Study 'reconstructs sea levels over the past 5.3 million years and shows that sea levels were higher than the present during almost every interglacial period over the past 5.3 million years...Thus, there is no evidence that sea level rise during the present interglacial is unprecedented, unnatural, unusual or any different from that which occurred in prior interglacials, or any evidence of influence by man on sea levels.'
Real Science reality check on Mann's claim: 'The tide gauge measurement of sea level at Lower Manhattan has been increasing linearly for over 150 years, with the peak slope around 1940. There isn’t one shred of evidence that CO2 emissions have affected sea level in New York, much less raised sea level by one foot. His claim has zero scientific basis'
Nye on Fox Business - 'The Independents': 'The extra heat in the atmosphere is changing weather patterns in surprising ways...The ocean will get bigger...and sea level will rise.' -- 'It's the speed that it is happening...What is the cost of having to move lower Manhattan?...3 or 4 feet, a meter (of ocean rise), you going to have to move a lot of lower Manhattan.' -- 'Would it be good if U.S. were the producer of the best solar panels, the best wind turbines?'
Study 'challenges the widely accepted value of global sea level rise for the 20th century' and finds sea levels rose in the southern hemisphere at only about half the rate of the northern hemisphere. According to the authors, sea levels rose only 7.9 inches in the northern hemisphere and 4.3 inches over the entire 20th century. This implies relative sea level change is primarily a localized phenomenon related to subsidence or post-glacial rebound [land height changes] rather than melting ice or steric sea level changes [thermal expansion from warming].
CNN: The Arctic Ocean has been warming since the onset of the 20th century, decades earlier than instrument observations would suggest, according to new research. The study, published Wednesday in the journal Science Advances, found that the expansion of warm Atlantic Ocean water flowing into the Arctic, a phenomenon known as "Atlantification," has caused Arctic water temperature in the region studiedtoincrease by around 2 degrees Celsius since 1900.
Francesco Muschitiello, an author on the study and assistant professor of geography at the University of Cambridge, said the findings were worrisome because the early warming suggests there might be a flaw in the models scientists use to predict how the climate will change. "The reconstructions suggest a substantial increase in the Atlantic Ocean heat and salt transport into the Nordic Sea at the beginning of the 20th century, which is not well simulated by (climate models)," Rong Zhang, a senior scientist at NOAA's Geophysical Fluid Dynamics Laboratory, who was not involved with the study, told CNN. "It's important to understand the cause of this rapid Atlantification, as well as the discrepancies between the model simulations and the reconstructions."
Scott Adams: "Fake News Play of the Year: CNN posts an article that debunks human-caused climate change (or at least the models), so they do it on Thanksgiving so no one notices and give it a misleading framing to conceal it."
