Analysis: Global Warming ‘Godfather’ James Hansen’s New Alarmist Study Has A Fatal Flaw
James Hansen, a former NASA scientist dubbed the “godfather” of global warming, has a new study out claiming future warming could be worse than predicted, with the world suffering through massive sea level rise and super storms.
Hansen’s global warming doomsday scenario suffers from one (well, at least one) major flaw: it depends on a slowdown of Atlantic overturning circulation, which transports warm water from the tropics to the North Atlantic where it warms the atmosphere.
Hansen and his co-authors list a “slowdown and eventual shutdown of the Atlantic overturning circulation with cooling of the North Atlantic region” as one of five impacts man-made global warming would have on the planet.
…
A new study debunks claims made by Hansen, Rahmstorf and Mann that man-made warming will slow the AMOC or even completely shut it down.
“Claims of strengthening or reducing of the AMOC are therefore pure speculation,” Aussie scientists wrote in their recently published paper.
The Aussie scientists specifically refuted the study by Rahmstorf and Mann claiming ice melt was slowing the AMOC based on climate models and proxy data. That study directly contradicted actual measurements of the AMOC taken by oceanographer Thomas Rossby of the University of Rhode Island.

…Claimed 3.2 Millimeters Per Year Sea Level Rise Seriously Challenged By Recently Published Scientific Papers!
Claimed 3.2 Millimeters Per Year Sea Level Rise Seriously Challenged By Recently Published Scientific Papers!
Challenged: 3.2 mm/year sea level rise since 1993 By guest author Kenneth Richard Source data studies indicate recent only 0.8 – 1.6 mm/year sea level rise. According to the IPCC (2013), sea levels rose at a rate of 1.7 mm/year (6.7 inches per century) for the 1901 to 2010 period, but 3.2 mm/year (12.6 inches per century) during the 18-year period between 1993 to 2010, a rate similar to that obtained from 1920 to 1950. If sea levels truly were rising at rates of 3.2 mm/year between 1993 and 2010 as the IPCC (2013) claims with high confidence, then the thermal and ablation sources for that sea level rise should at least somewhat closely add up to 3.2 mm/year for the same period. But if the sources for the sea level rise as determined by published studies only reach between 0.8 and 1.6 mm/year when added together – a quarter to half of the 3.2 mm/year claimed – then that suggests that there is something seriously questionable about the 3.2 mm/year sea level rise estimates for 1993 to 2010 obtained by satellite altimetry. What follows is an abridged list of recent papers showing that sea level rise estimations claimed by the IPCC are likely highly exaggerated. — http://www.climatechange2013.org/images/report/WG1AR5_Chapter13_FINAL.pdf „It is very likely that the global mean rate was 1.7 mm yr–1 between 1901 and 2010 for a total sea level rise of 0.19 m. Between 1993 and 2010, the rate was very likely higher at 3.2 mm yr–1; similarly high rates likely occurred between 1920 and 1950.“ — Problematically, in recent decades the source contribution estimates for recent decades from published studies add up to half (or less) of this claimed rate. According to recent estimates, the contribution to sea level rise from thermal expansion was 0.64 mm/yr (2.5 inches per century) for the period between 2005-2013 (Llovel et al., 2014, see below). The contribution from the Greenland (GIS) and Antarctic (AIS) ice sheets was 0.59 mm/yr (2.3 inches per century) for the 1992-2011 period (Shepherd et al., 2012). The contribution from global glaciers and ice caps that are not the GIS or AIS was 0.41 mm/yr (1.6 inches per century) for 2003-2010 (Jacob et al., 2012). — Llovel et al., 2014 http://www.nature.com/nclimate/journal/v4/n11/full/nclimate2387.html Over the entire water column, independent estimates of ocean warming yield …
CNN Warmist: ‘The question Trump can’t dodge in Florida’ – Global Warming! Warns rising seas could flood Trump properties
I plugged the addresses of a few luxury hotels bearing the Trump name into a handy tool developed to visualize the rise in sea levels that’s associated with global warming.
The Trump International Beach Resort, in Sunny Isles Beach, Florida, will sit on a slender island of land at 6 feet of sea-level rise, which the federal government says is possible this century.
It looks like Trump Hollywood, meanwhile, will be submerged at that point.
Leading Authority on Sea Levels Disputes Study Asserting Sea Level Rise Is Fastest in 27 Centuries
Sea Level Expert Rips Study Claiming Fastest Rise in 2800 years: Study ‘full of very bad violations of observational facts’
– global tide gauges show moderate mean rates– many key sites and test sites show little or no rise at all– nowhere do we find records of true “acceleration”– satellite altimetry show a mean rise of 0.5 ±0.1 mm/yr after back-callibration– past sea level oscillations have been faster & steeper that in the last century

