DNA evidence suggests the limit of Antarctic sea ice was ~2000 kilometers farther south than it is today 2500 to 1000 years ago. Elephant seals can only breed in the Southern Ocean’s subantarctic, sea ice free waters. For example, today’s largest colony breeds on Macquarie Island (54.5°S). Scientists (Wood et al., 2025) have now identified […]

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., […]

The Surface Mass Balance (SMB) for the Antarctic Ice Sheet (AIS) has been remarkably stable since the 1970s. However, according to the authors of a new study (a preprint soon to be published), “in recent years, the SMB has increased on the AIS, in particular for 2022, which mostly originates from mass gain on the […]

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

Yet another region of the globe has failed to cooperate with anthropogenic “global” warming narrative. According to climate models constructed on the presumption that CO2 concentration changes are the driver of climate, Central Africa should have been warming in recent centuries in tandem with the rise of atmospheric CO2. However, scientists (Ménot et al., 2025) […]

Leafy moss dated to the Medieval Warm Period (MWP) has been found embedded in Antarctic glacier ice that today is “permanently snow-covered” with “no evidence of meltwater.” This affirms a warmer MWP and that “the summer melt during the MWP was greater than today.” According to a new study, moss samples with intact leaves and […]

Even if the entirety of the modern CO2 concentration increase is due to human activity, the impact (pressure) on global temperatures amounts to no more than 15-18%. In a new study, geology professor Dr. Wojciech Stankowski has summarized some of the reasons why the prevailing narrative that says humans can drive climate change by burning […]

Coral reefs expand and thrive as sea levels rise, whereas they undergo millennia of growth hiatuses and “turn-off” or “mass mortality” phases when sea levels fall. According to a new global sea level reconstruction (Feldman et al., 2025), global sea levels were meters higher than today 7000 to 5000 years ago. Global sea levels fell […]

The alarmist narrative that says disappearing sea ice serves to enhance and worsen global warming may now be discarded. For decades it has been assumed the sea ice concentration (SIC) reduction trend in the the Arctic over the first 30 years of the satellite era (1979-2007, with a flat trend since then) would lead to […]

“[T]he increase in absorbed solar radiation is primarily due to natural variations in cloudiness and surface albedo, which have served as the main forcing factors of the flux above the atmosphere over the last 2 decades.” – Diodato et al., 2025 It is commonly accepted that there has been a satellite-observed (CERES) cloud cover albedo […]

“The last four decades of global warming have led to a net gain in life expectancy.” – Piotr Walkowiak et al., 2025 Throughout Europe, exposure to harsh winters in colder climates is a greater mortality threat than living in warm climates with very hot summers. Succinctly put, warmer, milder winters save lives, whereas cold weather and […]

“Until now, the origin of the climate dynamics of the Central Andes during the last millennium has been speculative. On the basis of statistical evidence, we have identified solar variability as its origin.” – Schittek et al., 2025 In a new study, scientists have determined: 1) The Little Ice Age (LIA) was a global-scale cold […]
