“From modern instrumental carbon isotopic data of the last 40 years, no signs of human (fossil fuel) CO2 emissions can be discerned.” – Koutsoyiannis, 2024 It is routinely claimed that a telltale sign human emissions (fossil fuels) have irrevocably altered the atmospheric CO2 concentration is a declining trend in carbon isotope 13 (δ13C), considered an […]

The warming of the oceans since the turn of the century can easily be explained by the increasing trend in absorbed solar radiation. Earth’s energy imbalance was determined to be +0.6 W/m² during the first decade of the 21st century (Stephens et al., 2012) using satellite observations. However, uncertainty in this positive imbalance value is […]

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 […]

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 […]

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 […]

Ice flowed out of the interior of the Greenland ice sheet at much stronger rates and with much greater variability than today throughout the Holocene – or until about 2,000 years ago. New research (Jansen et al., 2024) has determined Greenland’s ice streams vary according to internal processes, and not necessarily due to external changes […]

Retreat rates for the West Antarctic Ice Sheet (WAIS) were massive during the Early Holocene, when CO2 concentrations were low and stable (~265 ppm), dwarfing any retreat rates witnessed in the modern era. New research published in Nature Geoscience (Grieman et al., 2024) assesses the elevation of West Antarctica’s ice sheet fell by ~480 m within […]

Relative sea level change over the Holocene documents a much warmer past than today. Because it was so much warmer during the Early to Middle Holocene (~8000 to ~4000 years ago), there was significantly less water locked up on land (Greenland, Antarctica) in the form of ice sheets and glaciers. Instead, this water occupied ocean […]

“Here, we have demonstrated a major discrepancy between observation-based and climate model-based historical trends in near-surface atmospheric water vapor in arid and semi-ari regions.” – Simpson et al., 2024 A new study published in PNAS has demonstrated, once again, that climate models fail to simulate what happens in the real world with regard to fundamental […]

Scientists have found evidence that the coastal land area grew (prograded) by 120 meters from 1900 to 1985 at a study site in central Denmark. Per a new study, relative sea levels (RSL) in central Denmark were “~4.5 m higher than present between c. 6.6 and 5.9 ka ago.” After this highstand, RSL declined towards […]

The globe’s cities are warming primarily due to declining albedo, not CO2 radiative forcing. According to a comprehensive new study published in Remote Sensing of Environment, CO2 fertilization has led to an enhanced greening trend in 72.6% of cities across the world since 1985, accelerating to 89.2% since 2001. Per the authors, this greening trend […]

The shallowest sea surface temperature measurement limit is 10,000 times deeper than the extent of CO2’s radiative influence. When sea surface temperatures (SSTs) are measured, the depth range of the measurement typically extends from 10 cm to 10 m, or 100 mm to 10,000 mm (Merchant et al., 2019). Image Source: Merchant et al., 2019 […]
