A Different Perspective of Global Warming
I was preparing a few graphs for a chapter of my upcoming book (current working title An Illustrated Guide to Global Warming and Skepticism), and I thought readers here would…
The 2014/15 El Niño – Part 6 – What’s All The Hubbub About?…
…or Introductions to the Impacts of El Niños on Global Weather Patterns and to the Long-Term Effects of Strong El Niño Events on Global Surface Temperatures Since the first of…
On the Differences and Similarities between Global Surface Temperature and Lower Troposphere Temperature Anomaly Datasets
UPDATE: See the correction at the end of the post, which pertained to the discussion of the trend maps in Figures 13 and 14. I’ve crossed out the paragraph between…
March 2014 Global Surface (Land+Ocean) Temperature Anomaly Update
INITIAL QUESTION Once upon a time, the NCDC published its monthly global land+ocean surface temperature anomaly data around the 15th of the month. They have recently relaxed the dates of…
The 2014/15 El Niño – Part 5 – The Relationship Between the PDO and ENSO
UPDATE: I’ve added NOAA’s description of the PDO index toward the end of the post, before the closing. # # # During the earlier discussions of the upcoming El Niño…
The 2014/15 El Niño – Part 4 – Early Evolution – Comparison with Other Satellite-Era El Niños
In the preceding post, we looked at the evolution of the weekly sea surface temperature anomalies in two regions of the equatorial Pacific (NINO3.4 and NINO1+2), comparing the data so…
2014/15 El Niño – Part 3 – Early Evolution – Comparison with 1982/83 & 1997/98 El Niño Events
Comparisons are still being made of the 1997/98 El Niño with the El Niño forming this year. So I thought we should compare the weekly sea surface temperature anomalies for…
The 2014/15 El Niño – Part 2 – The Alarmist Misinformation (BS) Begins
I knew it wouldn’t take long. The 2014/15 El Niño has yet to form and there’s already a well-commented blog post about it that spreads more speculative nonsense than one…
The 2014/15 El Niño – Part 1 – The Initial Processes of the El Niño
The title of the post, of course, assumes that an El Niño event will form this year and carry over into the next. This post is intended for persons new…
El Niño Residuals Cause the C-Shaped Warming Pattern in the Pacific
In the recent model-data comparison of satellite-era sea surface temperature anomalies—appropriately titled Maybe the IPCC’s Modelers Should Try to Simulate Earth’s Oceans—we compared trend maps of modeled and observed sea…
Maybe the IPCC’s Modelers Should Try to Simulate Earth’s Oceans
UPDATE (April 6, 2014): I’ve added a link to a follow-up post about the cause of the observed C-shaped warming pattern in the Pacific. # # # The climate models…
March ENSO Update – outlook suggests a moderately strong El Niño for the 2014/15 ENSO season
Just about all indicators are pointing to a moderately strong El Niño for the 2014/15 ENSO season. See the NOAA weekly ENSO update dated March 24, 2014. The subsurface temperature…
GISS LOTI & NCDC Global Temperature Data Drop in February 2014
This post will serve as February 2014 Global Surface (Land+Ocean) Temperature Anomaly Update First GISS: Global surface temperatures, as represented by the GISS Land-Ocean Temperature Index (LOTI) data, dropped about…
On Chylek et al (2014) – The Atlantic Multidecadal Oscillation as a Dominant Factor of Oceanic Influence on Climate
I was advised of a recent paper that studies the impact of the Atlantic Multidecadal Oscillation on global surface temperatures since 1900. (Thanks, Anthony.) The paper is Chylek et al.…
It Isn’t How Climate Scientists Communicated their Message; It’s the Message
Over the past few months, there have been a number of articles about how the climate science community could have presented their message differently, or responded differently, so that they…
An Odd Mix of Reality and Misinformation from the Climate Science Community on England et al. (2014)
In this post, we’ll discuss a recent article and blog post about the recently published England et al. (2014). This post includes portions of past posts and a number of…
El Niño and La Niña Basics: Introduction to the Pacific Trade Winds
[UPDATE: I corrected the dates in the title blocks of Figures 10 and 11. My thanks to blogger Bob.moe for finding the typos.] England et al. (2014) Recent intensification of…
Cowtan and Way (2013) Adjustments Exaggerate Climate Model Failings at the Poles and Do Little to Explain the Hiatus
We’ve already discussed Cowtan and Way’s infilling of HADCRUT4 data in the post On Cowtan and Way (2013) “Coverage bias in the HadCRUT4 temperature series and its impact on recent…
January 2014 Global Surface (Land+Ocean) Temperature Anomaly Update
Initial Notes: This post contains graphs of running trends in global surface temperature anomalies for periods of 13+ and 16+ years using GISS global (land+ocean) surface temperature data. They indicate…
