So...

... who are the men on Mars...

... `causin' climate change there?

It's probably all the microwaves from stupid ideas flowing from the Earth to Mars.....

Scientists find evidence of global warming on Mars
Tuesday, May 31, 2016 - Earth isn’t the only planet grappling with climate change, although this other orb doesn’t have much in the way of fossil fuel emissions or a 97 percent of scientific “consensus” on global warming. Newly published evidence suggests Mars is experiencing global warming as it emerges from an ice age.

The red planet, which moved closer to the Earth on Monday than at any other time since 2005, has retreated from a glacial period that would have covered large areas in white before the thaw about 370,000 years ago, according to a study published Friday in the journal Science. The research was conducted using an instrument on board the NASA Mars Reconnaissance Orbiter that allowed an unprecedented examination of “the most recent Martian ice age recorded in the planet’s north polar ice cap,” according to a NASA press release. Research was led by planetary scientist Isaac B. Smith at the Southwest Research Institute in Boulder, Colorado. “We found an accelerated accumulation rate of ice in the uppermost 100 to 300 meters of the polar cap,” Mr. Smith said in a statement on the SRI website. “The volume and thickness of ice matches model predictions from the early 2000s. Radar observations of the ice cap provide a detailed history of ice accumulation and erosion associated with climate change.”

Mars experiences seasons as does the Earth, resulting in the advance and retreat of carbon dioxide ice and snow over the poles during the Martian year. But the red planet also undergoes larger variations over thousands of years that result in “substantial shifts in the planet’s climate, including ice ages,” said the NASA Mars Exploration statement. NASAattributed the changes to the planet’s orbit and significant tilt. “Earth has similar, but less variable, phases called Milankovitch cycles,” said NASA. “On Earth, ice ages take hold when the polar regions and high latitudes become cooler than average for thousands of years, causing glaciers to grow toward the mid-latitudes,” said NASA. “In contrast, the Martian variety occurs when — as a result of the planet’s increased tilt — its poles become warmer than lower latitudes.” Water vapor moves toward the planet’s equator and forms ice and glaciers at mid-latitudes, said NASA. “As the warm polar period ends, polar ice begins accumulating again, while ice is lost from mid-latitudes. This retreat and regrowth of polar ice is exactly what Smith and colleagues see in the record revealed by the [Shallow Subsurface Radar] images,” said NASA.

While models have predicted the occurrence of ice ages on Mars, “evidence has been scant,” Science said in its description of the study, “An Ice Age Recorded in the Polar Deposits of Mars. “The layers in the upper few hundred meters display features that indicate a period of erosion, followed by a period of rapid accumulation that is still occurring today,” said Mr. Smith. Speculation about climate change on Mars has heightened since 2001 photographs from the Mars Global Surveyor suggested that ice caps near the planet’s South Pole were receding. A 2007 study by Russian physicist Habibullo Abdussamatov concluded that the caps had been in decline for three summers in a row and attributed the decline to solar irradiance. The question of whether Mars is experiencing climate change has spilled into the global warming debate on Earth, fueling discussion over whether both planets are heating up as a result of solar activity.

The consensus view is that the warming trend on the planets is coincidental and that climate change on Earth can be attributed primarily to increased greenhouse-gas emissions in the atmosphere. “Mars and Earth wobble in different ways, and most scientists think it is pure coincidence that both planets are between ice ages right now,” National Geographic News said in a 2007 article. Mr. Abdussamatov has disputed that explanation. “Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance,” he told LiveScience in 2007. In 2014, Kentucky state Sen. Brandon Smith pointed to evidence of warming on Mars as evidence that global warming is being driven by factors other than carbon dioxide emissions, prompting ClimateProgress to declare that “there is absolutely no scientific evidence that one sole instance of melting [on Mars] is the result of a planet-wide trend.” Mars came within 48.6 million miles of Earth at 5:34 p.m. EDT Sunday when Mars and the sun lined up on opposite sides of Earth. The next close encounter is projected for 2018, when Mars is expected to come within 35.8 million miles of Earth, NASA reported.

Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says
February 28, 2007 - Simultaneous warming on Earth and Mars suggests that our planet's recent climate changes have a natural—and not a human-induced—cause, according to one scientist's controversial theory.

Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere. Mars, too, appears to be enjoying more mild and balmy temperatures. In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a row.

Habibullo Abdussamatov, head of space research at St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun. "The long-term increase in solar irradiance is heating both Earth and Mars," he said.

