They are ebooks in .pdf format:
- On Global warming and the Illusion of Control – Part 1 presents the basics and illusions behind the hypothesis of global warming and climate change,
- Who Turned on the Heat? is a comprehensive examination of The processes and long-term global-warming aftereffects of El Niños and La Niñas, which are the dominant weather events on Earth, and
- Climate Models Fail, as its title suggests is about the poor performance of climate models.

This post provides updates of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS through August 2016 and HADCRUT4 and NCEI (formerly NCDC) through July 2016—and of the two suppliers of satellite-based lower troposphere temperature composites (RSS and UAH) through August 2016. It also includes a few model-data comparisons. Continue reading
La Niña conditions are typically defined by NOAA as sea surface temperature anomalies less than or equal to -0.5 deg C for the NINO3.4 region of the east/central equatorial Pacific. The NINO3.4 sea surface temperature anomaly for the week of August 31, 2016 from NOAA’s Monthly Atmospheric and SST Indices webpage (data here) is -0.7 deg C, well into weak La Niña conditions.
Regardless of the existing (and strengthening) La Niña conditions, NOAA has canceled its La Niña Watch, which had been in effect since April. Continue reading
The Blob appears to be returning (reemerging) in the eastern extratropical North Pacific. See the map below and the data update toward the end of the post.
Has it coupled once again with the ridge of high pressure? If so, that’s not a good sign for precipitation in the western U.S. Continue reading
Suggested Disclaimer: Climate Model Outputs Have Been Manipulated By NOAA to Make Models Appear to Perform Well
This post introduces readers to a newly revised “product” from NOAA, called “Climate Explorer”, which is part of their U.S. Climate Resilience Toolkit. NOAA released this misleading product on July 27, 2016 and so far it has received little attention by the blogosphere and mainstream media.
That’s a good thing.
NOAA has manipulated the climate model outputs to make the models stored in the CMIP5 archive appear to perform well regionally on an absolute basis. Continue reading
This post provides updates of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS through July 2016 and HADCRUT4 and NCEI (formerly NCDC) through June 2016—and of the two suppliers of satellite-based lower troposphere temperature composites (RSS and UAH) through July 2016. It also includes a few model-data comparisons.
This is simply an update, but it includes a good amount of background information for those new to the datasets. Because it is an update, there are no overview and summary for this post. There are, however, summaries for the individual updates. So for those familiar with the datasets, simply fast-forward to the graphs and read the summaries under the heading of “Update”.

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.

(Global SST Anomaly = +0.35 deg C)
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
