New Science Affirms Arctic Region Was 6°C Warmer Than Now 9000 Years Ago, When CO2 Levels Were ‘Safe’

by K. Richard, July 12, 2018 in NoTricksZone


Unearthed new evidence (Mangerud and Svendsen, 2018) reveals that during the Early Holocene, when CO2 concentrations hovered around 260 ppm, “warmth-demanding species” were living in locations 1,000 km farther north of where they exist today in Arctic Svalbard, indicating that summer temperatures must have been about “6°C warmer than at present”.

Proxy evidence from two other new papers suggests Svalbard’s Hinlopen Strait  may have reached about 5 – 9°C warmer than 1955-2012 during the Early Holocene (Bartels et al., 2018), and Greenland may have been “4.0 to 7.0 °C warmer than modern [1952-2014]” between 10,000 and 8,000 years ago according to evidence found in rock formations at the bottom of ancient lakes (McFarlin et al., 2018).

In these 3 new papers, none of the scientists connect the “pronounced” and “exceptional” Early Holocene warmth to CO2 concentrations.

Global Sea Sea Surface Temperatures Have Seen “Pretty Dramatic Turnaround,” Says 40-Year Meteorologist!

by P. Gosselin, July 15, 2018 in NoTricksZone


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.

GLOBAL COOLING: GLOBAL TEMPS HAVE DROPPED BY 0.65C (1.2F DEGREE) SINCE 2016

by Marc Morano, July 13, 2018 in ClimateDepot


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.”

Conditions for formation of Super El Ninos determined

by Anthony Watts, July 12, 2018 in WUWT


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  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.

‘The Earth has a fever’ – the only solution is 14 billion air conditioners

by University of Birmingham, July 10, 2018 in WUWT


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

  • Harnessing waste resources: ‘wrong time’ renewables; waste cold; and waste heat.

  • 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

Ocean Temperature – Part 1

by Irek Zawadzki, July 10, 2018 in SkepticalScience


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.

Summer Causes Climate Change Hysteria

by Ph. D. Roy Spencer, July 2, 2018 in GlobalWarming


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.

The all time record high temperatures for Los Angeles are the result of a faulty weather stations and should be disqualified

by Anthony Watts, July 8, 2018 in WUWT


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.

Against The Forecasts: Sea Ice Grows…Surface Temperatures Fall… Troposphere Cools…Polar Regions Stable!

by P.  Gosselin, July , 2018 in NoTricksZone


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. …

Friday Funny: Scottish “record high temperature” caused by Ice Cream Truck

by Anthony Watts, July 6, 2018 in WUWT


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.

Solar minimum and ENSO prediction

by Javier, July 5, 2018 in WUWT


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.

UAH Global Temperature Report: June 2018

by Anthony Watts, July 3, 2018 in WUWT


Notes on data released July 2, 2018

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.

Quiet Sun: More than 3 months without a sunspot

by Dr Carlo Tesla, July 2, 2018 in A. Watts, WUWT


What if the worst is to come?” – Dr Carlo Testa.

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. (…)
