Jason and the Argo Notes

Guest Post by Willis Eschenbach Like Jason, I proceed into the unknown with my look at the Argo data, and will post random notes as I voyage. Come, my friends,…

UAH global Temperature for December – no change

UAH Global Temperature Update for Dec. 2011: +0.13 deg. C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly for December, 2011 remained about the same November, +0.13…

SST's cooler now than in the Medieval Warming Period

From “The Hockey Schtick“, some inconvenient truth that breaks Mann’s already broken hockey stick into even smaller pieces. A new paper finds significant cooling of Atlantic Ocean over past millennium,…

Tisdale on Climate Models Confirming Or Contradicting AGW

Part 2 – Do Observations and Climate Models Confirm Or Contradict The Hypothesis of Anthropogenic Global Warming? Guest Post by Bob Tisdale OVERVIEW This is the second part of a two-part…

Shades of Foster Grant

Tamino Misses The Point And Attempts To Distract His Readers By Bob Tisdale The obvious intent of my recent post “17-Year And 30-Year Trends In Sea Surface Temperature Anomalies: The Differences…

Santer's "17 years needed for a sign of climate change" compared against the IPCC models

I recently covered a press release from Dr. Ben Santer where it was claimed that: In order to separate human-caused global warming from the “noise” of purely natural climate fluctuations,…

Tisdale on model initialization in wake of the leaked IPCC draft

Should Climate Models Be Initialized To Replicate The Multidecadal Variability Of The Instrument Temperature Record During The 20th Century? Guest post by Bob Tisdale The coupled climate models used to hindcast…

The Texas ENSO Bassmaster Classic

A bit of a tiff developed over at Dr. Roger Pielke’s place over disagreements on the recent Texas heatwave being attributed to AGW or to ENSO. Bob Tisdale has something…

An Initial Look At The Hindcasts Of The NCAR CCSM4 Coupled Climate Model

Guest post by Bob Tisdale OVERVIEW This post compares the instrument observations of three global temperature anomaly datasets (NINO3, Global, and North Atlantic “Plus”) to the hindcasts of the NCAR…

Montana's new big sky discovery – El Niño casts a wide net

From Montana State University  and the “weather is not climate” department: Montana State researcher discovers link between Montana weather, ocean near Peru BOZEMAN, Mont. – A Montana State University researcher…

What do sea measurements reveal about Earth's temperature trend?

From the AGU highlights Despite the fact that average temperatures on land have been increasing from year to year, globally averaged surface temperatures from 2000 to 2010 have shown only…

Yet Even More Discussions About The Pacific Decadal Oscillation (PDO)

Guest post by Bob Tisdale INTRODUCTION I’ve written numerous posts that describe the Pacific Decadal Oscillation (PDO), what the PDO represents, and, just as important, what it does not represent.…

El Niño – a global warming survivor

From the AGU Weekly highlights: El Niño–Southern Oscillation variability persisted in warmer world Changes in the distribution of sea surface temperature associated with the El Niño–Southern Oscillation (ENSO) cause significant…

UAH global temperature anomaly – up in April

As La Niña fades, this is not surprising. Dr. Roy Spencer is back at work and reports the new lower troposphere number. Note also the global sea surface temperature graph…

ENSO report and forecast

  Summary: La Niña conditions continued across the equatorial Pacific. The magnitude of negative sea surface temperature anomalies continued to decrease across the Pacific Ocean. A transition to ENSO-neutral conditions…

Removing The Effects of Natural Variables – Multiple Linear Regression-Based or “Eyeballed” Scaling Factors

Guest post by Bob Tisdale This is the second of a series of follow-up posts to Can Most Of The Rise In The Satellite-Era Surface Temperatures Be Explained Without Anthropogenic…

UAH and UHI

Note: clearly satellites can see urban heat, as demonstrated by this recent paper unveiled at the 2010 AGU meeting by NASA. See: Satellites Image the Urban Heat Islands in the Northeast.…
