Is the Sun's increased temperature the true reason for global warming on earth and other planets?

Question

* Reports that Mars temperature increased similarly to ours have been given by the government.

* They also stated that dust storms or consistent patterns of particles in air help to hold in those increased heats.

* It begs one to wonder if it is just a product of an increase in sun heat radiation and not solely a human responsibility. We so often assume that WE are responsible for things as misunderstood as things larger than us and out of our control???

SOMEONE SHOULD REALLY GET ALL OF THEIR FACTS STRAIGHT...AND THAT IS WHY NOTHING SERIOUS HAS BEEN DONE TO STOP GLOBAL WARMING....WE JUST TALK ABOUT DOING THINGS

Answer 1

Global warming can be caused by a number of different things, but the type of atmosphere a planet has can help determine those causes.

The most well known cause of global warming on Earth is the accumulation of what are called "greenhouse gases" in the atmosphere. These gases include Carbon Dioxide, Methane and Nitrous Oxide and water vapor. This is called the "greenhouse effect". The reason this is such a hotly debated topic is that human activity has been blamed for alot of this.

Solar radiation IS a cause of global warming. Eccentricities in the Earth's orbit also play a role. I would have to say once again, however, that because each planet has a different atmosphere, is at a different distance from the Sun, etc.. that the causes vary from planet to planet.

"Known causes of global climate change, like cyclical eccentricities in Earth's rotation and orbit, as well as variations in the sun's energy output, are the primary causes of climate cycles measured over the last half million years. However, secondary greenhouse effects stemming from changes in the ability of a warming atmosphere to support greater concentrations of gases like water vapor and carbon dioxide also appear to play a significant role. As demonstrated in the data above, of all Earth's greenhouse gases, water vapor is by far the dominant player." (see below for source)

Answer 2

Mars has got a totally different atmosphere to ours (more correctly it doesn't have an atmosphere as such). There is speculation that the temperature has risen by about the same amount as we've witnessed on Earth but it's not possible for the reasons to be the same. It's though it may be caused by massive dust storms on Mars - ones that extend for thousands of miles, certainly not like anything we have.

Another major difference is the temperature. On Mars the polar ice caps aren't frozen water but frozen gas. If the temperature on Mars rises ever so slightly massive amounts of Carbon Dioxide are released from the polar ice caps and this causes a greenhouse effect just as we have here on Earth. Agsin, in a different way.

It's speculation because there's not enough relaible evidence about what's happening on Mars but if the above theory is correct then Mars could be witnessing global warming with greenhouse gases being a contributory factor.

Also, Mars isn't warming everywhere, some places are cooling and as one ice cap melts the other expands. This happens on a yearly basis and is caused by seasonal variations, the same reason we have hot weather in summer and cold in winter.

As for the suns increased temperature causing global warming: It's a contributory factor at times of intense sunspot activity, this occurs in 11 year cycles so if global warming were caused by solar activity it should come and go at 11 year intervals. As you know this isn't the case.

The difference between the suns minimum and maximum heat output is very small, it deviates by less than one thousandth of the normal amount (1366 W/m²/yr ±1.3). This wouldn't be nearly enough to explain the temperature rises we've experienced here on earth. Solar Variation does contribute to global warming and cooling and over periods of many thousands and millions of years it can have a profound effect.

Nature changes things very very slowly, in the past ice ages have come and gone in periods of between 50 and 100 million years; temperatures, averaged out over time, fluctutate from one year to the next in millionths of a degree. There are shorter periods of much greater temperature changes but they're still only measurable in thousandths of a degree per year.

It would be wrong to say that the current global warming trend is manmade, just as it would be wrong to say it's natural. Both are contributory factors.

In respect of talking not doing: there are several schemes that are being currently being investigated, these are primarily focused on two things - reducing the amount of sunlight that reaches Earth (solar shades, solar mirrors, sulphur screens, cloudseeding etc) and removing carbon dioxide from our atmosphere (phytoplankton, artificial 'trees' and other forms of sequestration).

Answer 3

it should be confusing for Nibiru to be in charge for global warming at the same time as the issue would not exist. Does it check out all extraordinary to you, that some planet should be raising our temperature and we gained't even see it with the bare eye? If it became Earth-sized, it ought to should be farther than the orbit of Saturn as a fashion to be invisible to the bare eye. nevertheless, everybody with a first rate telescope ought to cope with to work out it. looks infrequently probable that it ought to reason such an effect at the same time as Jupiter, that could be a lot closer, has no effect on us in any respect. there is not any first rate clinical theory for any kind of doom in 2012. it is organic hogwash perpetuated by technique of the heritage channel. This, alongside with lots of the different bunk they have aired, proves that they are maximum probable *no longer* a strong source of advice. they're attracted to in spite of attracts an target audience, and obviously they haven't any criteria in any respect, about what they'll use to achieve that end.

Answer 4

What are your sources for this? Earth's temperature increased about one degree over the century. We did not have, and still don't have, the means to measure Mars' temperature that accurately. And, Mars' atmosphere is so thin it does not play a role in greenhouse effects. You can't make a comparison.
Particulate matter does not trap heat. It does cause clouds to form, which blocks sunlight. It's called the Albedo effect, and this generally cools the Earth.

Answer 5

actually it is a normal cycle, but it's based on the sun as well. Both are going through a warming trend because solar activity (sunspots, solar flares) is increaseing right now.

the earth has actually been a lot hotter and a lot cooler in the past, during the midevil ages it was several degrees hotter than it was now.

Answer 6

It could be that because threre is in fact a Mars version of Global Warming. But that is not the only casue we are partialy responsible for the global warming here but this shows that it is not all our fault.

Answer 7

I hear all the time : it hasn't been so warm since 50/100 years ago. I hear them in TV, on the radio, I hear my neighbours (older persons). What am I trying to say is that it has happen before, because they say it. So there's nothing to worry about, because history repeats. 100 years ago the Earth wasn't poluted and still it has happen.
