Networks of 7,000 universities declare climate emergency

That link I posted earlier discussed El Nino pretty thoroughly.

Explaining Climate Change and El Nino | Climate Tracker

El Nino events are increasing in both intensity and frequency, resulting in increased extreme weather events. In the recent past, Sri Lanka has experienced very hot weather, with certain regions reaching record temperatures, and we have also had very high precipitation.

These extreme events would cause severe damage to agricultural crops thereby depriving farmers of a stable income. Fishermen would also face a grave situation when heavy precipitation prevents them from going to sea. Natural disasters such as floods and landslides would become more frequent leading to loss of lives and property, as we saw very recently. Other consequences include spread of diseases, road obstructions, hike in food prices and damage to infrastructure.

Climate change cannot be prevented, but its impacts can be reduced. It’s high time we became more environmentally conscious because there may come a day when the climate may change so drastically that this planet would no longer be inhabitable.
El Nino events are cyclic, and we really do not know all the contributing cycles, or we would be better at predicting them.

El Nino's are weather events, not climate.
Climate change regardless of cause is occurring, and is superimposed on top of much larger ENSO cycling.

NASA, using NOAA studies, probably has the most thorough El Nino explanation available. They are very clear in stating that climate change is not responsible for El Nino. However they also talk about the severity being based on warmer accumulated ocean temperatures, and higher ocean level. Both the warmer ocean temps and higher levels happen naturally in the Pacific. That said, overall ocean temperature is rising, and sea levels are rising. So there is undoubtedly some connection between climate change and El Nino severity, but they have not been able to quantify the extent.

When combined with AGW and Climate Change, the net result is record temperatures and heat waves all around the planet. Sound familiar?

Not really, ENSO events produce record temperatures and heat waves all around the planet just fine on their own, and have been doing so
for many centuries.
 
All from your link --->

Multiple studies published in peer-reviewed scientific journals1 show that 97 percent or more of actively publishing climate scientists agree*: Climate-warming trends over the past century are extremely likely due to human activities.
...
And they go on to cite 18 scientific agencies, who agree with the following --->

"Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver." (2009)2

I'd call that Concensus!!!

There you go again, adding in things that are not part of the consensus statement!
The statement is simple and straight forward,
"Climate-warming trends over the past century are extremely likely due to human activities."
and does not mention greenhouse gasses.

Please show us say just 3 papers out of many thousands OR any statement from any of the Academy of Sciences of any of the countries in the World that
(1) AGREE with AGW AND
(2) specifically claim that greenhouse gasses are NOT the MAIN / LARGEST reason for the human-caused warming.

Not only that, I asked for a paper or a National Academy statement which ACCEPTS human-caused global warming but rejects that greenhouse gasses are the main reason. That's what longview was questioning about the consensus and I await for any (3) of the many thousands of peer-reviewed papers or a National Academy statement to support such viewpoint.

@Jack Hays, you are welcome to respond, but only if you understand the question. Your author does NOT accept human-caused global warming and therefore is disqualified from what I asked longview (aside from the reason that Threegoofs pointed out). To answer your follow up question... because it's not one of the peer reviewed papers that consensus studies (under discussion between Media_Truth and longview) were based on.

Your question, indicates that you do not understand where the scientific skepticism originates from.
I agree with the consensus statement, "Climate-warming trends over the past century are extremely likely due to human activities.",
but this in no way agrees that CO2 emissions need be anything we should be concerned about.
Simple CO2 forcing would increase the average temperature by ~1.1 C for each doubling.
Based on that curve, roughly .61 C of the observed warming is from increases in the CO2 level,
and most of this has happened since 1950.
The problem with the catastrophic predictions is they throw in ghost forcing, feedback warming several times greater than simple CO2 forcing,
to arrive at an ECS temperature. This all sounds good until you try to work out the math.
The Hadcrut4 dataset put pre 1950 warming at .28 C.
If the feedbacks were high enough to allow the 1.1 C of CO2 forcing to become 3 C of ECS, it would require a feedback factor of 2.72 times the input, with a latency period.
One of the most vocal alarmist Scientist James Hansen, places ECS latency at 37.5 years for 60% of ECS.
Here in 2019, we have total observed warming of .9 C, of that direct CO2 forcing accounts for .61 C.
The pre 1950 .28 C would have become .28 X 2.72 X .6=.46 C by 1988, and be .46 X 2.72 X .6= .75 C by 2025.
If 2XCO2 ECS were really 3C, then the average temperatures would need to be near 1.31 C by 2019, but they are in fact .4 C lower than that.
We also have not taken into account changes in the other greenhouse gasses.

Thank you for interesting article. I did not realize your man (Shivav) believes that 60% of Global warming is human-made. That's right, not 40% as you stated but 60%!

Nominally, we can account for 40% of the 20th century global warming by the sun alone while 60% should be attributed to anthropogenic activity.

In any case, your article still fails the test since he believes greenhouses are the main component of that anthropogenic activity.

[FONT=&quot][FONT=&quot]This is the contribution to the radiative forcing from different components, as summarized in the IPCC AR5. As you can see, it is claimed that the solar contribution is minute (tiny gray bar). In reality, we can use the oceans to quantify the solar forcing, and see that it was probably larger than the CO2 contribution (large light brown bar). [/FONT][/FONT][FONT=&quot] [/FONT][FONT=&quot][FONT=&quot]Any attempt to explain the 20th century warming should therefore include this large forcing. When doing so, one finds that the sun contributed more than half of the warming, and climate has to be relatively insensitive. How much? Only 1 to 1.5°C per CO2 doubling, as opposed to the IPCC range of 1.5 to 4.5. This implies that without doing anything special, future warming will be around another 1 degree over the 21st century, meeting the Copenhagen and Paris goals.[/FONT][/FONT][FONT=&quot] [/FONT][FONT=&quot][FONT=&quot]The fact that the temperature over the past 20 years has risen significantly less than IPCC models, should raise a red flag that something is wrong with the standard picture.[/FONT][/FONT]

Not what he said in the paper you quoted in last reply. There he was clear that 60% was man-made. and sun was 40%. .... and that's from the most quoted "denier".

The paper was his research result in 2012. His statement in #241 was his further evolved view in 2018. In any case, your challenge was met.

Nope, the challenge was not met since Shivav confirmed that greenhouse gases are the main way in which humans contribute their part to global warming.

Further, the challenge was to find a source that AGREES with AGW and sounds like he does not any longer.

So the challenge failed on both of the 2 conditions.
 
Network with more than 7 000 universities and colleges from six continents have declared a climate emergency and also commited to adress the climate crisis.

Networks of 7,000 universities declare climate emergency

740 jurisdictions and local governments with 136 million citizens have also declared a climate emergency.

I did not question if greenhouse gasses cause warming, I question how sensitivity the climate was to added greenhouse gasses.
The data only supports the low end of the range.

You go on and continue to argue with Media_Truth questioning that greenhouses are not an important part of human-caused global warming. Media_Truth and I (and overwhelming majority of scientists) are telling you that they are THE MOST important part of human-caused global warming.

So, again, show us ANY paper (or 3) that believes in AGW but claims that greenhouse gases are NOT the most important component or any statement to that effect from a National Academy of Sciences from any country.
