Where The Temperature Rules The Sun

Watts Up With That?

I’ve held for a long time that there is a regulatory mechanism in the tropics that keeps the earth’s temperature within very narrow bounds on average (e.g. ± 0.3°C over the 20th Century). This mechanism is the timing and amount of the daily emergence of the cumulus cloud field, and the timing and emergence of thunderstorms.

Now, the current paradigm is that the sun rules the temperature, and our daily experience seems to bear that out. When the amount of sun reaching the surface goes up, the temperature goes up. This has led to the claim that the temperature must perforce follow the forcing in a linear fashion. For those interested in the math, the claim is that changes in temperature are equal to changes in forcing times a constant called the “climate sensitivity”. And much energy has been wasted trying to determine the value of that constant.

Despite hundreds…

Study: finds a solar amplification mechanism by which solar activity & cosmic rays control climate

Watts Up With That?

The HockeySchtick writes: A paper published today in the Journal of Atmospheric and Solar-Terrestrial Physics finds another potential solar amplification mechanism mediated by galactic cosmic rays [GCRs] (and distinct from Svensmark’s cosmic ray theory of climate). The author demonstrates:

  • Solar modulation of GCR [Galactic Cosmic Rays] is translated down to the Earth climate.
  • The mediator of solar influence are energetic particles.
  • GCR impacts the O3 [ozone] budget in the lower stratosphere.
  • O3 influences the temperature and humidity near tropopause, and greenhouse effect.
  • Effectiveness of this mechanism depends on geomagnetic field intensity.

“In this paper we show that bi-decadal variability of solar magnetic field, modulating the intensity of galactic cosmic ray (GCR) at the outer boundary of heliosphere, could be easily tracked down to the Earth’s surface. The mediator of this influence is the lower stratospheric ozone, while the mechanism of signal translation consists of: (i) GCR impact on the lower stratospheric…

Wildfires: Separating Demagoguery from the Science

Watts Up With That?

Guest essay by Jim Steele Director emeritus Sierra Nevada Field Campus, San Francisco State University and author of Landscapes & Cycles: An Environmentalist’s Journey to Climate Skepticism

Published in Range Magazine winter 2017/2018

In 2016 Climate Central, notorious global warming demagogues, published the article Climate Change’s Fingerprints All Over California Wildfires. Ignoring a well-documented history of natural climate change, ignoring the ill-advised 20th century policy of fire suppression, and ignoring the increased percentage (~80 to 90%) of fires ignited by humans, Climate Central tried to persuade the public that California fires, (as well as all recent fires) are “part of a dire global warming-fueled trend toward larger, more frequent and intense wildfires.”

Whether you believe recent warming was natural or caused by rising CO2, warmer temperatures have promoted better growing conditions and that has been good for man and beast. During the cold Little Ice Age tree lines retreated. From…

Unbelievable: New $500 million Oroville dam spillway already has cracks

Watts Up With That?

CA Department of of Water Resources says: “don’t worry”, it’s “robust”.

Readers may recall that in February 2017, the spillway at Oroville dam eroded and collapsed due to the massive amount of water from El Nino weather pattern induced storms eroding concrete that had cracks in it that had not been properly maintained. The state DWR agency spent an estimated $500 million to rush a new spillway replacement into service by November 1st. Now it appears this rush job has cracks in the steel reinforced concrete, repeating the same start of the scenario that caused the collapse in the first place.

Feb 9th 2017 – concrete collapse at Oroville spillway

From ChicoER: Small cracks have appeared in the new concrete in the main spillway at Oroville Dam, but the state says they were expected and nothing to worry about.

An explanation of the “hairline cracks” was called for in a…

Trump’s EPA Backs a Climate Change Tweak Environmentalists Like

The Trump administration took a small step toward addressing climate change last week — it just didn’t put it quite in those words.

Without fanfare — or even a public announcement — the Environmental Protection Agencyissued an arcane rule that allows refrigerator and air-conditioner manufacturers to increase the amount of three cooling chemicals they can use safely. In a twist, the change was welcomed by manufacturers that want to adapt and use chemicals that would cause less global warming.

Home refrigerator makers in…

Does Air Pollution Really Shorten Life Spans?

Watts Up With That?

Guest essay by Dr. Indur M. Goklany

Periodically we are flooded with reports of air pollution episodes in various developing countries, and claims of their staggering death toll, and consequent reductions in life spans. The Economic Times (India), for example, recently claimed:

If you are in NCR [National Capital Region, i.e. Delhi] right now, you may have a shorter lifespan

Nov 09, 2017, 05.11 PM IST

Can’t breathe

With pollution levels in NCR 40 times the World Health Organization’s safe limit, your life expectancy could be cut short…

Killing you softly

The US embassy website said levels of the fine pollutants known as PM2.5 that are most harmful to health reached 703 — well over double the threshold of 300 that authorities class as hazardous. PM2.5 are particles with a diameter of 2.5 micrometers or less and a study recently found that a 10 µg/m3 (per cubic meter of air)…
