What Is A 1000 Year Flood?

by P. Homewood, Apr 18, 2023 in NotaLotofPeopleKnowThat

We’ve all heard the terminology. An extreme event happens — a flood or heat wave — and soon after it is characterized as a “1,000-year event” (or it doesn’t have to be 1,000, it could be any number). This week I watched one of the world’s most visible climate scientists, Michael E. Mann, go on national TV and in process show that he had no idea what the concept actually means.

Let’s start by correcting that climate scientist who expressed a popular misconception (about which climate scientists should know better). A 1,000-year flood does not refer to a level of flooding that comes around every 1,000 years.

Climate Expert: The Misinformation In The IPCC, Part 1

by R. Pielke, Mar 29 2023 in ClimateChangeDispatch

Today, in the first of two posts, I explain how the IPCC made several misleading claims related to tropical cyclones.

The IPCC’s failures are both obvious and undeniable.

I will walk you through them in detail. Once again, I conclude that the IPCC needs reform. Mistakes can creep into massive assessments, to be sure, but the failures I document below are unacceptable. [emphasis, links added]

The first failure never rose above the depths of Chapter 11 of its AR6 Working Group 1 (WG1) report. The second is a bit technical and is much more significant – having made its way into the Summaries for Policymakers (SPMs) of both WG1 and the Synthesis Report released last week.

Before proceeding, let me reiterate that the IPCC is not just one report or one group of people. It is many things and comprised of many different people. Its products are of uneven quality, and even individual chapters in the same report can be of very different scientific quality.

For instance, in general, IPCC AR6 WG1 did a nice job on the physical science aspects of extreme weather, whereas IPCC AR6 WG2 was chock full of massive problems. …snip…

Rainfall, Cyclone Data Show No Clear Upward Trend, Contradict IPCC Claims

by P. Gosselin, Mar 19, 2023, in NoTricksZone

Feel helpless when trying to assess the veracity of “climate doom is looming” claims? Don’t give up trying to understand the relevant basics because you don’t need to be a scientist to do so.

There is a rather simple way to get an idea about what this is all about. Even without a scientific background, most people have at least a good common sense. And that’s all it takes to get a grasp of how energy flows back and forth between earth’s surface and the skies.

Today in Part 5, we look at the linkage between the allegedly CO2-driven rise of air and sea surface temperatures on the one side and the disconnect between these increases and their strangely weak to insignificant impact on rainfall and hurricane intensity”.

Preceding chapters see Part 1 1), Part 2 2), Part 3 3), Part 4 4).

Variability of cloud effects vs “greenhouse gas” effects

In the last chapter, we have seen that there are some discrepancies between the global warming trend as claimed by the official climate science and the local evolution of rainfall, which should be a direct consequence of higher temperatures since this causes more evaporation. This seems not to be the case e.g. for Germany, see Fig. 1:

Intense, Long-Lasting Heatwaves Unfolding At The Bottom Of The Ocean

by G. Dickie, Mar 16, 2023 in ClimateChangDispatch

Heatwaves unfolding on the bottom of the ocean can be more intense and last longer than those on the sea surface, new research suggests, but such extremes in the deep ocean are often overlooked.

A team of scientists with the U.S. National Oceanic and Atmospheric Administration has conducted the first assessment of marine heatwaves along North America’s continental shelves.

They found that these bottom heatwaves ranged from 0.5 degrees Celsius to 3C warmer than normal temperatures and could last more than six months — much longer than heatwaves at the surface.

“We simply don’t have a ton of instruments on the ocean bottom along continental shelves,” said study co-author Dillon Amaya, an NOAA climate scientist. “The ocean is a powerful thing. It destroys instruments that we have in the water for too long.”

Surface heatwaves can be picked up by satellites and can result in huge algal blooms.

