DNA Evidence Reveals Domestic Cats, Dogs, African Wildcats, Frogs Lived In The Arctic 9000 Years Ago

DNA Evidence Reveals Domestic Cats, Dogs, African Wildcats, Frogs Lived In The Arctic 9000 Years Ago

A new study finds warmth-demanding species could survive in the Holocene Arctic (northern Norway) hundreds to thousands of km north of where they reside today. This affirms temperatures were “higher than today” with much less snow and ice back then. DNA evidence from a site north of the Arctic Circle indicates African wildcat (Felis lybica) […]

Newly Discovered 90,000-Year-Old Human Footprints Reveal How Much Higher Sea Levels Used To Be

Newly Discovered 90,000-Year-Old Human Footprints Reveal How Much Higher Sea Levels Used To Be

Human footprints embedded into rock that used to be a sand beach at the limit of the seashore’s “swash flow” and high tide lie 20 to 30 meters above the present sea level. The footprints are dated to ~90,000 years ago. It is estimated that sea levels were globally about 6 to 9 meters higher […]

Water Vapor Absorbs 84 Times More Radiation Than CO2 ... Clouds Drove 89% Of 1982-2018 Warming

Water Vapor Absorbs 84 Times More Radiation Than CO2 … Clouds Drove 89% Of 1982-2018 Warming

“CO2 is only present in the atmosphere in trace amounts (0.04%) and lacks sufficient enthalpy to have any measurable effect on the atmosphere’s temperature.” – Nelson and Nelson, 2024 New research (Nelson and Nelson, 2024) further documents the inconsequential role that CO2 plays in climate. Less than 4% of longwave infrared radiation is absorbed by […]

Comprehensive Russian Temperature Reconstruction Shows Warmer Temperatures 1000 Years Ago!

Comprehensive Russian Temperature Reconstruction Shows Warmer Temperatures 1000 Years Ago!

Dr. Michael E. Mann and the IPCC claims of a hockey stick temperature trend are challenged. A paper published by a team of scientists of the Russian Academy of Sciences led by В. V. Klimenko presents a quantitative reconstruction of the mean annual temperatures of northeastern Europe for the last two millennia. The study was […]

Three More New Temperature Reconstructions Document A Warmer Medieval Period

Three More New Temperature Reconstructions Document A Warmer Medieval Period

The North Atlantic, the Pacific Northwest (USA), and northern Finland were all warmer than today between 1000 and 2000 years ago. Today’s (2000 CE) July air temperatures in the Azores – archipelago islands in the middle North Atlantic, ~1400 km west of Portugal – are visually shown to average about 10 to 11°C in a […]

Scientists Selectively Reject CO2 Measurements That Do Not Align With The Human-Caused Narrative

Scientists Selectively Reject CO2 Measurements That Do Not Align With The Human-Caused Narrative

Reconstructions of paleo CO2 levels openly rely on data derived from plant stomata. But when modern (1800s-present) CO2 measurements from stomata conflict with the narrative that humans drive CO2 levels, they are patently rejected. Scientists readily acknowledge plant stomata evidence from one location are “widely used as an effective tool for paleoenvironmental reconstructions” of global […]

2 Separate Studies Affirm No Net Temperature Or Precipitation Change In Pakistan Since The 1700s

2 Separate Studies Affirm No Net Temperature Or Precipitation Change In Pakistan Since The 1700s

Yet another region of the world has failed to cooperate with then anthropogenic global warming narrative. Asad et al., 2024 “The longest 10 years’ warm periods were observed during the early decades of the twentieth century (AD 1918–1927…)…” “The five hottest years (based on 7.33 °C ± 0.99 °C) were AD 1896 (9.80 °C), 1892 […]

3 More New Studies Affirm Sea Levels Were 5 to 9 Meters Higher Than Today 7000-5000 Years Ago

3 More New Studies Affirm Sea Levels Were 5 to 9 Meters Higher Than Today 7000-5000 Years Ago

Modern relative sea levels are near the lowest in the last 7,000 years. Two studies, independently published, identify Mid-Holocene sea levels in northern Norway (north of the Arctic circle) as 7 to 9 meters higher than today before declining to the present (Balascio et al., 2024, Nielsen et al., 2024). This region of the Arctic […]

Uncertainty In Natural Forcing From Wildfire, Dust Aerosols 2 Times Larger Than Total CO2 Forcing

Uncertainty In Natural Forcing From Wildfire, Dust Aerosols 2 Times Larger Than Total CO2 Forcing

The radiative effect of natural wildfire aerosol forcing alone can be said to fully cancel out the total accumulated forcing from 170 years of CO2 increases in the current climate. It has been estimated that the total change in climate forcing (radiation imbalance) from the 1750 to present CO2 concentration increase has been 1.82 W/m². […]

3 More New Studies Indicate There Has Been No Climate-Induced Precipitation Trend Since The 1800s

3 More New Studies Indicate There Has Been No Climate-Induced Precipitation Trend Since The 1800s

CO2-induced global warming was supposed to intensify the hydrological cycle and extreme precipitation. It hasn’t. New research (Mitchell and Knapp, 2024) at a southeastern United States study site indicates there has been no significant trend in either total precipitation or intense rainfall events (IRE) over the last 250 years (1770-2020). However, there was more IRE […]

New Alarmist Definition Of A Region's 'Rapid Climate Change' Is A Slight Cooling Trend Since 1960

New Alarmist Definition Of A Region’s ‘Rapid Climate Change’ Is A Slight Cooling Trend Since 1960

A  -0.005°C temperature change over a span of 60 years in northern Pakistan (Himalaya region) is ostensibly having “adverse impacts in multiple sectors.” The first sentence of a new paper’s (Khan et al., 2024) abstract claims: “Hindu Kush Himalaya region is experiencing rapid climate change with adverse impacts in multiple sectors.” But in the body […]

A New 1787-2005 Temperature Reconstruction Determines The Coldest 50-Year Period Was 1940-1993

A New 1787-2005 Temperature Reconstruction Determines The Coldest 50-Year Period Was 1940-1993

The warmest 50-year period in northeastern China occurred from 1844-1893. Li et al., 2024 “Compared with single years, in general, high or low temperatures that persist for many years will more significantly affect the growth of trees [30]. When we defined years with T12-1 ≥ −10.73 °C (Mean + 1σ) and T12-1 ≤ −12.61 °C […]
