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 (http://tidesandcurrents.noaa.gov/sltrends/sltrends_us.htm) 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.

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?

climate-x-factor

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…

Virtually indistinguishable – Comparing early 20th Century warming to late 20th Century warming

Watts Up With That?

Guest essay by Andy May

Many writers, including Professor Richard Lindzen and Ed Caryl have noticed the remarkable similarity in global warming observed from around 1910 to 1944 and 1975 to 2009. The similarity in slopes exists in all global surface temperature datasets. Figure 1 shows the HadCRUT version 4 dataset and the NASA GISS land (GHCN v3) and ocean (ERSST v4) temperature dataset. We’ve identified the two periods of interest on the figure. All datasets also show some cooling between 1945 and 1975.

Figure 2 shows the two periods overlain with data from the HadCRUT version 4 dataset. This display is scaled to actual average temperature. Unlike Figure one this figure and the next one use smoothed monthly data. In that way, we can see some of the variation within each year.

Big Chill: ‘Substantial Cooling’ Predicted Within The Next Few Years

Watts Up With That?

La Niña expected to contribute

From the Daily Star, 14 August 2016

Climate boffins believe the UK’s topsy-turvy climate is in for a chilly twist within the next few years as three major forms of climate change trigger “substantial cooling”.

lan-nina-forecast
Drastic changes in ocean conditions, greenhouse gases and a weakening of the sun threaten increasingly worsening winters of blistering blizzards and severe snowstorms for years to come.
This cocktail of climate threats, paired with “hasty climate policies”, could mean “rolling blackouts” in the UK over the next few years, plunging the country into long period of darkness.
These “worse case scenario” climate threats will hit the elderly hardest, leaving “some pensioners alone in the dark” on a freezing nights resigned to a “lonely death”.

It is thought these will be brought about for the most…