Hurricanes Are Getting Stronger (But Only In Computer Models!)

by P. Homewood, March 1, 2023 in NotaLotofPeopleKnowThat

…

The new study uses computer models to assess Atlantic storms going back to 1949, and to peer into the future to see what storms will look like in 2100. The authors, climate scientists at Princeton University, found that the flood and wind risk posed by storms has steadily increased.

The problem will only get worse in the coming decades. “The frequency of intense storms will increase,” explains Ning Lin, a climate scientist at Princeton University and the lead author of the new study.

Executive summary

It is widely believed that hurricanes are getting worse as a consequence of climate change. This belief is fuelled by the media and some politicians, particularly when a bad storm occurs. This be- lief is reinforced because the damage caused by hurricanes is much greater nowadays, thanks to increasing populations in vulnerable coastal areas and greater wealth more generally.

But is this belief correct, or is it a misconception? This study has carefully analysed official data and assessments by hurricane scientists, and finds:

• 2021 and 2022 recorded the lowest number of both hurricanes and major hurricanes glob- ally for any two year period since 1980.

• The apparent long-term increase in the number of hurricanes since the 19th century has been due to changes in observational practices over the years, rather than a real increase.

• Data show no long-term trends in US landfalling hurricanes since the mid-19th century, when systematic records began, either in terms of frequency or intensity.

• Similarly, after allowing for the fact that many hurricanes were not spotted prior to the sat- ellite era, there are no such trends in Atlantic hurricanes either.

  • Globally there are also no trends in hurricanes since reliable records began in the 1970s.
  • Evidence is also presented that wind speeds of the most powerful hurricanes may now be overestimated in comparison to pre-satellite era ones, because of changing methods of meas- urement.

• The increase in Atlantic hurricanes in the last fifty years is not part of a long-term trend, but is simply a recovery from a deep minimum in hurricane activity in the 1970s, associated with the Atlantic Multidecadal Oscillation.

These findings are in line with those of hurricane scientists generally, as well as official bodies such as NOAA and the IPCC.

Climate Expert: What The Media Won’t Tell You About Tornadoes

by R. Pielke, Feb 13, 2023 in ClimateChangeDispatch

This is the latest post in an ongoing series, titled “what the media won’t tell you about…”, which is motivated by the apparent systemic inability of the legacy media to play things straight when it comes to extreme weather and disasters.

Climate change is real and important, but its importance is not an excuse for the pervasive climate misinformation found across the legacy media. [emphasis, links added]

Here are the previous installments in the series, which are among my most popular posts and which have gone unchallenged.

What the media won’t tell you about…

Today’s post focuses on U.S. tornadoes. This year so far has seen a lot of tornadoes — 178 were reportedthrough February 11th, the 2nd most since 2005 and well above the 2005-2022 mean of 66 to date.

Of course, nowadays wherever there is extreme weather, journalists rush to claim a connection to climate change no matter what the science actually says.

For instance, after a tornado outbreak last month, the Associated Press reported that the tornadoes had been “juiced by climate change.”

Similarly, The Washington Post said that in the past it was difficult to tie tornadoes to climate change but now, “science is accumulating to support the linkage.”

Neither reported any of the data and science I share below. So, let’s take a look

The Great Famine of the 21st Century

by D. Siegel,  Nov 29, 202 in Shortfall

…

…

The true tragedy

The problem isn’t the future. The problem is what we’re doing right now. Today, humans spend more than $1 trillion every year on decarbonization, which will most likely have no measurable effect on our future climate. But it does raise the price of energy, and the current virtue-signaling environment prevents people in the developing world from reaching the standard of living we take for granted.

Today, life expectancy in sub-Saharan Africa is 60 years — the same as it was in the United States in 1935. Today, about 60 percent of sub-Saharan people are farmers — the same as in the US in 1860. About 500 million people in Africa live in extreme poverty. According to the World Bank, half the countries in Sub-Saharan Africa have poverty rates higher than 35%.

And yet, that same World Bank won’t lend them money to build a reliable energy grid. The United Nations and the World Economic Forum are forcing Africans to install solar and wind projects that can’t help them cook dinner, so they continue to burn trees, charcoal, and dung, destroying forests and dying of lung diseases. They are — right now — being forced to live lives we lived in 1850.

