Not what some might have imagined perhaps. Researchers found that temperature difference between the surface and the liquid was less important than ‘the difference in pressure between the liquid surface and the ambient vapor’.

For the first time, MIT scientists have analyzed the evaporation process in detail at a molecular level and determined the physics of evaporation, reports Tech Explorist.

Evaporation is the process by which water changes from a liquid to a gas or vapor. The process is the primary path for water to move from the liquid state back to the water cycle as atmospheric water vapor.

Evaporation commonly occurs in everyday life. When you get out of the shower, the water on your body evaporates as you dry. If you leave a glass of water out, the water level will slowly decrease as the water evaporates.

For the first time, MIT scientists have analyzed the evaporation process in detail at a molecular level. For this, they used a new technique to control and detect temperatures at the surface of an evaporating liquid. Doing this, they were able to identify a set of universal characteristics involving time, pressure and temperature changes that determine the details of the evaporation process.

Queensland, Australia


Sub-tropical snow – some folk may have to manage without electricity from their solar panels until it goes 😎

Icy conditions are sweeping across eastern Australia, bringing snow to areas as far north as sub-tropical Queensland in what is believed to be the heaviest snowfall in years, reports the Evening Standard.

Australia’s Bureau of Meteorology described the weather as “rare” adding that Queensland had not experienced significant snowfall since 2015.

June marks the beginning of winter in Australia but the extreme weather is highly unusual, especially so early on in some areas of Tasmania, Victoria, Queensland and New South Wales.

Many took to social media to express their amazement at finding snow in their hometowns as well as sharing photos of Kangaroos and Tasmanian devils playing in the cold conditions.

The Blue Mountains west of Sydney woke on Tuesday to a blanket of snow, while there have been falls in Queensland’s Granite Belt region, west of Brisbane, although snow was not expected to settle.

Travellers are also being warned to expect delays on roads, rail, waterways and in the skies amid a day of wild weather and icy winds.

‘The coronal heating problem in solar physics relates to the question of why the temperature of the Sun’s corona is millions of kelvins higher than that of the surface. Several theories have been proposed to explain this phenomenon but it is still challenging to determine which of these is correct’ — Wikipedia.

It’s one of the greatest and longest-running mysteries surrounding, quite literally, our sun—why is its outer atmosphere hotter than its fiery surface?

University of Michigan researchers believe they have the answer, and hope to prove it with help from NASA’s Parker Solar Probe, says Phys.org.

In roughly two years, the probe will be the first manmade craft to enter the zone surrounding the sun where heating looks fundamentally different than what has previously been seen in space.

This will allow them to test their theory that the heating is due to small magnetic waves travelling back and forth within the zone.

New study published by Springer today makes interesting reading. Phil Jones’ ears will be burning brightly.

Abstract:
Historical temperature records are often partially biased by the urban heat island (UHI) effect. However, the exact magnitude of these biases is an ongoing, controversial scientific question, especially in regions like China where urbanization has greatly increased in recent decades. Previous studies have mainly used statistical information and selected static population targets, or urban areas in a particular year, to classify urban-rural stations and estimate the influence of urbanization on observed warming trends. However, there is a lack of consideration for the dynamic processes of urbanization. The Beijing-Tianjin-Hebei (BTH), Yangtze River Delta (YRD), and Pearl River Delta (PRD) are three major urban agglomerations in China which were selected to investigate the spatiotemporal heterogeneity of urban expansion effects on observed warming trends in this study. Based on remote sensing (RS) data, urban area expansion processes were taken into consideration and the relationship between urban expansion rates and warming trends was investigated using data from 975 meteorological stations throughout China.

Is climate alarm propaganda worse than we thought?

PA Pundits - International

From the team at CFACT ~

Newly published data gathered by NASA’s AIRS satellite confirm the Earth is warming more slowly than has been forecast by climate activists and the United Nations Intergovernmental Panel on Climate Change (IPCC). Data gathered from 2003 through 2017 confirm temperatures remained essentially flat from 2003 through 2015, finally rising briefly as a strong El Nino formed in 2015 and lasted into 2016 (https://ggweather.com/enso/oni.htm). Even with El Nino adding an illusory warming spike at the end of the period, temperatures still rose just over 0.2 degrees during the 15-year period. That pace works out to less than 1.5 degrees of warming per century.

IPCC initial forecasts called for 0.3 degrees Celsius of warming per decade, while skeptic forecasts have tended to hover around 0.1 degrees. As temperatures warmed more slowly than IPCC predicted, IPCC reduced its forecasts to meet skeptics in the middle…

Omega blocking highs can remain in place for several days or even weeks [image credit: UK Met Office]


Atmospheric blocking is a well-known weather phenomenon. The report below says ‘In recent years, the scientists observed a clear increase of these patterns’. But scientists have also reported a 20 year decline in solar magnetic fields and solar wind micro-turbulence levels. Coincidence, or possibly not?

