Somebody is lying. Is there warming on other planets or not?

Question

I read a little while back that there is warming on all the other planets, like Mars, Jupiter, etc, similar to the warming on Earth. This was an article written by and supported by a promnent scientist.
Then later I read that this warming is a lie. The data shows that there is no warming on the other planets.
Then I read somewhere else that there is warming.

SOMEONE IS LYING. WHAT IS THE TRUTH??

Answer 1

Some planets are warming and some aren't. Some planets are undergoing climate change and some aren't. Some planets are warming in some places but not globally.

The important thing to remember is this: if earth's global warming were caused by the Sun, then ALL planets should be warming globally. All planets aren't. End of story.

Answer 2

It's a little of both. Some planets are warming, some are cooling, some are showing no trends at all. The causes for the climate changes on each is a separate and distinct issue from the warming here on Earth. In fact, the only connecting thread between the planets in our system is the sun, so if the changes were related they would have to be due to changes in solar output. However, the sun hasn't shown any trends since at least 1970, when warming has been fastest, and possibly 1940. Which all but rules it out as a source of the change.

Answer 3

There is warming on some of the other planets, but not all.

So it's not the Sun, which would warm them all.

On Mars, the NASA scientists who discovered the warming say it's most likely because of giant dust storms unique to Mars. Details here:

If anyone says all the planets are warming or all of them are not, they are indeed lying. Just some, for different reasons.

EDIT - Note that Tomcat's data below shows pretty clearly the Sun has been mostly cooler, dropping substantially between 1978 and 2003. That trend continues past the end of his graph in 2003 or so. A few skeptics like to point out the increase between 1985 and 1995, but that's a pretty selective reading of the data. And even it is nowhere near big enough to explain recent temperature increases.

Answer 4

There is warming on some other planets (not all) but it is for different reasons to the warming on Earth (so the fact that humans are causing global warming here has not been refuted).

Answer 5

Of course it is warming on other planets, it would be physically impossible for it not to, the sun has increased it's strength over the last 20 years. Or at least thats what the NASA data shows, (NASA: the only reason we know anything about the other planets).

PS.

And to a lesser extent ESA.

Answer 6

Some planets (such as Mars) have more extreme seasons than the Earth. When the trend (as we speak) is warmer, it's being called "global warming" by some.

Answer 7

Well, the sun is a pretty good generator of heat.....but, who ever is telling you that all the planets are actually undergoing "global warming" is full of it.
Then again there is the point 'similar to earth', maybe there's a point here to ponder.....................

Answer 8

it depends on who called it a lie! probably the manipulated press! just like the news is manipulated to say global warming is not man made....even though there are plenty of recources claiming other wise

Answer 9

You'll find that global warming is one of the most selective sciences. If you don't like a report, or if a finding goes against what you believe, then you can just throw it out while muttering the words "big oil".

After all, where would anyone get the idea that the sun is responsible for heat? It just provides light. Global warming produces the heat.

Answer 10

Other planets are warming too.
