Venice canals almost run dry just two months after flooding

Low tide in Venice

This so-called man-made climate change thing must be a versatile beast, if it exists outside of myths. Wednesday’s rare super blue blood moon gets some of the blame here, but recent low rainfall also played a part.

Although the water levels in the city’s famous canals rise and fall with the tide, exceptionally low tides have left canals bare, reports Sky News.

Two months ago the high tide in Venice peaked at 187cm (6.14ft), leaving around 70% of the lagoon city centre under salt water.

Australian Bushfires Much Worse In 1974/5

.

Note to climate doomers: weather can, and does, vary without assistance from humans.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

An important and, as usual, forensic contribution from Roy Spencer:

Summary Points

1) Global wildfire activity has decreased in recent decades, making any localized increase (or decrease) in wildfire activity difficult to attribute to ‘global climate change’.

2) Like California, Australia is prone to bushfires every year during the dry season. Ample fuel and dry weather exists for devastating fires each year, even without excessive heat or drought, as illustrated by the record number of hectares burned (over 100 million) during 1974-75 when above-average precipitation and below-average temperatures existed.

3) Australian average temperatures in 2019 were well above what global warming theory can explain, illustrating the importance of natural year-to-year variability in weather patterns (e.g. drought and excessively high temperatures).

4) Australia precipitation was at a record low in 2019, but climate models predict no long-term trend in Australia precipitation, while the observed trend has been upward…

Claim: newly identified jet-stream pattern could imperil global food supplies

Another day, another attempt at a climate scare story. That’s a well-identified pattern too. But is this jet-stream pattern really ‘newly’ identified, or was it described by NASA nine years ago? Meteorology uses the term omega block. Which side of the block a region is on determines whether it’s warmer or colder than normal for the duration.

Scientists have identified systematic meanders in the globe-circling northern jet stream that have caused simultaneous crop-damaging heat waves in widely separated breadbasket regions-a previously unquantified threat to global food production that, they say, could worsen with global warming.

The research shows that certain kinds of waves in the atmospheric circulation can become amplified and then lock in place for extended periods, triggering the concurrent heat waves, reports Phys.org.

Affected parts of North America, Europe and Asia together produce a quarter of the world food supply. The study appears this week in the journal Nature Climate Change.

Saturn’s moon Titan may help decode climate change on Earth: Study

View from Titan [artist’s impression]

From the report: ‘the researchers said, learning more about the energy budget of Titan can add to the understanding of climate change on Earth.’ Indeed – and help could be at hand with that.

Researchers have found that Saturn’s largest moon Titan undergoes significant seasonal changes in its energy budget — the amount of solar energy it absorbs, and the heat it emits — an advance that may lead to new insights about climate fluctuations on the Earth, reports Financial Express.

The study, published in the journal Geophysical Research Letters, noted that Titan is the only body in the solar system, other than Earth, with a significant atmosphere and liquid surface lakes.

The researchers, including those from the University of Houston in the US, said Titan’s dynamically-varying energy budget has important impacts on its weather and climate systems.

Study Shows Electric Cars Become Practically Useless In Cold Weather

EVs are looking like yet another ‘save the planet’ fiasco in the making. Some of the points made here were already known, but these studies reinforce them. As many EVs on the road are still relatively new, the full extent of any problems may not yet be clear. With the help of large subsidies and other incentives they sell well in Norway despite the cold winters there.

According to recent studies, cold temperatures significantly reduce the performance of electric cars, especially when it comes to battery life.

One study by AAA suggested that cold temperatures can reduce the range of the batteries in most electric cars by over 40 percent, reports Anonymous News.

It was also noted that the performance can be even worse when the interior heaters are used.

Indo-Pacific Ocean warming is changing global rainfall patterns, say researchers

It’s ‘according to a new study’ time again, as the Madden-Julian Oscillation (MJO) goes under the microscope. Another causes and effects puzzle.

New research by NOAA and a visiting scientist from India shows that warming of the Indo-Pacific Ocean is altering rainfall patterns from the tropics to the United States, contributing to declines in rainfall on the United States west and east coasts, reports Phys.org.

In a study published this week in the journal Nature, researchers report a doubling in the size of a warm pool of water spanning the western Pacific and eastern Indian Ocean in recent years.

This Indo-Pacific warm pool in what is already the warmest part of the global ocean is expanding each year by an area the size of California.

