The 2014/15 El Niño Series Posts

The 2014/15 El Niño Series included numerous discussions about the basic processes that drive El Niño events, especially early on in the series.  This post only lists the titles of the posts but they give the general idea of the content.  I’ll link this one in future posts about the evolution in 2015.

North Pacific Update: The Blob’s Strengthening Suggests It’s Not Ready to Depart

This post provides an update of the unusual warming event in the sea surface temperatures of the eastern extratropical North Pacific…what is now regularly called “The Blob”.  It does not appear to be ready to depart anytime soon.  See the sea surface temperature anomaly map in Figure 1 for the location of The Blob.

U.S. House of Representatives Hearing on Obama’s UN Climate Pledge Today at 10AM Eastern

The United States House of Representatives Committee on Science, Space, and Technology are holding a hearing today starting at 10am (Eastern) titled The President’s UN Climate Pledge: Scientifically Justified or a New Tax on Americans?  The webpage with link to the webcast is here, and the charter for the hearing is here.

Judith Curry is one of the witnesses.  See her blog post here.

The other three witnesses are:

The Honorable Karen Harbert, President and CEO, Institute for 21st Century Energy, U.S. Chamber of Commerce; Former Assistant Secretary for Policy and International Affairs, U.S. Department of Energy

Mr. Jake Schmidt, Director, International Program, Natural Resources Defense Council

Dr. Margo Thorning, Senior Vice President and Chief Economist, American Council for Capital Formation

March 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 March 2015 and HADCRUT4 and NCDC through February 2015—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through March 2015.

Open Letter to U.S. Senators Ted Cruz, James Inhofe and Marco Rubio

UPDATE:  See the correction to the number of models under the heading of REDUNDANCY:  WHY ARE TAXPAYERS FUNDING 5 CLIMATE MODELS IN THE U.S.?

###

Date:  April 14, 2015

Subject: Questions about Climate Model-Based Science

From:  Bob Tisdale – Independent Climate Researcher

To: The Honorable Ted Cruz, James Inhofe and Marco Rubio

Dear Senators Cruz, Inhofe and Rubio:

I am writing you as chairs of the Subcommittee on Space, Science, and Competitiveness, of the Senate Environment and Public Works Committee, and of the Committee on Oceans, Atmosphere, Fisheries, and Coast Guard.  I am an independent researcher who studies global warming and climate change, and I am probably best known for my articles at the science weblog WattsUpWithThat, where I would be considered an investigative reporter.

I have a few very basic questions for you about climate model-based science.  They are: Continue reading

March 2015 Sea Surface Temperature (SST) Anomaly Update

INITIAL NOTE:  I’ll provide an update on the North Pacific blob soon.

MONTHLY SEA SURFACE TEMPERATURE ANOMALY MAP

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

NOAA ENSO Model Now Forecasting a Supercalifragilistic El Niño for 2015/16 Season

First: Congratulations to the teeny-tiny 2014/15 El Niño.  It’s now official. NOAA included it as an “official warm event” on their Oceanic NINO Index this week.

NOAA’s CFS.v2 model (dated April 9, 2015, source here) is now forecasting a strong El Niño for this upcoming ENSO season, or as blogger Alec, aka Daffy Duck called it, “a supercalifragilistic el nino” when he brought the forecast to my attention here.  See Figure 1.  That forecast is noticeably higher than the one that shows up on page 25 of the NOAA weekly ENSO update, which was dated April 4th.

The Vancouver Sun’s Video Interview with Freeman Dyson

The Vancouver Sun recently published a video interview with “Princeton University’s preeminent” theoretical physicist and mathematician Freeman Dyson, as part of their “Conversation that Matters” series hosted by Stuart McNish.  (Correction: Freeman Dyson is a professor emeritus of the Institute for Advanced Study, which is not affiliated with Princeton University. Thanks, Phil.)  If you don’t know who Freeman Dyson is, see his condensed biography here and detailed biography here.  Freeman Dyson is also skeptical of catastrophic CO2-driven global warming/climate change.

March 2015 ENSO Update – Will the 2014/15 El Niño Become the 2014/15/16 El Niño?

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

25 Years of Monitoring Global Temperatures from Satellites and an Interview with Christy and Spencer of UAH

It’s been 25 years since Spencer and Christy of the University of Alabama at Huntsvillle published their 1990 paper Precise Monitoring of Global Temperature Trends from Satellites.  The abstract reads (my boldface):

Passive microwave radiometry from satellites provides more precise atmospheric temperature information than that obtained from the relatively sparse distribution of thermometers over the earth’s surface. Accurate global atmospheric temperature estimates are needed for detection of possible greenhouse warming, evaluation of computer models of climate change, and for understanding important factors in the climate system. Analysis of the first 10 years (1979 to 1988) of satellite measurements of lower atmospheric temperature changes reveals a monthly precision of 0.01°C, large temperature variability on time scales from weeks to several years, but no obvious trend for the 10-year period. The warmest years, in descending order, were 1987, 1988, 1983, and 1980. The years 1984, 1985, and 1986 were the coolest.

“…no obvious trend for the 10-year period”, probably didn’t go over too well. Continue reading
