50 Inverted Hockey Sticks - Scientists Find Earth Cools As CO2 Rises

50 Inverted Hockey Sticks – Scientists Find Earth Cools As CO2 Rises

Modern ‘Warmth’ A Brief Excursion From 8,000-Year (Continuing) Cooling Trend The scientific literature is replete with evidence that the geological record for the Holocene (the last 10,000 years) fails to support the concept that rising atmospheric CO2 concentrations cause ocean and land temperatures to rise. Actually, the scientific literature strongly suggests that the correlation between […]

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 […]

New Paper Indicates There Is More Arctic Sea Ice Now Than For Nearly All Of The Last 10,000 Years

New Paper Indicates There Is More Arctic Sea Ice Now Than For Nearly All Of The Last 10,000 Years

Solar Forcing Of Modern, Historic Arctic Sea Ice Only Slightly Less Sea Ice Now Than Little Ice Age In a new paper (Stein et al., 2017), scientists find that Arctic sea ice retreat and advance is modulated by variations in solar activity. In addition, the sea ice cover during the last century has only slightly […]

35 Scientific Papers: Global Sea Levels Were 1 - 2 Meters Higher Than Now For Most Of The Last 7,000 Years

35 Scientific Papers: Global Sea Levels Were 1 – 2 Meters Higher Than Now For Most Of The Last 7,000 Years

CO2 Concentration Changes Do Not Drive Sea Levels From about 7000 years ago to 2000 years ago, or from the Mid- to Late-Holocene, atmospheric CO2 concentrations varied between only about 260 and 270 parts per million, or ppm.  Such low CO2 concentrations are believed to be “safe” for the planet, as they are significantly lower […]

Could A New Global Temperature Reconstruction Using Ice Cores Be More Accurate Than The Instrumental Record?

Could A New Global Temperature Reconstruction Using Ice Cores Be More Accurate Than The Instrumental Record?

Global Temperature ‘Truth’ Changes With The Times In the early 1950s, the accepted scientific truth — as determined by thermometer records available at the time — was that global mean temperatures had risen by 0.7°C between 1860 and 1940.   Willett, H. C. 1950. “Temperature Trends of the Past Century” Centenary Proc. Royal Meteorol. Soc., pp. […]

New Paper: 14 Scientists Affirm Solar Forcing, Not CO2, Is 'Dominant Control' For Modern Climate Change

New Paper: 14 Scientists Affirm Solar Forcing, Not CO2, Is ‘Dominant Control’ For Modern Climate Change

One of the oft-stated “truths” for advocates of the position that humans are predominantly responsible for climate changes is that the Sun could not have played more than a negligible role in the global warming of the last few centuries. Indeed, the latest Intergovernmental Panel on Climate Change (IPPC) report theorizes that the long-term solar […]

The Hockey Stick Collapses: 60 New (2016) Scientific Papers Affirm Today’s Warming Isn’t Global, Unprecedented, Or Remarkable

Two fundamental tenets of the anthropogenic global warming narrative are (1) the globe is warming (i.e., it’s not just regional warming), and (2) the warming that has occurred since 1950 can be characterized as remarkable, unnatural, and largely unprecedented.  In other words, today’s climate is substantially and alarmingly different than what has occurred in the […]

1977 Spiegel Warned Of Little Ice Age Soon: "Widespread Glaciation" ..."Temperature Has Fallen 0.3°C"!

1977 Spiegel Warned Of Little Ice Age Soon: “Widespread Glaciation” …”Temperature Has Fallen 0.3°C”!

Back in the 1970s, many media outlets warned of global cooling and even a possible coming ice age. For example here I wrote about how Spiegel in 1974 grimly reported of threatening global cooling and that the odds of global warming were “at best” only 1 in 10,000! Current warm period “coming to an end” […]

Scientists: Greenland Is Now Much Colder With More Advanced Ice Sheet Margins Than 90% Of The Last 7,500 Years

Fifteen international scientists recently collaborated to assemble one of the most comprehensive analyses of temperature and ice sheet changes for Greenland and the Canadian Arctic ever produced.  Briner et al., (2016) synthesized over 100 records from a large and accumulating database to publish “Holocene climate change in Arctic Canada and Greenland” in the journal Quaternary […]

Another New Paper Reveals No Discernible Human Influence On Global Ocean Temperatures, Climate

Another New Paper Reveals No Discernible Human Influence On Global Ocean Temperatures, Climate

Three years ago, when the Rosenthal et al. (2013) paper was made available online from the journal Science, there was a bit of a stir among the purveyors of the humans-control-climate-with-their-CO2-emissions paradigm. Climate activist Michael Mann, for example, was ostensibly quite unhappy that a Medieval Warm Period (with +0.65°C warmer-than-now intermediate [0-700 m] ocean temperatures) was prominently […]

Oceans Warmed 6 Times Faster Than Modern Rates During The Mid-Holocene Annotated graph from Rosenthal et al. (2013) illustrating the steep amplitude of natural variations in ocean heat It has long been acknowledged by scientists that significant changes in deep ocean heat content have occurred in the past in the absence of changes or forcing […]

8 New Papers Reveal 'Natural' Global Warming Reaches Amplitudes Of 10°C In Just 50 Years With No CO2 Influence

8 New Papers Reveal ‘Natural’ Global Warming Reaches Amplitudes Of 10°C In Just 50 Years With No CO2 Influence

Climate records from ice cores indicate that abrupt, global-scale warming events with amplitudes of up to 10°C (in the Greenland region) were reached within as little as 50 years dozens of times during the roughly 100,000 years between the last interglacial (~120,000 years ago) and the current interglacial period (11,700 years ago to present).  That’s […]

Scientific Studies Reveal No Correlation Between CO2 And Ocean Heat Content Variations For 99.975% Of The Last 10,000 Years

Scientific Studies Reveal No Correlation Between CO2 And Ocean Heat Content Variations For 99.975% Of The Last 10,000 Years

“The current eager acceptance of oceanic thermal lag as the ‘explanation’ as to why CO2 warming remains undetected, reemphasizes that the atmosphere cannot warm until the oceans do. The logical implication follows that most current climate models are lacking in relevance; they have not been constructed with ocean surface temperature as the fundamental variable. When […]

Revealed: IPCC Adds 0.3°C Of Phantom Warming Between 3rd, 5th Reports ... Met Office Removes 0.3°C From 1880s-1940s Warming

Revealed: IPCC Adds 0.3°C Of Phantom Warming Between 3rd, 5th Reports … Met Office Removes 0.3°C From 1880s-1940s Warming

In the IPCC’s 2001 third report (TAR), the total surface temperature increase for the 20th century was reported to be “about 0.6°C”. IPCC TAR (2001): “The global average surface temperature has increased over the 20th century by about 0.6°C.” This Met Office graph of global temperatures for 1860-2000 was included in the IPCC’s 2001 report.
