Why Climate Models Run Hot

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

EPA administrator Pruitt wants to “Red Team” the catastrophic anthropogenic global warming (CAGW) consensus best reflected in the IPCC assessment reports (AR). At its core, CAGW rests on just three propositions:

1. CO2 is a ‘greenhouse’ gas retarding radiative cooling. This should not be in serious dispute since Tyndall experimentally proved it in 1859.

2. The Earth is warming. Although the details are in dispute because of temperature data quality problems and ‘adjustments’, the general fact is not. The Earth has been intermittently warming since the Little Ice Age (LIA) ended. For example, the last Thames Ice Fair was in 1814.

3. CO2 and its knock-on effects caused the recent warming, and climate models (such as the CMIP5 archive for IPCC AR5) predict this will continue to catastrophic levels. This is an extremely dubious proposition.

This guest post addresses proposition 3. It does so in a short sound bite ‘abstract’ useful for debating warmunists, and then in a typical WUWT full climate science guest post. It is a modest Red Team contribution.

Study Finds Temperature Adjustments Account For ‘Nearly All Of The Warming’ In Climate Data

By Michael Bastasch – Re-Blogged From The Daily Caller

A new study found adjustments made to global surface temperature readings by scientists in recent years “are totally inconsistent with published and credible U.S. and other temperature data.”

“Thus, it is impossible to conclude from the three published [global average surface temperature (GAST)] data sets that recent years have been the warmest ever – despite current claims of record setting warming,” according to a study published June 27 by two scientists and a veteran statistician.

The peer-reviewed study tried to validate surface temperature datasets managed by NASA, NOAA and the UK’s Met Office, all of which make adjustments to raw thermometer readings. Skeptics of man-made global warming have criticized the adjustments.

Climate scientists often apply adjustments to surface temperature thermometers to account for “biases” in the data. The new study doesn’t question the adjustments themselves but notes adjustments has increased the warming trend in published temperature records over the years.

Life on Earth Nearly Was Doomed By Too Little CO2

By Dennis T. Avery – Re-Blogged From http://www.WattsUpWithThat.com

During the last ice age, too little atmospheric carbon dioxide almost eradicated mankind

Aside from protests by Al Gore, Leonardo Di Caprio and friends, the public didn’t seem to raise its CO2 anguish much above the Russians-election frenzy when Trump exited the Paris Climate Accords.

Statistician Bjorn Lomborg had already pointed out that the Paris CO2 emission promises would cost $100 trillion dollars that no one has, and make only a 0.05 degree difference in Earth’s 2100 AD temperature. Others say perhaps a 0.2 degree C (0.3 degrees F) difference, and even that would hold only in the highly unlikely event that all parties actually kept their voluntary pledges.

What few realize, however, is that during the last Ice Age too little CO2 in the air almost eradicated mankind. That’s when much-colder water in oceans (that were 400 feet shallower than today) sucked most of the carbon dioxide from the air; half of North America, Europe and Asia were buried under mile-high glaciers that obliterated everything in their paths; and bitterly cold temperatures further retarded plant growth.

NYT Coins Ridiculous Meme: ‘Earth-scorching CO2’

By Kip Hansen – Re-Blogged From http://www.WattsUpWithThat.com

 

NYT_earth_scorching

The New York Times has set a new standard of scientific misrepresentation in this front page title to the latest climate change consensus salvo from Justin Gillis.   On the front page of the online edition of the NY Times for 26 June 2017, the title is given:  “Sharp Rise in Levels of Earth-Scorching Carbon Dioxide”

The actual title of the article, once one clicks through to it,  is “Carbon in Atmosphere Is Rising, Even as Emissions Stabilize”.

Who knows who at the NY Times thinks that characterizing CO2 as “Earth-scorching” is a valid scientific description of one of the absolutely necessary-for-life trace gases in the Earth’s atmosphere.  It certainly is not a proper journalistic description.

My objection is that it is a serious violation of Society of Professional Journalists’ Code of Ethics  specifically:

Provide context. Take special care not to misrepresent or oversimplify in promoting, previewing or summarizing a story.

Weekly Climate and Energy News Roundup #274

By Ken Haapala, President, Science and Environmental Policy Project

Brought to You by www.SEPP.org

Upheaval in Washington: One can describe the election of Donald Trump and the beginning of his administration as an upheaval against establishment Washington, including both political parties. Certainly, those expressing dissatisfaction at the early steps taken by the Trump administration are from multiple political alliances. Some political groups are outraged by the administration’s decision to leave the Paris Agreement (Accord), other groups are concerned that the Administration is moving too slowly. Each set has arguments that are, at least, partially right.

Some of those objecting to the US leaving the Paris agreement may have counted on lavish US spending on their pet schemes. As mentioned in June 10 TWTW, the Paris agreement involved side agreements that could be costly to the US taxpayer. For example, according to its defenders the Mission Innovation pact of 2015, involved a US commitment of over $6 billion in 2017 and increasing to over $12 billion in 2021. The purpose was to double expenditures on clean energy research and development, apparently without approval by Congress.

‘WASI’ Paris Climate Agreement

By Paul Driessen – Re-Blogged From http://www.WattsUpWithThat.com

Foreword: Following President Trump’s exit from the Paris Climate Treaty, a number of states, cities, universities, companies and institutions formed a “We are still in” consortium. Its members insist that they remain committed to Paris and are determined to reduce carbon dioxide emissions and prevent climate change.

As our article explains, this is all puffery and belief in tooth fairies. The issues and questions we raise ought to shame and embarrass WASI members – for spending countless billions of other people’s dollars to prevent an undetectable and irrelevant 0.01 degrees of global warming. We also ask whether jurisdictions within WASI states can take the “progressive” route and declare themselves sanctuary cities or counties, to protect their jobs and families against WASI dictates. Perhaps our article will persuade more Americans to make their voices heard, ask hard questions – and start resisting The Anti-Trump Resistance.

“No evidence” is a Useful Scientific Finding

By Michel de Rougemont – Re-Blogged From http://www.WattsUpWithThat.com

Heretic? You’re welcome!

Hysteric? Please cool down!

We hear that global warming is highly dependent on the concentration of carbon dioxide in the atmosphere, this gas that is required to sustain life on Earth and that is also emitted when burning flammable stuff, such as wood, coal, mineral and organic oils, or methane.

If you are told “this depends on that”, you are invited to examine available data observed over time to draw a representation of this on the y-axis vs. that on the x-axis.

So, in all logic, you should be interested in a representation of the temperature evolution in dependence of the atmospheric CO2 concentration.

Yes, you should, but, looking hard into the latest IPCC Report (the fifth of Working Group I, to be precise), no diagram of that sort can be found among its 1535 pages.
