How many times has the earth warmed since it was formed?

Answer 1

According to left wing loonies, just since WWII.

Answer 2

Don't know, but I do know that there was a medieval warm period, followed by a “little ice age.” The medieval warm period was from the time of the Roman Empire to about 1300 AD. The “little ice age” was from about 1300 to about 1850. The earth has been warming ever since. The History Channel did a program on this. Quite interesting and I recommend watching it.

Answer 3

It did after the last ice age, and that lead to the demise of the larger mamalian species, and we emerged dominant species because we could adapt.

Now, however, we would be going through a cooling-off period (adjusting for other atmospheric modifiers and solar activity) if it weren't for our emissions of CO2 and the resulting thawing of permafrost and corresponding methane release. Instead, things are heating up rapidly from the standpoint of biolical history, and that's our own doing as a species. There is a real chance that we could reach a tipping point where global warming becomes run-away global warming, and then we're probably all toast as a species. But we can adapt and change and survive if we chose to do so.

Now, Yosemite could blow, cover 3000 square miles 3 feet deep in ash, and dump so much SO2 into the air that the whole planet cools for decades, and then we'd be looking at a really big problem we couldn't do anything about that ends the same way.

All we can worry about is what we can control. If something else we cannot adapt to suddenly happens, that's something totally different than the present Global Warming problem, but the science is the same: things you put into the air (and we're talking millions of tonnes per year here) affect global temperatures and can make the planet less than habitable.

Answer 4

How many times the earth has warmed up: Many times

How many times has the Earth warmed up at such a pace:a couple times

How many times has the rate of change of change of temperature at this level (no, not a typo): Every time there has been a mass extinction. Perhaps five, and only caused by globally catastrophic events (really big asteroids). And it's happening now. The last time I checked, there haven't been any recent 5km astroids for quite awhile. We're the only suspects for this.

So go read a Calculus text book, a Physical science text book, and THEN make a judgment about Global warming.

Answer 5

I don't know but last February National Geographic ran an article stating that the same amount of warming has been observed on Mars and Ganymede. This solar system is getting hot. I think our greenhouse gases are affecting the other planets and moons of other planets.

Answer 6

I'm guessing at least once, since the Earth used to be covered in ice. But I'm sure humans were responsible for that, too.

Answer 7

It warms about once per year since it's been formed.

Answer 8

Many times, however, the cycles have usualy taken thousands to tens of thousands of years. For the polar Ice caps to melt in only a century or two, something un-natural has to be happening.

Answer 9

Irrelevent.

What matters is that it is happening now, and we humans are here.

Whether we are causing it or not does not matter.

If we don't take steps to control it, and soon, we are doomed ot a very horrible future or perhaps no future at all.

That is the simple, sad truth, regardless of what the shills who claim otherwise tell the ignorant, often poorly educated, allways gullible fools who fall for their lies.

Answer 10

Since the beginning of continous weather recording, once.

PS:
How many times per day do you fail to hit the proper rubric?
Would it be too difficult for your troll yesmen to find you there?

Answer 11

Every spring? I don't know actually, cause I haven't really studied Geology.