Record breaking heatwaves and droughts in North America and Western Europe, torrential rainfalls and floods in South-East Europe and Japan – the summer of 2018 brought a series of extreme weather events that occurred almost simultaneously around the Northern Hemisphere in June and July, says IOP Publishing.

These extremes had something in common, a new study published today in Environmental Research Letters by an international team of climate researchers now finds.

The events were connected by a newly-identified pattern of the jet stream encircling the Earth. The jet stream formed a stalled wave pattern in the atmosphere, which made weather conditions more persistent and thus extreme in the affected regions.

The same pattern also occurred during European heat waves in 2015, 2006 and 2003, which rank among the most extreme heatwaves ever recorded. In recent years, the scientists observed a clear increase of these patterns.

An Impression of Winter by Claude Monet


Is the Earth still recovering from the Little Ice Age, a time when many glaciers advanced and recorded sea levels were falling?

The Little Ice Age was a period from about 1300 to 1870 when Europe and North America experienced much colder winters than we do today, says 5 Minute History.

Paintings from the Little Ice Age show us what it was like.

Climate Hearsay

As the forces of climate alarm degenerate ever further into synthetic hysteria and absurdity, Ross McKitrick tries to restore some perspective.

Science Matters

In a legal proceeding, a witness can only testify to what he or she personally experienced. Anything reported to them by others is dismissed as “hearsay”, not evidence by direct observation, but rather an opinion offered by someone else.

In the current public commotion over global warming, almost all the discourse is composed of hearsay.  Ross McKitrick explains that the alleged changes in temperatures are so small that no one can possibly notice. Thus, their concern over global warming can only come from repeating hearsay in the form of charts and graphs published by people with an axe to grind. His article in the Financial Post is Hold the panic: Canada just warmed 1.7 degrees and … thrived. Excerpts below in italics with my bolds.

A recent report, commissioned by Environment and Climate Change Canada (also known as the federal Department of the Environment), sparked a feverish bout of…

If the global warming nightmare was to happen, solar and wind systems simply don’t work in high-heat environments. So why are activists pushing them, asks Climate Change Dispatch?

Everything, and I mean everything about the man-made global warming movement is rotten to the core, says Dr. Joel Adams.

Tens of thousands of our own brave and brilliant scientists, as well as websites such as Climate Change Dispatch, are fighting the good fight against the climate change fraud every day. It’s a fight we are working hard to win.

I just completed a 435-page book on the subject of climate change fraud and the people and motivations behind it.

I discovered that as bad as the scientific fraud is, the motivations behind it turned out to be worse. These motivations are to put it in a few words: money and a political totalitarian power grab by the political Left.

Plenty of assertions, but we’re still no nearer to knowing ‘what fraction of the observed rise in global surface temperature over the last thirty or so years…is attributable to the human-induced increase in atmospheric carbon dioxide’. It could be anything, including nothing. We don’t even have a CO2 number to work with, as any natural increases are hard to quantify. But in many countries national energy policy ploughs on regardless of the huge uncertainties.

The bottom line of politically correct thought on climate alarm is so full of holes that it brings the overall sanity of mankind into question, argues Garth Paltridge.

That is, we need to put a dollar number to the cost of doing something now, a dollar number to the benefit thus obtained by the future generations, and a number to a thing called “discount for the future”—this last being the rate at which our concern for the welfare of future generations falls away as we look further and further ahead.

Only the first of these numbers can be estimated with any degree of reliability.

Global warming – more tortoise than hare? [image credit: hevria.com]

Once again the forces of climate fear are sounding the alarm bells, but is there anything new to justify it? A new report thinks not.
H/T Climate Change Dispatch

Contrary to claims by the WMO that global warming and its impacts are speeding up, data shows that since 2016, global temps have continued to decline, says Dr. Benny Peiser @ The GWPF .

The World Meteorological Organisation (WMO) is misleading the public by suggesting that global warming and its impacts are accelerating.

In fact, since 2016 global average temperature has continued to decline.

Showing once again that significant warming and cooling are normal features of the global climate over thousands of years and longer. We could speculate whether this particular research might be linked to the de Vries cycle.

The warm waters of the Gulf Stream flow up along the east coast of North America, moderating the climate of vast areas of northern and western Europe, says Phys.org.

Once the Gulf Stream gets far enough north, the warm waters cool.

As they cool, they sink and start flowing south, forming what scientists call the North Atlantic Deep Water.

Nick Balascio explained that the Gulf Stream/Deep Water system is known as the AMOC, or Atlantic Meridional Overturning Circulation.

Jakobshavn glacier, West Greenland [image credit: Wikipedia]


Without jumping to hasty conclusions, this is an interesting development not predicted by the IPCC’s supposed experts. Natural ocean/climate oscillations are implicated. Against assumptions, rising carbon dioxide levels cannot explain these latest observations.

A new NASA study finds a major Greenland glacier that was one of the fastest shrinking ice and snow masses on Earth is growing again, reports The GWPF.

The scientists were so shocked to find the change, Khazendar said: “At first we didn’t believe it.

