Does NASA’s Latest Study Confirm Global Warming?

By Anthony Watts – Re-Blogged From WUWT

Some heated claims were made in a recently published scientific paper, “Recent Global Warming as Confirmed by AIRS,” authored by Susskind et al. One of the co-authors is NASA’s Dr. Gavin Schmidt, keeper of the world’s most widely used dataset on global warming: NASA GISTEMP

Press coverage for the paper was strong. ScienceDaily said that the study “verified global warming trends.” U.S. News and World Report’s headline read, “NASA Study Confirms Global Warming Trends.” A Washington Post headline read, “Satellite confirms key NASA temperature data: The planet is warming — and fast,” with the author of the article adding, “New evidence suggests one of the most important climate change data sets is getting the right answer.”

September 2018 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

By Bob Tisdale – Re-Blogged From WUWT

This post provides updates of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS through September 2018 and HADCRUT4 and NOAA NCEI (formerly NOAA NCDC) through August 2018—and of the two suppliers of satellite-based lower troposphere temperature composites (RSS and UAH) through September 2018. It also includes a few model-data comparisons.

This is simply an update, but it includes a good amount of background information for those new to the datasets. Because it is an update, there is no overview or summary for this post. There are, however, simple monthly summaries for the individual datasets. So for those familiar with the datasets, simply fast-forward to the graphs and read the summaries under the headings of “Update”.

New RSS TLT Data is Not Believable

By Bob Tisdale – Re-Blogged From WUWT

In advance of my September 2018 global surface and lower troposphere temperature anomaly update, this is a very quick introduction to the new (over a year old) lower troposphere temperature anomaly data from RSS (Remote Sensing Systems)…just three graphs.

As you likely know, I haven’t published a monthly global temperature update in almost 2 years. Since then, in July 2017, RSS released their version 4.0 lower troposphere temperature (TLT) anomaly data. See the RSS webpage FAQ about the V4.0 TLT Update for more insights.

The Abject Failure of Official Global-Warming Predictions

By Monckton of Brenchley – Re-Blogged From http://www.WattsUpWithThat.com

The IPCC published its First Assessment Report a quarter of a century ago, in 1990. The Second Assessment Report came out 20 years ago, the Third 15 years ago. Even 15 years is enough to test whether the models’ predictions have proven prophetic. In 2008, NOAA’s report on the State of the Global Climate, published as a supplement to the Bulletin of the American Meteorological Society, said: “The simulations rule out (at the 95% level) zero trends for intervals of 15 yr or more, suggesting that an observed absence of warming of this duration is needed to create a discrepancy with the expected present-day warming rate.”

To the continuing embarrassment of the profiteers of doom, the least-squares linear-regression trends on Dr Roy Spencer’s UAH satellite dataset shows no global warming at all for 18 years 6 months, despite a continuing (and gently accelerating) increase in atmospheric CO2 concentration, shown on the graph as a gray trace:

Weekly Climate and Energy News Roundup #210

The Week That Was: December 19, 2015 – Brought to You by www.SEPP.org

By Ken Haapala, President, Science and Environmental Policy Project

COP-21: The Conference of Parties (COP-21) of the United Nations’ Framework Convention on Climate Change (UNFCCC) is over. With great fanfare, an agreement was signed. The parties agreed to agree to try to limit carbon dioxide emissions. The agreement will have no identifiable effect on global climate change, because the UN Intergovernmental Panel on Climate Change (IPCC) has failed to establish the influence that human carbon dioxide emissions (CO2) have on climate. This “scientific body” has failed to distinguish between natural variation of climate, which has been ongoing for hundreds of millions of years, and the human influence, if any, of CO2 on this natural variation. Multiple studies that have the same flaw are just more of the same.

Further, no global climate model has been validated and there has been no effort, announced to the public, to validate one, in spite of billions of dollars spent by governments. This failure indicates there is a major problem in the publicly announced IPCC science, most likely because the influence of CO2 on climate is small, rendering these costly efforts to regulate CO2 insignificant. As Richard Lindzen said of the effect of CO2 on climate: “[It is] trivially true and numerically insignificant.”

A diverse array of views on the agreement is found below. In the major additions, it is an agreement, not a treaty, in the sense that it has no binding effect on the United States. A treaty would require approval of two-thirds of the Senate present. One purpose of this requirement in the US Constitution is to provide a check on presidential powers. Unlike in many other countries, a treaty in the US has the force of law. The Obama Administration realized it would not obtain approval of two-thirds of the Senate, thus delegates representing the Administration made last minute changes to the Agreement making it nonbinding and thereby avoiding Constitutionally required approval.

The Week That Was: August 29, 2015 – Brought to You by www.SEPP.org
THIS WEEK: By Ken Haapala, President, Science and Environmental Policy Project

Divergence: It is summertime in the US, and temperatures are warmer. Several readers have asked TWTW for comments on the recent claims that July 2015 was the hottest month ever and similar announcements by certain US government entities, including branches of the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA). These entities are making strong public statements that the globe continues to warm, and the future is dire. A humorist could comment that the closer we are to the 21st session of the Conference of the Parties (COP-21) of the United Nations Framework Convention on Climate Change (UNFCCC) to be held in Paris from November 30 to December 11, the hotter the globe becomes.

How Fast is the Earth Warming?

By Sheldon Walker – Re-Blogged From http://www.WattsUpWithThat.com

This article presents a method for calculating the Earth’s rate of warming, using the existing global temperature series.

It can be difficult to work out the Earth’s rate of warming. There are large variations in temperature from month to month, and different rates can be calculated depending upon the time interval and the end points chosen. A reasonable estimate can be made for long time intervals (100 years for example), but it would be useful if we could calculate the rate of warming for medium or short intervals. This would allow us to determine whether the rate of warming was increasing, decreasing, or staying the same.

Talking Truth to the Climate Consensus

A sound bite summary*

By Rud Istvan – Re-Blogged From http://www.WattsUpWithThat.com

The climate consensus has two levels of derogation for those who disagree. Climate ‘contrarians’ like Bjørn Lomborg disagree about mitigation policies. Climate ‘deniers’ like Judith Curry disagree about the underlying climatology. The consensus does not want disagreement, since the ‘science is settled’. They decline to engage (Schmidt/Spencer), disappear comments (Real Climate, the Guardian), refuse to host comments (LATimes), and loudly allege a fossil fuel funded ‘denier’ conspiracy (Grijalva). But they cannot avoid the occasional personal encounter. Following are some possible ‘silver bullets’.

Intellectual Freedom and Censorship: On her web site, Donna Laframboise, discusses an open letter to museums signed by 54 individuals who described themselves as “members of the scientific community. “ The letter objects to museums receiving funds from “those who profit from fossil fuels or fund lobby groups that misrepresent climate science.” The letter specifically discusses David Koch, who “is a major donor, exhibit sponsor and trustee on the Board of Directors at the Smithsonian’s National Museum of Natural History, and the American Museum of Natural History.” The letter asserts that “Mr. Koch also funds a large network of climate-change-denying organizations, spending over $67 million since 1997 to fund groups denying climate change science.”
