This is the third 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 June 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.

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.

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.

And Those Too-Cool Surface Temperatures Create Obvious Problems for Researchers
UPDATE: The closing has been revised.
The sea surface temperatures of the tropical North Atlantic are one of many factors that contribute to the development and maintenance of hurricanes. In fact, 26 deg C (about 79 deg F) is the sea surface temperature that’s typically quoted as the threshold for hurricanes.
This post provides model-data comparisons of the sea surface temperatures for the portion of the North Atlantic where hurricanes tend to breed, also known as the Main Development Region. I’ve used the coordinates of 10N-20N, 80W-20W for the Main Development Region. Continue reading
Alternate Title: Just in Case You Thought Sea Surface Temperatures around the Globe Responded Similarly to Strong El Niños
This is an update of the post here published back in March. It will illustrate quite clearly that the responses of ocean surface temperatures differ noticeably with strong El Niño events—those in 1997/98 and 2015/16. Continue reading
…A Few Model-Data Comparisons of Greenland Surface Air Temperatures
Mass losses from Greenland’s ice sheets have been one of the focuses of alarmists for decades. In fact, last week, U.S. Secretary of State John Kerry visited Greenland on a (boreal) summertime tour of parts of Greenland in an apparent political publicity stunt. See The Washington Post article John Kerry just visited the most stunning example of our changing climate by Chris Mooney. It’s chock full of alarmist babble. Great for a laugh. Why a laugh? Read on.
One of the principal contributing factors to the losses of Greenland’s ice sheets is surface temperature. So we’ll focus this model-data comparison on the surface air temperatures of Greenland. And speculation from the climate science community about Greenland surface temperatures and their impacts on ice sheet mass loss there and the contribution of those losses to sea level rise are based on climate models. As you’ll see, the consensus of the climate models used by the IPCC show the models cannot simulate Greenland’s surface temperatures over any timeframe from 1861 to present. Why then do people believe the model-based speculations about the future of Greenland surface temperatures, ice sheet losses and global sea levels? Because John Kerry wasted taxpayer dollars on a fossil-fuel-consuming trip to Greenland and then tweeted about it? Continue reading
This post provides an update of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS through May 2016 and HADCRUT4 and NCEI (formerly NCDC) through April 2016—and of the two suppliers of satellite-based lower troposphere temperature composites (RSS and UAH) through May 2016. It also includes a model-data comparison. Continue reading

MONTHLY GLOBAL OVERVIEW
Global Sea Surface Temperature anomalies made a downtick in May, a decrease of about -0.02 deg C. Surface temperature anomalies rose in the Northern Hemisphere, but that rise was more than countered by a decrease in the Southern Hemisphere. Last month, the ocean basins that showed warming were the North Atlantic, North Pacific and the Arctic and Southern 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
