Does anyone really know the truth about Global Warming?

Question

What do you think about Global Warming on Mars?

Answer 1

Because of global warming, gradually we will adapt for living on mars(sure it will take some time). Then we can live also on mars.

Answer 2

You can argue it all you like, but I guess it comes down to the question of "What kind of world will we leave for others once we're dead?" if you really care about us as a species, never-mind the rest of the web of life that surrounds/supports us.

  Myself, I'm not so anthropocentric, I think we're neat but not essential to the grand scheme of things, but those who argue most for trashing the planet in the name of profit tend to place humanity at the center of things.

  So how selfish do you want to be?

  & Mars is really irrelevant until we figure out a way to even have people survive the trip to & fro.

Answer 3

anyone who says something like this, obviously doesn't have a clue what science is:

<<Remember, science is NOT about truth. With truth, a lie is the only other alternative. Science is about hypothesis. Until you disprove mine, it works. It is not, however, the truth.>>

That may be what so-called creation science is, but that really isn't science.

We work to disprove the hypothesis, not prove it. And by being unable to disprove it, it becomes accepted.

As far as Mars, we don't know enough about our own climate to say what factors ave what weight on this warming problem we are experiencing, there is no way we will be able to tell that it is occurring on a planet that has an atmosphere so drastically different.

Answer 4

Temperature fluctuations around the globe happen from time to time, totally due to solar activity.  

Same on Mars.

Answer 5

don't move to mars. its hotter there.

and the atmosphere don't have no oxygen.

and if there was water there, it would take millions of years to develop enough oxygen for enough humans to thrive there.

Answer 6

I'm not sure we're to blame for global warming on Earth, but I'm willing to bet we've got nothing to do with Mars and other planets warming. It's not clear why they're warming since the sun's output doesn't seem to have increased.

On Earth one theory is that when the sun's surface is empty of sunspots (as it is today and has been for months), that reflects a weakening of it's magnetic field. That field usually deflects most of the gamma radiation from outside our solar system so it doesn't reach the Earth where it interacts with our atmosphere, forming clouds and causing cooling temps. The Earth has a magnetic field too, which is miniscule compared to that of the Sun. Since Mars has very little atmosphere and no clouds or water vapor, that isn't causing it to warm. We'll eventually find out what is causing it  but right now there's no way to prove any theory.

The theory is that CO2 will cause warming to some extent, that can be proven in a laboratory. The IPCC posits that this is amplified by water vapor in the air which causes more warming. But based on this theory, CO2 warming would trigger more water vapor which causes warming of it's own, heating the oceans which then release more CO2, starting a chain reaction of warming. Since the Earth gets much warmer in summer than in winter and it's never caught fire due to that temp fluctuation, that theory is unlikely. Some warming is from CO2, nearly all is from water vapor and we have only minimal impact on how much water vapor is in the atmosphere.

Answer 7

It makes common sense.  However, common sense also says that plants will flourish with more CO2.  Ask anyone who grows pot plants.

In the seventies we were going to experience a big ice age, now we are going to burn up.

The truth is that climate is very, very, very complicated.

Climate goes through cycles that may last for hundreds of years.

I personally believe GW is happening.  But I also know that my belief is based on hearsay and intuition, not facts.

And this "scientific" issue is really a political one, much more political than the stupid evolution vs. creation bullshit "debate".

The only way to realistically stop GW is curtailment of human activities like growing food, refining water and eating.

So, if we kill all the newborn babies, we could save the earth in time for a giant asteroid to wipe it out.

Answer 8

with religious certainty?  no.

within the realm of scientific consensus?  most certainly.

note that every single reputable scientific body supports the idea that there is a problem that needs to be addressed.

"What do you think about Global Warming on Mars?"

i think it's absolutely irrevelant.

keep in mind, that the sun is cooling slightly.

just as your town gets warmer and cooler throughout the year, so does mars.

get over it, it has no bearing on what's happening here.

it is true that it has been both warmer and cooler on the earth.

it is true that natural cycles cause warming and cooling.

neither of those facts preclude the ability of human activity do alter the environment.

nor do they preclude the abiility of man to fix what he has messed up.

one might take the ozone hole as an example.

it was the result of chemicals released into the atmosphere.

now that we're no longer releasing those chemicals, the problem is being corrected, although quite slowly.

the CO2 problem is much larger, will be more difficult to remedy, will take much longer, and will be more expensive.

that doesn't mean it cannot, or should not, be done.

unless corrective action is taken, you can expect much more civil unrest, like this.

