If three people get a rash, does that mean they all got their rash from the same source? No. Fact is that the warming of other planets is not necessarily relevant to our global warming problem. We have a different atmosphere. We are at a different relationship to the sun. Etc. Etc.
In regards to your articles, they are all pretty much irrelevant to the global warming discussion. Pluto is moving away from the sun, and its global warming causation is a mystery. Jupiter, according to YOUR article is not even experiencing global warming at all. Its climate is getting hotter at the equator, but COOLER at the poles. Completely different problem, not to mention the fact that it is a GAS planet.
Your last article is more relevant, but you miss an important point. One scientist's opinion does not make something a fact. The majority of scientists are in agreement that global warming, if not caused, is affected directly and dramatically by human action. In fact, that very article you cite uses other scientists that refute the idea that the sun is causing global warming.
Does that make you wrong? No. Of course not! The whole global warming debate is not a settled case, and much of the discussion, as with most scientific debates, are based on theories. That said, the logical and smart side to take if you are NOT an expert on the subject is the side of the majority. The fact is that most of us here are not experts on climate or global warming. You can cherry pick articles to show your point, but the other side can do the same thing. All it proves is that you are a good googler. Whoopity-doo.
In any case, IF the other planets are experiencing global warming, and the scientists cannot figure out why, what makes you think that WE can figure it out? Hmm...

The evidence that other plants are warming has been greatly exaggerated. The first example, Pluto, is a planet in a highly elliptical orbit. The varying amount of solar energy it absorbs may excite internal geological processes that affect the surface temperature. The "warming" on Mars relates to one small region, over a very limited period of time. Like anecdotal evidence of cooling or warming over small regions of the Earth over short time periods, this observation is essentially irrelevant to the problem. Planets with atmospheres show some natural variability in temperature resulting from normal climatic and seasonal changes. There is absolutely no evidence of any net changes in total solar output, either in electromagnetic flux or particles, over the past several decades during which these things have been closely monitored by satellite.

Well....maybe you could answer this question....how are these things related?
Changes in orbits of the other planets and some increase in solar activity has increased the temp on other planets. It is also well accepted the Earth gets its "heat" from the sun( just in case you don't BELIEVE in photosynthesis, the solar system or other concepts science has brought you, like your computer.) And it is also known that variation in sun activity and the earth's orbit can effect temps on Earth. It has been suggested this was the cause of the ice ages. Of course, you probably don't believe in them either...just a guess.
however, the data suggest that these temperature variations caused by sun activity and orbit changes are much less than the observed temp changes.
In addition....as I stated before, this is not related. CO2 and other gases (e.g. methane) trap heat in the atmosphere and are increasing the temperature. There is good scientific evidence to support this.
If you don't like the thought of global warming for some reason, then go the primary scientific literature and critique that and stop wasting every ones time.

Sun is not to blame for global warming: study
Wed Jul 11, 5:25 AM ET
Scientists on Wednesday said that the rise in global temperatures that has been detected over the past two decades cannot be blamed on the Sun, a theory espoused by climate-change sceptics.
British and Swiss researchers looked at data for radiation from the Sun, levels of which can cool or warm our planet's atmosphere.
They factored in a cycle which solar radiation goes through peaks and troughs of activity over a period of about 11 years.
Writing in Proceedings of the Royal Society A, a journal of Britain's de-facto academy of sciences, the team said that the Sun had been less active since 1985, even though global temperatures have continued to rise.
"Over the past 20 years, all the trends in the Sun that could have had an influence on the Earth's climate have been in the opposite direction to that required to explain the observed rise in global mean temperatures," they write.
The study is co-authored by Mike Lockwood of Britain's Rutherford Appleton Laboratory and Claus Froehlich of the World Radiation Centre in Switzerland.
The overwhelming consensus among scientists is that human activity is to blame for the rise in global temperatures. In its latest report, issued this year, the UN's Intergovernmental Panel on Climate Change (IPCC) said that this warming is already affecting the climate system.
Since 1900, the mean global atmospheric temperature has risen by 0.8 C (1.44 F), and the sea level by 10-20 centimetres (four to eight inches).
Levels of carbon dioxide (CO2), the main greenhouse gas, have risen by around a third since the Industrial Revolution and are now at their highest in 650,000 years. Eleven of the past 12 years rank among the dozen warmest years on record.
In the past few years, glaciers and snow and ice cover have fallen back sharply in alpine regions, the edges of the Greenland icesheet and on the Antarctic peninsula have shrunk, Arctic summer sea ice has thinned and retreated and Siberian and Canadian permafrost have shown signs of thaw and fallback.