Yes, you say, but prices of solar panels are coming down! Imagine you have a car that drives really well whenever the sun is shining or the wind is blowing. No batteries, nothing, it just works. It’s not even that expensive, and it is magically zero emission. Now, can you get rid of your regular car? Or do you need to have your own back-up car for whenever the sun isn’t shining or wind isn’t blowing? You might think you could just rent or use an Uber then, but that’s exactly when everyone else needs a car, too, so you actually have to maintain your existing car, pay the insurance, make sure it’s always available, for those times when your renewable car isn’t possible and the Uber is taken. That’s twice as many cars, no matter who owns them. That’s not “sustainability.”

Summary

As you have just learned, we live in the safest century to be alive. We are more protected against natural disasters than ever. And we are being lied to about CO2 and climate.

This isn’t easy for a lot of people to hear. It has become a matter of tribal and political identity. I know. In 1991, I wrote a book about how CO2 was changing the climate. But then I dug deeper and realized not everything was as it seemed. When I started to tell others the science wasn’t settled, I lost quite a few friends. If you have read this far, thank you for being brave. I invite you to take the next step at Climatecurious.com.

An Inconvenient Tree: Is Climate Change Driving Worse Floods

by E. Worrall, Nov 27, 2022 in WUWT

Does evidence of past extreme floods invalidate claims that climate change is making floods worse?

…

…

 

Could volcanic activity be a contributor to major floods in Australia? Australia is on the South Western edge of the Ring of Fire. While the Australian mainland is not very volcanically active, there have been some spectacular eruptions in our neighbourhood, such as the infamous Krakatoa eruption in 1883, or the 1815 Tambora Eruption, which is blamed for causing famine in the United States in 1816, “The Year Without a Summer”.

A notable volcanic eruption occurred at the start of 2022 – The Hunga Tonga eruption. JoNova published an intriguing comparison between the volcanic ash distribution from the Hunga Tonga eruption in January 2022, and 2022 rainfall anomalies across Australia. Hunga Tonga was light on sulphates, but the blast threw unprecedented amounts of water into the stratosphere. Where I live, on the Southern edge of the volcanic debris distribution, we’ve had some spectacular sunsets over the last year.

The apparent overlap between rainfall anomalies and volcanic debris could be a coincidence – but the comparison is visually intriguing.

An Extreme(ly Nice) Summer

To pretend that winter storms are an example of Britain’s weather becoming more extreme is utterly dishonest, as the Met Office’s State of the Climate 2021 clearly showed that wind storms have grown less frequent and intense over the years since peaking in the 1990s.

97% Consensus on Climate Change? Survey Shows Only 59% of Scientists Expect Significant Harm

by WUWT, Nov 9, 2022

Humans are likely causing some warming, but substantial scientific disagreement exists on whether there will be significant impacts

ARLINGTON HEIGHTS, IL (November 8, 2022) – A new poll of scientists conducted by Fairleigh Dickinson University found that only 59 percent of respondents think global climate change will cause “significant harm” to the “living conditions for people alive today.” That is far short of the “97 percent consensus” narrative pushed by climate alarmists and their media allies across the globe.

The survey, conducted in September and October 2022 by Fairleigh Dickinson University and commissioned by The Heartland Institute, polled only professionals and academics who held at least a bachelor’s degree in the fields of meteorology, climatology, physics, geology, and hydrology.

The key question of the survey asked: “In your judgement, what will be the overall impact of global climate change on living conditions for people alive today, across the globe?” Fifty-nine percent said “significant harm.” Thirty-nine percent said either “significant improvement,” “slight improvement,” “no change,” or “slight harm.” Two percent were not sure.

Among respondents with the most experience – those at least 50-years-old – less than half expect significant harm for people alive today. Scientists 30-years-old and younger were the only age group for which more than 60 percent expect significant harm.

