Hurricane threat to East Coast due to natural factors
First at his most recent Saturday Summary, the 40-year meteorologist first warns that in-close developing hurricanes of the sort seen in the 1930s are a risk to the US East Coast this year, due the current Atlantic temperature pattern. The reason has nothing to do with CO2 in the atmosphere, but because of natural sea surface temperature cycles.
Sea surface temperatures see “pretty dramatic turnaround”
The ‘average’ world temperature for June 2018 was +0.21 deg C above the 1981 – 2010 mean. That represented a decline of about 0.65 deg C from the all-time high of this 39-year record, which was reached in early 2016. The 0.65 deg C decline represented more than 75% of the amount by which the average temperature had exceeded the 1981 – 2010 mean at the highest point. Suddenly the fact that some large number of “all-time highs” was being set at the end of June does not seem very significant.”
A University of Aizu team has identified two distinct Indo-Pacific processes shaping the unique features and extraordinary ferocity of super El Ninos. A systematic analysis of these processes and their interactions will improve forecasts of the elusive super El Ninos, the researchers claim.
…
Extremely warm sea surface temperatures are a notable feature of the super El Ninos that occurred in 1972, 1982, and 1997. The fact that Pacific Ocean processes responsible for generating regular El Ninos could not explain this key signature of super El Ninos came as a big shock,” says Dachao Jin, co-author of the study.
If you were to believe the mainstream media, you’d think our world is burning up. But that is not true.
Yes, there were places on our planet where it was warmer than normal today. But many parts of the world displayed normal or even colder than normal temperatures.
According to the report, if we are to take cooling demand seriously, the key stages to move towards a solution for cooling demand are:
Reducing the energy required for cooling: getting industry to adopt high efficiency cooling technologies and using maintenance to deliver optimum performance.
Reducing the need for cooling through better building design
Systems level thinking across built environment and transport
Considering the strategies and skills required for installing appliances and maintaining them in order to maximise efficiency and reduce energy demand
Creating a model for delivery of affordable cooling to those in rural and urban communities based on the energy needs of local requirements, rather than imposing a ‘one size fits all’ approach
How have we measured the temperature of the ocean’s upper layer in the last 150 years? How does understanding physical processes and observational errors help to standardise climate data and understand climate change?
Sea surface temperature (SST) is also one of the climate indices with the longest histories of direct measurements. Because ocean makes up about 70% of the total Earth’s surface, changes in the temperature of its surface are a key factor for determining the global temperature of the planet’s surface.
Summers in the U.S. are hot. They always have been. Some are hotter than others.
Speaking as a PhD meteorologist with 40 years experience, this week’s heat wave is nothing special.
But judging from the memo released on June 22 by Public Citizen (a $17 million per year liberal/progressive consumer rights advocacy grouporiginally formed by Ralph Nader in 1971 and heavily funded by Leftwing billionaire George Soros’s Open Society Foundations), every heat wave must now be viewed as a reminder of human-caused climate change. The memo opines that (believe it or not) the news media have not been very good about linking weather events to climate change, which is leading to complacency among the public.
With those hot weather records in Los Angeles being set, it’s important to remember where measurements are taken. I’ve done an investigation and found that every “all time high” reported by the LA Times is from a station compromised by heat sources and heat sinks. In my opinion, the data from these stations is worthless.
It’s been going on for some time, for example, back in 2010, because there’s been a questionable high reading reading at USC of 113°F.
German climate and weather analyst “Schneefan” (Snow Fan) here writes a summary of the first half of 2018 thus far. All data show that the surface temperature of the globe has been cooling strongly over the past months and polar ice mass growing.
He writes that in the first half of this year we have seen weak solar activity and La Nina conditions acting to cool the globe’s surface. Moreover Arctic and Antarctic ice mass have grown in comparison to the previous years. …
From the “I scream, you scream, we all scream for higher temperatures” department. Yesterday, Paul Homewood and I went on a collaborative search to find the weather station at Strathclyde Park which had it’s all-time Scottish high temperature record denied by the Met Office, to no avail. It just wasn’t easily visible. One of Paul’s readers went to the scene and took photos, but it isnit just the photos, it’s what he found out. Photo credits to Duncan McNeil. Read on.
