Share this…FacebookTwitterThe 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 […]

Share this…FacebookTwitterThe 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 […]

Share this…FacebookTwitterA 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 […]

Share this…FacebookTwitterSeveral 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 […]

Share this…FacebookTwitterA 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 […]

Share this…FacebookTwitterSince 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 […]

Share this…FacebookTwitterGlobal sea surface temperatures have only been warming at a rate of about 0.06°C per decade since 1950. 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. Image Source: Dieng et al., 2017 The […]

New studies on the Atlantic current system assess the threshold between natural fluctuations and a climate change-driven evolution 25 April, 2022/Kiel, Germany. With a new publication in the scientific journal Nature Climate Change, researchers from Kiel once again contribute to the understanding of changes in the Atlantic […]

By Die kalte Sonne (Translated, edited by NoTricksZone) It was supposed to be a groundbreaking forecast, the early prediction of the weather phenomena El Niño and La Niña. Both affect the weather in very different ways. It would have been so nice to know a year […]

Share this…FacebookTwitter15% of modern global warming (ocean) can be attributed to geothermal heat fluxes through the sea floor that persistently heat the ocean. Evidence of more than 100,000 formerly or currently active volcanic vents permeate the Earth’s sea floor (Kelley, 2017). Active volcanoes spew 380°C sulfuric acid and “metal-laden acidic fluids” into the bottom waters […]

This step seems to be ignored for North Sea wind farms. Hat-tip: Die kalte Sonne. Wind farms are altering the North Sea Atmospheric wakes extending from the bottom to the […]

Share this…FacebookTwitterScientists say there’s just too little data available to suggest the Gulf Stream is slowing down, and there won’t be in the next five years. Die kalte Sonne looked at the Atlantic Meridional Overturning Circulation, the system of surface and deep currents in the Atlantic Ocean that – among other things – transports warmer […]
