Evidence for NATURAL global warming?

Question

and can you EXPLAIN the evidence? n convey 2 me why it is clear?

Answer 1

There have been natural changes in the past of course.  But the data proves THIS CHANGE is not natural.

It's taken years of work by hundreds of scientists to prove that.  You can't understand it in a few bullet points.  All you can do with those is make unsubstantiated claims that are worth NOTHING.  The proof below is mostly in the links.  It takes real work to understand this, which is why there's a lot of nonsense spouted here.

This is science and what counts is the data, not people's intuition.

"I wasn’t convinced by a person or any interest group—it was the data that got me. I was utterly convinced of this connection between the burning of fossil fuels and climate change. And I was convinced that if we didn’t do something about this, we would be in deep trouble.”

Vice Admiral Richard H. Truly, USN (Ret.)

Former NASA Administrator, Shuttle Astronaut

Here are two summaries of the mountain of peer reviewed data that convinced Admiral Truly and the vast majority of the scientific community, short and long.

There's a lot less controversy about this is the real world than there is on Yahoo answers:

And vastly less controversy in the scientific community than you might guess from the few skeptics talked about here:

http://www.sciencemag.org/cgi/content/fu...

EVERY major scientific organization has issued an official statement that this is real, and mostly caused by us.  The National Academy of Sciences, the American Association for the Advancement of Science, the American Institute of Physics, the American Chemical Society, the American Geophysical Union, the American Meteorological Association, etc.

Answer 2

How the great lakes formed. It was ice that melted after gouging the earth.

What is it that any animal can do that is not natural?

Answer 3

The best evidence is the sun, and sun spots.

The earth warmed .2-.3 deg C by 1940.  Carbon went from 285-290 ppm to 295-300 ppm.  From the IPCC that will have an effect of .0 5 deg C.  Feedbacks due to carbon would be small over that change.  From this we can conclude that about .2 deg C is of natural causes.    

How much of the rest is debatable.  The first temperature reconstructions showed a natural Midevil warm period as hotter than today.  The Hockey stick chart changed that.

Answer 4

Normally global warming and other climate changes are natural.  This time is different.  See the link below for an explanation of how we know this.

Answer 5

Many of the temperatures taken are regional, not global.

Think of the last ice age......

It warmed up. Obviously.

Technically, we are in a stage of GLOBAL COOLING!

Funny, huh?

Except we are in interglaction, which happens around every 100,000 years. Which means the earth warms up.

Though i do agree that we need to stop polluting.

Answer 7

I think the evidence is that the changes that we are experiecing at the moment ( increasing storms worldwide, shortage of water etc ), are happening much faster than they have happened in the past - when these phenomena took thousands and thousands of years to occur.

Scientists who believe climate change is not happening say that what is happening now has always happened. This is probably true, only it took millenia for these changes to occur.

If you think about the amout of forests we cut every year, the amount of green house gases we emit, and the amount of resources we waste, it figures that it´s taking its tall....I think.

Answer 8

Sure. The global warming we are experiencing is not natural--and there is no evidence to the contrary.

Clear enough?
