The Divergence between Surface and Lower Troposphere Global Temperature Datasets and its Implications

Bob Tisdale - Climate Observations

I include a graph in my monthly global surface temperature and lower troposphere temperature anomaly updates that compares the average of the global surface land+ocean temperature anomaly products (from GISS, NCEI and UKMO) to the average of the global lower troposphere temperature anomaly products (from RSS and UAH).  (See Figure 9 from the most recent August update for an example.) Because all of the suppliers use difference base years for their anomalies, I’ve recalculated the anomalies for all using the WMO-preferred reference period of 1981-2010.


Figure 1

My Figure 1 is similar to Figure 9 from those updates, but in it, I’ve also shown the linear trends for the global surface and lower troposphere temperature anomaly products.  The linear trend, the warming rate, presented by the average surface-based products is noticeably higher than the average lower troposphere products.   This, of course, according to Dr. Gavin Schmidt (head of NASA GISS)…

Study: Tropical Hotspot ‘Fingerprint’ Of Global Warming Doesn’t Exist In The Real World Data

Watts Up With That?

One of the main lines of evidence used by the Obama administration to justify its global warming regulations doesn’t exist in the real world, according to a new report by climate researchers.

Researchers analyzed temperature observations from satellites, weather balloons, weather stations and buoys and found the so-called “tropical hotspot” relied upon by the EPA to declare carbon dioxide a pollutant “simply does not exist in the real world.”

They found that once El Ninos are taken into account, “there is no ‘record setting’ warming to be concerned about.”

“These analysis results would appear to leave very, very little doubt but that EPA’s claim of a Tropical Hot Spot (THS), caused by rising atmospheric CO2 levels, simply does not exist in the real world,” reads the report…

L.A. Times climate science denial article instead shows the Times clearly denying well established climate science

Watts Up With That?

The L. A. Times published an article claiming that “Trump’s climate science denial clashes with the reality of rising seas in Florida


The article fails to address easily available and comprehensive NOAA tide gauge data updated through the year 2015 ( showing that the Florida coastline is experiencing no acceleration in coastal sea level rise and that the rate of coastal sea level rise there remains constant and consistent over more than 100 years of long term period tide gauge data measurements.

This long term steady rate of coastal sea level rise is documented at numerous locations around the state including Mayport, Fernandina Beach, Key West, St. Petersburg, Cedar Key, and Pensacola.







Climate alarmists have been falsely claiming for 3 decades now that coastal sea level rise is accelerating but NOAA tide gauge data demonstrates that this is not happening in Florida or anywhere else around…

New Study: Solar activity has a direct impact on Earth’s cloud cover

pia03149A team of scientists from the National Space Institute at the Technical University of Denmark (DTU Space) and the Racah Institute of Physics at the Hebrew University of Jerusalem has linked large solar eruptions to changes in Earth’s cloud cover in a study based on over 25 years of satellite observations.

The solar eruptions are known to shield Earth’s atmosphere from cosmic rays. However the new study, “The response of clouds and aerosols to cosmic ray decreases,” published in Journal of Geophysical Research: Space Physics, shows that the global cloud cover is simultaneously reduced, supporting the idea that cosmic rays are important for cloud formation. The eruptions cause a reduction in cloud fraction of about 2 percent corresponding to roughly a billion tonnes of liquid water disappearing from the atmosphere.

This new study, co-authored by Henrik Svensmark, is further validation of his game changing theory on the relationship of cosmic rays to cloud cover, and indeed, many important events in the history of the earth.

Measuring bias in the U.S. federally-funded climate research

Climate Etc.

by David Wojick

Semantic analysis of U.S. Federal budget documents indicates that the climate science research budget is heavily biased in favor of the paradigm of human-induced climate change.

Introducing the global-warming exaggeration factor X

Watts Up With That?


Guest essay by Christopher Monckton of Brenchley

Recently I provided – based on a characteristically interesting email from Roger Taguchi – a demonstration that IPCC has at least doubled true climate sensitivity. In this follow-up piece, will you please welcome the global-warming exaggeration factor X.

First, a breathless recap on my summary of Roger’s argument. Global temperature rose by 0.83 K from 1850-2016 (HadCRUT4), while CO2 concentration rose from 280 to 400 ppmv (NCEI). Officially-predicted pre-feedback sensitivity ΔT to this increase in CO2 concentration is thus 0.312 [5.35 ln (400/280)] = 0.60 K. Even if CO2 were the sole cause of all the warming, the post-feedback gain factor G would be 0.83/0.60 = 1.38. Then, since nearly all temperature feedbacks are short-acting, at doubled CO2 concentration and after all feedbacks had acted, equilibrium sensitivity ΔTeq would be only 0.312 x 5.35 ln…
