The first is to emphasize your point that degassing of CO2 from the oceans is not simply a matter of warmer water reducing CO2 solubility, and that important additional factors include changes in wind patterns, reduction in sea ice cover to reveal a larger surface for gas escape, and upwelling of CO2 from depths consequent to the changing climate patterns.

He also pointed out that the new sea level would drastically change the place where salt water and fresh water meet in the California Delta area, causing havoc to all sorts of things (the environment, water supplies, people living in that vast area, and etc.).

Note that this sampling noise in the tide gauge data most likely comes from the water sloshing around in the ocean under the influence of winds etc., which looks like sea - level change if you only have a very limited number of measurement points, although this process can not actually change the true global - mean sea level.

Even in the absence of huge amounts of carbon dioxide as a forcing mechanism, he said, there still appear to be trigger points that, once passed, can produce rapid warming through feedbacks such as changes in sea ice and the reflectivity of the Earth's surface.

As the authors point out, even if the whole story comes down to precipitation changes which favor ablation, the persistence of these conditions throughout the 20th century still might be an indirect effect of global warming, via the remote effect of sea surface temperature on atmospheric circulation.

On Wednesday an interesting paper (Thompson et al) was published in Nature, pointing to a clear artifact in the sea surface temperatures in 1945 and associating it with the changing mix of fleets and measurement techniques at the end of World War II.

The freezing point of salt water varies strongly with the salinity which changes as the ice underneath melts and freshens the sea.

In my briefings to the Association of Small Island States in Bali, the 41 Island Nations of the Caribbean, Pacific, and Indian Ocean (and later circulated to all member states), I pointed out that IPCC had seriously and systematically UNDERESTIMATED the extent of climate change, showing that the sensitivity of temperature and sea level to CO2 clearly shown by the past climate record in coral reefs, ice cores, and deep sea sediments is orders of magnitude higher than IPCC's models.

Of course, there are quite a few experts in climate science and policy who warn that debating whether the research pointing to a disruptive human climate influence is, or is not, settled is a complete distraction from the reality that the basics are not in dispute (more CO2 = warming world = rising seas and lots of changing climate patternsOf course, there are quite a few experts in climate science and policy who warn that debating whether the research pointing to a disruptive human climate influence is, or is not, settled is a complete distraction from the reality that the basics are not in dispute (more CO2 = warming world = rising seas and lots of changing climate patternsof changing climate patterns).

But as a starting point, I'll propose now — and I'll change this if they disagree — the names of some leading scientists in this field who would NOT say there is sufficient evidence to conclude that human - caused global warming IS the main cause of increasing summer retreats of sea ice (although they would say there is strong likelihood that it will eventually dominate):

Alistair B McDonald: It seems that during last year's El Nino a tipping point was passed where the Antarctic sea ice extent, instead of slowly increasing year by year, changed to a mode where it is suddenly began to decrease.

Given all the independent lines of evidence pointing to average surface warming over the last few decades (satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more than very minor refinements to the current overall picture.

Updated, 3:10 p.m. Using climate models and observations, a fascinating study in this week's issue of Nature Climate Change points to a marked recent warming of the Atlantic Ocean as a powerful shaper of a host of notable changes in climate and ocean patterns in the last couple of decades — including Pacific wind, sea level and ocean patterns, the decade - plus hiatus in global warming and even California's deepening drought.

Moore et al 2015 found in Nature Climate Change that convection (the deep mixing of seawater closely linked to the AMOC) in the Greenland and Iceland Seas has weakened and is likely to exceed a critical point as global warming continues, where it will become limited in the depth reached.

The new paper suggests that the contribution from Greenland was on the low end of the prior estimates, but has little effect on the estimated total sea - level change, which points to a larger Antarctic source than the previous best estimate.

In what may prove to be a turning point for political action on climate change, a breathtaking new study casts extreme doubt about the near - term stability of global sea levels.

Arctic scientist Julienne Stroeve observed that the shrinking Arctic sea ice may have reached «a tipping point that could trigger a cascade of climate change reaching into Earth's temperate regions.»

Changes in the rate of sea level rise don't have to follow a parabola, since 1930 or any time point you care to name.

Ocean temperature change, however, reached a lower limit, probably because the freezing point of sea water put a restriction on how cold the deep ocean could get.

But even if you choose to doubt them, it is really the first seven that, combined, point to human activities as the only explanation of rising global temperatures since the Industrial Revolution, and the subsequent climate changes (such as ice melt and sea level rise) that have occurred due to this global warming.

The 2012 paper, World Ocean Heat Content and Thermosteric Sea Level change (0 - 2000 m), 1955 - 2010, by Levitus et al. points to the fact that over the study's span, to a depth of 2000 meters, the oceans have warmed by an average of 0.09 C.

Any rise or fall in absolute sea level will be a minor side effect of climate change if the chemical balance of the oceans reaches a tipping point.

These tipping points could be ice sheets on Greenland and Antarctica melting permanently, global food shortages and widespread crop failures with more extreme weather, rising ocean temperatures and acidity reaching triggering a crash in global coral reef ecosystems, and warming oceans push the release of methane from the sea floor, which could lead to runaway climate change, etc..

The criterion adopted here for having sufficiently removed the short term variability in order to get a stable estimation of the turning point (minimum sea - ice extent) of the annual cycle, was that there shall be only one change of direction.

The likelihood of the complete loss of Arctic summer sea ice by 2030, faster melting of the vast Greenland ice sheets, and the rapid and quickening thaw of permafrost regions indicate that the window for arresting climate change before tipping points are reached is rapidly closing.

Possible changes in sea water salinity, changing the freezing point of the water.

These include claiming that addressing climate change will keep the poor in «energy poverty»; citing the global warming «hiatus» or «pause» to dismiss concerns about climate change; pointing to changes in the climate hundreds or thousands of years ago to deny that the current warming is caused by humans; alleging that unmitigated climate change will be a good thing; disputing that climate change is accelerating sea level rise; and denying that climate change is making weather disasters more costly.
