What is the Default Temperature for the Earth?

August 27, 2017

Remember folks: it’s the Sun, not CO2.

Watts Up With That?

Guest Opinion: Dr. Tim Ball

The Earth’s atmosphere does not act like a greenhouse. The analogy was partially developed to help students understand the apparent disparity between energy coming in from the sun and leaving the Earth to space. However, its greater value was in creating the global warming deception because it automatically triggered thoughts of increasing artificial heat. The reality is the default temperature for the earth is cold, but the greenhouse analogy has put all the attention on the heat. Partial proof is in the fact that the Intergovernmental Panel on Climate Change (IPCC) addresses only the negative impacts of warming. Climate history shows that for flora and fauna (yes, us) there are many more positive effects for warming than negative effects for cooling.

The eclipse is a good opportunity to re-examine the thinking at the basis of this situation. How much did the temperature drop along the…

Approximately 66% of global surface temperature data consists of estimated values

And yet we should take drastic and extreme economy and liberty-killing measures… based on guesswork. Right.

Summary of GHCN Adjustment-Model Effects on Temperature Data

Guest essay by John Goetz

As the debate over whether or not this year will be the hottest year ever burns on, it is worth revisiting a large part of the data used to make this determination: GHCN v3.

The charts in this post use the dataset downloaded at approximately 2:00 PM on 9/23/2015 from the GHCN FTP Site.

The monthly GHCN V3 temperature record that is used by GISS undergoes an adjustment process after quality-control checks are done. The adjustments that are done are described at a high-level here.

The adjustments are somewhat controversial, because they take presumably raw and accurate data, run it through one or more mathematical models, and produce an estimate of what the temperature might have been given a set of conditions. For example, the time of observation adjustment (TOB) takes a raw data point…

Inquiry Launched Into Global Temperature Data Integrity

April 26, 2015

Long overdue. The state of surface temperature data, on which so much of the climate alarmist claims lie, is nothing short of scandalous. Fingers crossed the commission takes a hard, unbiased look.

Watts Up With That?

The International Temperature Data Review Project

London, 26 April 2015 – The London-based think-tank the Global Warming Policy Foundation is today launching a major inquiry into the integrity of the official global surface temperature records.
An international team of eminent climatologists, physicists and statisticians has been assembled under the chairmanship of Professor Terence Kealey, the former vice-chancellor of the University of Buckingham. Questions have been raised about the reliability of the surface temperature data and the extent to which apparent warming trends may be artefacts of adjustments made after the data are collected. The inquiry will review the technical challenges in accurately measuring surface temperature, and will assess the extent of adjustments to the data, their integrity and whether they tend to increase or decrease the warming trend.
Launching the inquiry, Professor Kealey said:

“Many people have found the extent of adjustments to the data surprising. While we believe that…

RSS Shows No Warming For 15 Years (Now Includes February Data)

April 9, 2015

Well, here’s an inconvenient truth to set climate alarmists sputtering. Read on to see why “15 years” is significant. (Hint: because NOAA says so.)

Watts Up With That?

In the above graphic, the zero line from February 2000 has been offset to make it visible. It actually falls right on top of the zero trend line from December 1996.

The title may seem odd since RSS shows no trend for 18 years and 3 months now. The title was triggered by an exchange several years ago in which we were challenged to show there was no warming for 15 years. I promptly showed that to be the case with RSS, but was accused of cherry picking since I went on the other side of the 1998 El Nino. Some one else started on this side of the 1998 El Nino and was accused of not going 15 years. We could not win then. But now we…

Global warming? Where?

November 7, 2009

October 2009 was the third-coldest in the US for the last 115 years.

October_2009.JPGNow one month does not a trend make, but the evidence against the cult of anthropogenic global warming keeps piling up.
