If recent global warming is part of some natural cycle, then which cycle is responsible?

Question

Climate change is about change; if recent global warming is not related to increasing concentrations of greenhouse gases, then there must be some evidence that some other change is responsible for recent global warming.

Please don’t respond unless you can source your answer to a scientific article, preferably one published in peer-reviewed literature. I am not interested in opinions and editorials, I want scientific sources.

Answer 1

Mostly solar insolation modified by El Nino/La Nina.

The site below presents a well-referenced (so you get your scientific sources), lucid argument showing that

1) CO2 is not a good predictor of global temperature

and

2) solar insolation as modified by El Nino/La Nina is a good predictor.

It is very well done.  I recommend reading the entire site.  (It's not that big a site)

Answer 2

Hmmm...let me thin about this one......how about THE SUN?

This blog references the studies used.

Not a journal or scientific, but a cool site with shots of the sun over 10 years.

And by the way, when you say peer reviewed, are you referring to the excellent job reviewers did to the Hockey Stick data before it was published in the IPCC report?

Look at the links next time. The sun is a much better match to temperature than CO2. But, who would ever think of that?

Notice the correlation in this report.

Answer 3

It's a part of this cycle:

I don't have the answer to it's cause...but any explanation would need to account for every OTHER peak and valley of this cycle to be a valid argument.  Since life on this planet has changed drastically over the time frame in question, I'd begin my search for a cause with the sun.

Edit:  Horse, meet water.  Water, horse....

Answer 4

I do remeber something in the news, one of global warmings factors is that there is that there is an underwater volcano somewhere in antarctica.

Answer 5

It is true that CO2 is higher now than it has been the past 100 or so years. Why is it then that the highest temperatures were recorded in the 1930's but CO2 was only half of what it is now. There is no cause and effect relationship between the two. If that were the case then the highest temperatures would be now. The past year it was actually colder than it has been in over 100 years. There is however a positive correlation between solar activity and temperature. Solar activity was actually at its highest in the 1930's when it was the hottest on record. Imagine that, the Sun actually has something to do with temperature. Who would of thought?

Answer 6

This is the easiest question I've answered yet. I wouldn't waste my time, if you lack environmental understanding.You really have to go to school for this but here's the basic gist.

Answer 8

I just finished watching a program where the scientist were talking about global cooling,which seems more convincing then the warming theory.To find out more about what your looking for try searching Google.

Answer 9

Ok I won't respond.

Answer 10

Mayan Solar Cycle, end 2012

Answer 11

It's not the sun. Excerpt from the National Academy of Sciences...

"Rising temperatures and greenhouse gas

concentrations observed since 1978 are particularly

noteworthy because the rates of

increase are so high and because, during the

same period, the energy reaching the Earth

from the Sun has been measured precisely by

satellites. These measurements indicate that

the Sun’s output has not increased since 1978,

so the warming during the past 30 years cannot

be attributed to an increase in solar energy

reaching the Earth."
