Cause of Global Warming 'Hiatus' Found Deep In the Atlantic

vinces99 writes with news about a study that may account for a slowdown in air temperature rises. Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at the Earth's surface. More than a dozen theories have now been proposed for the so-called global warming hiatus, ranging from air pollution to volcanoes to sunspots. New research from the University of Washington shows the heat absent from the surface is plunging deep in the north and south Atlantic Ocean, and is part of a naturally occurring cycle. The study is published in Science. Subsurface ocean warming explains why global average air temperatures have flatlined since 1999, despite greenhouse gases trapping more solar heat at the Earth's surface. "Every week there's a new explanation of the hiatus," said corresponding author Ka-Kit Tung, a UW professor of applied mathematics and adjunct faculty member in atmospheric sciences. "Many of the earlier papers had necessarily focused on symptoms at the surface of the Earth, where we see many different and related phenomena. We looked at observations in the ocean to try to find the underlying cause." What they found is that a slow-moving current in the Atlantic, which carries heat between the two poles, sped up earlier this century to draw heat down almost a mile (1,500 meters). Most previous studies focused on shorter-term variability or particles that could block incoming sunlight, but they could not explain the massive amount of heat missing for more than a decade.

      The folks claiming that the "hiatus" is a denier hoax are not necessarily the same folks who published this paper.

      Furthermore, the argument is not that "hiatus" is a denier hoax - any fool can see temperature readings have been flat in most measured areas. The counter-argument is typically that the Earth is really big and that surface measurements alone do not necessarily represent the amount of heat absorbed by the atmosphere. Where all of that heat has been going was where the speculation has been, with the usual supposition being "the ocean" or "the poles".

      Because the Pacific ocean is thousands of kilometres wide, but only a couple of kilometres deep, changes in wind patterns can cover or uncover different layers of ocean waters.

      Actually, no. You're falling for the false-consensus effect. There are a whole lot of different "denier" opinions, but yours is not one of them. You are making false cause with people who actually think that you're a deluded global warming apologist. The people who are correctly labelled as deniers are those who actually deny that global warming is happening. Generally, they deny that the greenhouse effect exists, that CO2 is a greenhouse gas, or they deny that man is producing significant amounts of CO2.

      The people, like you, who claim that the models are overstating future warming and that unchecked global warming won't dangerous are luke-warmers, not deniers.

      Most of the models Ive read about show that human activity is only a tiny sliver compared to other factors, especially water vapor from evaporation.

      Let me explain a bit here. Water vapor is effectively constantly at saturation in the atmosphere, evaporation and precipitation keep it relatively well balanced. The major factor that determines how much water vapor is in the atmosphere is temperature. So, it's a feedback effect, water vapor amplifies the warming caused by other factors such as CO2 and Milankovitch cycles. Additionally, CO2 gets the lion's share of attention because it's a long lasting gas and we produce a lot of it. It will likely take centuries for CO2 levels to fall back to pre-industrial levels even if we cut emissions to zero right now. Other, more potent gases, tend to have half-lifes that are measured in years instead of decades or centuries and we produce orders of magnitude smallers amounts of them. So while CO2 is a relatively weak greenhouse gas, we produce a lot of it and some of the other gases, like water vapor, amplify it's effect.

    Science is about skepticism. Even climatologists that support the theory of man influenced climate change are constantly questioning the data, and looking at alternate conjectures. The very article referenced explicitly states that many of the theories that were presented to explain why global surface temperatures in the last decade did not track the apparent heat load global warming induced were inadequate, and the subject of further inquiry like the research cited. That's how Science works. But Science doesn't discover all the facts instantly and doesn't advance in convenient textbook chapters. It isn't skepticism that tries to characterize Science as just a bunch of random guesses, one after the other. That's just ignorance of Science. Science works by incremental and sometimes studdering progress forward. There are lots of things we know with certainty. We know carbon dioxide traps heat in Earth's lower atmosphere. We know human activities have dramatically increased the levels of CO2 in the atmosphere. The net result is an increased amount of heat absorbed by the Earth. What precisely happens to that heat in all of the complex thermal systems on Earth is still not well understood. But that doesn't mean the core principles are just random guesses. We're still discovering how 19th century chemistry works, but no one thinks that new chemistry discoveries mean chemistry is left-wing conspiracy.

    The history of scientific progress looks no different for any other subject than it looks for 21st century climatology. Our understanding of gravity, of the germ theory of infectious disease, of quantum mechanics all followed similar discovery and learning curves. The only difference is that general relativity and Schroedinger's equation aren't subjects politicians can effectively argue about.

    I think a lot of people, even some actual scientists, do not understand the role of skepticism in Science. There's a difference between scientific skepticism and peanut gallery skepticism. Scientific skepticism is healthy. When a scientist is skeptical of prevailing theories and conducts intellectually honest research aimed at probing that skepticism, that's always valuable. Science isn't a poll: if a scientific theory is correct, it will survive skeptical research. If its wrong, it will eventually be contradicted by the evidence. But when someone with no understanding of the facts or the research misinterprets the natural skepticism that is at the heart of scientific discovery by filtering it through their own "common sense" then they don't understand why science is successful overall, and really ought to shut up about it.

Theres a Nobel prize in this one if anyone ever did find such evidence!

    If this study is right then there will come a point when climate models are underestimating the warming again. The mechanism of this heat absorption is cyclical and eventually it will reverse leaving more heat in the atmosphere leading to rapid warming again. It's difficult if not impossible to put that into climate models partially because it's impossible (with our current knowledge) to know the timing of the switches in the cycle so models tend to just use the average which means sometimes their above the average and sometimes they're below.

    The abstract:

    A vacillating global heat sink at intermediate ocean depths is associated with different climate regimes of surface warming under anthropogenic forcing: The latter part of the 20th century saw rapid global warming as more heat stayed near the surface. In the 21st century, surface warming slowed as more heat moved into deeper oceans. In situ and reanalyzed data are used to trace the pathways of ocean heat uptake. In addition to the shallow La Niña–like patterns in the Pacific that were the previous focus, we found that the slowdown is mainly caused by heat transported to deeper layers in the Atlantic and the Southern oceans, initiated by a recurrent salinity anomaly in the subpolar North Atlantic. Cooling periods associated with the latter deeper heat-sequestration mechanism historically lasted 20 to 35 years.

    The question climate science deniers need to ask themselves is "If all of this heat is going into the ocean why hasn't it actually cooled rather than temperatures just sort of plateauing?" If all that heat is disappearing into the ocean and we're not actually cooling that means heat is still building up.

    The question of whether we're behind this - take two past events and see how much influence we might have:

    Remember the Icelandic volcano a few years back - in response to the volcanic ash, we grounded a lot of flights for a few days - and even in that time, we could measure how much the air changed - just by taking planes out of the picture for a few days.

    Secondly, if you think mankind's influence isn't large enough given the size of the planet - look back at climate records around the time Krakatoa blew up - that one mountain exploding had a measurable impact on temperature and weather for 5 years; so, if a _single_ mountain on one day can create that kind of change -- are you sure, all of our industries around the world together over the course of years CAN'T?

    What the planet is "too large for", is for us to do some quick and easy experiments to actually test our hypotheses quickly - so climate science does what it can mostly from observation and trying to identify as many factors as possible that DO have a measurable impact in order to MODEL what's going to happen and then wait and see how close these models correlate with what's happening.
