Is Al Gore talking about this?

I don't believe he's mentioned this small little bit of science info to his lecture series on the subject of global warming yet.

The UN report which is about to be released states categorically that solar fluctuations are not the primary cause of the current global warming trend - it is human caused.

In about 200 million years from now we won't have to worry about solar fluctuations contributing to any current warming trend.

Ach- we'll have a sunshade up by then.

Here's one I made to go in front of Venus. There are mirrors behind the planet to light the dark side during the long night..

Chances are, the closest star system that is very similiar to our own sun in terms of it's own evolution (same basic size, age, type and luminosity), Alpha Centauri is probably on the same schedule (or close to it) on becoming a Red Giant sun just like ours some day. So, I would chose for starters, heading to Zeta2 Reticuli to set up shop before our sun starts to turn up the heat a little. I think it probably already has. 200 million years from now, an air conditioner won't do you much good. Come to think of it, neither will a cold beer.

We might have to start this plan a little sooner than expected:

all stars undergo this process, its a byproduct of the gravity-fusion process.

I'd say our sun's evolution into becoming a Red Giant in a few billion years, to some extent, has probably already started. If mankind wants to hang out a little longer in our galaxy, no time better than the present than to start making some plans to get off planet Earth before things start to heat up around here. 200 million years and counting > 199,000,000, 198,000,000.........

Hello all

How about this for an "idea"

First you have a "headlight effect" for EM radiation emitted from a moving EM source (the Sun).
Second you have a dipole measurement of the Sun's velocity with respect to the CMBR (U2 Anisotropy Experiment, COBE and WMAP data).
Third you have the intersection of the Earth's ecliptic orbit (currently within 12deg) with the measured velocity vector of the Sun.
Fourth you have a 100,000 year cycle for Earth's ecliptic angle with respect to the ecliptic mean of the solar system.

What this gives is a 100,000 cycle of the Earth moving into and out of a stronger solar flux of EM radiation produced by the "headlight effect" of the Sun's motion through space.

New studies indicate that the sun is growing in solar irradiance and getting hotter adding heat to an Earth already thought to be warming by the Greenhouse effect.I've been telling you guys about this for more than a year. One of those magazines that only dentists subscribe to (like maybe Smithsonian) reported that the polar ice caps on Mars were melting. Since there are no humans on Mars burning fossil fuels, the only explanation for Mars's "global warming" had to be an increase in solar radiation.

This does not contradict the global warming theory for Earth, but it does partially contradict its anthropogenic slant. Considering how politicized that is, this is an important discovery. (Like, when did Al Gore become a scientist? The man is nothing more than a politician, and not a terribly bright--or even slick--one at that.)

What is the atmosphere like on Mars? What is its environmental history?

Does it have weather cycles?

Can we compare events on Mars with events on Earth?

Well, they orbit the same star and derive all their energy from that star. It's also pretty clear that man is not responsible for any change in temperature on Mars. So if the temperature on both planets is rising, and the large nuclear reactor they derive all their energy from is heating up, the conclusion seems obvious.

Of course reaching the obvious conclusion would not suit the political needs of global warming alarmists. So it will be delayed as long as possible.

I'm not to sure about martian rain showers or snow storms, but definetly there's probably a couple of frozen ponds somewhere on it's surface. Break out your ice skates.

What is the atmosphere like on Mars? What is its environmental history?

The atmosphere is very thin. Originally, Mars probably had more of an atmosphere, but owing to its lower gravity it probably lost most of its atmosphere. At one time, it most likely had liquid water on the surface, but that is no longer the case.

Does it have weather cycles?

Yes. It has storms with very high winds - hundreds of kilometres per hour. But the winds don't have quite the same force as Earth winds due to the much lower atmospheric pressures. Nevertheless, dust storms are quite common, and there are also "seasons".

Can we compare events on Mars with events on Earth?

The current composition of Earth's atmosphere is largely determined by the actions of lifeforms on the planet. In particular, this accounts for the extremely large abundance of free oxygen. The atmosphere of Mars is quite different.

