Scientists Again Affirm Natural Warmings Of  5–16 °C In 'A Few Decades' Can Be 'Entirely Unforced'

Scientists Again Affirm Natural Warmings Of 5–16 °C In ‘A Few Decades’ Can Be ‘Entirely Unforced’

Share this… Facebook TwitterA new study asserts that when Greenland naturally warms by multiple degrees per decade, this “abrupt climate variability can result entirely from unforced or noise-induced oscillations of the coupled atmosphere-ice-ocean system.” This means the recent modest climate changes for Greenland may easily fall within the scope of an unforced natural variability pattern.

No Mention Of CO2: New Study Shows African Climate Variability Strongly Linked To Natural Cycles

No Mention Of CO2: New Study Shows African Climate Variability Strongly Linked To Natural Cycles

Share this… Facebook TwitterAfrica climate variability linked to natural oceanic and solar cycles, a new study affirms. No mention of CO2.  Image source: “Decadal and multidecadal natural variability of African rainfall“. A new study analyzes patterns of natural rainfall variability and can provide crucial assistance to African countries in seasonal rainfall forecasting for agriculture and […]

New Study: Drought In Western US Is 84% Driven By Internal Variability And 16% By Ocean Cooling

New Study: Drought In Western US Is 84% Driven By Internal Variability And 16% By Ocean Cooling

Share this… Facebook TwitterAn assessment of the 1856-2012 drought frequency/intensity along the US West Coast leaves no role for human activity in hydroclimate. Across the globe, no clear precipitation trends have been observed in the last several decades (Nguyen et al., 2018) Image Source: Nguyen et al., 2018 Instead of an intensification of the hydrological […]

Over 400 Scientific Papers Published In 2020 Support A Skeptical Position On Climate Alarm

Over 400 Scientific Papers Published In 2020 Support A Skeptical Position On Climate Alarm

Share this… Facebook Twitter In 2020, more than 400 scientific papers were 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 endorsed by policymakers and mainstream media sources. Over 400 […]

New Research Shows The Oceans Can 'Spontaneously' Warm 8°C In Under 100 Years 'Without External Trigger'

New Research Shows The Oceans Can ‘Spontaneously’ Warm 8°C In Under 100 Years ‘Without External Trigger’

Share this… Facebook TwitterScientists are increasingly finding that abrupt, decadal-scale temperature changes of multiple degrees Celsius can arise unforced and spontaneously. The surface temperatures for the Greenland ice sheet have been known to warm 8 to 16°C “within decades or less” – yes,  fewer than 10 years – due to “unforced oscillations.” In other words, […]

New Study Effectively Eliminates Confidence In Human Attribution For Modern Global Warming

New Study Effectively Eliminates Confidence In Human Attribution For Modern Global Warming

Share this… Facebook TwitterThe forcing uncertainties and lack of observational measurements in the top-to-bottom global ocean preclude an assessment that modern warmth is due to anthropogenic activities. Key points from a new paper (Gebbie, 2021): • 93% of the changes to the Earth’s energy budget, manifested as warming of the Earth system, are expressed in […]

Scientists Just Discovered Their Past Carbon Budget Guesses Have All Along Been Twice As Wrong As They Thought

Scientists Just Discovered Their Past Carbon Budget Guesses Have All Along Been Twice As Wrong As They Thought

Share this… Facebook TwitterA new assumption about carbon budgets reveals climate scientists have been vastly underestimating (by a factor of 2) the amount of carbon absorbed by the ocean for decades. Every past carbon budget estimate has been twice as wrong as the current estimate. When it comes to the ocean heat fluxes and source […]

Policymakers Misled...New Nature Study "Casts Doubt On Forecasts Of Regional Climate Change"

Policymakers Misled…New Nature Study “Casts Doubt On Forecasts Of Regional Climate Change”

Share this… Facebook TwitterA new paper reveals that climate models have failed to take important natural factors, such as the North Atlantic Oscillation, into account in their climate models on which leaders have been basing their policies.   A new paper in Nature says NAO not taken adequately into account by climate models.

Large Increase In Number Of Sunshine Hours Likely Behind Warming, Glacier Retreat In Alps Since 1980

Large Increase In Number Of Sunshine Hours Likely Behind Warming, Glacier Retreat In Alps Since 1980

Share this… Facebook TwitterGünther Aigner released a German video with the title “Die Alpengletscher im Klimawandel: Status quo“ (The Alps glaciers in climate change: status quo). Hat-tip: Die kalte Sonne Today global warming alarmists insist blaming climate change on man-made CO2 emissions. Yet, everywhere we look it’s difficult to find any correlation between CO2 and […]

Natural Variability: The Northern Hemisphere Cooled And Warmed By 1°C In Decades ~1500 Years Ago

Natural Variability: The Northern Hemisphere Cooled And Warmed By 1°C In Decades ~1500 Years Ago

Share this… Facebook TwitterIt is claimed Earth’s surface has warmed by 1°C in the last 140 years – which is a supposedly rapid climate change. But a new study suggests the Northern Hemisphere surface naturally cooled by 1°C in 8 or 9 years, then warmed up again by 1°C within decades during the Late Antique […]

'Most Of The Globe' Could Experience 'No Warming' For 30 Years Due To Temperature-Driving Internal Variability

‘Most Of The Globe’ Could Experience ‘No Warming’ For 30 Years Due To Temperature-Driving Internal Variability

Share this… Facebook Twitter A new study documents the dominance of internal variability in decadal-scale global temperature changes and suggests we may experience a global cooling trend during the next 15 or even 30 years despite rising greenhouse gases. Maher et al. (2020) acknowledge that internal variability in global surface temperature variations is “a difficult […]

When Exposed To Natural, Long-Term Extreme 'Ocean Acidification', Coral And Urchin 'Persist' And Even 'Thrive'

When Exposed To Natural, Long-Term Extreme ‘Ocean Acidification’, Coral And Urchin ‘Persist’ And Even ‘Thrive’

Share this… Facebook TwitterMarine species subjected to high CO2 extremes – 8,891 to 95,000 ppm – in their natural environments may not be adversely affected. They may even “thrive”. Earlier this year we highlighted a study that says coral reefs “thrive” near seafloor volcanic vents where CO2 concentrations reach 60,000 to 95,000 ppm. Image Source: PHYS.ORG […]
