Alarmists Find New Excuse: Sea Levels Aren’t Rising Because ‘Ocean Bottom Deformation’

Scientists in the Netherlands have found a new excuse as to why sea levels are stubbornly refusing to rise in line with Al Gore’s doomsday predictions: “ocean bottom deformation.”
Apparently, they claim in a study by Thomas Frederikse et al, the weight of the extra water caused by all those melting glaciers and icecaps is so great that it is causing the sea bed to sink.

Their paper – titled ‘Ocean Bottom Deformation Due To Present-Day Mass Redistribution and Its Impact on Sea Level Observations’ – is published in Geophysical Research Letters.Here is the abstract:

Present-day mass redistribution increases the total ocean mass and, on average, causes the ocean bottom to subside elastically. Therefore, barystatic sea level rise is larger than the resulting global mean geocentric sea level rise, observed by satellite altimetry and GPS-corrected tide gauges. We use realistic estimates of mass redistribution from ice mass loss and land water storage to quantify the resulting ocean bottom deformation and its effect on global and regional ocean volume change estimates. Over 1993–2014, the resulting globally averaged geocentric sea level change is 8% smaller than the barystatic contribution. Over the altimetry domain, the difference is about 5%, and due to this effect, barystatic sea level rise will be underestimated by more than 0.1 mm/yr over 1993–2014. Regional differences are often larger: up to 1 mm/yr over the Arctic Ocean and 0.4 mm/yr in the South Pacific. Ocean bottom deformation should be considered when regional sea level changes are observed in a geocentric reference frame.

What this means is that seas are expanding much faster than is shown either by satellite altimetry or tide gauges. We just can’t see it because it’s happening, unnoticed, on the deep sea beds.

Climate Alarmists Finally Admit ‘We Were Wrong About Global Warming’

Climate alarmists have finally admitted that they’ve got it wrong on global warming.

This is the inescapable conclusion of a landmark paper, published in Nature Geoscience, which finally admits that the computer models have overstated the impact of carbon dioxide on climate and that the planet is warming more slowly than predicted.

The paper – titled Emission budgets and pathways consistent with limiting warming to 1.5°C –  concedes that it is now almost impossible that the doomsday predictions made in the last IPCC Assessment Report of 1.5 degrees C warming above pre-industrial levels by 2022 will come true.

In order for that to happen, temperatures would have to rise by a massive 0.5 degrees C in five years.

Since global mean temperatures rarely rise by even as much as 0.25 degrees C in a decade, that would mean the planet would have to do 20 years’ worth of extreme warming in the space of the next five years.