Two solar physicists, Robert Leamon from NASA Goddard Space Flight Center, and Scott McIntosh from the High Altitude Observatory at Boulder, CO, have made an interesting observation that links changes in solar activity with changes in the El Niño Southern Oscillation (ENSO).
As they reported at the AGU 2017 Fall Meeting, the termination of the solar magnetic activity bands at the solar equator that mark the end of the Hale cycle coincides since the 1960’s with a shift from El Niño to La Niña conditions in the Pacific.
The global temperature anomaly for June 2018 changed only slightly from May. Indeed the first six months of 2018 have been steady, varying in a narrow range between +0.26 and +0.18 °C. As noted last month, NOAA’s indication that an El Niño is coming this winter appears on track as we see tropical temperatures continue to inch upward.
2 July 2018 – “The Belgian department of solar physics research (SIDC) says we are about to touch 100; that is, a hundred days in which we do not see spots on our sun,” says Italian meteorologist Dr Carlo Testa.
During a time of few or no sunspots (a solar minimum) the Sun emits less energy than usual, says Dr Testa. “According to some scholars this situation could lead to climatic upheavals.”
Suffice it to recall, says Testa, that between 1645 and 1715 the most significant solar minimum of history, the Little Ice Age, occurred, bringing years and years marked by very strict winters that lasted until June. (…)
There have been articles on WUWT recently, here and here, commemorating the 30 years since James Hansen gave Senate committee testimony about his view of the human influence on climate
(…)
Hansen dramatically emphasized that “The most recent two seasons (Dec.-Jan.-Feb and Mar.-Apr.-May, 1988) are the warmest in the entire record.” This is really a non sequitur. It would be notable if the last point(s) in a long upward-trending series were not the warmest in the series. And, indeed, the 27 seasons preceding the two 1988 record temperatures were all lower than the 1981 seasonal high! (See the next graph, below) Basically, Hansen got lucky again that he had a couple of warm seasons that allowed him to make such a statement to impress the uncritical Senators. Otherwise, he would have had to truncate his graph at 1981 to make a similar claim. He also added an extra season of data to his ‘30-year’ time-series, probably to accentuate the claim. Two seasons sounds more impressive than one season.
As readers of my posts know, I’ve held for many years that there are a variety of emergent phenomena that regulate the earth’s temperature. See my posts The Thermostat Hypothesisand Emergent Climate Phenomena for an overview of my hypothesis.
One of the predictions derivable from my hypothesis is that the earth should be relatively insensitive to small changes in forcing. According to my hypothesis, if the total energy entering the system changes in such a manner that the global temperatures start to drop, inter alia the system responds through changes in the time and strength of the daily emergence of the tropical cumulus field and the associated thunderstorms. This allows more sunlight to enter the system and decreases the thunderstorm-caused surface heat losses, balancing out the energy lost elsewhere and maintaining the temperature.

COLDEST PLACE ON EARTH IS COLDER THAN SCIENTISTS THOUGHT
WASHINGTON — Tiny valleys near the top of Antarctica’s ice sheet reach temperatures of nearly minus 100 degrees Celsius (minus 148 degrees Fahrenheit) in the winter, a new study finds. The results could change scientists’ understanding of just how low temperatures can get at Earth’s surface, according to the researchers.
Scientists announced in 2013 they had found the lowest temperatures on Earth’s surface: Sensors on several Earth-observing satellites measured temperatures of minus 93 degrees Celsius (minus 135 degrees Fahrenheit) in several spots on the East Antarctic Plateau, a high snowy plateau in central Antarctica that encompasses the South Pole. But the researchers revised that initial study with new data and found the temperatures actually reach minus 98 degrees Celsius (minus 144 degrees Fahrenheit) during the southern polar night, mostly during July and August.
