The Pacific Ocean covers about one-third of the Earth’s surface. Much of it has been cooling in this era of “global” warming. New research indicates there has been “cooling of the Pacific sector on decadal timescales during 1940-2020,” including robust cooling reaching -0.4°C per decade from 2005-2019 (even “exceeding -0.9°C per decade during 2005-2010”). “…observations […]

According to a new study, coral proxy sea surface temperature (SST) evidence suggests the northern South China Sea (nSCS) naturally warmed and cooled at rates of 1 to 1.5°C per decade from about ~5300-5100 years ago. Image Source: Wu et al., 2026 In contrast, the nSCS temperature record has been flat to slightly declining in […]

Deglaciation periods, such as the one occurring from about 14,000 to 6000 years ago, are estimated to have had ocean heat uptake rates of 12,000-20,000 ZJ (zettajoules). This range of excess energy absorption is 20-30 times greater than the rate of global ocean heat uptake that exists today (Gebbie, 2021). During the Medieval Warm Period, […]

“…a distinct pattern of water vapor suppressing the [sea surface temperature] diurnal amplitudes at low latitudes” – Harris et al., 2025 Observations show morning-to-evening sea surface warming amplitudes can exceed 5°C. Water vapor (WV), the greenhouse gas (GHG) mostly responsible for Earth’s greenhouse effect, adds ~0.1°C warming to this 5°C diurnal change in the high […]

The data show flat trends in shortwave radiation, longwave radiation, and radiation balance for the global ocean since 1970 despite a 100 ppm increase in CO2. An unheralded 2025 study uses long-term observed cloud cover data over oceans to uncover trends in radiative fluxes from 1900 to 2020. Trends in the subtropics (15-40°N, 45-65°W) indicate […]

According to a recent presentation by climate scientist Dr. Ole Humlum published in Science of Climate Change: Real-world observations show both cooling and warming trends in the Arctic, Antarctic, and Tropical oceans since ARGO monitoring was introduced in 2004. Real-world observations show no trend in global precipitation since 1979. Real-world observations show global cloud cover […]

The Germany-based European Institute for Climate and Energy (EIKE) has posted its latest Klimaschau video, titled “Prähistorische Ozeanschichten als möglicher Faktor der Erwärmung (Prehistoric Ocean Layers as a Possible Factor in Warming): The new video highlights a study from Rutgers University published in Nature Geoscience. Researchers found that the rapid global warming phase at the […]

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 […]

Climate changes fostered by “unforced natural climate variability” may be more than an order of magnitude larger than the climate changes commonly attributed to anthropogenic forcing. In a new study, scientists have attempted to identify the mechanisms explaining Greenland’s many historical (~80,000-11,700 years ago) climate changes that amounted to 10-15°C “in a decade or two.” […]

“[T]he fraction of [fossil] fuel-related emissions still remaining in the air (about 23 ppm out of 425 ppm at the end of 2024) cannot have any climatic effect.” – Veyres et al., 2025 A few years ago Dr. Koutsoyiannis and colleagues used equations associated with the chemistry of temperature-driven organic respiration to demonstrate that, since […]

Fundamental assumptions in projections of alarming, CO2-induced global warming in the coming decades are undermined by a new long-term energy budget analysis. In a new study scientists have acknowledged the modeled assumptions forecasting nature’s response to the presumed human-driven radiative forcing of ocean heat uptake, thermal expansion, and sea level rise rates do not align […]

The idea that global warming could paradoxically shut down the Gulf Stream, plunging Europe into a new cold spell—a scenario popularized by the film The Day After Tomorrow—is a powerful narrative. However, the latest episode of Klimaschau (Issue 237) challenges these alarmist predictions, scrutinizing the scientific evidence and the methods behind the claims. The segment […]
