Ice melting at a faster rate

[alan1]

No, we can only conclude that climates change.

Exactly

What is causing this warming is another question.

Well, today, man is the one being blamed.

being blamed and actually being the culprit are two different things.

being blamed and actually being the culprit are two different things.

Yes they are.
And absolute proof is even harder to come by.
It's so much easier to just blame.
I wonder what the animals did in the last ice age?
Whom did they blame?
Was it mans fault for not producing enough greenhouse gasses?

There is plenty of proof, and the problem gets more serious every day.

Mars is Melting
The south polar ice cap of Mars is receding, revealing frosty mountains, rifts and curious dark spots.

Listen to this story via streaming audio, a downloadable file, or get help.

August 7, 2003: It's not every day you get to watch a planetary ice cap vanish, but this month you can. All you need are clear skies, a backyard telescope, and a sky map leading to Mars.

this is proof that aliens are driving cars on mars

That article is 5 years old and is about Mars.

Nice deflection though.

The environment is one of my liberal sift spots and I completely support taking steps to be responsible keepers of this planet. However, common sense and rational conclusions and choices must prevail. The radicals on each end of this debate IMO are dangerous. As they are on most issues.

so,,,what's your point... explain it then ..what could it possible be if not a alien car exhaust

 

[editec]

Yup, And if we believe the doom and gloom crowd the North and South Pole should already be deserts, How many years in a row can the ice be melting even faster before someone asks, "wait, how much Ice is up there?"

Good question..the short answer is a lot...a whole lot

How much ice is on Antarctica?

Visualize a mountain range that is more than 800 miles (1300 km) long and 9,900 feet (3,000 meters) high. That’s twice as long as California’s Sierra Nevada and eight times higher than the Empire State Building. Now imagine it completely covered by an ice plateau—you could walk right over the top of this mountain range without even knowing it was there! You would need a lot of ice to cover a mountain range that big. This isn’t just an imaginary mountain range, however, it exists in Antarctica and is covered completely with ice. There are also several other massive mountain ranges in Antarctica with only isolated peaks and rock cliffs poking out from the ice dome that covers most of Antarctica. In some places in Antarctica the ice is more than 13,200 ft (4,000 meters) thick. That’s two and a half miles deep, or more than ten and a half times taller than the Empire State Building.

How much ice is on Antarctica?

The Antarctic Ice Cap contains about 85% of the world’s ice, which is about 80% of all the fresh water on earth. That ice weights about 27 million billion tons (24,500 million billion kg). It’s difficult to conceptualize a number that large. It might help to imagine 100,000 tons, the weight that could be carried by a container ship 335 meters long and 43 meters wide, one of the largest cargo ships on the ocean. If you loaded all the ice on Antarctica onto these cargo ships and then starting counting the ships, assuming you could count one ship per second, you would still be counting more than 860 years from now. The massive weight of the ice cap pushes the underlying continent about 3,300 feet (1,000 meters) into the earth’s crust.

Greenlands Ice?

The Greenland Ice Sheet is a vast body of ice covering 1.71 million km², roughly 80% of the surface of Greenland. It is the second largest ice body in the World, after the Antarctic Ice Sheet. The ice sheet is almost 2,400 kilometers long in a north-south direction, and its greatest width is 1,100 kilometers at a latitude of 77° N, near its northern margin. The mean altitude of the ice is 2,135 meters.[1] The thickness is generally more than 2 km (see picture) and over 3 km at its thickest point. It is not the only ice mass of Greenland - isolated glaciers and small ice caps cover between 76,000 and 100,000 square kilometers around the periphery.

Northern Polar oceanic icepack?

Earth's north pole is covered by floating pack ice (sea ice) over the Arctic Ocean. Portions of the ice that don't melt seasonally can get very thick, up to 3–4 meters thick over large areas, with ridges up to 20 meters thick. One-year ice is usually about a meter thick. The area covered by sea ice ranges between 9 and 12 million km².