‘Stay put,’ officials warn: Winter storms slam US as 50 million people travel for Thanksgiving

One minor problem with that Yahoo News headline – it isn’t even winter yet.

Two powerful winter storms hammered the West Coast and Midwest on Wednesday, shutting down highways and snarling travel plans on one of the nation’s busiest travel days.

Weather watches, warnings and alerts were posted across much of the western half of the nation after a storm that had been a “bomb cyclone” marched westward from the California coast, AccuWeather reported.

Hundreds of stranded cars were removed from Interstate 5 headed north from California into Oregon in the aftermath of the storm that dumped snow and created whiteout conditions on both sides of the California-Oregon border.

The 2019 North Atlantic hurricane season ends officially later this week. Here I am going to give you the straight scoop on hurricanes.

Everything that follows is fully consistent with recent scientific assessments of the Intergovernmental Panel on Climate Change, U.S. National Climate Assessment and World Meteorological Organization.

In fact, the information below comes straight out of these authoritative assessment reports.

Chris Martz: No, global warming is not causing more frequent Arctic outbreaks

By what known physics could a few molecules of carbon dioxide upset the jet stream? A meteorologist is not impressed by such claims.

By Chris Martz | November 9, 2019
INTRODUCTION Just when wildfires weren’t enough, we now have people blaming cold weather on a warming climate, which seems quite contradictory.

In light of the Arctic outbreak in forecast this coming week, people like Phil Plait (who has since blocked me) took to Twitter (Figure 1) to claim that man-made climate change is causing frigid, Arctic air to be displaced south into the United States, Europe, and Asia.

His argument, which is supported by some climate scientists, suggests that man-made global warming causes the polar jet stream to destabilize causing it to become wavy rather than zonal, sending Arctic air southward into the mid-latitude regions.

He also stated that without global warming, the polar air would stay near the north pole.

Both of these claims are exactly backwards from reality and are not supported by weather dynamics, the global warming theory, or statistical observations in long-term temperature data.

Electric-Car Owners Hard Hit by Massive California Power Shutdown

From Car and Driver

— Nearly a million Californians are now without power as the electric company deliberately shut it off this week, fearing high winds would spark wildfire.

— The affected area in Northern California surrounds Fremont, home of Tesla, and a great many electric-car owners who can’t charge their vehicles as usual.

Scientists predict average late winter precipitation in western Europe for the next decade

We like to see a few bold predictions here at the Talkshop, even if they expect things to be ‘average’, but as these go out to ten years ahead we’ll add them to the (imaginary) list. The current very low solar minimum could be a wild card.

In a new study, scientists at the National Center for Atmospheric Research (NCAR) show that the average March precipitation, over the next ten years in western Europe is predictable using a novel method, says Phys.org.

The research team also issued a forecast for the coming years.

Spring ozone hole may be one of the smallest for decades

Southern hemisphere spring, that is.

European weather scientists believe the ozone hole over the Antarctic this spring may be one of the smallest since the mid-1980s, says stuff(NZ).

Experts at the Copernicus Atmosphere Monitoring Service (CAMS) have observed strange behaviours of the annual ozone hole this season.

Not only is it already shrinking and well on the way to being about half the size it usually is at this time of year, but also it began forming about two weeks earlier than usual and it is off-centre, away from the South Pole.

They say that is probably the result of the rare sudden stratospheric warming, which has been under way about 30km above Antarctica since last month.

Lightning ‘superbolts’ form over oceans from November to February

Image credit: NASA

But why so? ‘No theories so far’ seems to be the real meaning behind the quote ‘for reasons that are not yet fully understood’. One of the few clues is that such strikes tend to be over water, and mainly in specific areas e.g. the Mediterranean.

The lightning season in the Southeastern U.S. is almost finished for this year, but the peak season for the most powerful strokes of lightning won’t begin until November, according to a newly published global survey of these rare events.

A University of Washington study maps the location and timing of “superbolts”—bolts that release electrical energy of more than 1 million Joules, or a thousand times more energy than the average lightning bolt, in the very low frequency range in which lightning is most active, reports Phys.org.

Results show that superbolts tend to hit the Earth in a fundamentally different pattern from regular lightning, for reasons that are not yet fully understood.

Hurricane Dorian: Just weather, not climate change

Hurricane Dorian

As the peak of the Atlantic hurricane season arrives, weather forecaster Chris Martz tries to inject some sanity into the clamour around the latest weather event to hit the headlines. This is an extract from the full article, which as you might expect offers a more in-depth view.

