This is the fourth month with the new format. I’ve replaced the smoothed curve with a horizontal line that represents the Current Value.
MONTHLY SEA SURFACE TEMPERATURE ANOMALY MAP
The following is a Global map of Reynolds OI.v2 Sea Surface Temperature (SST) anomalies for July 2016. It was downloaded from the KNMI Climate Explorer. The contour range was set to -2.5 to +2.5 deg C and the anomalies are referenced to the WMO-preferred period of 1981-2010.

MONTHLY GLOBAL OVERVIEW
Global Sea Surface Temperature anomalies made a slight downtick in July, a decrease of about +0.02 deg C. Surface temperature anomalies remained basically unchanged in the Northern Hemisphere, and for the Southern Hemisphere, there was a decline. Last month, the only ocean basins to show a noticeable cooling were the South Pacific and Indian Oceans. The El Niño peaked in November, and the global sea surface temperature response to the El Niño peaked as well, about 2 months later in January 2016. Continue reading
I’ve left comments open. I’ll try to moderate them at least once per day.
During the hurricane season, I’ll be adding the sea surface temperatures and anomalies of the Main Development Region of hurricane development in the North Atlantic to the Monthly Sea Surface Temperature Updates. This post will serve as a reference.
The Main Development Region of the North Atlantic (10N-20N, 80W-20W) is where hurricanes tend to form, although they can develop outside that region. See the National Hurricane Center Tropical Cyclone Climatology webpage, specifically the maps of their origins by 10-day periods. And the hurricane season runs from June 1st through November 30th.

This post provides updates of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS and NCEI (formerly NCDC) through June 2016 and HADCRUT4 through May 2016—and of the two suppliers of satellite-based lower troposphere temperature composites (RSS and UAH) through June 2016. It also includes a few model-data comparisons. Continue reading
A quick ENSO update.
Meteorological agencies like NOAA use the sea surface temperature anomalies of the NINO3.4 region (5S-5N, 170W-120W) of the equatorial Pacific to determine if the tropical Pacific is experiencing El Niño, La Niña or ENSO neutral (not El Niño, not La Niña) conditions. Other agencies use the sea surface temperature data for the NINO3 region (5S-5N, 150W-90W). See the map on the NOAA webpage here for those locations.
Based NOAA’s weekly data for the NINO3.4 and NINO3 regions (data here), during the week centered on July 13, 2016, the sea surface temperature anomalies for both regions dropped to -0.6 deg C, which is a tick below the -0.5 deg C threshold of La Niña conditions. See Figures 1 and 2. Continue reading

THREE MAPS ILLUSTRATING SIMILAR GLOBAL SURFACE TEMPERATURE CHANGES OVER DIFFERENT 30-YEAR PERIODS
The GISS map-making webpage allows users to create global maps of surface temperature anomalies for specific time periods or to create maps of the change in surface temperatures over user-defined time periods based on local linear trends.
My Figure 1 includes 3 maps from that webpage. They are color-coded to show where and by how much surface temperatures have changed around the globe over three different 30-year periods, based on the GISS Land-Ocean Temperature Index (LOTI) data. I’ve highlighted in red the respective global temperature changes in deg C. They’re basically the same at 0.48 deg C and 0.49 deg C. You’ll note that I’ve also blacked-out the time periods, because I’ve asked the question Which 30-Year Warming Period Is Recent?

This post is similar in format to In Honor of Secretary of State John Kerry’s Global Warming Publicity-Founded Visit to Greenland… As you’ll see, like Greenland, the consensus of the climate models used by the IPCC show that the models do not simulate the surface temperatures for the contiguous United States over any timeframe from 1861 to present. Continue reading
This post confirms what most of us suspect based on the history of global surface temperature data responses to strong El Niño events. That is, if global surface temperatures respond similarly to past strong El Niños, the 2016 values should be higher than 2015. Continue reading
This is a quick ENSO update.
NOAA’s weekly sea surface temperature anomaly data for the NINO regions (based on the original Reynolds OI.v2 data) are furnished on Mondays. Today’s update for the week centered on June 22, 2016 shows the sea surface temperature anomalies of the NINO3.4 region (5S-5N, 170W-120W), which NOAA uses to define El Niño and La Niña events and their strengths, are at -0.4 deg C…a tick above the -0.5 deg C threshold of La Niña conditions.
