Trevor Noah on non-scientists denying global warming & the idiots who mislead or believe them.

Proof Hillary ISN'T

If I ever get tried for murder I hope you are not on the jury, Malbur. Your threshold for what constitutes evidence is not exactly rigorous.

My last comment was said without my permission, just ignore it.

X - please see the LAST graph I posted which includes land, air, & water.

X - No, I am saying the last graph is the most inclusive.
Your objection was the other graphs only showed land data.
So, the last graph shows ALL the data together; land, sea, and air,
and it still shows that global warming is rising.

Any more excuses ?

V - As I am sure you are aware, when dealing with mathematics, one often deals with levels of certainty, rather than absolutes. This does not prevent conclusions, but further testing may be warranted. When looking at the big picture, we can clearly see with very high levels of confidence, that something is largely amiss with the CO2 levels, which is not only reflected in the numbers themselves, but in odd weather patterns not previously experienced. Yes, it is a complex system. But, that does not mean that it can't be understood and great progress has been made in this area of study. Doing nothing about it, does not result in solutions and solutions are needed. Thus, we should at least try those things most likely to at least slow the rate of increase and adjust responses based on results.



This ‘big picture’ view does not give any insight into years or decades. What it can do is give a better perspective. Much of the current evidence, and arguments of the doubters, rests on data from a few years, which can be confusing. This rather clear parallel movement of temperature, CO2 and sea level provides a powerful story. Over a long period of time, THEY MOVE IN UNISON, just what one would expect with CO2 being a heat-trapping greenhouse gas, and warmer temperature melting the ice sheets, raising sea level.

The graph shows 4 major ice ages, on a cycle of roughly 100,000 years. The last ice age peak was just over 20,000 years ago. At that time sea level was almost 400 feet (120 m) below the present due to the huge quantity of water locked up in the ice sheets, more than a mile deep over North America and Europe.

The other very interesting sea level event was approximately 120,000 years ago, during the previous “interglacial” — the warm period between ice ages. We are presently in an interglacial. In that last interglacial (known as the Eemian to geologists) the temperature was a few degrees warmer than at present. Research over the last few years indicates that sea level rose about 26 feet (8 m) higher than present, possibly even a little higher.

Over the last century we have warmed almost two degrees F and are headed to much greater increases over the course of this century. Warmer temperatures are associated with higher CO2 levels. Warmer temperatures mean increased melting of the polar ice sheets and raising sea level. This presents a major concern due to the catastrophe that several feet of higher sea level would cause to coastal cities and infrastructure globally. Because our warming is now happening a lot faster than previous periods of natural abrupt climate change, there is no way to accurately predict how many years it will take for enough ice to melt to raise the ocean that much.

The real big issue of concern is the level of CO2. As shown on the green line in the middle, it has fluctuated between about 180 – 280 ppm (parts per million) over the last 400,000 years. Now the level has shot up like a rocket to 393 ppm, a 40% increase. (Note the line goes way up into the area of the red graph.) This correlates with our emissions from burning fossil fuels, reduction of forest cover, and other factors. The concern is the way that average global temperature moves in concert with CO2.

If temperatures later this century continue to climb, causing all the ice sheets to eventually melt, there will be catastrophe — even if it takes many centuries for that to fully happen. The last time that CO2 levels were in the range near a 1,000 ppm, was about 55 million years ago. At that time there were no polar ice sheets and sea level was approximately 250 feet (75 m) higher than today.

While sea level and climate have changed in the past, it was LONG before our human civilization.http://www.johnenglander.net/sea-level-rise-blog/420000-years-temp-co2-and-sea-level-what-coincidence/

V - the pouring of man-made chemicals into the environment is certainly not a good thing. I agree with you on that. And Trump recently rolled back laws restricting air pollutants, which does not help.

I am less concerned with people moving between borders. That mostly does not affect world population levels.
Instead, I am more concerned with how many children they have wherever they are.

I never suggested that people totally stop "breeding", nor completely stop burning carbon.
But, a significant decrease would be helpful.

Well, have a safe & fun winter this year.

No one said science was easy. But, that doesn't justify just blowing off their findings.
Their findings are not based on one sample, but many samples.
Ignoring data, because you don't understand it, is foolish.
As foolish as ignoring the test results from your doctor, because you don't understand it.
You are neither a MD, nor a PhD. So, try to learn what the tests mean and value their efforts
and findings, as you likely couldn't do it.

Kudos to Kaylana for schooling Jersey Jim.

Quote: “The more people = the more pollution + the more global warming due to more burning of fossil fuels.”

I’m sorry, but I thought more people = man + woman.

Aha ! So, the error is in a "belief" system interfering with acceptance of test results.

"what am I excusing?"

Making no effort to find solutions and making excuses to do nothing productive about it.
This misleads others to consider the same.

It is clear that carbon dioxide levels parallel global temperatures
and the polar ice is melting which results from that ice melting.
While you think that has multiple causes, do you really think
that the burning of fossil fuels does not contribute to that ?
See the graphs above.

Well, for one thing, you "believe" there is no problem, while the scientists who actually do the research and have a much better understanding of the data than you, see one.

Wow ! You'll go to extremes to invent excuses. Have you considered that a lot of that ice that is melting is ABOVE SEA LEVEL ?

Look. It's obvious, that you want to BELIEVE that mankind has nothing to do with the rise in atmospheric carbon dioxide levels and nothing that I post has the possibility of waking you up to reality.
So, you will be one of the many people to blame for taking no preventive actions, except it seems
that you are at least somewhat against pollution in general. Hopefully, you will at least promote action against pollution.

I've already wasted too much of my precious time on you.

This reminds me of the relatively ancient belief promoted by companies that pollute.
Their wrong answer for pollution was a slogan - "The answer to pollution is dilution."
No. The answer is stop polluting.

mic - thanks for adding some substance.
Yes, that does clarify for those who didn't understand.

LL - Pollution is definitely a problem. I am guessing most people realize that, even the polluters.
It's just that their greed is more important to them.
But, what some don't realize, is that there are many types of pollution,
and just because you can't see, or smell it, doesn't mean you can't test for it. It can be tested.
This certainly doesn't mean, that it doesn't exist.
Carbon dioxide is a normal part of the air we breathe......at normal levels.
Above those levels, there are harmful environmental affects including global warming.

Thanks for your comment. You are spot on about the pollution.
Hopefully, people will become a lot smarter about this situation.
Unfortunately, if the global warming is not reversed, the impending mass extinction will be a lot more devastating to humans and many other species, than simply a dog shaking off fleas.

Soo
you all think your right about Co2 global warming and climate change.
Well get educated by professionals

Interesting movie. However, the data from the last 800,000 years sure seem to indicate that atmospheric carbon dioxide levels and surface global temperature are tightly linked to me;



The film focused not on global surface temperature, but on upper atmospheric temperature.
