IPCC models rooted in assumptions that we humans can and do control the Atlantic Ocean’s circulation with our daily-activity CO2 emissions have been wrong since the mid-1980s. Why should we still believe in them? The latest IPCC report continues to say it is “very likely” the Atlantic Meridional Ocean Circulation (AMOC), a fundamental climate parameter, […]

By Fritz Vahrenholt und Frank Bosse A look back at an article about the imminent “tipping point” of the Atlantic overturning circulation: At the end of July 2023 we had reported on an essay that thought to have identified the “tipping point” of the Atlantic overturning circulation (AMOC): Supposedly (most likely) it will be already […]

“The degree of one’s emotions varies inversely with one’s knowledge of the facts, the less you know the hotter you get.” – Bertrand Russell Per a new study, people who are less knowledgeable about the climate and environment are more likely to experience climate change anxiety (e.g., “I find myself crying because of climate change”) […]

Per a new study on the hydrological cycle’s role in climate change, today’s state-of-the-art climate models “assume the mean relative humidity at the ocean surface is constant.” They are also known to “assume unchanged wind conditions.” Even with this imaginary constancy, “uncertainties in modeling the hydrological cycle significantly [orders of magnitude, or more than 100-fold] […]

By Gabriel Oxenstierna We’ve had a La Niña for nearly three years. But now it has officially ended, and ENSO has moved into its neutral phase, the “La Nada”.[1] The La Niña event lasted three winters in a row, something that has only occurred twice before in modern times: 1973–1976 and 1998–2001. Both of these […]

The German Klimaschau here presents a new video, this one featuring a new study on the Antarctic Ice Shelf published in Nature Geoscience: Ice sheet “has grown” According to a University of Cambridge press release dated May 13, 2022, “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due […]

The Pacific Ocean is 5 to 6 km deep. New research indicates the bottom half (2 km to the bottom) of the Pacific has been robustly cooling since 1993. A new preprint details the “surprising” Pacific cooling pattern from two ocean heat content (OHC) datasets over the 1993-2017 period. Most OHC records only extend to […]

The accuracy of the long-term global instrumental temperature record – especially the data obtained before the 1970s – wholly rests on the assumption that sailors obtained precisely reliable temperature measurements as they pulled wooden or canvas buckets out of the water from ships at random depths, locations, and times of day. They didn’t. It has […]

A new study reports there has been a -0.3°C cooling in the Southern Ocean since 1982 per multiple observational data sets. The authors detail the “failure of CMIP5 models in simulating the observed SST cooling in the Southern Ocean.” The Southern Ocean is today about 1-2°C colder than it has been for nearly all of […]

Several new and recent studies have affirmed that the waters surrounding South America – from Peru to Chile to Argentina to Brazil – were several degrees warmer and sea levels multiple meters higher than today until the Little Ice Age centuries. A new study suggests ~4,000 to 5,000 years ago coastal Argentina’s sea surface temperatures […]

A new study indicates nearly all the Northern Hemisphere and Tropical warming in the last 40 years occurred by the late 1990s. CO2 has risen by about 50 ppm since 1998 (367 to 418 ppm). Interestingly, upper-air measurements of temperature from balloon-borne sensor radiosonde data, shown below in the image from a new study (Madonna […]

Since 2000 there has been a natural reduction in net air-sea fluxes at the same time there has been rapid warming in the Indian Ocean. This affirms anthropogenic surface forcing cannot explain the recent warming in at least half the global ocean. The Indian Ocean covers approximately 20% of the ocean surface, but this basin […]