Like prior surveys of scientists, the new poll shows the vast majority of scientists agree the planet is warming. On average, respondents attributed 75 percent of recent warming to human activity. More importantly, scientists disagree among themselves on whether future warming will be much of a problem.

The poll also found only 41 percent of respondents believe there has been a significant increase in the frequency of severe weather events. The majority say there has been no change or only a slight increase.

In reality, objective data show hurricanes, tornadoes, wildfires, drought, and other extreme weather events have become less frequent in recent decades.

Let’s Talk About Real Climate Cataclysms

by P. Driessen, Oct 26, 2022 in ClimateChangeDispatch

The climate crisis! Save our planet! Stop using fossil fuels! The ranting never ends.

Present data show that hurricane frequency and intensity are not increasing, and tornado activity has declined significantly since 1975.

Offer clear evidence of past, recurring major climate changes, including a widespread Little Ice Age from 1300 to 1850, a 2,400-year-old forest emerging from beneath a melting Alaskan glacier, a 5,200-year-old mummified traveler frozen on a once-nearly-ice-free Italian Alps trail – and they respond, Shut up! The climate crisis! The science is settled! Stop using fossil fuels! [bold, links added]

Fine. But take a few minutes to ponder REAL climate disasters: the Pleistocene Ice Ages.

And then ask Michael Mann, Al Gore, John Kerry, and the rest of the climate cataclysm cabal to explain exactly how carbon dioxide and a few other greenhouse gases caused those massive ice sheets to grow and melt, multiple times. Just CO2 and GHG, all by themselves. They can’t do it. The CO2-driven crisis is a fable.

Widespread glaciation began some 1,800,000 years ago in North America and Europe, and about 800,000 years earlier on other continents. There were at least four, possibly five, major glacial periods, interspersed with warm intervals (like the one we’re in now) during which the glaciers mostly melted.

That last glacial epoch is named the Wisconsinan because some of the most exemplary features are in my home state. It marks the furthest extent of glaciers southward into the United States and east and west across Canada.

LA Times reveals 2020 CA Wildfire CO2 Wiped Out 18 Years of the State’s Emissions Reductions

by L. Hamlin, Oct 22, 2022 in WUWT

The article notes that “researchers estimated that about 127 million metric tons of carbon dioxide equivalent were released by the fires, compared with about 65 million metric tons of reductions achieved in the previous 18 years.”

The Times article provided the usual climate alarmist hype that “climate change” is responsible for the California’s increased wildfire damage noting:

“Forests have long played a role in that system, with large trees sequestering carbon and helping to alleviate some emissions. But California’s new breed of climate-change-fueled fires are burning hotter and faster than those of the past, sometimes slowing the regrowth process and even converting some areas from coniferous trees into grasslands, shrubs and chaparral, the researchers said.”

However a 2021 prior WUWT article addressed the fact that year 2020 wildfire emissions likely wiped out the state AB 32 emissions reductions and also addressed in detail the huge state government forest management failures that have contributed to the states wildfire growth and increasing risks over the past decade with these critical failures hidden from view in the Times article.  This prior WUWT article notes:

“California’s climate alarmists claim “climate change” is responsible for this wildfire outcome but an extensive 2018 California Legislative Analyst Office (LAO) report presents clear and compelling evidence demonstrating that decades of forest mismanagement by the state have in fact created the growing wildfire crisis.

The LAO report notes that increased fire risks are present throughout California driven by forest conditions that have been allowed by the state to develop for decades.”

Provided below are some of the highlights (or lowlights) of the state governments forest management failures that have led directly to increased wildfire growth and risks that have nothing to do with “climate change” as addressed in the states LAO analysis and presented in the prior WUWT article.

