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

Question

Ice caps are melting on both Earth and Mars. According to one researcher's controversial theory, this suggests that global warming has nothing to do with humankind.

Answer 1

hardly conclusive and yet another desperate attempt to defy reality. Tis best to err on the side of caution and change our current practices than continue the way we are going polluting our waters, land, and air.

If we do not, those generations who survive in the coming generations will despise us and particularly the attitudes of the asker for doing nothing.

Answer 2

has it ever been stated that global warming is NOT a "natural" phenomenon? It's only been enhanced by the wreckless of man, but the ice ages are a natural cycle directly related to global warming.

As the avg air temp warms, it melts the ice caps, thus cooling the oceans, thus bringing on an ice age, thus adding mass b/c there is less water etc..
it's cyclical..

and to truth seeker: that's the point, there are no humans on Mars, even though mars is going through a period of ice melting. Perhaps what can be taken from that is that the sun in general is getting warmer..

Answer 3

worldwide warming and cooling, alongside with climate substitute, have been happening because of fact the earth shaped some billion years in the past. In that experience, this is not a lie and could continuously be fact. The almighty question that has plagued our media for the previous couple many years is regardless of if anthropogenic (human) outcomes interior the international (a.ok.a., greater quantities of CO2 and different pollutants) has carry approximately greater warming (hence) and climate substitute. there is sufficient medical information in all forms of medical magazine articles to assist the two sides of the argument. in spite of the actuality that all of us is of an analogous opinion that CO2 ranges have long gone up, some have faith that this has carry approximately an surprisingly warmer globe on an analogous time as others have faith that the warming happens first and CO2 in simple terms follows. interior the latter case, the starting to be ranges of CO2 may be much less thank you to people and the warming could in simple terms be labelled as 'commonly of course-led to' (because of image voltaic storms, etc). The technological know-how can and already has supported the two sides of the fence. The media alongside with politics look to have jumped on the anthropogenic argument bandwagon, on an analogous time as there's a stream by potential of a few scholars (and others) to the two refute this thought or to a minimum of know that we in simple terms don't be attentive to! what's definite is that we are emitting and producing various pollutants on a daily basis and that it somewhat is not sustainable. yet another fact is that people have long gone far previous what the earth can sustainably help, the two in terms of our inhabitants many times and our guy or woman and collective impacts. in this know, worldwide warming and climate substitute might (if anthropogenic) purely be a symptom of a good greater situation. regrettably, much less interest is payed to this somewhat specific root of the international's situation.

Answer 4

So are you telling me that the smog in LA is good for the atmosphere? Or perhaps if you researched for both sides of the subject and took a look at London before and after cleaning up after themselves, you might have a change of heart.

Answer 5

Fact is that global warming will continue if we make it worse or not. The alternative is another Ice Age.

Answer 6

I'm not sure why it matters. The way we live can't be good for us. Emissions has been greatly reduced where I live-and there are still days it's not healthy to go outside. How can that be good for us? And it's win-win to reduce our dependency on oil! What are people arguing about?

Answer 7

If this guy is head of an Astronomical Observatory - he's probably an astronomer. Hardly qualified to make judgments about climate science.

Answer 8

There are NO people living on Mars. How does anything to do with Mars suggest anything about global warming?????

Answer 9

YUP! (Finally... someone with some common sense!)

Answer 10

But, but, but Al Gore said.......
