NASA hides page saying the Sun was the primary climate driver, and clouds and particles are more important than greenhouse gases

The NASA site used to have a page titled “What are the primary forcings of the Earth system?“. In 2010 this page said that the Sun is the major driver of Earth’s climate, that it controls all the major aspects, and we may be on the cusp of an ice age. Furthermore NASA Science said things like clouds, albedo and aerosol behaviour can have more powerful cooling effects that outdo the warming effect of CO2.

Today that page says Share the science and stay connected,  and “Access Denied”.





The Wayback Machine captured the same NASA “Primary Climate Forcings” link in 2010.




Here’s the text from the original page (my bolding).

NASA 2010: What are the primary forcings of the Earth system?

The Sun is the primary forcing of Earth’s climate system. Sunlight warms our world. Sunlight drives atmospheric and oceanic circulation patterns. Sunlight powers the process of photosynthesis that plants need to grow. Sunlight causes convection which carries warmth and water vapor up into the sky where clouds form and bring rain. In short, the Sun drives almost every aspect of our world’s climate system and makes possible life as we know it.

Earth’s orbit around and orientation toward the Sun change over spans of many thousands of years. In turn, these changing “orbital mechanics” force climate to change because they change where and how much sunlight reaches Earth. (Please see for more details.) Thus, changing Earth’s exposure to sunlight forces climate to change. According to scientists’ models of Earth’s orbit and orientation toward the Sun indicate that our world should be just beginning to enter a new period of cooling — perhaps the next ice age.

However, a new force for change has arisen: humans. After the industrial revolution, humans introduced increasing amounts of greenhouse gases into the atmosphere, and changed the surface of the landscape to an extent great enough to influence climate on local and global scales. By driving up carbon dioxide levels in the atmosphere (by about 30 percent), humans have increased its capacity to trap warmth near the surface.

Other important forcings of Earth’s climate system include such “variables” as clouds, airborne particulate matter, and surface brightness. Each of these varying features of Earth’s environment has the capacity to exceed the warming influence of greenhouse gases and cause our world to cool. For example, increased cloudiness would give more shade to the surface while reflecting more sunlight back to space. Increased airborne particles (or “aerosols”) would scatter and reflect more sunlight back to space, thereby cooling the surface. Major volcanic eruptions (such as that of Mt. Pinatubo in 1992) can inject so much aerosol into the atmosphere that, as it spreads around the globe, it reduces sunlight and cause Earth to cool. Likewise, increasing the surface area of highly reflective surface types, such as ice sheets, reflects greater amounts of sunlight back to space and causes Earth to cool.

Scientists are using NASA satellites to monitor all of the aforementioned forcings of Earth’s climate system to better understand how they are changing over time, and how any changes in them affect climate.

According to the Wayback Machine the text disappeared in early 2011 under Obama’s reign. Some people say Trump hides climate science, but Trump deletes propaganda, while Obama denies the Sun.

    Wonder if the BBC and UK press will report this historical issue of disappeared-science… ho ho!! This was during the so-called hiatus that followed the short period of rapid warming in the 1990s, so NASA clearly reprogrammed and homogenised their scientists in 2010!

    Has NASA hired Michael Mann to rid them of any pesky facts? First the Medieval Warming, then the Little Ice Age. Now the sun?????

      Michael Mann is to receive the Tyler Prize, together with NCAR’s Warren Washington.

      “The 2019 Tyler Prize has been awarded to climate scientists Warren Washington of the US National Center for Atmospheric Research and Michael Mann of Penn State University, US.

      “Professor Mann did not choose the easy way out,” says Naomi Oreskes of Harvard University, US, author of the book Merchants of Doubt. “For his courage in the face of this challenge, Mike Mann is not just a great scientist, but also a hero.”

      Some refer to the $200,000 Tyler Prize, which was founded in 1973 by the late John and Alice Tyler, as the “Nobel Prize for the environment”. The prize covers environmental science, environmental health and energy.

      Previous winners include climate scientists Richard Alley, Veerabhadran Ramanathan and Roger Revelle, biologist Edward O. Wilson, primatologist Jane Goodall and conservation biologists Anne Ehrlich and Paul Ehrlich.”

      Get things wrong and win prizes….

    Nice article, but they did not include the oceans, which are a very important influence on climate change over scales of decades to centuries, and perhaps even a few millennia. Water in all of its forms (gas, liquid, solid) is far and away the dominant driver of climate *change* over decades to centuries. Solar radiation reaching the earth is far and away the dominant driver of weather and climate on very short time scales (hours, days, months, seasons) and very long time scales (thousands of years and more), but probably does not influence decade to century climate *change* very much compared to water. Many people seem to overlook this nuance and falsely equate climate with climate change.

    The article says: “According to scientists’ models of Earth’s orbit and orientation toward the Sun indicate that our world should be just beginning to enter a new period of cooling — perhaps the next ice age.” However, by most geological definitions the earth is presently in an “ice age” that began at least about 3 million years ago with glaciation of the north polar region and more like at least 14 million years if you consider Antarctic glaciation sufficient. So they should have said “perhaps the next glacial period in our current ice age”.

      Where do the oceans get their heat? From the Sun!
      The sun heats the oceans which then act as a thermal store of the suns absorbed heat and circulate it around the planet. The oceans are important in circulating climate but ultimately they are driven by the Sun. Without the sun the oceans would be solid ice! In the end, 99.9% of climate and life on earth is driven by energy from the sun (minus a fractional input from the earths core leaking to the surface).

        bob n, you say:
        “Where do the oceans get their heat? From the Sun!”