(one might note that there's no mention of sloan or lindzen on MIT's official website of current science.)

as to your comment, "there's no consensus",

<<The global warming scare is promulgated, by, believe it or not, U.S intelligence, in order to fill the void previously filled by the cold war up to the late 1980s.>>

rotflmao  --  omg, it's the vast left wing conspiracy (ie, U.S intelligence, who's under the thumb of cheney, mind you) out to do the country in again.

now i'll most certainly agree that chevron, exxon, the coal industry, etc have many scientists that question AGW.

however, even you cannot think that they're unbiased.

Answer 9

GW is a myth. We as human beings have only been measuring weather and temp for about a hundred years (minuscule time in earths historical standards). Our tech is still of the mark most of the time. Does anyone think we really have an accurate measure of what is really going on? And don't get me started about how higher temps actually lead to ice ages. Sheesh!

Answer 10

Here's a link to ALL the myths of AGW.....

Answer 11

well to answer your question no because there was no debate or anything to prove or disprove either side. But because skeptics can't be heard in todays media they think its proven beyond doubt. I am a skeptic!

Answer 12

Your question might be digging best opinions. It's hotter in Mars and assuming life has existed in this planet, then survival of the fittest is what is or has been going on there. Those creatures who can adapt to a higher temperature were those who survived from the start of change.

Answer 13

linlyons,

>>>note that every single reputable scientific body supports the idea that there is a problem that needs to be addressed.<<<

It is the other way around. No reputable scientific body supports the man-made global warming idea. And not only is this the case, hardly any scientists support it at all.

This is not surprising: CO2 constitutes only 1/18th of 1% of the atmosphere, and man-made CO2 only a tiny portion of that 1/18th of 1%. In other words, CO2 is an extremely rare gas, and man-made CO2 almost non-existent relatively speaking.

The global warming scare is promulgated, by, believe it or not, U.S intelligence, in order to fill the void previously filled by the cold war up to the late 1980s. The U.S needs to police the world, and they cannot do it directly, so they need leverage. The leverage they employ is distraction: keep all nations focussing on one issue together, that way you get to monitor them, and no-one goes off on their own agenda. You also get to set the agenda for the disenchanted lefties who were active with the Soviet stuff until it collapsed, and therefore you make sure they stay visible to intelligence.

If you don't believe me, ask yourself why it is that:

1. An ex-vice president got the job of pushing the idea, yet the country he comes from couldn't care less.

2. Greenies who typically have no money and are flat out feeding themselves from canned food while living in tents on their crusades, who also have no call-centres or central databases, and no access to commercial media, no access to billionaires, no access to CEOs of multi-national corps, and again, NO MONEY, just happen to be able to bring every major corporation in the world to their knees, get their story heard almost every day on every radio station in the entire Western World, get everyone on Answers talking about their ideas, as well as hundreds of other forums world-wide, and this despite a petition of 31,072 scientists to the U.S government to abandon the whole thing. Hmmmm? Don't think there might be someone else pulling the strings given that it has kept on going now for 20 years?

It is U.S intelligence, who give themselves away by their obvious deafening silence on the loudest issue since the A-bomb dropped on Hiroshima.

Answer 14

The planet is cooking and Mars is baked-out.

Answer 15

You sound like  another Big Oil brainwashed lemming. Wake the h**l up foo!

Answer 16

The answer is no, no one "knows" the truth about global warming, let alone average temperature, average sea level, water vapor, convection, or the chaotic nature of forcings.

Climate science is in its infancy.  Some contend that 'climate science' is in fact still  a soft science, much akin to economics and politics.  I would have to concur.  

No ONE person knows climate science.  It is too vast a subject for one scientist to master.

Remember, science is NOT about truth.  With truth, a lie is the only other alternative.  Science is about hypothesis.  Until you disprove mine, it works.  It is not, however, the truth.
