Deficit Cuts-Nick,Editor, Energy and Capital


You want deficits cut?

Then you're a supporter of renewable energy — and you're not alone.

In a recent Gotham Research poll, 73% of Americans (that extrapolates to 226 million people) said they want half or all fossil fuel subsidies repurposed to support solar and other renewables.

Some of you will dismiss that result. Some of you will deny it. Some of you will say it's a lie.

To each his own.

But here are some things you can't argue with*:
  1. The International Energy Agency's (IEA) chief economist has said phasing out billions of dollars of fossil fuel subsidies "would trigger vast savings in energy consumption... and change the energy game quickly and substantially." He added that fossil fuel subsidies are "the appendicitis of the global energy system which need to be removed for a healthy, sustainable development future."

  2. The IEA calculated that in 2008, 37 large developing countries spent about $557 billion in energy subsidies.

  3. An Environmental Law Institute study estimated $72 billion in tax breaks to U.S. fossil fuel companies from 2002-2008.

  4. An Organization for Economic Cooperation and Development (OECD) study found direct subsidies that artificially lower the cost of fossil fuels amounted to $312 billion globally in 2009.

And yet, when a co-author of the U.S. Energy Information Administration's World Energy Outlook was recently asked "if someone has actually done a credible, comprehensive, definitive count of how much taxpayers underwrite fossil fuels in this country", he said there is no such widely accepted count or number available...

I guess it is pretty hard to count up all the:

  • tax breaks

  • subsidies

  • the costs of government agencies that are set up to perform functions that these industries should pay full cost for doing — like figuring out how to stuff their pollution underground instead of wasting it on exorbitant, fantasy projects like "FutureGen"

  • military expenditures to protect oil shipping lanes

  • pollution forgiveness or remediation

  • rock-bottom-price access to public property, such as mountains, subsurface property, aquifers, and ocean waters — all of which fossil energy companies routinely wreck and pay comparatively little to fix

If we want a discussion about wasteful spending, I think this is a pretty good place to start.

Just throwing it out there.

Call it like you see it,

Nick Hodge

NASAs latest Climate Change Mission- Glory Departs Feb 23,

The NASA satellite Glory is set to launch into the Earths Atmosphere.  The Glory Launch will further Climatologist study of Airborne Particles (Aerosols) and how they affect the the Earths Climate.  They will be studying the ubiquitous particles (existing or being everywhere, especially at the same time; omnipresent) that directly influence the Climate by absorbing and reflecting the Sun's Radiation.

The Aerosol Particles they will be examining are-" few nanometers, less than the width of the smallest viruses, to several tens of micrometers, about the diameter of human hair" The Aerosols are Created by: Aerosols, Gases that lead to Aerosol formation, Fossil Fuel Exhaust Gases, and Natural causes. -- the amount of energy entering and exiting Earth's atmosphere. An accurate measurement of these impacts is important in order to anticipate future changes to our climate and how they may affect human life.

Godspeed and Good Luck to all those involved.

______________________________
Climatologists have known for decades that airborne particles called aerosols can have a powerful impact on the climate. However, pinpointing the magnitude of the effect has proven challenging because of difficulties associated with measuring the particles on a global scale.

Soon a new NASA satellite -- Glory -- should help scientists collect the data needed to provide firmer answers about the important particles. In California, engineers and technicians at Vandenberg Air Force Base are currently prepping Glory for a Feb. 23 launch.

Aerosols, or the gases that lead to their formation, can come from vehicle tailpipes and desert winds, from sea spray and fires, volcanic eruptions and factories. Even lush forests, soils, or communities of plankton in the ocean can be sources of certain types of aerosols.

The ubiquitous particles drift in Earth's atmosphere, from the stratosphere to the surface, and range in size from a few nanometers, less than the width of the smallest viruses, to several tens of micrometers, about the diameter of human hair.

The particles can directly influence climate by reflecting or absorbing the sun's radiation. In broad terms, this means bright-colored or translucent aerosols, such as sulfates and sea salt aerosols, tend to reflect radiation back towards space and cause cooling. In contrast, darker aerosols, such as black carbon and other types of carbonaceous particles, can absorb significant amounts of light and contribute to atmospheric warming.

Research to date suggests that the cooling from sulfates and other reflective aerosols overwhelms the warming effect of black carbon and other absorbing aerosols. Indeed, the best climate models available show that aerosol particles have had a cooling effect that has counteracted about half of the warming caused by the build-up of greenhouse gases since the 1880s.

"However, the models are far from perfect," said Glory Project Scientist Michael Mishchenko, a senior scientist at the Goddard Institute for Space Studies (GISS). "The range of uncertainty associated with the climate impact of aerosols is three or four times that of greenhouse gases," he said.

In comparison to greenhouse gases, aerosols are short-lived, and dynamic -- making the particles much harder to measure than long-lived and stable carbon dioxide. Aerosols usually remain suspended in the atmosphere for just a handful of days. Complicating matters, the particles can clump together to form hybrids that are difficult to distinguish.

In addition to scattering and absorbing light, aerosols can also modify clouds. They serve as the seeds of clouds, and can also affect cloud brightness and reflectivity, how long clouds last, and how much they precipitate. Reflective aerosols, like sulfates, for example, tend to brighten clouds and make them last longer, whereas black carbon from soot generally has the opposite effect.

Still, much remains unknown about aerosols and clouds. How do aerosols other than sulfates and black carbon affect clouds? How do aerosol impacts differ in warm and cold environments? Can infusions of aerosols near clouds spark self-reinforcing feedback cycles capable of affecting the climate?