The Arctic and North Atlantic have suddenly turned surprisingly cold. First, according to Weatherbell meteorologist Joe Bastardi, the northern Atlantic has turned cold; so cold in fact that Bastardi called it “impressive”: …
All the Atlantic cold could have a big (positive) impact on the upcoming hurricane season, says hurricane expert Philip Klotzbach. One week ago Klotzbach tweeted …

The shocking thing is that Howard Lee has a degree in geology. The fact that he makes his living as an “Earth Science writer” and not as a geologist might just be relevant.
Can the Miocene tell our future? I’ll let Bubba’s mom answer that question:
A new paper about to be in press, comes at the end of a flurry of papers and reports published this week that claims Antarctica was losing ice mass. Zwally says ice growth is anywhere from 50 gigatons to 200 gigatons a year. NASA glaciologist Jay Zwally says his new study will show, once again, the eastern Antarctic ice sheet is gaining enough ice to offset losses in the west.
The new paper has zero mentions of the word. But other scientists have published plenty of papers describing how the West Antarctic zone is being warmed from below by 1200 degrees of magma. According to scientist Dustin Schroeder and co, it is as if the Thwaites Glacier in West Antarctic is sitting on a “stovetop burner”.[1]His words. Thwaites Glacier,, smack in the middle of the warming is being melted from below by geothermal heat. Then there is the large blob of superheated rock 60 miles below West Antarctica. The researchers use the phrase “like a blow-torch”…. Capping it off, only last year 91 new volcanoes were discovered 2km underneath the West Antarctic Rift. That’s new, as in, we didn’t know they were there.
Follow the reasoning, either a trace gas 10 kilometers up is causing some spots of Antarctica to warm and other parts to cool, or hot magma at 1,200C is. What’s more likely?
Water, H2O, determines the ‘General Background Temperature’ for the Earth, resulting in Hothouse and Ice House Climate States. During geological periods the movement of continents changes the position of
continents, oceans and seas. Because of the different configurations, a dominant warm or a dominant cold deep-water production configuration ‘sets’ average temperatures for the deep oceans. Changing vertical oceanic circulation changes surface temperatures, especially in the higher latitudes. During a Hot House State, higher temperatures in the high latitudes result in a high water-vapor concentration that prevents a rapid loss of thermal energy by the Earth.
These three processes, plate tectonics (continental drift), vertical oceanic circulation variability and variations in atmospheric water vapor concentration and distribution, caused previous Hot House and Warm House Climate States. A change in the working of those mechanisms resulted in a transition from the previous Hot House Climate State to the very cold ‘Ice House State’ that we live in now. That change was set in motion by the changing configuration of continents, oceans and seas.
Some have speculated that the distribution of relative humidity would remain roughly constant as climate changes (Allen and Ingram 2002). Specific humidity can be thought of as “absolute” humidity or the total amount of water vapor in the atmosphere. We will call this amount “TPW” or total precipitable water with units of kg/m2. As temperatures rise, the Clausius-Clapeyron relationship states that the equilibrium vapor pressure above the oceans should increase and thus, if relative humidity stays the same, the total water vapor or specific humidity will increase. The precise relationship between specific humidity and temperature in the real world is unknown but is estimated to be between 0.6 to 18% (10-90%ile range) per degree Celsius from global climate model results (Allen and Ingram 2002) …

A tiny clue found in ancient sediment has unlocked big secrets about Greenland’s past and future climate.
Just beyond the northwest edge of the vast Greenland Ice Sheet, Northwestern University researchers have discovered lake mud that beat tough odds by surviving the last ice age. The mud, and remains of common flies nestled within it, record two interglacial periods in northwest Greenland. Although researchers have long known these two periods — the early Holocene and Last Interglacial — experienced warming in the Arctic due to changes in the Earth’s orbit, the mix of fly species preserved from these times shows that Greenland was even warmer than previously thought.
