I’ve been waiting for this statement, and the National Climate Assessment has helpfully provided it

Despite diffences with the treatment of others and the shambles of the PRP censorship debacle, I wish Anthony all the best in this. Have we been measuring mankind’s increase or temperature? I’m drawn to the former in light of the dreadful status of many airport and town weather stations. Next time it’s hot measure the temp on concrete vs grass.

Watts Up With That?

The National Climate Assessment report denies that siting and adjustments to the national temperature record has anything to do with increasing temperature trends. Note the newest hockey stick below.

Claim: Climate change threatens to worsen U.S. ozone pollution

Sigh. All in the mind. I wonder if they assumed an increase in magic unicorns also and fed that into the supercomputer? Disgraceful waste of effort, money and computer time.

Watts Up With That?

Smoggy skies in Los Angeles as viewed from the Getty Museum Visible pollutants can react with sunlight to create invisible ozone pollution, which frequently reaches unhealthy levels in major cities like Los Angeles. New research indicates that the pollution may worsen in coming decades due to chemical reactions in the air associated with climate change. (Wikimedia photo by Thomas.)

From UCAR:  BOULDER—Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by the National Center for Atmospheric Research (NCAR). The detailed study shows that Americans face the risk of a 70 percent increase in unhealthy summertime ozone levels by 2050.

This is because warmer temperatures and other changes in the atmosphere related to a changing climate, including higher atmospheric levels of methane, spur chemical reactions that lead to ozone.

Unless emissions of specific pollutants that are associated with the formation of ozone are sharply cut, almost all…

Significant Arctic Sea Ice Story a Possibility This Year

Watts Up With That?

Joe Bastardi writes on the Patriot Post:

There is a huge event being forecasted this year by the CFSV2, and I don’t know if anyone else is mentioning this. For the first time in over a decade, the Arctic sea ice anomaly in the summer is forecast to be near or above normal for a time! While it has approached the normals at the end of the winter season a couple of times because of new ice growth, this signals something completely different – that multiyear growth means business – and it shows the theory on the Atlantic Multidecadal Oscillation (AMO) is likely to be on target.

Once it flips, this red herring of climate panic will be gone. Global and Southern Hemisphere anomalies are already unmentionable since the former is well above normal and the latter is routinely busting daily records.

South Australian spring rain 3 weeks later than 100 years ago, solar blamed

Tallbloke's Talkshop




A detailed analysis of the rainfall of Adelaide has established that periodic changes occur in the incidence and duration of the winter rains. These changes have a period and amplitude of approximately 23 years and 30 days respectively, and superimposed on them is a long-term trend which is manifested by protraction of the latter half of the season, spring rains now occurring about 3 weeks later than they did just over 100 years ago. The total quantity of rain precipitated has shown no statistical significant changes.

As Talkshop readers will know all too well Tim does tongue in cheek, “Manuscript received January 25, 1954”

This paper has most things including academic sensitivity to criticism, a riposte to past words.

What the National Climate Assessment Doesn’t Tell You

Watts Up With That?


The Obama Administration this week is set to release the latest version of the National Climate Assessment—a report which is supposed to detail the potential impacts that climate change will have on the United States.  The report overly focuses on the supposed negative impacts from climate change while largely dismissing or ignoring the positives from climate change.

The bias in the National Climate Assessment (NCA) towards pessimism (which we have previously detailed here) has implications throughout the federal regulatory process because the NCA is cited (either directly or indirectly) as a primary source for the science of climate change for justifying federal regulation aimed towards mitigating greenhouse gas emissions. Since the NCA gets it wrong, so does everyone else.

Global Warming a Bizaare Science


Modern-day Helena

Most everything we know, our minute-by-minute real knowledge of the world — an enveloping understanding rooted in our liver and eliciting responses like goose bumps to a sudden cool draft on the backs or our necks — we learned from ancient Greeks. What we really know is what they mostly talked about for hundreds of years but never actually wrote down.

Let’s remember back on the birth of Western knowledge in the context of the most recent hot and cold climates on Earth—e.g., there was an 800-year warm period that peaked about 2100 years ago. The peak was a couple of centuries after a number of Jewish families led by Moses fled Egypt (the Exodus), maybe… 1,313 years before the birth of Christ (BC). After warming peaked there was about 500 years of cooling until the average global temperature would have been about what it is today. After that, cooling continued for another 250 years; and, then temperatures rose over the next 250 years, to about what they are today.

This period of 500 years ending around 0 BC of a relatively cold global climate on Earth…