Typhoon Frequency Has Fallen Since 1950, Contradicting Alarmist Global Warming Claims

by P. Gosselin, Oct 18, 2022 in NoTricksZone

Charts by Kirye, using data from the Japan Meteorological Agency (JMA)

Extreme weather events, like tropical storms, are supposed to be intensifying and becoming more frequent as the world warms, the global warming alarmists like to claim as they try to spread panic and anxiety. This, they say, is robustly supported by science and so humanity is facing dire consequences unless it stops burning fossil fuels immediately.

Today let’s use the scientific data on Pacific typhoons to see if the alarmist claims are true. These data are provided by the renowned Japan Meteorological Agency (JMA). Surely typhoons must be increasing in frequency year by year since the temperature has risen over the 20th century.

First we look at the number of typhoons occurring in September, since 1951:

Hurricane Hype, Lies, Censorship – And Reality

by P. Driessen, Oct 10, 2022 in ClimateChangeDispatch

Hurricane Ian is in the history books, having unleashed its Category 4 fury on southwestern Florida.

Even as the area slowly digs out and rebuilds, the devastation and tragedies will linger in reality and memories.

Ian was the latest of 123 hurricanes to hit the Sunshine State since official recordkeeping began in 1851. But unsurprisingly, some wasted no time trying to link Ian to the most dominant issue of our time. [bold, links added]

Climate change is “rapidly fueling super hurricanes,” a Washington Post headline proclaimed.

“I grew up [in Florida] and these storms are intensifying,” CNN’s Don Lemon insisted.

Rising temperatures in the atmosphere and ocean are making hurricanes “stronger, slower and wetter,” reporter Morgan McFall-Johnsen asserted.

They’re becoming more frequent and intense, multiple commentators pronounced.

Ian should have “finally ended” the debate about “whether there’s climate change,” President Biden stated, as he assessed damage along Florida’s Gulf Coast with Governor and First Lady DeSantis.

The newest fearmongering is slightly more sophisticated. Now hurricanes are gaining strength more rapidly because of fossil fuels. The phenomenon even has a fancy name: “rapid intensification.”

This clever claim cannot be proven or disproven, because we didn’t have technologies to measure how rapidly certain storms intensified even a few decades ago.

The Media Are Deliberately Lying About Climate Change And Hurricanes

by M. Schellenberg, Oct 4, 2022 in ClimateChangeDispatch

Over the last several weeks, many mainstream news media outlets have claimed that hurricanes are becoming more expensive, more frequent, and more intense because of climate change. [bold, links added]

• The Financial Timesreported that “hurricane frequency is on the rise.”

• The New York Timesclaimed, “strong storms are becoming more common in the Atlantic Ocean.”

• The Washington Postsaid, “climate change is rapidly fueling super hurricanes.”

• ABC Newsdeclared, “Here’s how climate change intensifies hurricanes.”

• Both the FT and NY Times showed graphs purporting to show rising hurricane frequency using data from the U.S. government’s National Oceanic and Atmospheric Administration (NOAA).

All those claims are false.

The increasing cost of hurricane damage can be explained entirely by more people and more property in harm’s way. Consider how much more developed Miami Beach is today compared to a century ago. Once you adjust for rising wealth, there is no trend of increasing damage.

Claims that hurricanes are becoming more frequent are similarly wrong.

“After adjusting for a likely undercount of hurricanes in the pre-satellite era,” writes NOAA, “there is essentially no long-term trend in hurricane counts. The evidence for an upward trend is even weaker if we look at U.S. landfalling hurricanes, which even show a slight negative trend beginning from 1900 or from the late 1800s.”

What’s more, NOAA expects a 25% decline in hurricane frequency in the future.

Weather Disasters Wrongly Linked To Global Warming By Two International Agencies

by P. Homewood, Oct 4, 2022 in NotaLotofPeopleKnowThat

…

…

Because the data is compiled from the same EM-DAT da­tabase, the annual number of deaths shows an uptick from the 1990s to the 2000s. It is clear though that disaster-related deaths from extreme weather have been falling since the 1920s and are now approaching zero. This is due as much to improved planning, more robust structures and early warning systems, as it is to diminishing numbers of natural disasters. And, as can be seen from the figure, it is earthquakes – entirely natural events – that have been the deadliest disasters over the last two decades.