Solar Cycles

Abdussamatov believes that changes in the sun's heat output can account for almost all the climate changes we see on both planets. Mars and Earth, for instance, have experienced periodic ice ages throughout their histories. "Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance," Abdussamatov said. By studying fluctuations in the warmth of the sun, Abdussamatov believes he can see a pattern that fits with the ups and downs in climate we see on Earth and Mars. Abdussamatov's work, however, has not been well received by other climate scientists.

such information will be ignored and outright rejected by the global warming faithful's

u see according to them the whole solar system warming is natural

except for here on earth where industrialist pigs such as you and i are responsible

but then again that only applies to those in the United States

other countries that give off more like China for example dont count

Not many

Some of the leading physicists and astrophysicists of today have come out against this global warming agenda. If they are against it that would suggest to me that there's a whole lot more where they came from.

Well actually there's a lot of difference.

The best example I can give of human interference messing things up is Mao killing all the birds because they ate the crops, only to find out that the insects the birds ate, would eat the crops more than the birds.

There's a natural climate change. Animals have developed within these limits of the more stable climate over the past 400,000 years or so. We as humans have really taken off over the last few thousand years or so, but we've survived the last 100,000 years and developed. Things go up and they go down. We've probably hit our NATURAL warm peak a while ago.

The problem with MAN MADE warming is that, like Mao, we don't really know the consequences of our actions.

The first thing is that we're pumping lots of greenhouse gases into the atmosphere and the world is doing quite a good job of dealing with them. Sort of.

However the seas and oceans are taking the brunt of this. The PH levels of the seas are changing, killing marine life. Killing marine life TOO QUICKLY for it to be able to adapt to its new world. Natural warming and cooling might kill of some species, but it doesn't endanger the whole damn ecosystem.

Now, what happens if the oceans stop taking in the CO2 we're pumping up there? Well, it could happen if the PH levels kill most of the marine life and everything else dies because the food chain has collapsed. Then there's nothing in the oceans left to take in the CO2. Even worse than this would be that the oceans start to pump out the CO2 it's already been taking in. The oceans are BIG and there's a LOT of CO2 there. A massive outpouring of CO2.

There are plenty of possibilities out there. Scientists are studying the effects, studying the difference between their predictions and what is actually happening. All the while the right is pretending they know everything when they know nothing, and something bad could, potentially happen that makes life difficult for humans to live on this planet.

All the while the right is pretending they know everything when they know nothing, and something bad could, potentially happen that makes life difficult for humans to live on this planet.

My point was that regardless of the cause, the effects are the same. If a natural plague killed Mao's birds the insects would still have eaten the crops. There are really two parts of this issue: the causes of climate change and the effects of climate change. Mitigating the man-made causes would be the low-hanging fruit, increase auto efficiency, switch from coal to gas, etc. Dealing with the effects of sea level rise will be VERY difficult and VERY expensive, building vast levee systems, moving existing cities, etc.

The first thing is that we're pumping lots of greenhouse gases into the atmosphere and the world is doing quite a good job of dealing with them. Sort of.

However the seas and oceans are taking the brunt of this. The PH levels of the seas are changing, killing marine life. Killing marine life TOO QUICKLY for it to be able to adapt to its new world. Natural warming and cooling might kill of some species, but it doesn't endanger the whole damn ecosystem.

Now, what happens if the oceans stop taking in the CO2 we're pumping up there? Well, it could happen if the PH levels kill most of the marine life and everything else dies because the food chain has collapsed. Then there's nothing in the oceans left to take in the CO2. Even worse than this would be that the oceans start to pump out the CO2 it's already been taking in. The oceans are BIG and there's a LOT of CO2 there. A massive outpouring of CO2.

There are plenty of possibilities out there. Scientists are studying the effects, studying the difference between their predictions and what is actually happening. All the while the right is pretending they know everything when they know nothing, and something bad could, potentially happen that makes life difficult for humans to live on this planet.

My point was that regardless of the cause, the effects are the same. If a natural plague killed Mao's birds the insects would still have eaten the crops. There are really two parts of this issue: the causes of climate change and the effects of climate change. Mitigating the man-made causes would be the low-hanging fruit, increase auto efficiency, switch from coal to gas, etc. Dealing with the effects of sea level rise will be VERY difficult and VERY expensive, building vast levee systems, moving existing cities, etc.

Yes, but the point I'm making is that the consequences of something natural are the consequences of life on this planet. Life has adapted to the Earth and seems to be able to survive. If it can't, then it can't, that's life.

