased atmospheric CO2 levels by the end of the century the models fall into 3 sub-groups :
1) Those that “project” an increase in frequency and/or intensity (of future hurricanes)
2) Those that “project” no statistically significant change in frequency and/or intensity
3) Those that “project” an decrease in frequency and/or intensity

There will always be “model outputs” that end up “confirming” any and all “observational data” …

When considering if on balance there is evidence for the ‘climate crisis’, has anyone considered the effect of multiple hypothesis testing?

I would expect this is necessary for both the number of categories of impact considered but also the spatial aspect.

If I look at enough categories of impact eventually one or more of them will be statistically significant on it’s own by simple chance (i.e. 95% equates to 1 in 20 being by chance).

Similarly for the spatial aspect, if I divide the world into enough regions and locations, some of those will show a change in the direction I’ve declared as a climate change signal by simple chance.

Add in the interaction of both the number of categories of change, and the number of places I’m looking for those changes, and it would seem the bar for statistically significant change should be much higher than is typically presented in an attribution study.

Even the “yet” at the end of the title truckles to the assumption that there will inevitably be a “climate crisis” – if not now, then soon.

With everyday reporting of every climate crisis scenario that “may” happen or that is ‘predicted’ to happen; most people don’t need evidence that, ” it hasn’t happened yet”. The mirage of crisis has been before the eyes for decades with ever increasing veracity and frequency. They just won’t believe reality.
