Three new tree ring reconstructions (spanning 1320-2021, 1720-2014, and 1657-2020 CE) document the dominance of natural variability in the paleoclimate record. In the last 300 to 700 years, no precipitation pattern has emerged in Scandinavia, Asia, or Central Greece which can be linked to anthropogenic impacts or post-1950 CO2 increases (Stridbeck et al., 2026, Cai […]

Another anthropogenic global warming (AGW) modeling failure emerges in observed tropical cyclone data. According to climate modeling (Knutson et al., 2015 and 2020), everyday human activities such as driving cars and using cell phones (AGW) should lead to increases in tropical cyclone (TC) landfall frequency and intensity (i.e., accumulated cyclone energy [ACE], or maximum windspeed). […]

Natural atmospheric circulation patterns (like the Western Tibetan Vortex, or WTV) drive total cloud cover (TCC) change, which, in turn modulate the the amount of downward solar radiation reaching the surface. Over southwest Asia, or the Tibetan Plateau, scientists (Wang et al., 2026) indicate the satellite-observed increase in downward shortwave (DSW) “is the primary driver” […]

“The results indicate that extremes in heat-related metrics for daily T [Max] in the summer have not increased and in fact often show modest declines since 1899, due mostly to the early heat events during 1925-1954.” – Christy, 2026 The contiguous United States (CONUS) has the most reliable and comprehensive long-term daily maximum and minimum […]

The climate sensitivity to a doubling of CO2 with feedbacks may only be about 1°C, with humans contributing just 30% to the global warming since 1850. New research indicates the climate models that the Intergovernmental Panel on Climate Change (IPCC) rely upon for policy-making – and to claim humans are 100% responsible for the warming […]

Fuerteventura, one of the eight major Canary Islands, was not the “desert in the ocean” it is today throughout the Early to Middle Holocene. Scientists (Sánchez-Marco et al., 2026) have recovered the remains of several bird species known to reside at the edges of bodies of water (e.g., lagoons, lakes, rivers) with riparian vegetation and […]

The drivers of warming and glacier retreat in Antarctic climates are not aligned with a linearly-rising trend of atmospheric CO2. Scientists (Park et al., 2026) have assessed that over the last four decades the patterns of air temperature, sea surface temperature, and glacier retreat near King George Island (just north of the northernmost tip of […]

Greenland’s ice mass losses have dramatically decelerated since 2012. According to a new study (Nilsson and Gardner, 2026), from 1992-2023 the ice loss from Greenland ice sheet (GIS) and peripheral glaciers has added a total of only 1.1 cm (11 mm) to global sea levels. This is a sea level contribution rate equivalent of just […]

Because cold temperatures are so much more dangerous to human health than warmth, a modest 0.5°C warming could save over 10,000 lives per year in the US. A new study indicates that from 2000 to 2020 there were 6,129 annual deaths attributable to excess summer heat across 1,514 US counties (representing 91% of the United […]

Natural changes in cloud albedo, absorbed shortwave forcing (ASW), and solar activity (TSI, total solar irradiance) are “the dominant factors driving climate change.” Dai Ato, an independent researcher from Japan, has completed a comprehensive regression analysis (Ato, 2026) using key climate variables and published the results in the Science of Climate Change journal. Using widely […]

A new sea surface temperature (SST) reconstruction (Pan et al., 2026) uses mollusc fossil evidence to affirm southern Australia’s (Yorke Peninsula) SSTs were 4°C warmer than today (23°C versus 19°C) during both the mid-Holocene (MH, 8000 to 5000 years ago) and Last Interglacial (LIG, 125,000 to 116,000 years ago). Both the MH and LIG had […]

Solway Firth (UK) relative sea levels were 3.25 – 4 m higher than today from ~7000 to 5500 years ago before declining to present over the last few millennia (Hanan et al., 2026). The reconstruction coring sites were located up to ~3 km inland from the modern coast. New research also indicates Western Scotland’s relative […]
