Skip to comments.Global ocean temperatures drop to coldest in 6 1/2 years

The temperature of the ocean has cooled 0.2 degrees C in the past few of years, and is now only 0.1 degrees C warmer than it was throughout much of 1944. This data set had been showing a general warming trend since the late 1970s, (as well as a warming trend from the 1910s through the mid 1940s) with the warmest time being recorded in the El Nino year of 1998.
Despite temperatures peaking in 1998, it's been reasonable to describe the temperature trend as continuing, since 1998 at the time was a flukishly hot spell. Since 1998, the "normal" trend line approached what had been flukishly warm.
The reversal to cooler temperatures is not yet long or strong enough to discredit global warming completely... by a long shot. However, global warming alarmists had been warning that global warming had dramatically accelerated in the past couple decades; although ocean temperatures had risen a mere degree over the last century, the alarmists had warned of an increasing rate of warming, or even an increasing rate of an increasing rate of warming, suggesting the next century could see temperatures increase by several degrees.
Although this data is still consistent with a long, gradual trend of increasing ocean temperatures, it is not consistent with any sudden accelerations in warming trends.
My source is a data table at the NOAA, which could not be linked to directly, since it is available over file transfer protocol (FTP), not hypertext transfer protocol (HTTP). This is the link: ftp://ftp.ncdc.noaa.gov/pub/data/anomalies/monthly.ocean.90S.90N.df_1901-2000mean.dat It may be accessed from the bottom of the page I linked to in the source field, under "The Monthly Global Ocean Temperature Anomalies (degrees C)." My source is purely the data; the web page from which I derived it has not been updated to reflect any updated data.
Report to rehab.
I never flounder around when it comes to puns............
Now ya’ll know that global warming can cause either warming or cooling, Right. I mean no matter what happens the global warming crowd is right. Do you understand? It’s important that you understand!
Moisture moving from sea to land is one way of transfering heat energy to land. Since the cooling trend is less pronounced on land, I’d see that as more likely to result from more rain on land, not less. But none such pattern could be established from a very short-term reversal in a trend.
BUT: I personally believe that a very slight trend in global warming was suppressed in the post-war boom by massive production of particulate pollution, which has been proven to cause aerosols (liquid droplets suspended in air), which have been proved to create clouds, which reflect heat. Indeed, the amount of light energy reaching the surface of the Earth has increased dramatically, commensurate with the recent-but-halted reduction of particluate pollution (mid 1970s through to late 1990s) and also commensurate with the recent surge in global temperatures (1978-1998). I suppose that more aerosols mean clouds can contain more moisture, and hence carry it overland better. If you reduce the aerosols, you increase the amount of moisture condensing on each particle, and you cause rain to occur closer to the source of the moisture, which is the ocean. But that’s just my reasoning; I haven’t seen anything in particular to validate it.
The Halibut is that neither do I.
Damn global warming again. It’s turning both our oceans and atmosphere into Arctic conditions.
The only thing I can figure out, the last guy who did the measurement must have peed in the water first.
Where are all the hurricanes this year
La Nina conditions in the Eastern Pacific seem to be strengthening.
What happened to global warming? If the Goreacle says something, it must be true.
Are you being sarcastic? I was trying to avoid lingo, and what you quote is a very clumsy wording. Or is “trend line” what you are calling lingo? It’s a lousy mix of lingo and hack wording, I suppose.
What about pools??
Illegal aliens cooling the oceans Americans won’t cool.
You want shriknage? I'll give you shrikage:
No, actually I meant “this data,” as in “all this spaghetti,” not as in “all these spaghetti.” It is considered proper to refer to a collection of data as data.
I was being sarcastic. I would not consider “flukishly warm” to be a useful scientific phrase. Also, it seems like the “normal” trend is approaching the abnormal or “flukish” range, which seems — shall we say — odd.
Actually, the impressive part is that you’re looking at data which include all liquid ocean parts, I believe. So, it’s including more of the Arctic, which is warmer than usual, and less of the Antarctic, which is colder.
