but it bears mentioning (because of the astronomical nature of the
issue) that Mars, like Earth, experiences changes to its orbital
eccentricity and obliquity over long time scales (on Earth, they are
known as Milankovitch cycles). And because Mars doesn't have a large
Moon to mitigate the obliquity changes, and is more strongly perturbed
by Jupiter, its changes tend to be more severe than the Earth's.
Thus, you can't explain away anthropogenic climate change on Earth by
saying "Mars is warming up too, so the Sun must be to blame" because
there's a 50-50 chance that Mars's current direction of temperature
change is upward due to these long-period variations that have nothing
to do with the Sun.
This is a classic example of the fallacy of affirming the consequent:
"If A, then B. B, therefore A." In this case "An increase in solar
irradiance will warm Mars and the Earth. Mars and the Earth are
warming, therefore there has been an increase in solar irradiance." It
ignores the possibility of separate causes producing the same effect.
It's comparable to "Colds give me the sniffles. I have the sniffles,
therefore I have a cold" (ignoring the possibility that I have
allergies, or have been outside in cold temperatures).
Finally, a recent study has shown that changes in the Sun over the last
millennium are NOT to blame for the majority of terrestrial climate

Subject: [fulldome] Re: Any fulldome on climate or em spectrum?
The planetarium in Ridderkerk, the Netherlands is making a fulldome
video show at the moment about global warming. This is an initiative of
Ad Los, the owner of the planetarium. Mirage3D is creating the graphics
for this show. Show completion date will be around the end of this year.
The show deals with the birth and death of stars, seasons and
precession, different ways of generating energy on Earth, climate
change, human influence, but also with the temperature rise on Mars over
the last 30 years which is near equal to that of the Earth. (Ad Los
calls this the "inconvenient truth" :) )

fulldome shows. Being primarily science education in nature at
present, many different scientific theories will be presented,
"theories" being the key word. Theories change over time as evidence
is evaluated. I remember reading about an ice age that was on its
way not too many years ago.
The fulldome experience will greatly be enriched by the visual
exploration of the many differing scientific theories out there. I
would be very disappointed to see our forum turn into a battleground
where one theory is marketed over another.

It seems everyone is out to promote their particular world view - including
the creationists. A little controversy in the dome might be good for us,
however. So many planetarium shows "play it safe" resulting in a pretty
boring presentation, and even cutting-edge fulldome programs only push the
I think the dome is a great place to ask the "big questions," like where did
we come from, where are we going, what is really happening with the weather,
etc. Staying tightly aligned with mainstream scientific "doctrine" can be a
formula for boredom - even for visitors who are scientists! The cutting edge
of science has always been on the fringes of what is knowable - that is
where imagination, creativity and vision are activated - the juices that
engage and motivate most of the greatest scientists in the first place.
I think where popular media steps over the line is in confusing speculation
(a valid first-step in the scientific process) with valid or falsifiable
scientific theory. There are many things in life that lie outside of the
verifiable bounds of science... unanswered questions are, by definition,
unknowable or difficult to validate or falsify. A scientist is not wrong to
ask big questions (or even fun questions ala Mythbusters) and to speculate
possible answers - this is the early stage of formulating a hypotheses. Is
there life on other planets? Might there be life after death? Is nature
inherently "intelligent?" Might we one day travel faster than the speed of
light? These questions fire the imagination and are not anathema to
science. It is claiming that you have the answers - without offering
sufficient proof - that is taboo to the scientific process.
There is a place for the dissemination of scientific knowledge in the dome,
to be sure. However I think the highest use of the immersive medium as an
informal educational tool is to open minds and hearts to new possibilities
and visions (new world views, if you will), to ask "what if," and to
activate a sense of mystery in the visitor, while at the same time
empowering them to realize that they themselves could some day be the one to
solve these unanswered questions (using the STEM toolbox). There are
countless stories of great scientists and engineers who were driven by a
childhood dream which, at the time, seemed like an impossible quest.
I also think that it is important for educators to not just disseminate the
tools of STEM (science, engineering, technology and math), but to encourage
the use of these powerful tools with a sense of social and environmental
responsibility. Again, the dome is a great place to inspire young minds
with a sense that we are all interconnected in the sphere of life called
earth, and the quality of our life depends greatly on our choices and
behaviors. The tools of STEM, when used wisely, can greatly improve our
lives. When used unconsciously or out of fear, these tools yield a very
dystopian future. By inspiring our future scientists, engineers,
technicians and mathematicians with positive visions and noble quests for
the future, we provide a compass heading for their careers to blossom into
good fruits for all of humanity.