But to actually go around killing your own planet out of sheer ignorance is something quite different.

Here's my analogy. Jumping off a very high cliff into the sea.

The right on man made climate change are like "hey, I'm going to jump off the cliff", the left are like "but there might be rocks at the bottom that will kill you", the right say "no, there are no rocks, I know, because it's convenient for me that there are no rocks"

Yes, but the point I'm making is that the consequences of something natural are the consequences of life on this planet. Life has adapted to the Earth and seems to be able to survive. If it can't, then it can't, that's life.

Cold comfort to the dinosaurs that the comet was natural. Some of us have children that we'd like to see thrive regardless of the cause of global warming.

Scientists find evidence of global warming on Mars
Tuesday, May 31, 2016 - Earth isn’t the only planet grappling with climate change, although this other orb doesn’t have much in the way of fossil fuel emissions or a 97 percent of scientific “consensus” on global warming. Newly published evidence suggests Mars is experiencing global warming as it emerges from an ice age.

The red planet, which moved closer to the Earth on Monday than at any other time since 2005, has retreated from a glacial period that would have covered large areas in white before the thaw about 370,000 years ago, according to a study published Friday in the journal Science. The research was conducted using an instrument on board the NASA Mars Reconnaissance Orbiter that allowed an unprecedented examination of “the most recent Martian ice age recorded in the planet’s north polar ice cap,” according to a NASA press release. Research was led by planetary scientist Isaac B. Smith at the Southwest Research Institute in Boulder, Colorado. “We found an accelerated accumulation rate of ice in the uppermost 100 to 300 meters of the polar cap,” Mr. Smith said in a statement on the SRI website. “The volume and thickness of ice matches model predictions from the early 2000s. Radar observations of the ice cap provide a detailed history of ice accumulation and erosion associated with climate change.”

Mars experiences seasons as does the Earth, resulting in the advance and retreat of carbon dioxide ice and snow over the poles during the Martian year. But the red planet also undergoes larger variations over thousands of years that result in “substantial shifts in the planet’s climate, including ice ages,” said the NASA Mars Exploration statement. NASAattributed the changes to the planet’s orbit and significant tilt. “Earth has similar, but less variable, phases called Milankovitch cycles,” said NASA. “On Earth, ice ages take hold when the polar regions and high latitudes become cooler than average for thousands of years, causing glaciers to grow toward the mid-latitudes,” said NASA. “In contrast, the Martian variety occurs when — as a result of the planet’s increased tilt — its poles become warmer than lower latitudes.” Water vapor moves toward the planet’s equator and forms ice and glaciers at mid-latitudes, said NASA. “As the warm polar period ends, polar ice begins accumulating again, while ice is lost from mid-latitudes. This retreat and regrowth of polar ice is exactly what Smith and colleagues see in the record revealed by the [Shallow Subsurface Radar] images,” said NASA.

While models have predicted the occurrence of ice ages on Mars, “evidence has been scant,” Science said in its description of the study, “An Ice Age Recorded in the Polar Deposits of Mars. “The layers in the upper few hundred meters display features that indicate a period of erosion, followed by a period of rapid accumulation that is still occurring today,” said Mr. Smith. Speculation about climate change on Mars has heightened since 2001 photographs from the Mars Global Surveyor suggested that ice caps near the planet’s South Pole were receding. A 2007 study by Russian physicist Habibullo Abdussamatov concluded that the caps had been in decline for three summers in a row and attributed the decline to solar irradiance. The question of whether Mars is experiencing climate change has spilled into the global warming debate on Earth, fueling discussion over whether both planets are heating up as a result of solar activity.

The consensus view is that the warming trend on the planets is coincidental and that climate change on Earth can be attributed primarily to increased greenhouse-gas emissions in the atmosphere. “Mars and Earth wobble in different ways, and most scientists think it is pure coincidence that both planets are between ice ages right now,” National Geographic News said in a 2007 article. Mr. Abdussamatov has disputed that explanation. “Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance,” he told LiveScience in 2007. In 2014, Kentucky state Sen. Brandon Smith pointed to evidence of warming on Mars as evidence that global warming is being driven by factors other than carbon dioxide emissions, prompting ClimateProgress to declare that “there is absolutely no scientific evidence that one sole instance of melting [on Mars] is the result of a planet-wide trend.” Mars came within 48.6 million miles of Earth at 5:34 p.m. EDT Sunday when Mars and the sun lined up on opposite sides of Earth. The next close encounter is projected for 2018, when Mars is expected to come within 35.8 million miles of Earth, NASA reported.

Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says
February 28, 2007 - Simultaneous warming on Earth and Mars suggests that our planet's recent climate changes have a natural—and not a human-induced—cause, according to one scientist's controversial theory.

Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere. Mars, too, appears to be enjoying more mild and balmy temperatures. In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a row.

Habibullo Abdussamatov, head of space research at St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun. "The long-term increase in solar irradiance is heating both Earth and Mars," he said.

Solar Cycles

Abdussamatov believes that changes in the sun's heat output can account for almost all the climate changes we see on both planets. Mars and Earth, for instance, have experienced periodic ice ages throughout their histories. "Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance," Abdussamatov said. By studying fluctuations in the warmth of the sun, Abdussamatov believes he can see a pattern that fits with the ups and downs in climate we see on Earth and Mars. Abdussamatov's work, however, has not been well received by other climate scientists.

Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says

such information will be ignored and outright rejected by the global warming faithful's

u see according to them the whole solar system warming is natural

except for here on earth where industrialist pigs such as you and i are responsible

but then again that only applies to those in the United States

other countries that give off more like China for example dont count

We know eventually the world will be uninhabitable. Do you prefer 5000 years from now or 5 million? Do you prefer by our doing or Mother Nature?

Who knows how the martians went out

you have absolutely no proof of any of that dim wit

Not true. I can't find it now but I read last week where scientists put in all the information into a computer and they know how long the world will last. If we end it ourselves it could be 5000 years from now but if we went green like Avatar it could be millions of years.

Who knows if the Martians prematurely killed themselves off or if it happened naturally.

I wonder if they warred with each other rather than build a ship they could live on until earth became habitable.

Ok pal, you argue with the scientists like you rwnj's always do.

Scientists at the University of East Anglia have made their best estimate for how much longer the Earth will be habitable for human life, barring nuclear war, rogue asteroids, or being destroyed to make room for a hyperspace bypass. Fortunately, you don't need to put your affairs in order any time soon. The researchers estimate that the Earth will remain habitable for another 1.75 to 3.25 billion years.

Their research, which has been published in the journal Astrobiology, is part of the bigger project of looking for life outside of our own solar system. Over the past few years, astronomers have discovered a number of planets that exist within the habitable zones of their stars - meaning that their orbits place them not too far, but not too close, so that temperatures on the surface are just right for life to develop.

But with so many planets in potentially habitable zones, there has to be some priority in trying to determine which planets are most likely to contain life and are therefore more worth devoting additional resources to observing. That's where this research comes in.

Since life took hundreds of millions of years to evolve on Earth, the researchers reason that the best candidates for observation are those with the longest habitable zone lifetimes.


The researchers then studied 34 planets, including Earth, that are thought to exist within the habitable zones of their stars. They then used observations of their orbits and their stars' to arrive at estimates of each planets habitable zone lifetime. There is an astounding range of possibilities - ranging "from significantly less than that of Earth to over five times Earth's HZ lifetime," they wrote.

See, if it were up to you we wouldn't even do this research and we would never learn anything. Just like the Martians.

so far all models have been proven wrong

why would this one be any different

making a model is not research

it is guess work at best

 

[sealybobo]

The actual HZ lifetime of any given planet is unlikely to be controlled solely by planetary surface temperatures, and individual worlds may experience a variety of divergent (bio)geochemical evolutionary histories, possibly resulting in markedly different planetary environments to that of Earth."

First step it may be, it's still a fascinating one. As the models for habitability get further defined, that may help astronomers find another planet with life that much sooner. Additionally, this research reminds us that though the end may be billions of years away, the ability of the Earth to remain home for human beings won't last forever.

Let the adults and scientists talk. You go back to making your mud cakes.

But if humans are still around when the Earth begins to move out of the habitable zone, we can always move next door.

"If we ever needed to move to another planet, Mars is probably our best bet," lead researcher Andrew Rushby said in a statement. "It’s very close and will remain in the habitable zone until the end of the Sun’s lifetime - six billion years from now."

I didn't know Mars was still considered to be in the habitable zone. I guess if it has an atmosphere and water maybe it is. And maybe there is life on it still.

But don't ask Jon because he's very negative and seems to think he already knows the answers.

Fucking debbie downer. LOL.

Sure we could be wrong Jon but we won't know unless we try. You say why bother trying. You don't like models. You don't BELIEVE science. I find that laughable. Who the fuck are you Jon?
