True or false there is the same likely hood that global cooling will take place rather than global warming?

Please leave a somewhat detailed opinion on why you think that.

false because Global cooling doesnt even exist yet o.O at leas ti havent heard of it o.o

What do i win? o.O

well since no one else is saying anything I'll just explain


Mars' atmosphere is made up of 95% Co2 and its temperature is averaged at -67 degrees F. So with that being said they say that the Co2 going in to our atmosphere is warming our planet. Which is false, even in the polls they show that show warming it also shows some cooling no matter how much they try to skew it to look like its only warming. The station where they take the whole planets Co2 atmospheric lvl (which is around360 PPM) is on top of a volcano in Hawaii. They also have stations that measure the temperature which are all placed in major airports and parking lots. Which of course would only show it warming because of the activity. Scientists have been doing independent studies where they put stations in places where that have less human activitly and it shows that the temperature is actually declineing even during the summer months. So with the evidence presented you could easily say that the planet Earth has the same chance to cool rather than warm.

K so mars atmosphere maybe 95% co2 but do you know how thin it is? Also factor in the distance from the sun.

Mars atmosphere is roughly 100 times thinner than the Earths and agreed about the distance from the sun. However, The fact is cooling is defeintly a possibility as well.

1. when atmospheric CO2 reacted with surface rocks and water to form a solid carbonate mineral
2. when impacts from asteroids or comets blew away the atmosphere
3. when the solar wind stripped away the upper atmosphere

This is how it happened to Mars, Which could happen to Earth as well.

It could yes, but with a low probability that it will reverse the warming trend completely. Also don't forget about Venus it is a prime example of runaway green house effect.

Well on any chart that you look at that shows warming you will see trends of cooling as well so you can't say from a scientific stand point that there is just a warming trend. Agreed on Venus, but the percentile for that happening is low as well.

lol lies the next thing under water vapor in our athmosphere is Co2 so I dont know where you get your inoformation but you may want to look into it a bit more

Yeah, i never meant to imply that there is only a warming trend. I was just stating i don't see this warming trend completely reversing itself as you described.