Some of the other planetsare warming-others aren't. In the case of Mars, the cause is not a mythical rise in solar heating, it is a climate shift that has increased the amount of dust in the atmosphere--which acts like a greenhouse gas.
Non of which is relevant to the warming on Earth. That is primarily caused by the CO2 emissions of human activity.
Which everyone who actually knows anything about the science involved already knows. Inventing silly counter-theories doesn't change the facts.

The answers are in your own links, if you would take the trouble to read them.
Pluto began warming in 1988, shortly before reaching perihelion in 1989. (Perihelion is the closest point to the Sun in its highly elliptical 248-year orbit). The surface of Pluto has a lot of frozen methane, and perihelion passage caused some of it to sublime (turn to gas), increasing the methane in Pluto's atmosphere. Methane is a greenhouse gas, so the increase in methane caused more warmth, causing more methane to sublime, causing more warmth, and so on. This is an example of a climatic positive-feedback loop. The same kind of climatic feedbacks happen on earth all the time, which is one reason why anthropogenic CO2 has such a large effect here.
Jupiter is undergoing climate change, but not global warming. Its equator is getting warmer and its poles are getting cooler. This is believed to be part of a natural 70-year cycle, also caused by orbital forcing.
Mars looks like it's getting warmer at the south pole, but not at the north pole, so again it's not global warming.

The difference between the planets is pretty clear - the other planets have not got you or your family/friends living on it
If things get hotter/wilder here on Earth (regardless of who caused it) then your life - yes yours and mine - will get tougher in the next decades.... more storms, bigger storms, unpredictable rains, winds, and for Southern Oz .... less rainfall.
The best science in Oz, including NASA's atmospheric science, are unanimous - get ready for a rough ride and stop burning fossil fuels coz mit's making it hotter, with or without natural heat changes.
New York city and a whole pile of coast cities and island communities are now making plans for flooding (storms + sea level rise) .
If you dont think humans can slow this change - fine - you ought move to good rainfall area , well above sea level, and with good access to renewables or lots of Sun access with rich soils so that when food prices go way up (Peak Oil is 5 yrs away) u can still eat ....
In case you are wrong, be nice, use less fossil fuels and interstate foods....
K
Forget the other planets. YOU live on this one. Be prepared for change....

Did you even read those articles? A few selected quotes:
"Pluto's atmospheric pressure has tripled over the past 14 years, indicating a stark temperature rise, the researchers said. The change is likely a seasonal event, much as seasons on Earth change as the hemispheres alter their inclination to the Sun during the planet's annual orbit."
"While evidence suggests fluctuations in solar activity can affect climate on Earth, and that it has done so in the past, the majority of climate scientists and astrophysicists agree that the sun is not to blame for the current and historically sudden uptick in global temperatures on Earth, which seems to be mostly a mess created by our own species."
""It's believed that what drives climate change on Mars are orbital variations," said Jeffrey Plaut, a project scientist for NASA's Mars Odyssey mission. "The Earth also goes through orbital variations similar to that of Mars."
As for Abdussamatov's claim that solar fluctuations are causing Earth's current global warming, Charles Long, a climate physicist at Pacific Northwest National Laboratories in Washington, says the idea is nonsense.
"That's nuts," Long said in a telephone interview. "It doesn't make physical sense that that's the case."
"The radiation output of the Sun does fluctuate over the course of its 11-year solar cycle. But the change is only about one-tenth of 1 percent-not substantial enough to affect Earth's climate in dramatic ways, and certainly not enough to be the sole culprit of our planet's current warming trend, scientists say.
"The small measured changes in solar output and variations from one decade to the next are only on the order of a fraction of a percent, and if you do the calculations not even large enough to really provide a detectable signal in the surface temperature record," said Penn State meteorologist Michael Mann.
The link between solar activity and global warming is just another scapegoat for human-caused warming, Mann told LiveScience.
"Solar activity continues to be one of the last bastions of contrarians," Mann said. "People who don't accept the existence of anthropogenic climate change still try to point to solar activity."
Look, if global warming were due to the sun, every planet and moon in the solar system would be warming inversely proportionately to its distance from the sun. Where's the warming on Mercury, Venus, Saturn, Uranus, and Neptune? Even Mars? Only parts of Mars are warming - the second ice cap is growing!
This question has been answered many times.

