«The range of pH and temperature that some organisms experience on a daily basis exceeds the changes we expect to see in the global ocean by the end of the century,» notes Rivest, an assistant professor at VIMS.

Whether that could happen again in 2015 remains to be seen, though the ocean has a strong temperature memory and doesn't respond to changes very quickly.

It's the ocean «These small global temperature increases of the last 25 years and over the last century are likely natural changes that the globe has seen many times in the past.

[Response: You fail to see that ocean temperatures, satellite measurements, glacier melting, Arctic ice retreat, changes in phenology are all consistent with a warming planet.

I particularly enjoyed the slides that, when combined (1) provided an overview of hotter and cooler CO2 molecules as it relates to how they are seen from outer space and from profile — because this will make it easier for me to explain this process to others; (2) walked through the volcanic and solar activity vs assigning importance to CO2 changes — because this another way to help make it clearer, too, but in another way; (3) discussed CO2 induced warming and ocean rise vs different choices we might make — because this helps point out why every day's delay matters; and (4) showed Figure 1 from William Nordhaus» «Strategies for Control of Carbon Dioxide» and then super-imposed upon that the global mean temperature in colors showing pre-paper and post-paper periods — because this helps to show just how far back it was possible to make reasoned projections without the aid of a more nuanced and modern understanding.

I also used my implementation to break up a quick land response from a slow ocean response to see if the change in sign of the derived temperature derivative coming at a place where it is not intersecting the instantaneous temperature might be explained by the derived temperature being an average.

We have only begun to see the change in temperature and climate caused by the amount of CO2 that we have already added to the atmosphere (+38 %), and it will continue to change until the ocean - atmosphere climate system fully responds to that addition.

McIntyre has a new post where he tries to rescue the previous «projections» — but he confuses the changes in HadSST (ocean temperatures, which he is plotting) and the changes in HadCRUT3 (the global surface air temperature anomaly) which is what his projection was for (as can be seen in the figures in the main post).

I clearly see that the change in surface temperature and TOA radiative forcing simulated by the model depends upon the model complexity, for example, how the ocean circulations are represented.

A new study released Friday in the journal Science Advances helps clear up a bit of the mystery, by showing that man - made climate change is responsible for most of the change seen in ocean surface temperatures near the equator across Asia, which in turn affect regional rainfall patterns including the Indian monsoon.

Here's a clue — a tendency toward a more frequent La Nina state, driven specifically by increasing GH gas concentrations (and similar to conditions in the mid-Pliocene), may provide some modulation of tropospheric temperature spikes, but that energy will be advected somewhere (the idea of homogenous dispersion throughout the ocean is absurd), and that somewhere is exactly where we are seeing the biggest changes in the climate right now — the Arctic.

Pershing said that ocean temperatures in the Gulf may start to level off, but factoring in the rate of current carbon emissions, the Gulf of Maine could see a 5 to 7 degree change over the next 100 years.

The Atlantic Multidecadal Oscillation (AMO) is a naturally occurring pattern of sea surface temperature change that is seen in the North Atlantic Ocean on decadal timescales and affects weather and climate.

WASHINGTON — A sobering new report warns that the oceans face a «fundamental and irreversible ecological transformation» not seen in millions of years as greenhouse gases and climate change already have affected temperature, acidity, sea and oxygen levels, the food chain and possibly major currents that could alter global weather.

Recent changes in Pacific Ocean temperatures have been comparable to the decline seen at the end of the 1998 El Niño, although temperatures remain warmer than at the end of the most recent El Niño in 2010.

To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).

This time period is too short to signify a change in the warming trend, as climate trends are measured over periods of decades, not years.12, 29,30,31,32 Such decade - long slowdowns or even reversals in trend have occurred before in the global instrumental record (for example, 1900 - 1910 and 1940 - 1950; see Figure 2.2), including three decade - long periods since 1970, each followed by a sharp temperature rise.33 Nonetheless, satellite and ocean observations indicate that the Earth - atmosphere climate system has continued to gain heat energy.34

Thus what you see as wiggles in the increase per year is the direct result of temperature changes in ocean surface and vegetation (for the latter, precipitation also plays a role).

This changes the ocean temperature profile in the ways seen.

If we regress the annual rate of CO2 change against temperature, we are likely to see a significant short term temperature effect as warming reduces the solubility of CO2 in the surface ocean layers (with effects on terrestrial sinks as well).

Uncertainty in these projections due to potential future climate change effects on the ocean carbon cycle (mainly through changes in temperature, ocean stratification and marine biological production and re-mineralization; see Box 7.3) are small compared to the direct effect of rising atmospheric CO2 from anthropogenic emissions.

The observed patterns of surface warming, temperature changes through the atmosphere, increases in ocean heat content, increases in atmospheric moisture, sea level rise, and increased melting of land and sea ice also match the patterns scientists expect to see due to rising levels of CO2 and other human - induced changes (see Question 5).

The models (and there are many) have numerous common behaviours — they all cool following a big volcanic eruption, like that at Mount Pinatubo in 1991; they all warm as levels of greenhouse gases are increased; they show the same relationships connecting water vapour and temperature that we see in observations; and they can quantify how the giant lakes left over from the Ice Age may have caused a rapid cooling across the North Atlantic as they drained and changed ocean circulation patterns.