Ignoring all the evidence, however, the press release accompanying the latest WMO report proclaims that “Climate science is clear: we are heading in the wrong direction,” the UN Secretary-General adding, with characteristic hype, that the report “shows climate impacts heading into uncharted territory of destruction.”

A more detailed discussion of the erroneous claims of both CRED and the WMO can be found in my two most recent reports on weather extremes (here and here).

Good News: 2022 Hurricane Season Mild. Bad News: Pressure Pattern Threatens Europe with Hell Winter

This year’s hurricane season has been unusually quiet. The USA has gotten off easy so far in terms of landfalls and damage, thus once again contradicting all the doomsday scenarios from the climate alarmists.

Mid September is usually the peak of hurricane activity. But right now it’s quiet and there are no threats to the US mainland – for the time being. Here’s the latest update from the National Hurricane Center (NHC):

Potential killer winter on top of acute energy crisis

On another subject, some forecasters have been projecting a milder than normal winter for Europe, which would be welcome with a red carpet due to the continent’s acute energy crisis.

However, Joe notes there are signs this may not be the case. That would mean the coming winter could become – in the current dire energy situation – the Mother of Nightmares: a bitter cold winter with energy outages. In the event of blackouts, which many experts warn have a high chance of occurring, Europe would then be facing a humanitarian and economic crisis on a scale not seen in a very long time.

“Look at what the surface maps are showing,” Bastardi says. “When you have high pressure over Greenland and Iceland, and low pressure over Spain like that, folks, that is an ugly looking situation for the winter. That is similar to 2010/11.”

Climate Emergency Not Supported by Data, Say Four Leading Italian Scientists

by C. Morrison, Sep 14, 2022 in DailySkeptic

Four leading Italian scientists have undertaken a major review of historical climate trends and concluded that declaring a ‘climate emergency’ is not supported by the data. Reviewing data from a wide range of weather phenomena, they say a ‘climate crisis’ of the kind people are becoming alarmed about “is not evident yet”. The scientists suggest that rather than burdening our children with anxiety about climate change, we should encourage them to think about issues like energy, food and health, and the challenges in each area, with a more “objective and constructive spirit” and not waste limited resources on “costly and ineffective solutions”.

During the course of their work, the scientists found that rainfall intensity and frequency is stationary in many parts of the world. Tropical hurricanes and cyclones show little change over the long term, and the same is true of U.S. tornadoes. Other meteorological categories including natural disasters, floods, droughts and ecosystem productivity show no “clear positive trend of extreme events”. Regarding ecosystems, the scientists note a considerable “greening” of global plant biomass in recent decades caused by higher levels of carbon dioxide in the atmosphere. Satellite data show “greening” trends over most of the planet, increasing food yields and pushing back deserts.

The four scientists are all highly qualified and include physics adjunct professor Gianluca Alimonti, agrometeorologist Luigi Mariani and physics professors Franco Prodi and Renato Angelo Ricci. The last two are signatories to the rapidly growing ‘World Climate Declaration’. This petition states that there is no climate emergency and calls for climate science to be more scientific. It also calls for liberation from the “naïve belief in immature climate models”. In future, it says, “climate research must give significantly more emphasis to empirical science”.

Nothing Alarming: Europe Data Show No Upward Trend In Droughts And Forest Fires

by P. Gosselin, Aug 24, 2022 in NoTricksZone

German online NOVO-Argumente looks at the forest fire situation in Germany and Europe.

Currently parts of Europe are experiencing severe drought conditions and forest fires are raging in Germany. Climate activists and the mainstream are claiming it’s climate change, and it’s unprecedented.

But NOVO-Argumente looks at the historical data going back decades and finds nothing alarming.

Over the long-term average (1993 to 2019), 1035 forest fires in Germany were recorded with an average of 656 hectares affected. The amount of damage is just 1.38 million euros. Forest fires therefore cost us about as much per year as we spend every 30 minutes on subsidizing solar and wind energy.