Obviously, Mars is significantly further from the Sun than Earth, which has also affected its climate in fundamental ways - just as Venus has suffered from being closer to the Sun than Earth.

Currently we seem to be in a high point of the solar cycle. Yes, the Sun is going through a warmer-than-average phase, and this might account for various observations on Mars. But climatologists have considered the Sun's warming as it affects the Earth, and concluded that the current global warming we are experiencing cannot be due solely to a warming of the Sun (as I said in my first post to this thread).

Do we know much about weather conditions on other planets?

Do we know much about weather conditions on other planets?

Yes, a lot.

We can observe the atmospheres of other planets with telescopes. Numerous space probes have also visited all the planets. And we can bounce radar off the planets, and look at infra-red signatures and so on.

In the case of Mars, the weather is extraordinarily well studied, given that spacecraft such as the Mars Explorer and Mars Observer have been orbiting the planet taking pictures and measurements for a number of years now.

cant cure cancer, cant cure aids, cant cure a headache, can make fake cheese. what will the sun be like in 5 billion years? mkay

Can't use an apostrophe.

So how hot is it going to get be the next 200 million years?

http://www.xomba.com/the_suns_future_a_brief_outline

However, from now, in 1100 million years, the Sun's luminosity will be 110% of the present value. In 3500 million years, the Sun's luminosity will become 140% greater than at present.



so in 1.1 bilion years were at a 110% so it proberly won't be more then a 102% in the next 200 million years. So that's from 1370 watts to les then 1400 watts/m².

every word of this thread is bullshit

So what if it is and what if it isn't?

Basicley over the concept of the sun is getting hotter you got 3 sorts of time tabels, the short one it happens in a lifetime, the average one is continental and takes (hundreds) of millions of years and the long one takes astronomical long billions of years.
It's save to say that the increasing temprature of the sun belongs in the later category and really is unimportant unless for some boring study of possible futures.

Kendall-It is hard to say that we are not responsible for the temperature of mars or the sun, giving the give and take systems that are going on in the solar system the greenhouse gases that we are letting out in the atmosphere might be causing the entire solar system to heat up (i'm just thinking outloud) but if the tempature of the sun was geting hotter because of the earth then the other planets would warm up. I do not know why but I always had the idea in my head that the sun was sucking something from the solar system or planets like a form of energy or something that it takes in that is opposite of the radiation(light) it gives off. If it was self suffecient woulden't it get smaller and smaller over time?

Well maybe all the attention is making it blush and feel warm inside. But besides that who argues that Mars is warming up, different then it should.

It does

Kendall-Who took the temp? This is a language I know little of, I do own a telescope and a book on astronomy though.

Could the change in the sun`s magnetoshere due to flip in 2012 be linked to this?

We are really changing the composition of the atmosphere like in an instant according to that report.

In 200 million years it won't matter too much, will it?

http://www.lubbockonline.com/news/092897/study.htmLOL!! So THIS science is right. The 90% plus other scientists are all part of a vast leftwing conspiracy, right??:rolleyes: If Gore had talked about this tiny sliver of opinion science the righties would be INSISTING there is global warming!!!!!!!!!
Republicans and righties: Go work on another gay marriage ban or an English Only law and stay out of the serious topics. Thaaaaanx.

New studies indicate that the sun is growing in solar irradiance and getting hotter adding heat to an Earth already thought to be warming by the Greenhouse effect.This same report was just cited on a thread in the Human Science forum. I first read about this two years ago and have posted in here a dozen times. I'm glad somebody else now believes me.The UN report which is about to be released states categorically that solar fluctuations are not the primary cause of the current global warming trend - it is human caused.The UN? The UN??? You must be kidding if you expect us to accept the authority of the most politicized body on earth! That's like saying you're going to stop taking drugs because the DEA says they're bad for you.

The U.N. wants the people in the industrial world to feel guilty.

I agree that we probably can do something to mitigate the effects of global warming. But making people feel bad is never the way to get them to do their best. Optimistic people always accomplish more.

The Right are who have turned this into a divisive political catfight, not the UN!:p
