August 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through August 2014 and HADCRUT4 and NCDC through July 2014—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through August 2014.

GISS Tweaks the Short-Term Global Temperature Trend Upwards


GISS released its August 2014 global surface temperature data today. As I was preparing the graphs for the August 2014 s4urface and lower troposphere temperature update, I noticed a sizeable jump in the short-term trend in the GISS data. (I’ll try to post the full update this evening.)  The August GISS LOTI value is higher than July, but it should not have had that much of an effect on the trend for the period of January 1998 to present. Not too surprisingly, much of the increase in trend was caused by adjustments to data from 2000 to 2013.

Quicky ENSO Update – September 15, 2014

Weekly NINO3.4 sea surface temperature anomalies (week of September 10) are back above the +0.5 deg C threshold of an El Niño. NINO1+2 sea surface temperature anomalies have dropped recently, but they should rise again as the new downwelling (warm) Rossby wave makes its way east and the warm water is drawn to the surface.

Data Reveal Florida Keys Sea Surface Temperatures Haven’t Warmed in 80+ Years*

*Based on the Linear Trend

A new study funded by the US Geological Survey (USGS) was introduced with the USGS press release Ocean Warming Affecting Florida Reefs – Increased Temperatures Spell Trouble for Corals.  The press release was included in yesterday’s post Claim: Ocean Warming Affecting Florida Reefs at WattsUpWithThat.  The study compares sea surface temperatures from a century ago to recent values, see Figure 1, as measured at lighthouses in the Florida Keys, but it fails to illustrate or discuss that temperatures reached similar levels during the mid-20th Century…or the fact that sea surface temperatures for that part of the Florida Keys show no warming in 80+ years.

August 2014 Sea Surface Temperature (SST) Anomaly Update


Monthly global sea surface temperature anomalies for August are well above the anomaly reached at the peak of the 1997/98 El Niño.

01 Global SSTa

(1) Global Sea Surface Temperature Anomalies

Monthly Change = +0.066 deg C


We discussed the reasons for these recently elevated sea surface temperatures in the post On The Recent Record-High Global Sea Surface Temperatures – The Wheres and Whys. Continue reading

The 2014 15 El Niño – Part 16 – September 2014 Update – Still Seeing Mixed Signals

(Oops.  Fixed a typo in the title.  This is Part 16.)

This post provides an update on the progress of the evolution of the 2014/15 El Niño (assuming there will be one) with data through the end of August 2014. The post is similar in layout to the past updates:  May, June, July and August.  The post includes 3 large gif animations and 15 illustrations so the post might take a few moments to load on your browser.  Please click on the illustrations and animations to enlarge them.

Just When You Thought It Couldn’t Possibly Get Any Sleazier, the Return of Climate Porn, WMO Style

Plus Obama’s Name-and-Shame Deal in a Different Light

Climate Porn is the title of a February 21, 2007 article in Cosmos Magazine authored by Tom Lowe.  He writes:

By doing what they do best, the media have taken hold of the climate change debate and placed it firmly in the public and political psyche. However, its predominantly gloomy spin does not appear to have had a significant affect on our day-to-day behaviour; for the majority of people it’s business as usual.

The alarming way in which climate change is presented to the public was referred to recently by a leading U.K. think-tank as ‘climate porn’. It has been described as unreliable at best and counter-productive at worst.

There are a number of papers on the counterproductive effects of promoting climate-related agendas with climate porn.  Continue reading

The WMO’s Macabre Climate Fiction

Bob Tisdale:

The WMO appears very happy to destroy their own credibility…with meteorologists from around the globe assisting with the WMO’s suicide of believability. This is remarkably idiotic. [Thanks, Donna.]

Originally posted on NoFrakkingConsensus:

Rather than persuading us with reason and logic, the World Meteorological Organization is making stuff up.

As the Reuters news service reported yesterday, the United Nations has launched a new public relations campaign. This is an attempt to call attention to yet another climate meeting, scheduled for the 23rd of this month, at the UN’s headquarters in New York.

The meeting is by invitation only. As per usual, green activist groups (aka “civil society”) have been invited, but the public will be kept out.

Mixed up in all of this is the World Meteorological Organization (WMO). Although its name suggests a responsible, professional entity, the WMO is actually a UN body. Evidently, it is also a plaything of UN officials. One need look no further than this PR campaign for evidence of the WMO’s lack of independence and integrity.


On the WMO’s YouTube channel we can…

Baseless Alarmism: Global Warming’s Impact on Gulf of Maine Driving Away Lobsters and Fish

The supposed impact of global warming on the Gulf of Maine over the past decade has hit a multitude of media outlets.  Example: take Weather.com’s article Global Warming Is Changing the Gulf of Maine, Imperiling Its Lobster, Fish Catch.  According to the article, Gulf of Maine temperatures were marching along with the global average from 1982 to 2004, but then over the past decade, starting in 2004, the Gulf of Maine began warming at a rate that was 10 times faster than the previous rate.

So let’s take a look at the sea surface temperature data for the Gulf of Maine, and see what story they have to tell.

Alarmism Warning – Preliminary Monthly Global Sea Surface Temperatures at Record High Levels

Preliminary Note:  An “alarmism warning” indicates alarmism is imminent.  On the other hand, an “alarmism watch” indicates alarmism might occur, but that’s all the time.

We’re not just talking a record high for the month of August…we’re talking a record high for any month during the satellite era.  I suspect our alarmist friends will be making all sorts of claims about attribution even though climate models still almost double the observed rate of ocean surface warming during the satellite era.
