The Recent Westerly Wind Burst in the Western Equatorial Pacific Could Help to Strengthen the 2015/16 El Niño

The graphics at the NOAA GODAS website were running a few pentads (5-day periods) behind when I published the May 2015 ENSO Update.  They’re caught up now, and the Hovmoller diagram of the surface zonal wind stress along the equator, Figure 1, is showing another westerly wind burst during early May 2015 in the western equatorial Pacific.

2 Deg C Global-Warming Limit in the News – Recent Comments by James Hansen, Godfather of Climate Alarmism

The 2 deg C global warming limit, above pre-industrial temperatures, is back in the news.  That limit was first proposed in the 1970s by an economist, not a climate scientist, according to the article Two degrees: The history of climate change’s ‘speed limit’ at TheCarbonBrief.  Authors Mat Hope & Rosamund Pearce note: Continue reading

Wow! ECMWF Long-Term Weather Model Is Predicting a Super El Niño and I Mean Super

I was notified today of the rather remarkable plume of ENSO forecasts for 2015 from ECMWF (European Centre for Medium-Range Weather Forecasts).  See their System 4 ENSO region sea surface temperature anomaly forecast webpage here. Continue reading

April 2015 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update

This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through April 2015 and HADCRUT4 and NCDC through March 2015—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through April 2015. Continue reading

May 2015 ENSO Update – Australia’s BOM and the JMA Declare an El Niño and With Them Comes the Typical Nonsense from an Expert Source

This post provides an update of many of the ENSO-related variables we presented as part of the 2014-15 El Niño Series.  The reference years for comparison graphs in this post are 2009 and 2014, which are the development years of the last two El Niños.  I have not included animations in this post. In their place, I’ve compared present-day maps from the NOAA GODAS website to the same time in 2014. Continue reading

April 2015 Sea Surface Temperature (SST) Anomaly Update

INITIAL NOTES:  I’ve added a graph of the Blob sea surface temperature anomalies so we can keep track of them.  The format of the graphs has been revised, extending the x-axis to the year 2020 and eliminating to yearly vertical gridlines.  I’ll provide an El Niño update tomorrow or the next day.


The following is a Global map of Reynolds OI.v2 Sea Surface Temperature (SST) anomalies for April 2015.  It was downloaded from the KNMI Climate Explorer. The contour range was set to -2.5 to +2.5 deg C.

On the Pause in Global Sea Ice Anomalies

I just finished the illustrations and text for another chapter of my upcoming book. The latest was about sea ice data. I believe you’ll be interested in one of the topics from that chapter.  As noted in the title of the post, the topic is the “pause” in global sea ice extent anomalies. Continue reading

Stunning Photo Reveals How Vatican Learned to Spin Global Warming

Pope Francis’s entry into the political climate-change debate was welcomed by some, frowned on by others. A new photo reveals who taught the Pope the proper way to spin global warming. Continue reading
