A new study indicates the Antarctic Peninsula has cooled -2.2°C (-1.2°C/decade) from 2003-2021. Of the 12 regions of Antarctica analyzed for temperature trends from 2003-2021, 6 cooled and 6 warmed. These trends undermine alarmist claims of CO2-induced “polar amplification.” Image Source: Nielsen et al., 2025

No global warming this year, and likely next year as well The NASA/GMAO ENSO forecasts remain consistent with the August 2025 forecasts, with La Niña conditions developing in the equatorial Pacific in the relevant Nino region 3.4 in the NH summer of 2025. Hat-tip: Snow Fan Source: NASA/GMAO ENSO forecasts Alarmists will likely shift their […]

Here’s what the ECMWF is forecasting for Europe the next 7 days: Source: ECMWF via Snowfan. Earlier this year, the usual suspects were putting out horror scenarios of a summer of heat and drought across Europe in 2025. The most extreme model runs, with temperatures soaring to 45°C, were presented as serious forecasts and as […]

What’s happened to the global temperature since 2023? By Frank Bosse, Klimanachrichten We remember: by mid-2023, the data on global temperatures had shown a very marked increase. It had gotten warmer globally quite quickly, by an incredible 0.5°C compared to 2022. This led to a new record for the year being announced in 2024. The […]

There has been a “marked cooling trend” across the North Atlantic in recent decades (Ryu and Kang, 2025). This includes ocean heat content decline (OHC) since the 2000s, and cooling sea surface temperatures (SST) since the mid-1990s. Image Source: Ryu and Kang, 2025

In his latest newsletter, German professor Fritz Vahrenholt reports how the global average temperature has decreased in June and early July 2025, and has seen a downward trend since January 2025. The deviation from the long-term average of satellite measurements is +0.48 degrees Celsius, with values continuing to drop in July. Despite this global development, […]

According to a new study, abrupt (±1-2°C per century) shifts in North Atlantic sea surface temperature (SST) have occurred routinely over the last 9000 years. These decadal- to centennial-scale climate changes were “induced by Holocene summer insolation and atmosphere-ocean internal variability.” The average SST throughout the 8.2 ka fluctuation was 10.0°C. The average 4.2 ka […]

Scientists have counter-intuitively determined that a melting Antarctic ice sheet serves to mitigate global warming. The anticipated accelerated melting of the Antarctic ice sheet (AIS) will mean massive amounts of freshwater will enter the Southern Ocean (SO) over the next one hundred years. According to a new study‘s panoply of SOFIA (Southern Ocean Freshwater Input […]

Europe is now dryer (and colder) than almost any other period in the last 9000 years. A new European Alps hydroclimate reconstruction spanning the years 8980 to 2014 CE has been derived from the stable isotopes of 192 trees (Arosio et al., 2025). The reconstruction clearly distinguishes centennial-scale warm periods such as the Medieval Warm […]

Cooling trends of up to -2.15°C per decade are not consistent with the “global warming” narrative. According to a new study (Li et al., 2025), 98% of the Central Eurasia study area (40-65°N and 50-130°E) experienced significantly declining temperatures from 2004-2020. Specifically, the region cooled by nearly -2.0°C – a rate of -1.425°C per decade […]

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