We’ve made it three weeks without extreme weather and/or climate change hysteria making rounds on social media. Unfortunately, that streak has come to an end, making the lives of most weather forecasters like me a lot more difficult.

We are quickly approaching climatological peak of the Atlantic hurricane season¹ (September 10th) (Figure 1), thus it should be NO surprise to anyone that we have seen an uptick in tropical activity. However, I stand corrected － people are losing their minds about it.

Debunking the SST myth

I want to debunk the popular myth that has been circulating around the internet. Warmer sea surface temperatures (SST) does not guarantee that hurricanes will become more frequent or more intense.

Dorian becomes a Category 4 monster powering toward Florida

UPDATE 1st Sept.: Dorian is now reported to be a Category 5 storm as it strikes the Bahamas.

After an unusually quiet start to the Atlantic hurricane season, things have suddenly become serious. Uncertainty abounds but this could become ugly for south-eastern USA, Florida in particular. This report says ‘there were fears it could prove to be the most powerful hurricane to hit Florida’s east coast in nearly 30 years.’ Or it might not hit at all – at this stage, nobody knows.

Hurricane Dorian powered toward Florida with increasing fury Friday, becoming an “extremely dangerous” Category 4 storm but leaving forecasters uncertain whether it would make a direct hit on the state’s east coast or inflict a glancing blow, reports Phys.org.

The storm’s winds rose to 130 mph (215 kph) and then, hours later, to a howling 140 mph (225 kph) as Dorian gained strength while crossing warm Atlantic waters.

The hurricane could wallop the state with even higher winds and torrential rains late Monday or early Tuesday, with millions of people in the crosshairs, along with Walt Disney World and President Donald Trump’s Mar-a-Lago resort.

UK weather latest: Downpours set to last ‘until end of August’

Credit: BBC

What happened to the ‘unprecedented’, ‘new normal’ hot weather that blew in from north Africa for a few days, then blew away again? Or was that just the media and warmist climate pundits shooting the breeze for yet another opportunistic headline? In any case it looks as if the Great British Summer is now back to its usual erratic self, but becoming somewhat wetter than the seasonal average.

Thunderstorms and heavy downpours are set to hit the UK this week, as Brits face what could be one of the wettest Augusts on record, says the Evening Standard.

Severe thunderstorm warnings are in place for London and the south east on Monday, with the chance of flooding, travel disruption and power cuts, the Met Office warns.

Putting a Cap on Heat Hysteria

Forecaster Joe Bastardi attempts to cool some fevered brows with a more rational view of recent weather.

Joe Bastardi  ~   

It’s summer, it’s hot, and the climate-change agenda is turning up the heat on the weaponization of weather. So I thought some perspective may be in order.

No question the last three Julys have been warmer than average for a large area of the nation.

But for perspective, the three Julys before that were quite cool in the U.S.

The 2015-16 Super El Niño, with its input of massive amounts of water vapor, changed all that. How can we tell it’s water vapor and not CO2? Because nighttime lows (mins) are beating out daytime highs (maxes) in relation to averages. The moisture in the air when the air is stable at night effectively keeps temperatures up (as do Urban Heat Islands). However, because there is not enough corresponding warming aloft, more clouds form during the day from convective processes as it heats up…

More Failed Predictions: May Was The Second Wettest Month In US History

Credit: weather.com

H/T Climate Change Dispatch

An obvious clue in this report is the mention of the jetstream, which is not known to be related to minor trace gases in the atmosphere, despite wishful thinking in some quarters. Why do leaders ignore these failures of climate science, yet listen avidly to misguided doomsayers demanding vast spending and taxes?
– – –
National Oceanic and Atmospheric Administration reported the month of May was the second wettest and temperatures were in the bottom-third for its 125-year US history, reports American Thinker.

The 2010 publication titled, ‘A Global Overview Of Drought and Heat-Induced Tree Mortality Reveals Emerging Climate Change Risks for Forests’, was accepted by the Obama administration as scientific evidence that climate change had made the Earth:

“…increasingly vulnerable to higher background tree mortality rates and die-off in response to future warming and drought, even in environments that are not normally considered water-limited.”

But NOAA just reported that May US precipitation totaled an average of 4.41 inches, 1.50 inches above average, and ranked second wettest in the 125-year period of record for May as well as second wettest for all months since January 1895.

The only wetter month in US history was May 2015 with 4.44 inches of precipitation.