Global Warming on our planet has two components.
One component is from natural forces over which we have no control.
The other component is from human activity, that is mostly carbon dioxide emissions.
One of the natural forces over which we have no control is solar output which has been increasing and would be expected to warm all of the planets in the solar system.
Carbon dioxide emissions from human activity cause warming above and beyond what we would expect just from increases in solar output.
The challenge is what do you do about it.
Al Gore made his recommendation last weekend that all of the developed countries cut back their carbon dioxide emissions by 90% of what they are today.
The only way that we can accomplish that is to shut down all motorized transportation systems worldwide. There can be no more automobiles, motorscooters,motorcycles, buses, trains, planes or shipping.
Next we must shut down all manufacturing, steel making and cement making.
Next we must shut down the generation of all electricity by the use of fossil fuels.
Next we must stop the heating of all homes, factories, and offices even when it is below zero degrees utside.
Next we must stop the cooking of all food.
Next we must stop the heating of all water for washing and bathing.
We must learn to bathe in cold water.
The reductions in carbon dioxide emissions that we get from more recycling, turning out the lights and buying hybrid cars are so small they will not even have a detectable effect on reducing the component of Global Warming that is caused by carbon dioxide emissions.
We cannot stop Global Warming. We cannot even slow it down unless we are willing to return to a primitive stone age hunter gatherer way of life.
If we cannot stop Global Warming or at least slow it down significantly, can we mitigate the effects of global Warming at a reasonable cost?
The good news is that we can mitigate the effects of Global Warming at reasonable cost if we start now.
We must accept the fact that Global Warming is a fact of modern life and we all cause Global Warming to some extent.
We must focus on mitigating the effects of Global Warming rather than engaging in immature finger pointing at people who are suspected of using more energy than we think they should.
The sea levels will rise.
Fortunately most low lying areas can be protected with dike systems similar to those in aHolland that are used to hold back the sea.
For the few areas that we cannot protect with dikes, we can relocate the population to higher ground.
Hurricanes will become stronger and more frequent. We will have to upgrade our disaster preparedness systems and we should help the poor countries upgrade their disaster preparedness systems.
There will be more droughts. We can help with supplemental water supplies and desalination plants.
We cannot stop Global Warming or even slow it down significantly.
Fortunately we can mitigate the effects of Global Warming with today's technology at reasonable cost.

probably exactly for the reason it states in your links..SEASONAL CHANGE!
There isn't any conclusive evidence that suggest they are experiencing anything similar to what Earth is. If they are, than we are in even bigger trouble, because those other planets....no Ozone layer to block radiation from the sun, so they should be warming faster!
If the sun is so responsible as you suggest, then why aren't planets closer to the source warming outside their seasonal patterns??
these warming trend you people keep popping up as anti-global warming arguments, are guesses. we don't know enough about the climate on other planets to even make an educated guess!

That is irrelevant to Earth. Consider the miles apart and the variables, why would those planets that may have warming trends have any relationship to Earth? They don't.
