German flagship news magazine Der Spiegel reports here on new satellite measurements of Himalayan glaciers. Not long ago IPCC scientists, among them Prof. Hans-Joachim Schellnhuber and train engineer Dr. Rajendra Pachauri, claimed with grave tones that the Himalayan glaciers would disappear by 2030. Hat-tip: a NTZ reader. That, among other errors, fantasies and exaggerations, turned out […]

Not long ago, the IPCC got one on the knuckles for grossly exaggerating Himalayan glacial ice melt, preposterously claiming the glaciers there would be gone by 2035. Now it comes to light that the IPCC has also grossly exaggerated the importance of glaciers as a source of fresh water supply for populations. This is what […]

Ed Caryl has become a regular contributor here, and today he presents insights on the causes of glacial melt. Here he discusses how absorption of solar energy by soot and Black Carbon contribute significantly to glacial melting and that CO2 is a minor factor. Glaciers – The Dark Side. It’s Not the CO2 Carbon […]

Relative sea level change over the Holocene documents a much warmer past than today. Because it was so much warmer during the Early to Middle Holocene (~8000 to ~4000 years ago), there was significantly less water locked up on land (Greenland, Antarctica) in the form of ice sheets and glaciers. Instead, this water occupied ocean […]

A Warmer Past: Non-Hockey Stick Reconstructions Roy et al., 2023 Holocene air temperatures were reconstructed from δ18O measurements from the nearby Agassiz Ice Cap. The 25-yr mean annual air temperature record shows a rapid Early Holocene warming, with temperatures being 6–8°C warmer than today at 10,000 yr b2k followed by a gradual cooling to AD […]

Four new studies in prestigious journals show Antarctic ice shelf as stable as ever. Hat-tip: EIKE Klimaschau Andreasen et al (2023) finds net gain A study by Julia R. Andreasen and colleagues looked at the changes in ice shelves, Antarctic-wide, using MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data from 2009 to 2019. Image: Andreasen et […]

Solar forcing may have a 4 to 7 times greater effect on climate change than current climate models indicate, which may mean modern climate change is predominantly natural rather than anthropogenic. Anthropogenic global warming (AGW) attribution may be significantly dependent on the choice of dataset. Advocates of AGW may only use Total Solar Irradiance (TSI) […]

Proxy temperature records calibrated to closely align with current instrumental temperatures undermine the current “global boiling” narrative when extended to the 18th century. Per a new study, maximum latewood density (MXD) tree-ring data have been observed to strongly correlate (r=0.77) with the modern (1959-2016) maximum (July-Aug.) instrumental temperature record (Li et al., 2023). In other […]

Scientists have determined there is no measured data to “indicate thicker than present ice after 4ka” at a West Antarctic study site near the Thwaites “Doomsday” Glacier. Any ice melt observed today is thus “reversible”… and natural. The Thwaites, Pine Island, and Pope Glaciers in the Amundsen Sea region of West Antarctica are all situated […]

During the last interglacial (LIG) 127 to 119k years ago, when CO2 levels were said to be only 275 ppm, Greenland’s Camp Century surface was ice free, vegetated. Today this same site is buried under a 1.4 kilometers-high ice sheet. The Arctic was sea ice free during the LIG (Diamond et al., 2021). Image Source: […]

Since the early 1990s the conventional assumption, aligned with modeling, has been that a molecule of human CO2 emission stays in the atmosphere – its residence time – for centuries. This fits the anthropogenic global warming (AGW) narrative. But empirical evidence contradicts these model-based assumptions. Residence time is closer to 5-10 years. In Table 1 […]

More evidence emerges that modern rates of sea level rise are approximately 20-50 times slower than natural rising rates occurring during deglaciations. In tropical areas coral reef fossils form terraces, or flat surfaces bordered by ascending sloping surfaces. Terraces are formed at or near sea level, so their relative geological presence can be interpreted as […]
