NASA Warns Earth May Be Entering a Period of “Global Cooling” 6

NASA: We May Be On the Verge of a “Mini-Maunder” Event.

Global Research, January 13, 2013
In-depth Report:

All climate scientists agree that the sun affects Earth’s climate to some extent. They only disagree about whether or not the effect form the sun is minor compared to man-made causes.

We noted in 2011:

This week, scientists from the US Solar Observatory and the US Air Force Research Laboratory have discovered – to their great surprise – that the sun’s activity is declining, and that we might experience the lowest solar output we’ve seen since 1645-1715. The Register describes it in dramatic tones:

What may be the science story of the century is breaking this evening.

Scientists who are convinced that global warming is a serious threat to our planet say that such a reduced solar output would simply buy us more time … delaying the warming trend, but not stopping or reversing it.

On the other hand, scientists who are skeptical about global warming say that the threat is a new mini ice age. (Remember that scientists have been convinced in the past that we would have a new ice age, and even considered pouring soot over the arctic in the 1970s to help melt the ice – in order to prevent another ice age. Obama’s top science advisor was one of those warning of a new ice age in the 1970s. And see this.)

NASA reports this week that we may be on the verge of another Maunder Minimum (a period with an unusually low number of sunspots, leading to colder temperatures):

Much has been made of the probable connection between the Maunder Minimum, a 70-year deficit of sunspots in the late 17th-early 18th century, and the coldest part of the Little Ice Age, during which Europe and North America were subjected to bitterly cold winters. The mechanism for that regional cooling could have been a drop in the sun’s EUV output; this is, however, speculative.

The sun could be on the threshold of a mini-Maunder event right now. Ongoing Solar Cycle 24 is the weakest in more than 50 years. Moreover, there is (controversial) evidence of a long-term weakening trend in the magnetic field strength of sunspots. Matt Penn and William Livingston of the National Solar Observatory predict that by the time Solar Cycle 25 arrives, magnetic fields on the sun will be so weak that few if any sunspots will be formed. Independent lines of research involving helioseismology and surface polar fields tend to support their conclusion.

NASA explains that interactions between the sun, sources of cosmic radiation and the Earth are very complicated, and it takes an interdisciplinary team of heliophysicists, chemists and others to quantify what is really going on. And the Earth’s climate is also affected by cosmic radiation.

So – even if NASA’s prediction of a period of an unusually low amount of sun spots is proven correct – it is hard to know whether that will lead to a large or small reduction in temperature trends.

Solar Variability and Terrestrial Climate

Jan. 8, 2013:  In the galactic scheme of things, the Sun is a remarkably constant star.  While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our own sun varies a measly 0.1% over the course of the 11-year solar cycle.

There is, however, a dawning realization among researchers that even these apparently tiny variations can have a significant effect on terrestrial climate. A new report issued by the National Research Council (NRC), “The Effects of Solar Variability on Earth’s Climate,” lays out some of the surprisingly complex ways that solar activity can make itself felt on our planet.  ♦

Sun-Climate (cycle, strip)

These six extreme UV images of the sun, taken by NASA’s Solar Dynamics Observatory, track the rising level of solar activity as the sun ascends toward the peak of the latest 11-year sunspot cycle.
Understanding the sun-climate connection requires a breadth of expertise in fields such as plasma physics, solar activity, atmospheric chemistry and fluid dynamics, energetic particle physics, and even terrestrial history. No single researcher has the full range of knowledge required to solve the problem.  To make progress, the NRC had to assemble dozens of experts from many fields at a single workshop. 
The report summarizes their combined efforts to frame the problem in a truly multi-disciplinary context.   …More

  2. That rising level of soar activity is much weaker than previous cycles.
    The greatly reduced sunspots (reduced UV levels) and changing jet streams are responsible for the change in the jets streams and recent weather. I have no doubt that we can’t keep putting more cars on the roads and not see some effects. The ocean’s large fish have been depleted by over 90%. The areas of the ocean depleted of oxygen are increasing. Let’s solve these problems. Reduce the number of cars world wide (increase rail type or like transportation) and replenish and save the large fish of the oceans.

    • Cleaning up the planet is a lot more important than the CO2 issue. Lower the Co2 and continue to pollute seems to be the IPCC agenda.

      AGW is a lie motivated by global criminal element.

    • Well…Solar irradiance has not changed to threaten Solar panel efficiency, but the past 25 years of aerosol dumps/chemtrails have filtered sunlight significantly in earth’s atmosphere

      Listen to Dane Wiginton in “What are the world are they spraying” documentary to see how the military’s aggressive chemtrailing in California has measurably dropped his recharge rate by more than 20 to 30%
