Indicators of a Warming World

Recommended Posts

Due to the rise over about the last century and a half in atmospheric levels of various powerful greenhouse gases, the Earth is abruptly and rapidly warming, which is causing accelerating climate changes and disruptions. One of these greehouse gases is carbon dioxide, which has risen from the pre-industrial level of about 280ppm to the current 415ppm (and still rising rapidly). The last time CO2 levels were this high was about three million years ago.....that was before the human species had first evolved into our current form, so there were no humans on Earth then.

How Does Climate Change Impact Life On Earth?

Most species on Earth, including humans, are accustomed to the climate as it has been since the last glacial period ended over 10,000 years ago. However, anthropogenic GHG emissions are setting the stage for rapid and severe changes to the climate, faster than we can easily adapt to. These changes can lead to increased deaths and damages from a variety of causes, such as extreme weather events, lower crop yields, increased geographic and temporal reach of vector-carried diseases, infrastructure damage, and the escalation of a conflict that arises from these increased insecurities that the world’s population shall face.

The Last Time CO2 Was This High, Humans Didn’t Exist

(excerpts)

The last time there was this much carbon dioxide (CO2) in the Earth's atmosphere, modern humans didn't exist. Megatoothed sharks prowled the oceans, the world's seas were up to 100 feet higher than they are today, and the global average surface temperature was up to 11°F warmer than it is now.

 

Carbon dioxide is the most important long-lived global warming gas, and once it is emitted by burning fossil fuels such as coal and oil, a single CO2 molecule can remain in the atmosphere for hundreds of years. Global CO2 emissions reached a record high of [37.1 billion tonnes in 2018, up 1.7 percent from 2017(updated)]. Carbon dioxide and other greenhouse gases warm the planet by absorbing the sun’s energy and preventing heat from escaping back into space.

 

The news that CO2 is near [415 ppm] for the first time highlights a question that scientists have been investigating using a variety of methods: when was the last time that CO2 levels were this high, and what was the climate like back then?

 

There is no single, agreed-upon answer to those questions as studies show a wide date range from between 800,000 to 15 million years ago. The most direct evidence comes from tiny bubbles of ancient air trapped in the vast ice sheets of Antarctica.

 

For a 2009 study, published in the journal Science, scientists analyzed shells in deep sea sediments to estimate past CO2 levels, and found that CO2 levels have not been as high as they are now for at least the past 10 to 15 million years, during the Miocene epoch.

 

This was a time when global temperatures were substantially warmer than today, and there was very little ice around anywhere on the planet. And so sea level was considerably higher — around 100 feet higher — than it is today,” said Pennsylvania State University climate scientist Michael Mann, in an email conversation. “It is for this reason that some climate scientists, like James Hansen, have argued that even current-day CO2 levels are too high. There is the possibility that we’ve already breached the threshold of truly dangerous human influence on our climate and planet.

 

Sea levels are increasing today in response to the warming climate, as ice sheets melt and seas expand due to rising temperatures. Scientists are projecting up to 3 feet or more of global sea level rise by 2100, which would put some coastal cities in peril.

 

While there have been past periods in Earth's history when temperatures were warmer than they are now, the rate of change that is currently taking place is faster than most of the climate shifts that have occurred in the past, and therefore it will likely be more difficult to adapt to. 

 

A 2011 study in the journal Paleoceanography found that atmospheric CO2 levels may have been comparable to today’s as recently as sometime between 2 and 4.6 million years ago, during the Pliocene epoch, which saw the arrival of Homo habilis, a possible ancestor of modern homo sapiens, and when herds of giant, elephant-like Mastadons roamed North America. Modern human civilization didn’t arrive on the scene until the Holocene Epoch, which began 12,000 years ago.

 

Regardless of which estimate is correct, it is clear that CO2 levels are now higher than they have ever been in mankind’s history. With global CO2 emissions continuing on an upward trajectory that is likely to put CO2 concentrations above 450 ppm or higher, it is extremely unlikely that the steadily rising shape of the Keeling Curve is going to change anytime soon.

The only thing I'm interested in hearing from you CCf is the reason you dropped your old screen name, pogorocks, and came back as a sock puppet?  

 

And where you posted during the time you were gone from the forum and under what screen name?

 

Beyond that, nothing you post or claim has any interest or validity.

 

Just saying ...

The earth became really really cool....

 

and then...warmer and warmer

 

There is the story of FIVE ICE AGES.......children

" You will never see snow again"

 

Try to find a link to that exact quote, why don't you, Zooshyt. LOLOLOLOL. You're getting confused about the details of your denier cult myths.

 

And.....so what if one climate scientist, who was referring only to Great Britain and talking about people's future children never seeing snow, got a bit too hyperbolic in one statement. The very well explained and very detailed summaries of the scientific consensus on human caused global warming and its consequences, that have been published by a number of scientific and governmental agencies, DO NOT claim that global warming will cause there to be no more snow anywhere, you silly denier cult troll.

As I have said before on another thread about the silly fool, BeALoser, who posts so much off-topic garbage and psychotic nonsense......

 

Of all of the deranged rightwingnut retards on this forum, the denier cult troll, BeALoser, is one of the most severely afflicted victims of the Dunning-Kruger Effect to repeatedly embarrass himself in front of all the people who know far more than he does.

 

I have always debunked his denier cult lies and fraudulent claims with the scientific facts from reputable sources. Unfortunately he is too ignorant, stupid and full of deliberate misinformation pumped into his tiny little brain by the propaganda pushers working for the fossil fuel industry to accept reality. And, of course, the Dunning-Kruger Effect just fools him into imagining that he is smarter and knows more about climate science (and everything else) than the tens of thousands of PhD climate scientists who almosts unanimously affirm the grim reality of human caused global warming and its consequent increasingly disastrous climate changes. He loves to post pseudo-science twaddle cooked up by the fossil fuel industry and, even though it also gets debunked by the real science, he idiotically imagines that he has triumphantly defended his denier cult anti-science insanity. He is a troll......one well worth ignoring as an irrelevant and meanigless distraction.

There was no QUESTION that FACST would make Chooser the brainwashed MORON Cry or lie or spew some kind of STUPIDITY but what he would NEVER do is ADDRESS the FACTS. He knows just as we do he is FAR too STUPID to even try. He never does.  GOD Chooser is stupid

Do you delude yourself that EVERYONE who makes a fool out of you is a new nick for someone else who slapped the stupid out of you before?  GOD you are stupid and what was OBVIOUS was that you were NEVER going to try to address the FACTS since you are FAR too STUPID to ever do that. You do KNOW how stupid you are RIGHT?

I dont even have to read your STUPID post to KNOW you STILL didnt even TRY to address the FACTS cited above.  Even though you are being RIDICULED for being too STUPID to even try you STILL keep making a fool out of yourself by not even TRYING and even YOU know like we ALL know you are just flat out too STUPID to even  TRY to address FACTS.