“We had pretty much assumed that Jakobshavn would just keep going on as it had over the last 20 years.”

Do we have a climate problem or a bad science problem? The author argues for the latter.

Perhaps the worst aspect of the “Green New Deal” (GND) recently proposed by Representative Alexandria Ocasio-Cortez and Senator Edward Markey is that the authors have lost (or possibly never had) all perspective on climate change, writes Alan Carlin.

They are acting as if climate change were as bad a problem as the Great Depression, and that another “New Deal” is required for the US to survive.

This shows that they they really have no understanding of climate change and that Congress should never appropriate any funds for the purposes proposed by the GNDers.

Dr Roy Spencer tries to strike a note of sanity amidst the latest bout of doom-laden climate hysteria doing the rounds via cynical manipulation of the minds of school kids. What is accelerating is the bluster of alarmists, who lack credible empirical evidence of ‘human-caused’ as opposed to natural climate variation.

On March 5, 58 senior military and national security leaders sent a letter to President Trump denouncing his plan to form a National Security Council panel to take a critical look at the science underpinning climate change claims.

Their objections to such a Red Team effort were basically that the “science is settled”, writes Roy Spencer in The Washington Times.

But if the science is settled, what are they afraid of? Wouldn’t a review of the science come to the same conclusion as the supposed consensus of climate scientists?

This is a critique by Professor Nils-Axel Mörner and two colleagues of a recent article discussing problems with IPCC sea level claims.

The original article by Ken Haapala, President, Science and Environmental Policy Project (SEPP) starts:

Rising Seas – At Sea, or Shore? The latest Summary for Policymakers of its full Assessment Report by the UN Intergovernmental Panel for Climate Change (IPCC, AR-5, SPM, 2014) declared that sea level rise is accelerating.

Numerous studies have come out in support of that view. As shown in the 2008 report of the Nongovernment International Panel for Climate Change (NIPCC, 2008), with the ending of the last Ice Age about 18,000 to 20,000 years ago, sea levels have risen about 400 feet (120 meters).

At first, the rise was slow, then rapid, then for the past several thousand years slowing to about 7 to 8 inches (18 to 20 cm) per century. There is some question about the variation during the Little Ice Age and the period following it called the industrial period since 1850.

Climate models can’t be wrong or unreliable – can they? Except they generally are.

Academics from the School of Art & Design have teamed up with colleagues from the ANU Climate Change Institute on a design project, which takes existing data and communicates the impacts of climate change in a way that people can engage with and better understand, says Phys.org.

The resulting new climate tool visualises data which shows by 2050, Australians will no longer enjoy winter as they know it today and will experience a new season the designers are calling “New Summer”.

Unfortunately the IPCC shows little interest in perspective, preferring to trumpet absurd 8.5°C warming scenarios.

PA Pundits - International

Joe Bastardi  ~   

I went to school with a lot of great forecasters. One of them was Scott Chesner, who is an on-air meteorologist in Tyler, Texas. Scott tweeted something this week that I thought was quite profound regarding the current generation’s “consensus” on climate:

“One problem with global warming hysteria is ‘perspective.’ The warmer global temps of recent yrs. are relatively meaningless as we only have detailed records for~200 yrs. out of the Earth’s age of 4.5 billion yrs. That=30 sec. out of a person’s 80 yr. life!”

As you know, I am a big satellite-era proponent as far as temperatures are concerned. We have simply seen too much adjustment to older temperature records, and that has to at least raise questions. In almost every single case, temperatures are adjusted down in years before the satellite era.

This has some merit, given most errors on thermometers…

This report more or less answers its own question, possibly without noticing that the answer given virtually rules out the presence of any particular trace gases in the atmosphere as a likely cause. ‘Hottest on record’ does not go back all that far anyway.

As western Europe enjoys record highs for winter temperatures, southern parts of the continent are being hit with snow flurries, reports Phys.org.

What is going on with the weather, and how closely are the topsy-turvy temperatures linked to climate change?

As the ‘official’ (IPCC, Met Office etc.) view insists that more warming lies ahead, other analysts foresee significant cooling. Clearly, somebody has to be wrong.

The Next Grand Minimum

Definition — cusp: a point of transition between two different states

The transition from the Medieval Warm Period and the Little Ice Age was punctuated by extreme climate events, intense storms, floods, and droughts according to Lynn Ingram and Francis Malamud-Roam writing in The West Without Water. According to the authors, the transition from the Little Ice Age to the Modern Warm Period also experienced erratic weather extremes. Wolfgang Behringer, writing in the Cultural History of Climate, found similar transitions to more extreme weather. These extreme record-setting events are a signal that the overall climate is moving to a different state, in other words on the cusp of climate change.

Some recent record events:

Japan’s northern island of Hokkaido: Record cold temperatures, minus 24.4 C, the lowest seen since it began compiling such data in 1957.

Seattle: Coldest February in 30 years, the 4th coldest in 75 years, the…
