Sea Level Manipulation

by Nils-Axel Mörner, August 5,  2017, in  J. Eng.Sci.Invention


Sea level changes is a key issue in the global warming scenario. It has been widely claimed that sea is rising as a function of the late 20th’s warming pulse. Global tide gauge data sets may vary between +1.7 mm/yr to +0.25 mm/yr depending upon the choice of stations. At numerous individual sites, available tide gauges show variability around a stable zero level …

… In this situation, it is recommended that we return to the observational facts, which provides global sea level records varying between ±0.0 and +1.0 mm/yr; i.e. values that pose no problems in coastal protection.

Solar Cycle Continues To Be The Weakest In 2 Centuries

by  F.  Bosse and  F. Vahrenholt, August 23, in NoTricksZone


The sun was completely free of spots on 11 days in July. Notable: while during last month the sun’s northern hemisphere was more active (in June all sunspots were in the northern hemisphere), last month the southern hemisphere was the most active part with 60% of the sunspots appearing there. The following diagram shows the course of solar cycle 24 thus far (…)

Big data finds the Medieval Warm Period – no denial here

by Jennifer Marohasy, August 22, 2017


Our results show up to 1°C of warming. The average divergence between the proxy temperature record and our ANN projection is just 0.09 degree Celsius. This suggests that even if there had been no industrial revolution and burning of fossil fuels, there would have still been warming through the twentieth century – to at least 1980, and of almost 1°C.

Most of the Recent Warming Could be Natural

by Jennifer Marohasy, August 21, 2017


AFTER deconstructing 2,000-year old proxy-temperature series back to their most basic components, and then rebuilding them using the latest big data techniques, John Abbot and I show what global temperatures might have done in the absence of an industrial revolution.  The results from this novel technique, just published in GeoResJ, accord with climate sensitivity estimates from experimental spectroscopy but are at odds with output from General Circulation Models.

 

Will 2017 Set Records? (Now Includes June and July Data)

by Werner Brozek, August 20, 2017 in WUWT


In order to determine if records are possible in 2017, one must know the previous records as well as the average to date and what is required for the rest of the year in order for a particular data set to set a new record.

For the five data sets I cover, records were set in 2016. For now, I am not concerned about the statistical significance of the records, nor the number of decimal places. I merely want to know if the record can be beaten this year. At the end of the year, I plan on reporting any records and how statistically significant they are.

An Inconvenient Deception: How Al Gore Distorts Climate Science and Energy Policy

by Roy W.  Spencer, Ph. D., August 19, 2017 in GlobalWarming


Al Gore has provided a target-rich environment of deceptions in his new movie.

After viewing Gore’s most recent movie, An Inconvenient Sequel: Truth to Power, and after reading the book version of the movie, I was more than a little astounded. The new movie and book are chock-full of bad science, bad policy, and factual errors.

The Little Ice Age And Medieval Warming In South Africa

by Paul Homewood, August 19, 2017


The climate industry likes to pretend that the Little Ice Age was just a local event in Europe, but studies like this one give the lie to that.

Interestingly this Tyson study also includes graphs of historical temperature trends in other parts of the world, for comparison. They all clearly show the MWP and Little Ice Age, although the peaks and troughs don’t always match.

Study validates East Antarctic ice sheet to remain stable even if western ice sheet melts

by Indiana University, August 17, 2017 in ScienceDaily


“There are models that predict that the interior of the East Antarctic ice sheet wouldn’t change very much, even if the West Antarctic ice sheet was taken away,” Licht said. According to these models, even if the ice sheet’s perimeter retreats, its core remains stable.

What do we know about Arctic sea ice trends?

by Dr. Ronan Connolly & Dr. Michael Connolly, August 16, 2017 in WUWT

Satellite observations indicate that the average Arctic sea ice extent has generally decreased since the start of the satellite records in October 1978. Is this period long enough to assess whether the current sea level trend is unusual, and to what extent the decline is caused by humans?

This change in Arctic climate is often promoted as evidence that humans are causing drastic climate change. For instance, an April 29th 2017 article in the Economist (“Skating on thin ice”, pg 16) implied that the Arctic is melting unusually, dramatically and worryingly (…)


 

The Global Temperature Record Is A Farce

by Tony Heller, August 16, 2017 in DeplorableClimSciBlog


NASA says  97% of scientists agree that their temperature graphs are accurate, and NASA, NOAA, CRU and JMA all independently agree very precisely about global temperature going back to 1880.

This is quite remarkable, considering that NASA doesn’t agree with their own data, having doubled 1880-2000 warming over the past 15 years.

Record-shattering 2.7-million-year-old ice core reveals start of the ice ages

by Paul Voosen, August 15, 2017


Scientists announced today that a core drilled in Antarctica has yielded 2.7-million-year-old ice, an astonishing find 1.7 million years older than the previous record-holder

If the new result holds up, says Yige Zhang, a paleoclimatologist at Texas A&M University in College Station, the proxies will need to be recalibrated. “We have some work to do.”
