Share this… Facebook TwitterPer 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 […]

Share this… Facebook TwitterBy 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.

Share this… Facebook TwitterThe 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 […]

Share this… Facebook TwitterThe 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 […]

Share this… Facebook TwitterA 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 […]

Share this… Facebook TwitterSeveral 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 […]

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 […]

Share this… Facebook TwitterSince 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, […]

According to Dieng et al., 2017, global sea surface temperatures (SST) cooled slightly (-0.006°C/decade) from 2003 to 2013. This reduced the overall 1950-2014 warming rate to 0.059°C per decade.
