New Study: 43 Years Of An Increasing Antarctic Sea Ice Trend

New Study: 43 Years Of An Increasing Antarctic Sea Ice Trend

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.

New Study: US And 60-90°S Temperature Trends Do Not Align With The Humans-Did-It Narrative

New Study: US And 60-90°S Temperature Trends Do Not Align With The Humans-Did-It Narrative

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

Climate Stagnation: Tokyo And Hachijojima Island Have Seen No December Warming In Decades!

Climate Stagnation: Tokyo And Hachijojima Island Have Seen No December Warming In Decades!

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 […]

3 More New Drought And Temperature Reconstructions Do Not Support The Climate Alarm Narrative

3 More New Drought And Temperature Reconstructions Do Not Support The Climate Alarm Narrative

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 […]

New Study: Over The Last 8000 Years Centennial-Scale Megadrought Periods Were Driven By Cooling

New Study: Over The Last 8000 Years Centennial-Scale Megadrought Periods Were Driven By Cooling

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 […]

Another New Study Reports A Lack Of A Long-Term Warming Trend Across Antarctica

Another New Study Reports A Lack Of A Long-Term Warming Trend Across Antarctica

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 […]

'Global' Warming? Little Ice Age Cooling And Sea Ice Expansion Is Still Ongoing Across Antarctica Today

‘Global’ Warming? Little Ice Age Cooling And Sea Ice Expansion Is Still Ongoing Across Antarctica Today

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 […]

New Study: Greenland Cooled by -0.11°C From 2000-2019 - Including All Ice Free And Ice Covered Areas

New Study: Greenland Cooled by -0.11°C From 2000-2019 – Including All Ice Free And Ice Covered Areas

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 […]

New Study: The Southeastern United States Has Been Cooling For The Last 120 Years

New Study: The Southeastern United States Has Been Cooling For The Last 120 Years

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 […]

New Study Finds There Has Been No Warming In Central China Since 1770

New Study Finds There Has Been No Warming In Central China Since 1770

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 […]

New Study: Systematic Error In 1880-2020 Global Temperature Measurements Inflates Warming By 42%

New Study: Systematic Error In 1880-2020 Global Temperature Measurements Inflates Warming By 42%

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 […]

NCEP GFS 7-Day 2m Temperature Trend Run Sees 0.34°C Fall

NCEP GFS 7-Day 2m Temperature Trend Run Sees 0.34°C Fall

 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.
