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].
USA Today features warmist John Cook, Facebook advisor who claims: "One element of climate misinformation that seems to be particularly prominent on social media is culture war type posts that attempt to paint people concerned about climate change as belonging to some separate social group intent on impinging on people’s freedoms," Cook said. "This is a particularly damaging form of misinformation as it exacerbates public polarization on climate change, making progress more difficult."
Greenpeace co-founder Dr. Patrick Moore responds to USA Today: "We skeptics are responsible for the 'public polarization' about the climate? Who is using the word 'denier' as if we skeptics want to send the true believers to the gas chambers? They are the ones foaming at the mouth with doomsday language. We are basing our opinions and facts on historical data and sound science." ... "Since we began using fossil fuels and making cement, the long decline of CO2 over the millennia has miraculously been halted. There is no reason to believe that if we had not unintentionally reversed the downward trend in CO2 that all life on Earth would have been threatened with eventual extinction when CO2 fell below 150 ppm. We have returned a balance to the global carbon cycle. There is no reason to prevent this from continuing up to 800 ppm and beyond."
Larry Hamlin: NOAA published its global climate report for year end 2021 highlighting that its global temperature anomaly measurements showed 2021 being the sixth highest of its recorded measurements. NOAA’s global annual measurement for 2021 was 0.84 degrees C. ... NOAA has exaggerated the importance of both monthly and annual temperature anomaly changes with as small a difference as +0.01 degrees C as a basis for climbing “hottest temperature ever” hype as was done for the July 2021 temperature anomaly data even though the confidence level for this measurement is +/-0.19 degrees C as discussed in WUWT articles here and here. ...
In addition to NOAA’s global temperature anomaly decline since year end 2016, all other global temperature anomaly measurement systems used by climate scientists worldwide all show declining global temperature anomaly measurements during the period from 2016 through 2021 as shown in the graphs below for surface global temperature anomaly measurement systems from NASA GISS and UK Met Office and for satellite global temperature anomaly measurement systems from UAH and RSS respectively.
