Swiss Climate Institute Director: "Absurd" To Call CO2 "Pollutant...Main Culprit Behind Climate Change"

Swiss Climate Institute Director: “Absurd” To Call CO2 “Pollutant…Main Culprit Behind Climate Change”

A new research institute in Switzerland set to rock the climate science boat…will investigate natural causes of climate change. Director calls claims CO2 the main driver and a pollutant “absurd”. Swiss institute director and climate scientist Hans-Joachim Dammschneider says natural factors in large part behind recent climate change.

Another Bust: PAGES 2k 'Global' Reconstruction Fails To Confirm The 'Hockey Stick'

Another Bust: PAGES 2k ‘Global’ Reconstruction Fails To Confirm The ‘Hockey Stick’

A Deconstruction Of The PAGES 2k ‘Hockey Stick’ Image adapted from PAGES 2k, 2015 Five years ago, the release of the PAGES 2k Consortium (2013) “global” temperature data set was accompanied by a great deal of fanfare. Advocates deemed the conglomeration of proxy temperature data from 7 land regions as scientific confirmation of the notorious hockey-stick-shaped temperature […]

A Teetering Consensus: 97 New Papers Amassed In 2018 Support A Skeptical Position On Climate Alarm

The Science Unsettles Image Source: Robertson and Chilingar, 2017 In just the first 8 weeks of 2018,  97 scientific papers have been published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly […]

The Proliferation Of Non-Global Warming Graphs In Science Journals Continues Unabated In 2018

The Proliferation Of Non-Global Warming Graphs In Science Journals Continues Unabated In 2018

 Already 14 New (2018) Non-Hockey Stick Papers During 2017, there were 150 graphs from 122 scientific papers published in peer-reviewed journals that indicated modern temperatures are not unprecedented, unusual, or hockey-stick-shaped — nor do they fall outside the range of natural variability. Less than 3 weeks into the new publication year, the explosion of non-alarming […]

2 More New Papers Affirm There Is More Arctic Ice Coverage Today Than During The 1400s

2 More New Papers Affirm There Is More Arctic Ice Coverage Today Than During The 1400s

 A Shrinking Anthropogenic Signal  Continues To Emerge In The Arctic Earlier this year, Stein et al., 2017 published a reconstruction of Arctic sea ice variations throughout the Holocene that appeared to establish that there is more Arctic sea ice now than for nearly all of the last 10,000 years. The study region, the Chukchi Sea, […]

Almost 300 Graphs Undermine Claims Of Unprecedented, Global-Scale Modern Warmth

Almost 300 Graphs Undermine Claims Of Unprecedented, Global-Scale Modern Warmth

Hundreds Of Scientific Papers Challenge ‘Global’ Warming Recently, an article citing over 80 graphs from scientific papers published in 2017 — and another 55 graphs from 2016  — established that modern “global” warming is not actually global in scale, and that today’s warmth is neither unprecedented or remarkable when considering the larger context of natural variability. Here, an additional […]

Historical Grape Harvest Dates Show Modern Temperatures No Warmer Now Than Most Of The Last 1,000 Years

Historical Grape Harvest Dates Show Modern Temperatures No Warmer Now Than Most Of The Last 1,000 Years

Grape Harvest Date Evidence: No Significant Modern Warmth Public domain photo. Source here In a late February (2017) interview on a U.S. news program, mechanical engineer Bill Nye claimed that the settled science says humans have been warming the planet at a rate that is  unnaturally and “catastrophically” fast since the year 1750 . “It’s […]