Past Sea Level Rise Data ‘Adjusted’ Upward: NASA has ‘more than tripled sea level rise by simply altering the data’
…NYT: Forecast for Sea Level Rise By 2100 Scaled Back from max of 6 feet to 4 feet – But ‘reconstruction’ of sea levels over 28 centuries claim current rate is fastest rising
http://www.nytimes.com/2016/02/23/science/sea-level-rise-global-warming-climate-change.html?hp&action=click&pgtype=Homepage&clickSource=story-heading&module=first-column-region®ion=top-news&WT.nav=top-news&_r=0
Scientists reconstructed the level of the sea over time and confirmed that it is most likely rising faster than at any point in 28 centuries, with the rate of increase growing sharply over the past century — largely, they found, because of the warming that scientists have said is almost certainly caused by human emissions.
They also confirmed previous forecasts that if emissions were to continue at a high rate over the next few decades, the ocean could rise as much as three or four feet by 2100.
…
One of the authors of the new paper, Dr. Rahmstorf, had previously published estimates suggesting the sea could rise as much as five or six feet by 2100. But with the improved calculations from the new paper, his latest upper estimate is three to four feet.

Scientists say the recent climate agreement negotiated in Paris is not remotely ambitious enough to forestall a significant melting of Greenland and Antarctica, though if fully implemented, it may slow the pace somewhat.…
Sea Level Rise: ‘Just The Facts’: ‘Sea-level rise is not accelerating, & has not accelerated since 1920s’
With atmospheric CO2 at 0.040% by volume, globally averaged sea-level rise at the coasts is just under +1.5 mm/year.
When atmospheric CO2 was at 0.031% by volume, globally averaged sea-level rise at the coasts was just under +1.5 mm/year.
The difference is that climate alarmists think the current +1.5 mm/year is catastrophic and caused by human release of CO2, and the +1.5 mm/year 85 years ago was natural and inconsequential.
However, the similarity between the two numbers — the catastrophic 1.5 mm/yr and the inconsequential 1.5 mm/yr — has confused even some liberals into backing away from the One True Climate Faith. Even President Obama’s former Undersecretary for Science, Steven Koonin, has written that:
“Even though the human influence on climate was much smaller in the past, the models do not account for the fact that the rate of global sea-level rise 70 years ago was as large as what we observe today.”…
Pope Francis adviser calls on Florida pols to address ‘climate change’
http://www.bradenton.com/news/local/article61522002.html
MIAMI — Florida politicians have a duty to address the perils of climate change even if they don’t believe humans are hastening its grave consequences, Pope Francis’ chief adviser on climate change said in an interview with the Miami Herald before addressing a weekend conference on climate, nature and society at St. Thomas University law school.
Cardinal Peter Turkson said: “Anybody running for public office who sees the life of the people affected by climate-related disasters” needs to act.
That, he said, includes the state’s two Republican presidential contenders — former Gov. Jeb Bush and Sen. Marco Rubio — who remain skeptical of the science tying climate change to increased carbon emissions.
“You’ll not be shocked by this,” Turkson added. “I also know of a cardinal or two who don’t believe.”
