According to a new study, the recent short-term (2011-2022) decreasing Antarctic sea ice concentration (SIC) trend has not offset the overall 43-year (1979-2022) trend of increasing Antarctic SIC. The strongly negative sea surface temperatures and SIC correlation coefficient (-0.73) indicates the waters around Antarctica have undergone a long-term cooling trend. Image Source: Sahoo et al., […]

A new surface air climate reconstruction method (Roberts et al., 2025) has determined neither the entire region from 60-90°S (Southern Ocean, Antarctica) nor the continental US have undergone any unusual or unprecedented warming in the modern era. The 60-90°S region had much warmer-than-modern periods throughout the last 12,000 years. Image Source: Roberts et al., 2025

Charts by Kirye Text by Pierre The December, 2024, untampered mean temperature data from the Japan Meteorological Agency (JMA) are in for Tokyo and its Hachijojima island – there’s been no fall warming in decades for the month of December. First we present the latest plot of December mean temperatures for Tokyo since 1975: Data […]

Studies from Central China, Russia, and Central Europe indicate there was just as much (0r more) warming and drought prior to 1900, or when CO2 concentrations were under 300 ppm. A new 1606 to 2016 Central China winter (minimum) temperature reconstruction (Jiang et al., 2024) reveals cold periods only occurred in 9 years of the […]

Paleoclimate evidence affirms warmth reduces drought frequency and intensity. A new study utilizes Asian tree pollen records to affirm that for the last 8000 years centennial-scale warming periods were associated with reductions in drought, famines, crop failures. “…warm periods were associated with increased precipitation along with relatively short-lived drought events.” In contrast, centuries of cooling […]

Even though atmospheric CO2 rose from 337 ppm in 1979 to 420 ppm in 2022, there is no evidence of a warming trend across Antarctica during this period. According to a new study, Antarctica’s station data indicate a pronounced cooling trend by over -1°C (-0.53°C per decade) from 1979-1999. The cooling trend thereafter slowed to […]

New research indicates there has been no reduction in sea ice in Antarctica’s Robertson Bay (Ross Sea) during the last century. Instead, the frigid Little Ice Age and its expanded sea ice conditions continue unabated through the 20th and 21st centuries. Between ~8000 and 3500 years before present the Antarctic ice sheet experienced several millennia […]

Any 21st century ice melt across Greenland cannot be due to an accelerated warming trend, as the island as a whole has been cooling since the 1990s. New research analyzes two decades of Greenland land surface temperature (LST) data. Contrary to the popular narrative of a significant warming trend, Greenland has instead cooled from 2000-2019 […]

Scientists highlight yet another region that anthropogenic CO2 emissions have failed to do their “global warming” thing. Reconstructed and observed temperature trends reveal 120 years (1901-2022) of cooling across the southeastern US (King et al., 2024). Image Source: King et al., 2024 Over 100 years (1901-2015) of net cooling is also evident across the entire […]

Yet another region of the world has not been cooperating with the “global” warming narrative. A new study‘s reconstructed temperatures show no net warming in Central China over the last 250 years. The authors point out the observed temperatures from 1953-2020 closely align (r = 0.732) with the reconstructed 1953-2020 temperatures. This suggests the reconstructed […]

The globe may have only warmed by 0.41 to 0.83°C in the last 140 years. According to a new study, weather station data has been shown to non-climatically and erroneously record warmer-than-actual temperatures due to the steady and perpetual aging process almost universally observed in temperature gauges. When a weather station temperature gauge’s white paint […]

The GFS 7-day trend expects a strong cooling, especially in the northern hemisphere. Hat-tip: Snowfan here The 2m temperatures in the northern hemisphere are expected to fall by -0.34°C, which will also pull global temperatures down by -0.24°C.
