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...

Share this…FacebookTwitterScientists 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, no external […]

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...

Share this…FacebookTwitterThe 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 the global […]

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...

Share this…FacebookTwitterA 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 vs. sink […]

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

Share this…FacebookTwitterA 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.

Share this…FacebookTwitterGünther 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 warming. Pre-industrial […]

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...

Share this…FacebookTwitterIt 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 Little Ice […]

'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...

Share this…FacebookTwitter 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 concept to […]

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...

Share this…FacebookTwitterMarine 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 Urchins basking […]

Share this…FacebookTwitterIn a new climate reconstruction for the Tibetan Plateau (Liang et al., 2020), scientists report a) the highest Holocene temperatures occurred about 8,500 to 6,000 years ago; b) “century-scale climate fluctuations” correlate “statistically and visually” with solar forcing estimates; and c) “we are in the middle of the 500-yr-long relatively warm period” and “this […]

New Study: Sea Level Rise Along The North American Coast 'Not Necessarily Symptomatic Of Anthropogenic Forcing'

New Study: Sea Level Rise Along The North American Coast ‘Not Necessarily Symptomatic Of Anthropogenic Forcing’

Share this...

Share this…FacebookTwitterScientists suggest relative sea level changes are well-correlated with natural variability and accelerated sea level rise is a “recurring feature” of what has been observed for over 300 years. Five of six studied regions along the North American Atlantic coast show declining sea level rates (mm/yr) in recent decades. After retreating into the sea […]

5 New Studies: High Mountain Asia Glaciers Are Advancing, Surging…And This Is A ‘Natural Phenomenon’

Share this…FacebookTwitterGlacier surges of 100s of meters within mere months have been occurring throughout High Mountain Asia (the Karakoram region, especially) for decades, even centuries. It’s the Karakoram “anomaly”, and it’s thought to be “natural”. So why are the regions where glaciers are retreating thought to be responding to unnatural climate changes? The advancing glaciers […]

Share this…FacebookTwitterFrom 1993 to 2018, the satellite altimetry sea level changes reveal both positive and negative accelerations, align with oscillatory patterns, and are dominated by internal variability (e.g., PDO, ENSO). The “forced acceleration pattern” assumed to be associated with anthropogenic global warming “has not emerged”. Image Source: Hamlington et al., 2020 Negative or negligible sea […]