Climate myths: Mars and Pluto are warming too - environment - 16 May 2007 - New Scientist

There have been claims that warming on Mars and Pluto are proof that the recent warming on Earth is caused by an increase in solar activity, and not by greenhouse gases. But we can say with certainty that, even if Mars, Pluto or any other planets have warmed in recent years, it is not due to changes in solar activity.

The Sun's energy output has not increased since direct measurements began in 1978 (see Climate myth special: Global warming is down to the Sun, not humans). If increased solar output really was responsible, we should be seeing warming on all the planets and their moons, not just Mars and Pluto.

Our solar system has eight planets, three dwarf planets and quite a few moons with at least a rudimentary atmosphere, and thus a climate of sorts. Their climates will be affected by local factors such as orbital variations, changes in reflectance (albedo) and even volcanic eruptions, so it would not be surprising if several planets and moons turn out to be warming at any one time.

However, given that a year on Mars is nearly two Earth years long, and that a year on Pluto lasts for 248 Earth years, it is rather early to start drawing conclusions about long-term climate trends on the outer bodies of the Solar System.

What do we know? Images of Mars suggest that between 1999 and 2005, some of the frozen carbon dioxide that covers the south polar region turned into gas (sublimated). This may be the result of the whole planet warming (see Mars images hint at recent climate swings).

Dwarf planet
One theory is that winds have recently swept some areas of Mars clean of dust, darkening the surface, warming the Red Planet and leading to further increases in windiness - a positive feedback effect (see Dust blamed for warming on Mars).

There is a great deal of uncertainty, though. The warming could be a regional effect. And recent results from the thermal imaging system on the Mars Odyssey probe suggest that the polar cap is not shrinking at all, but varies greatly from one Martian year to the next, although the details have yet to be published.

Observations of the thickness of Pluto's atmosphere in 2002 suggested the dwarf planet was warming even as its orbit took it further from the Sun. The finding baffled astronomers at the time, and the cause has yet to be determined.

It has since been suggested that this is due to a greenhouse effect: as it gets closer to the sun Pluto may warm enough for some of the methane ice on its surface to turn into a gas. This would cause further warming, which would continue for a while even after Pluto's orbit starts to take it away from the Sun.

It is the billions of tons of methane,now being released from the depths of the Artic and antartic oceans, and from the worlds oceans in general.That is accelerating the already accelerated "Earth cyclical climate change."

Did GHG's either cause (or reverse) the Younger Dryas?


The Earths average temperature has both decreased and increased without man being the cause.

Logically, if we have scientific proof that these climate shifts have occurred many times without the introduction of mankinds impact, then we can conclude that climate shifts have a root cause other than man.

The Younger Dryas was caused by the adrupt cessation of the thermohaline circulation. The cause of this cessatiion was a rapid decrease in salinity of the Northern Atlantic and Artic Oceans. This has been hypothesized to have been caused by the release of a huge amount of water from the Eastern section of the North American ice cap. Causes for that have ranged from a dammning, such as created the Bretz Floods and Lake Missoula, to an impact that created a very rapid melting. Whatever caused the influx of fresh water into the Northern Oceans created a very rapid change in climate.

However, because neither man's actions nor CO2 had anything directly to do with that 1300 year return to the ice ages, that does not change the fact that the GHGs that we have put into the atmosphere is changing the climate at this time. As I pointed out before, this is not the first period that has seen a rapid increase in GHGs. This is just the first time that the increase has been caused by man.

While you are a bit premature, we are still causing more change by the CO2 that we have created using fossil fuels, that may well change in the not too distant future. For the CH4 that you speaking of is the elephant in the room. Once it starts going, mankind is just along for the ride.

The precentage of CO2 in the Amospherelies closer to zero than it does to .1 percent.

To warming caused by CO2 is limited to about 1degree celsius most of which we have already experienced because of CO2's limited ability to block the light spectrum.
