Weather and climate analyst Schneefan here writes of “early frost” in the Arctic and how Greenland snow and ice have grown after being hit by a “snow bomb”. This contradicts the expectations of global warming alarmists.
The polar summer this year appears to have ended prematurely. The mean temperature of the central Arctic above 80°N has remained under the long-term average over the entire summer and even dipped below the freezing point about a week earlier than normal (1958-2002 mean).

Various sources, scientists publishing their opinion in the media, claim that Tropical Storm Harvey, recently landed in Texas, is one more signal of the influence of global warming on such catastrophic events. These claims are based on model calculations. Let’s examine the facts.

In the press release for a newly published and controversial peer-reviewed scientific paper, Australian scientist Dr. Jennifer Marohasy unveiled one of climate science’s better-kept secrets.
She and her colleagues are well aware that the post-1940s Northern Hemisphere (NH) proxy evidence from tree-rings, bore holes, pollen, etc., consistently fails to affirm sharply rising temperatures from the late 20th century onwards.

Way back in February, Global Weather Oscillations (GWO) veteran meteorologist David Dilley predicted that the 2017 Atlantic hurricane season would be “the most dangerous and costliest in 12 years for the United States.” (…)

What is causing the death of the polar bear as a climate change icon? Fat bears are part of it, but mostly it’s the fact that polar bear numbers haven’t declined as predicted.

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.

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.

Last year, experts announced that the Arctic would be ice-free in 2017.

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.

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.

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 (…)

“Since there is no universally accepted definition for Earth’s average temperature, several different groups around the world use slightly different methods for tracking the global average over time, including:
NASA Goddard Institute for Space Studies
NOAA National Climatic Data Center
UK Met Office Hadley Centre”

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.

While we obsess about climate change and debate if we live in the Anthropocene, we prepare poorly or not at all for natural forces like volcanoes that can level cities. This is folly we can no longer afford. Experts recommend a simple first step to better protect ourselves. Let’s start listening, or nature will teach us an expensive lesson.

Here’s a good example of how climate alarmists and leftists in Germany react when confronted with different opinions or the truth. It just illustrates the brand of radicalism we’re up against.
