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

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 […]

New Paper: Human Climate Forcing ‘Below Detection’ ... Deep Oceans Warm By ‘2°C Within 200 Years’ 100% Naturally

New Paper: Human Climate Forcing ‘Below Detection’ … Deep Oceans Warm By ‘2°C Within 200 Years’ 100% Naturally

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 from CO2.  Stott et al. (2007), for example, conclude that deep […]

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.

18 New Papers Link High Solar Activity To Medieval And Modern Warmth, Low Solar Activity To Little Ice Age Cooling

18 New Papers Link High Solar Activity To Medieval And Modern Warmth, Low Solar Activity To Little Ice Age Cooling

“It is generally accepted that the climate warms during periods of strong solar activity (e.g., the Medieval Warm Period) and cools during periods of low solar activity (e.g., the Little Ice Age).” —Lyu et al., 2016 Within the last 1,000 years, global-scale surface temperatures underwent a warm period during Medieval times, centennial-scale cooling during the […]

Scientists: The Arctic Was Sea-Ice-Free, 19°C Warmer 4 Million Years Ago -- And Yet Polar Bears Somehow Survived

Scientists: The Arctic Was Sea-Ice-Free, 19°C Warmer 4 Million Years Ago — And Yet Polar Bears Somehow Survived

“Whether polar bears are 350,000 years old or 6 million years old, unless we take action to curb greenhouse gas emissions, they face a future where the climate will continue to warm. And this warming will be unlike anything polar bears have survived before.”  —  Polar Bears International Image: NoTricksZone During the Pliocene, or from […]

Distinguishing Between 'Safe' or 'Dangerous' Warming Is Easy: 'Dangerous' Warming Is Red

Distinguishing Between ‘Safe’ or ‘Dangerous’ Warming Is Easy: ‘Dangerous’ Warming Is Red

When Michael Mann and the IPCC coordinated efforts to make the Medieval Warm Period disappear from the paleoclimate record in the early 2000s, they employed the visually slick and effective tactic of adding red to the “dangerous” warming trend, and blue to the “safe” cooling trend.  The original Mann et al. (1998, 1999) graph that […]

30 Scientific Papers Reveal Inverse CO2 - Sea Level Signal:  As CO2 Rises, Sea Level Falls

30 Scientific Papers Reveal Inverse CO2 – Sea Level Signal: As CO2 Rises, Sea Level Falls

According to the IPCC (2013),  global sea levels rose by less than two-tenths of a meter (0.19 m) between 1901 and 2010.  Considering the scientific record of long-term sea level trends from locations across the globe, this small <0.2 m change in sea levels over the course of the last 110 years does not even […]