        You’re exactly right. And that’s why I said:
        “Solar radiation reaching the earth is far and away the dominant driver of weather and climate …”

        However, be sure to make the distinction between climate and “climate change”. As far as we presently know, the annual average solar radiation reaching the earth varies by only about 1 watt/m^2 over scales of decades and centuries, which is a very small effect on “climate change” and is primarily an 11-year oscillation. It can take decades and centuries for heat redistribution from the ocean circulation to effect “climate change” and that effect can easily swamp the much smaller atmospheric temperature effects on “climate change” induced by solar radiation 11-year variation as well as gradually increasing CO2.

        Of course you are right oz4caster – but that is exactly the excuse that the Climate Science community has used to ignore the Sun altogether (TSI doesn’t change enough on the right timescales).

        BUT there are 100’s of scientific papers showing that solar indices effect changes in our climate on all sorts of timescales – magnetic effects, cosmic ray changes with solar wind etc. not just the headline 11 year cycle.

        Since in the last 20 years a third of all the CO2 man has ever emitted has been released and the temperature hasn’t changed at all really (ENSO excepted) the theory of AGW is surely now largely religion. The oceans dominate on nearly all timescales.

    “By driving up carbon dioxide levels in the atmosphere (by about 30 percent), humans have increased its capacity to trap warmth near the surface.”

    Well they have never bothered to prove that to any rigorous level. It is assumed to be true. and nobody wants to really research that now – it might prove embarrassing. Some scientists say (no no don’t switch off!!) that most of CO2’s effect is in the first 100 ppm,and even GCMs allow a logarithmically reducing effect. Additional CO2 has long passed the point of diminishing returns. Especially as astrophysicists have determined that CO2 does not exhibit the blackbody response which is hard-wired into all models.

    I like the bit that says we might be entering a new cooling phase – I can see the headlines now “See we told you there was an Ice Age coming – we need to reduce CO2 emissions”

    “Without thermal controls, the temperature of the orbiting Space Station’s Sun-facing side would soar to 250 degrees F (121 C), while thermometers on the dark side would plunge to minus 250 degrees F (-157 C). There might be a comfortable spot somewhere in the middle of the station,
    but searching for it wouldn’t be much fun!”

    Guess what, space is not cold, it’s HOT!!

    Like standing by a campfire, hot on the fireside, cold on the back side and without the atmosphere’s 0.3 albedo earth gets hotter not colder.

    Because the atmosphere and its associated albedo reflect away 30% of the incoming solar energy (like the reflective panel behind a car’s windshield) the earth is cooler with an atmosphere and not warmer per greenhouse theory.

    Because of the significant (>60%) non-radiative heat transfer processes of the atmospheric molecules the surface of the earth cannot radiate as a black body and there is no “extra” energy for the greenhouse gasses to “trap”/absorb/radiate/“warm” the earth.

    No greenhouse effect, no CO2 warming, no man caused climate change.

    No problem.

      Having been outside during a full solar eclipse, it went eerily cold very quickly. Great relief when the campfire started up again!

    Seems like NASA since 2010 has discovered there’s lots more money to be had in CO2 funding and that the sun isn’t a money spinner.

    Hidden under a cloud? Or rather, revealed by one. Clouds have always been so difficult for climatologists to model. Internet ones too it seems.

    Oceans, how much do sub oceanic volcanoes and hot gas fissures heat them? Never seen an informed estimate, the warmest always say they are insignificant.

    Sadly, too late for Europe which is going out of business as energy costs make them uncompetitive. China and India are laughing but may not realize that Europeans won’t have enough money to buy their exports.

    Climate corruption has been extant from the beginning. There could be no alarmism without scientists cheating. The alarmist crowd are unconcerned about integrity of data used to scare the public. HOW CAN YOU NEGLECT THE PRIMARY ROLE OF THE SUN IN CLIMATE UNLESS YOU DO NOT CARE ABOUT THE TRUTH? They have readily rewritten past like Michael Mann’s infamous fudged hockey stick graph of warming because climate science shoddy is only a means to an end.

    “No matter if the science of global warming is all phony…climate change provides the greatest opportunity to bring about justice and equality in the world.”
    – Christine Stewart,
    Former Canadian Minister of the Environment
    The goal is not about climate change but it is about economic change – to reverse the harsh impact of market friendly policies by redistributing wealth to underdeveloped countries. GOOD LUCK WITH THAT OLD FAILED SAW???

    EVE: Measuring the Sun’s Hidden Variability
    September 22, 2009

    “The problem is, human eyes are tuned to the wrong wavelength,” explains Tom Woods, a solar physicist at the University of Colorado in Boulder. “If you want to get a good look at solar activity, you need to look in the EUV.”
    . . .
    “The EUV portion of the sun’s spectrum is what changes most during a solar cycle,” says Woods, “and that is the part of the spectrum we will be observing.”

    NASA can ask that page to be deleted but if you archive your website with the link and then click on the link to archive it once more then it’s there permanently.

    Remember the wildfires in CA and how the alarmists were all over the air waves with “it is due to global warming and human caused climate change”. Funny now that Southern CA has a stretch of rain and cold weather they are silent. What scammers!
