Good luck debunking NATIONAL GEOGRAPHIC, MIT AND SPACE.COM.
Zokay... but that's not particularly hard to do when National Geographic, MIT and space.com debunk their own articles...if you just read the whole
thing that is.
The following quotes are all from your own links that you posted:
The conventional theory is that climate changes on Mars can be explained primarily by small alterations in the planet's orbit and tilt, not by
changes in the sun.
"Wobbles in the orbit of Mars are the main cause of its climate change in the current era," Oxford's Wilson explained.
Pluto's orbit is much more elliptical than that of the other planets, and its rotational axis is tipped by a large angle relative to its orbit.
Both factors could contribute to drastic seasonal changes.
David Tholen, an astronomer at the University of Hawaii who measured the size of Pluto in the late 1980s using a series of occultations and
eclipses involving Pluto's satellite, noted that even though Pluto was closest to the sun in 1989, a warming trend 13 years later shouldn't be
unexpected. "It takes time for materials to warm up and cool off, which is why the hottest part of the day on Earth is usually around 2 or 3 p.m.
rather than local noon, when sunlight is the most intense," Tholen said. Because Pluto's year is equal to about 250 Earth years, 13 years after
Pluto's closest approach to the Sun is like 1:15 p.m. on Earth. "This warming trend on Pluto could easily last for another 13 years," Tholen
The Pluto article points out it's climate change is likely due to residual pressure changes, and even offers this perfect segue:
Pluto and Neptune's largest moon, Triton, are presently about the same distance from the sun, and each has a predominantly nitrogen atmosphere
(with a surface pressure 100,000 times less than that on Earth), so one might expect similar processes to be occurring on these two bodies.
The moon is approaching an extreme southern summer, a season that occurs every few hundred years. During this special time, the moon's southern
hemisphere receives more direct sunlight. The equivalent on Earth would be having the sun directly overhead at noon north of Lake Superior during a
Elliot and his colleagues believe that Triton's temperature has increased because of indications that the pressure of the atmosphere has increased.
Because of the unusually strong correlation between Triton's surface ice temperature and its atmospheric pressure, Elliot said scientists can infer a
temperature increase of 3 degrees Fahrenheit over nine years based on its recent increase in surface vapor pressure. Any ice on Triton that warms up a
little results in a big increase in atmospheric pressure as the vaporized gas joins the atmosphere.
The global change cycle began when the last of the white oval-shaped storms formed south of the Great Red Spot in 1939. As the storms started to
merge between 1998 and 2000, the mixing of heat began to slow down at that latitude and has continued slowing ever since.
The movement of heat from the equator to Jupiter's south pole is expected to stop at 34 degrees southern latitude, where Red Spot Jr. is forming.
This will create a big wall and stop the mixing of heat and airflow, the thinking goes. As a result, areas around the equator become warmer, while the
poles can start to cool down.
What this is essentially saying is that Jupiter is not
warming, it is simply undergoing internal
changes that are redistributing heat
around the planet. You can read more about it here
So let's make this absolutely clear. Because the whole "all the planets in the Solar System are warming" is one of the most common myths floating
around the internet trying to undermine 150+ years of climate science
that has not only observed
the Earth warming, it explained it
beforehand and even PREDICTED it
Counting moons, there are something like 180 planetary bodies in our Solar System. Here we have 4 that are supposedly warming. That's 2.22%
It's also conveniently ignoring the other bodies that have been observed to
Furthermore two of the above have very mundane explanations that are related, one of them is not even warming, and there is
a lot of controversy over the fourth
. My other favorite thing about
people always pointing to Mars warming to debunk the idea of CO2 having a significant effect on Earth is you're talking about a planet
whose atmospheric composition is 95% CO2
One of the strongest pieces of evidence we have for anthropogenic warming on Earth is the historical data that shows even minor changes in CO2
concentration can greatly amplify and affect disproportionate changes in temperature:
The Biggest Control Knob: Carbon Dioxide in Earth's Climate History
So sorry, but this whole idea that all the planets in the Solar System are warming is nothing but a total utter myth. I find it pretty ridiculous that
people will get all worked up and excited around here about the end of the world as long as it involves some mysterious unseen force that is beyond
But when the
overwhelming majority of the world's scientists
are all preaching that it is completely something within our control, and that it needs to be
stopped asap, everybody smirks and starts labeling them hoaxers and fearmongerers and declaring how much smarter they are because they read some stuff
on teh interwebs.