The climate impact of clouds remains one of the largest uncertainties in climate science because of such unanswered questions. Some models suggest a mere 5 percent increase in cloud reflectivity could compensate for the entire increase in greenhouse gases from the modern industrial era, while others produce quite different outcomes.

Such unresolved issues prompted the Intergovernmental Panel on Climate Change (IPCC) to list the level of scientific understanding about aerosols as "low" in its last major report. Of the 25 climate models included by the IPCC in the Fourth Assessment Report, only a handful considered the scattering or absorbing effects of aerosol types other than sulfates.

"And less than a third of the models included aerosol impacts on clouds, even in a limited way, and those that did only considered sulfates," said Mian Chin, a physical scientist at NASA's Goddard Space Flight Center who specializes in modeling aerosols.

Glory, which contains an innovative aerosol-sensing instrument called the Aerosol Polarimetry Sensor (APS), aims to change this. By more accurately identifying a broad suite of aerosol types -- such as salt, mineral dust and smoke -- the instrument should help climatologists fill in key gaps in climate models.

While other NASA instruments -- including ground, aircraft, and satellite-based instruments -- have studied aerosols in the past, APS is NASA's first satellite-based instrument capable of measuring the polarization, the orientation of light-wave vibrations.

Raw sunlight, explained Mishchenko, is unpolarized. This means the waves oscillate in an unpredictable, random fashion as they move through space -- much like a rope would wiggle about if it had two people flapping its ends up and down in no particular pattern.

When light waves pass through certain types of filters called polarizers the waves are forced into a more ordered form. Imagine that wobbling rope trying to pass throw a narrow slit in a fence: only the waves vibrating at a certain angle could make it through. The result is polarized light, or light for which the waves only oscillate at specific angles. The surface of glass, sunglasses, even clouds of aerosol particles can polarize light.

APS's ability to measure the polarization of light scattered by aerosols and clouds is the key strength of the instrument. Other NASA satellite instruments have measured aerosols, but such instruments have typically done so by looking at the intensity of light -- the amplitude of the light waves -- not their polarization.

Yet, ground and aircraft-based studies, particularly those conducted with an aircraft instrument called the Research Scanning Polarimeter, which is quite similar to APS, show that polarized light contains the most information about aerosol features. "Earlier instruments can approximate the abundance of aerosol in general terms, but they leave much to be desired if you're trying to sort out the shape and composition of the particles," said APS Instrument Scientist Brian Cairns, also of GISS.

Large, spherical particles -- sea salt, for example -- leave a very different imprint on light in comparison to smaller and more irregularly-shaped particles such as black carbon. As a result, much like forensic scientists might study the details of blood droplets at a crime scene to reconstruct what happened, climatologists using Glory data will look to the polarization state of scattered light to work backwards and deduce the type of aerosol that must have scattered it.

Glory will not be the first Earth-observing satellite instrument to study polarization. French instruments that launched in 1996 and 2002 have as well, but the APS promises to be far more accurate and will look at the same particles from many more angles.

Nonetheless, interpreting Glory's APS data will be an extremely complex task. The mission will provide such a vast amount of new polarization data about aerosols that, in order to make sense of it, scientists will first have to validate APS science products with ground-based sensors scattered around the globe. Likewise, they will have to adapt and update mathematical techniques developed for an aircraft instrument to ensure they work well in a space environment.

All of this will take some time to refine and perfect. Mishchenko's team expects to release preliminary results as soon as possible after Glory launches, but he also expects to release improved and enhanced versions of Glory's APS data products over time.

A great deal of work lies ahead of Glory's science team and the aerosol science community more broadly, but the mission has the potential to produce profound advancements in understanding the perplexing particles. "Glory has the potential to offer a critical view of aerosols that we have never had from space before," said Glory's Deputy Project Scientist Ellsworth Welton.

Solar_Storm_Information-CME- QandA-Resources

In a previous Article I reported: More Active Sun Means Nasty Solar Storms Ahead.  In this post I added emphasis on the facts that:

  • "The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity," said R. Fisher NASA
  • But smart power grids, GPS navigation, air travel, financial services and emergency radio communications can all be knocked out by intense solar activity.
  • A major solar storm could cause twenty times more economic damage than Hurricane Katrina, warned the National Academy of Sciences in a 2008 report

It looks like the NASA Scientists were correct.  The Earth just received another blast of CME (Coronal Mass Ejection) Click Here to read about the latest Solar Storm that effected Chinas Radio Communications

 Here are web links for additional information on the Subject and provided links to the information - Damaging Effects caused by a Solar Storm or CME.

Solar Storms
Q: What is a Solar Storm

A solar storm is an electrified gas cloud that erupts from the surface of the sun into space. They come from the space around sunspots. Scientifically it's called a CME (Coronal Mass Ejection) and there is more than one stage to it. First comes a solar flare, then a radiation storm and finally the CME. If a powerful solar storm struck Earth, it could destroy crucial technology and cause a worldwide blackout.

Catastrophe Looming? The Risks of Rising Solar Storm Activity
Who Cares About Politics? THE SUN IS EXPLODING! (kinda)  | Space.com

The sun let loose its most powerful eruption in more than four years Monday night (Feb. 14), disrupting radio communications in China and generating concern around the world.  

But it could have been a lot worse, experts say.

Despite its strength, Monday’s solar storm was a baby compared to several previous blasts, and it provides just a hint of what the sun is capable of. A true monster storm has the potential to wreak havoc on a global scale, knocking out communications systems, endangering satellites and astronauts and causing perhaps trillions of dollars in damages.


  1. The sun’s activity cycle is ramping up, so more storms will likely be coming our way over the next few years
  2. The sun has grown more active over the last several months after rousing from a quiet period in its 11-year weather cycle last year.