“No evidence of an increase in forest fires”

As the following graph shows, there is no evidence of an increase in forest fires over the last 30 years in terms of number and extent. The peaks are not seen in this chart from the Federal Environmental Agency because they are in the past. In 1975, over 8000 hectares burned in Lower Saxony alone. In contrast, in the year 2021, which is not yet recorded in the graph, there were only 548 forest fires in the whole of Germany on a total area of 148 hectares.

Welfare in the 21st century: Increasing development, reducing inequality, the impact of climate change, and the cost of climate policies

by B. Lomborg, July 2020 in TechForecSocChange

Abstract

Climate change is real and its impacts are mostly negative, but common portrayals of devastation are unfounded. Scenarios set out under the UN Climate Panel (IPCC) show human welfare will likely increase to 450% of today’s welfare over the 21st century. Climate damages will reduce this welfare increase to 434%.

Arguments for devastation typically claim that extreme weather (like droughts, floods, wildfires, and hurricanes) is already worsening because of climate change. This is mostly misleading and inconsistent with the IPCC literature. For instance, the IPCC finds no trend for global hurricane frequency and has low confidence in attribution of changes to human activity, while the US has not seen an increase in landfalling hurricanes since 1900. Global death risk from extreme weather has declined 99% over 100 years and global costs have declined 26% over the last 28 years.

Arguments for devastation typically ignore adaptation, which will reduce vulnerability dramatically. While climate research suggests that fewer but stronger future hurricanes will increase damages, this effect will be countered by richer and more resilient societies. Global cost of hurricanes will likely decline from 0.04% of GDP today to 0.02% in 2100.

Climate-economic research shows that the total cost from untreated climate change is negative but moderate, likely equivalent to a 3.6% reduction in total GDP.

Climate Expert: What The Media Won’t Tell You About Droughts

by R. Pileke Jr, Aug 16, 2022 in ClimateChangeDispatch

Europe is in the midst of what has been called the worst drought in 500 years. According to a drought expert with the European Commission in comments last week [bold, links added]:

“We haven’t analysed fully the event (this year’s drought), because it is still ongoing, but based on my experience I think that this is perhaps even more extreme than 2018. Just to give you an idea the 2018 drought was so extreme that, looking back at least the last 500 years, there were no other events similar to the drought of 2018, but this year I think it is really worse than 2018.”

While a full analysis of the ongoing 2022 European drought remains to be completed, so too the drought itself, which is clearly exceptional if not unprecedented. In this post, I take a close look at the state of understanding of the possible role of climate change in this year’s drought.

Specifically, I report on what the most recent assessment report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) and underlying literature and data say about the detection of trends in Western and Central European drought and the attribution of those trends to greenhouse gas emissions.

The figure below shows the specific region that is the focus of this post, which includes all of Germany, most of France, Hungary, Poland, Ukraine, and western Russia among other nations. …

Europe wildfires: Are they linked to climate change?–NO!!!

by P. Homewood, Aug 15, 2022 in NotaLotofPeopleKnowThat

The BBC would like you to think so, with statements like these:

So far this year, the amount of land burnt by fires across the European Union is more than three times greater than what you would expect by the middle of July.

Almost 346,000 hectares (1,370 sq miles) of land have been recorded as burnt (as of 16 July), according to the European Forest Fire Information System (EFFIS).

Much of Western Europe has been hit by a record-breaking heatwave, which substantially increases the risk of fires….

“Heatwaves and droughts are exacerbated by climate change and are absolutely the defining factor in years with massive wildfire outbreaks, like the present one,” Dr Jones says….

“But we definitely see trends in fire weather risk because of climate change.

“The risk is higher in the Mediterranean region than the rest of Europe.”

Studies show increasing fire risk for central and southern regions of Europe over the past couple of decades.

Yet tucked away in the same article is this graph which proves all of these have no basis in fact:
