Many people, particularly a large segment of the American population (especially the voting population) continue to believe that this is all a hoax, despite the overwhelming evidence (to the point of absurdity) to suggest that this is, indeed, a real threat. Of course, we all know the general lack of credibility that science is given in the United States, at least in the political climate. Like with so many other things, the United States has continued to lag behind badly, to the point that it has become a source of embarrassment for many American environmentalists and concerned citizens. Even, perhaps, to the average citizen that recognizes the real dangers of global warming, and see the clear pattern of ever increasing extremities in the weather, with record droughts and floods, sometimes even in the same area within a relatively short period of time (such as in the Midwest in recent years). We have seen the hottest years on record with increasing regularity, and have had to endure megastorms, which were once considered "once in a lifetime" storms, such as Katrina and Sandy.
Like with another disaster that was not natural (September 11th), there is the sense among most that what we have seen is really just the beginning. That we will not only continue to see such events, but that they will increase in both frequency and severity.
It is enough to make even the bravest among us begin to truly despair for the future of life on this planet.
All the signs are there that this is no fluke, or huge conspiracy, but something far worse, and far too real. It has reached the point where the signs are so obvious, that you have to be willfully ignorant to continue to ignore it.
Yet, nowhere are people ignoring it en masse as much as Americans are ignoring it.
Here is one example that seemed exceedingly obvious to me, yet somehow, it never seems like a story that anybody else remembers. It is mentioned in this article that China passed the United States as the greatest overall polluter (in recent years)
When China first "earned" this title, Americans suddenly awoke to just how damning and damaging such pollution really was, much like many so-called conservatives only woke up to the excesses of the Bush regime once Obama was in the White House, and they promptly and conveniently blamed the man then in office, rather than the one who had created so much of it during his long, eight-year tenure in the same office.
There were those American Olympic athletes who went to the Beijing Olympic games in 2008, arriving at the airport with gas masks, as a form of protest (apparently). Where the hell were they when their own President was essentially dismantling important environmental legislation and allowing corporations to have their way in poisoning our land, our water, our air (hell, even our food!)? Where was this well-placed outrage when the very man who represented their nation, who had promised to be the "environmental president" when he was a candidate, only to reverse this a mere two months into office and suggesting this reversal was based on new scientific evidence (the first, and perhaps even the worst, in a long line of slaps in the face to our collective intelligence by any administration, if ever it could truly be limited to just one) was denying that carbon emissions weren't actually doing the damage that it had long been believed they did. Not fully two months into office, and he reneged on an important campaign promise, yet Americans (particularly those calling themselves conservatives and supportive of the President). Where were these Olympic athletes then? Why do Americans only seem to recognize the faults with other countries and peoples, and never seem to do anything about their own problems and glaringly obvious imperfections?
I think Justin Gillis summed it up aptly in this article:
"China is now the largest emitter, but Americans have been consuming fossil fuels extensively for far longer, and experts say the United States is more responsible than any other nation for the high level."
It should be added, also, that China has four times the population that the United States has, which means that Americans still hold the as yet uncontested, and dubious, position as the greedy consumers of fossil fuels in the world, and no one else really comes close. That is not to undermine the extent of the damage that China's pollution has. It is only to point out the overly convenient hypocrisy that Americans often take on this (and other) issues. They direct a very public spotlight on, and criticize, the Chinese for the "sudden" problem of carbon emissions, or point the finger of blame on those who are burning the rainforest in South America (among other places), while ignoring not only the deeper issues of poverty and injustice in those places, but also (again too conveniently) ignore the deforestation that went far too long uncontested (some might suggest unnoticed) right here in the United States for many decades.
The Brazilian government is trying to crack down on deforestation. I will admit that I am not overly familiar right now with what the Chinese are doing (assuming they are doing anything) to counter the rise of carbon emissions in that country.
But I know what the American government, and more importantly the American people that the government is elected by and represent have traditionally done in recent decades to counter massive pollution, deforestation, and particularly carbon emissions right here at home: virtually nothing.
In the eighties and into the early nineties, I remember being considered an "environmental wacko" for daring to care about the Earth, and believing in the "global warming theory". Most people, even most Americans, are no longer laughing. But at the same token, the American government rarely actually seem to do anything about it. George H. W. Bush took a hardline position against further regulations designed to protect the environment, setting himself, and the nation that he represented and led, at odds with most of the rest of the world. Here is a link to a New York Times article about that conference:
http://www.nytimes.com/1992/06/11/world/earth-summitbush-rio-president-has-uncomfortable-new-role-taking-hard-line-earth.html
Then, a few years later, the United States (once again) was at odds with the rest of the world in not fully ratifying the Kyoto Protocol. It was an under-reported story here in the United States at the time (predictably), but I think this was no less than the true beginning of when the rest of the world began to acknowledge that there was just a political disconnect between most of the rest of the world and the United States, which seems too often to view itself as exempt from everything that the rest of the world has to deal with. The rest of the world did not wait for America to get on board. They went ahead and signed the Kyoto Protocol, and tried their best to make it work. When the United States (and Australia) petitioned with their objections in 2000, they were overruled. What tentative agreement the United States had given at the time under Clinton for the Kyoto Protocol was withdrawn very quickly once George W. Bush, the self-proclaimed "environmental president" took office. If you would like a fuller history, with much more details, on the Kyoto Protocols, here is the Wikipedia link:
http://en.wikipedia.org/wiki/Kyoto_Protocol
Just in case you maybe do not remember recent history with George W. Bush's environmental promises being forgotten so quickly into his presidency, here's a little quote from the National Resources Defense Council's web page on the subject that should serve as a strong reminder:
"On March 13, 2001, President Bush backed away from his campaign pledge to seek cuts in emissions of carbon dioxide -- the main cause of global warming -- as part of a strategy to regulate together, rather than separately, four air pollutants emitted by power plants. In a letter to Sen. Chuck Hagel (R-Neb.) explaining his reversal, the president cited a recent Department of Energy report that concluded it would be too costly to regulate CO2; he also claimed that CO2 is not considered a pollutant under the Clean Air Act. Below, David Hawkins, director of NRDC's air and energy program, and Dan Lashof, director of our global warming project, let the air out of these arguments."
http://www.nrdc.org/globalWarming/abushco2.asp
My main question then, given this dubious and self-serving history of ours, is how are we going to respond? By denying the bad news, which we have clearly done in the past? By claiming that any further environmental regulations are strangling businesses and detrimental to the economy? Perhaps we will point the finger of blame on some other country that, we believe, is doing worse than us?
Are we ever going to take responsibility for our own actions?
Part of the reason the American car industry was falling behind those of other countries, and failing so badly, was because of this very reluctance to change. While other countries began to focus on more fuel efficient vehicles, Americans continued not only to produce and market, but to purchase huge, gas-guzzling vehicles, which was tantamount to a middle finger in the face of the rest of the world. But the rest of the world was not buying American cars anymore, and increasingly, many Americans weren't, either. Sure, there was (and is) a loyal base. But that base was not enough to keep these companies from nearing bankruptcy, and I suspect that their inflexibility with trying to make their vehicles competitive with those of other nations in terms of fuel efficiency was a much larger part of the reason than was let on in the news.
The indifference on the part of far too many Americans was all too clear. When gas prices rose dramatically in the early 2000's, large gas guzzlers were not seen as often. But as soon as the prices fell again, even just a bit, those same gas guzzlers once again populated the roadways, and sales increased during these periods as well. Talk about stubborn stupidity. This was not even good for their wallets, yet far too many Americans were more interested in what they perceived as a status symbol to economic (let alone environmental) common sense.
After such a history, perhaps some environmental advocates (of whom I consider myself a part of) might be excused for being pessimistic about just what the American response will be to this, and other, pieces of bad environmental news.
Still, we have to keep trying to fight the good fight, right? This is far too important an issue to simply give up on. A part of the task (although by no means the only thing) that needs to be done is communicating, and that is what I am trying to do here.
Read this article by Justin Gillis, published just two days ago in the New York Times. Those conspiracy theorists will continue to ignore the strong evidence, so that they can maintain their cocoon of their own faith, which relies on denial of obvious fact at this point (perhaps particularly on this issue). There are too many people in this world, and this brings with it too many problems.
Heat-Trapping Gas Passes Milestone, Raising Fears
By JUSTIN GILLIS Published: May 10, 2013
The level of the most important heat-trapping gas in the atmosphere, carbon dioxide, has passed a long-feared milestone, scientists reported Friday, reaching a concentration not seen on the earth for millions of years.
Scientific instruments showed that the gas had reached an average daily level above 400 parts per million — just an odometer moment in one sense, but also a sobering reminder that decades of efforts to bring human-produced emissions under control are faltering.
The best available evidence suggests the amount of the gas in the air has not been this high for at least three million years, before humans evolved, and scientists believe the rise portends large changes in the climate and the level of the sea.
“It symbolizes that so far we have failed miserably in tackling this problem,” said Pieter P. Tans, who runs the monitoring program at the National Oceanic and Atmospheric Administration that reported the new reading.
Ralph Keeling, who runs another monitoring program at the Scripps Institution of Oceanography in San Diego, said a continuing rise could be catastrophic. “It means we are quickly losing the possibility of keeping the climate below what people thought were possibly tolerable thresholds,” he said.
Virtually every automobile ride, every plane trip and, in most places, every flip of a light switch adds carbon dioxide to the air, and relatively little money is being spent to find and deploy alternative technologies.
China is now the largest emitter, but Americans have been consuming fossil fuels extensively for far longer, and experts say the United States is more responsible than any other nation for the high level.
The new measurement came from analyzers atop Mauna Loa, the volcano on the big island of Hawaii that has long been ground zero for monitoring the worldwide trend on carbon dioxide, or CO2. Devices there sample clean, crisp air that has blown thousands of miles across the Pacific Ocean, producing a record of rising carbon dioxide levels that has been closely tracked for half a century.
Carbon dioxide above 400 parts per million was first seen in the Arctic last year, and had also spiked above that level in hourly readings at Mauna Loa.
But the average reading for an entire day surpassed that level at Mauna Loa for the first time in the 24 hours that ended at 8 p.m. Eastern Daylight Time on Thursday. The two monitoring programs use slightly different protocols; NOAA reported an average for the period of 400.03 parts per million, while Scripps reported 400.08.
Carbon dioxide rises and falls on a seasonal cycle, and the level will dip below 400 this summer as leaf growth in the Northern Hemisphere pulls about 10 billion tons of carbon out of the air. But experts say that will be a brief reprieve — the moment is approaching when no measurement of the ambient air anywhere on earth, in any season, will produce a reading below 400.
“It feels like the inevitable march toward disaster,” said Maureen E. Raymo, a scientist at the Lamont-Doherty Earth Observatory, a unit of Columbia University.
From studying air bubbles trapped in Antarctic ice, scientists know that going back 800,000 years, the carbon dioxide level oscillated in a tight band, from about 180 parts per million in the depths of ice ages to about 280 during the warm periods between. The evidence shows that global temperatures and CO2 levels are tightly linked.
For the entire period of human civilization, roughly 8,000 years, the carbon dioxide level was relatively stable near that upper bound. But the burning of fossil fuels has caused a 41 percent increase in the heat-trapping gas since the Industrial Revolution, a mere geological instant, and scientists say the climate is beginning to react, though they expect far larger changes in the future.
Indirect measurements suggest that the last time the carbon dioxide level was this high was at least three million years ago, during an epoch called the Pliocene. Geological research shows that the climate then was far warmer than today, the world’s ice caps were smaller, and the sea level might have been as much as 60 or 80 feet higher.
Experts fear that humanity may be precipitating a return to such conditions — except this time, billions of people are in harm’s way.
“It takes a long time to melt ice, but we’re doing it,” Dr. Keeling said. “It’s scary.”
Dr. Keeling’s father, Charles David Keeling, began carbon dioxide measurements on Mauna Loa and at other locations in the late 1950s. The elder Dr. Keeling found a level in the air then of about 315 parts per million — meaning that if a person had filled a million quart jars with air, about 315 quart jars of carbon dioxide would have been mixed in.
His analysis revealed a relentless, long-term increase superimposed on the seasonal cycle, a trend that was dubbed the Keeling Curve.
Countries have adopted an official target to limit the damage from global warming, with 450 parts per million seen as the maximum level compatible with that goal. “Unless things slow down, we’ll probably get there in well under 25 years,” Ralph Keeling said.
Yet many countries, including China and the United States, have refused to adopt binding national targets. Scientists say that unless far greater efforts are made soon, the goal of limiting the warming will become impossible without severe economic disruption.
“If you start turning the Titanic long before you hit the iceberg, you can go clear without even spilling a drink of a passenger on deck,” said Richard B. Alley, a climate scientist at Pennsylvania State University. “If you wait until you’re really close, spilling a lot of drinks is the best you can hope for.”
Climate-change contrarians, who have little scientific credibility but are politically influential in Washington, point out that carbon dioxide represents only a tiny fraction of the air — as of Thursday’s reading, exactly 0.04 percent. “The CO2 levels in the atmosphere are rather undramatic,” a Republican congressman from California, Dana Rohrabacher, said in a Congressional hearing several years ago.
But climate scientists reject that argument, saying it is like claiming that a tiny bit of arsenic or cobra venom cannot have much effect. Research shows that even at such low levels, carbon dioxide is potent at trapping heat near the surface of the earth.
“If you’re looking to stave off climate perturbations that I don’t believe our culture is ready to adapt to, then significant reductions in CO2 emissions have to occur right away,” said Mark Pagani, a Yale geochemist who studies climates of the past. “I feel like the time to do something was yesterday.”
This article has been revised to reflect the following correction:
Correction: May 10, 2013
An earlier version of this article misstated the amount of carbon dioxide in the air as of Thursday’s reading from monitors. It is .04 percent, not .0004 percent.

Find out at http://lowaltitudeclouds.blogspot.com/ what caused the warming that ended over a decade ago. A link is included to a site that presents a simple science-based equation that calculates temperatures since before 1900 with an R2 of 0.9 using only one widely available variable.
ReplyDeleteHopefully, i am misunderstanding your argument. It ended over a decade ago? Sounds like a denial to me. Have you noticed the extreme weather in the last ten years? Tsunamis killing tens of thousands. Hurricanes like Katrina and Sandy. Record drought and then flooding in the US Midwest. Those things did not happen?
ReplyDeleteThose things (except for tsunamis) ARE weather just like you said. You have heard about them because they are in the news which is now world wide. Those who track that stuff observe that similar weather extremes have been experienced for as long as weather has been reported.
ReplyDeleteAverage GLOBAL temperature anomalies are reported on the web by NOAA, GISS, Hadley, RSS, and UAH, all of which are government agencies. The first three all draw from the same data base of surface and near surface measurement data. The last two draw from the data base of satellite measurements. Each agency processes the data slightly differently from the others. Each believes that their way is most accurate. To avoid bias, I average all five. The averages in Celsius degrees are listed here.
2001 0.3473
2002 0.4278
2003 0.4245
2004 0.3641
2005 0.4663
2006 0.3930
2007 0.4030
2008 0.2598
2009 0.4022
2010 0.5261
2011 0.3277
2012 0.3770
A straight line (trend line) fit to these data has no slope. That means that, for over a decade, average global temperature has not changed.
If you look at the links and can understand that stuff you may begin to see why average global temperature stopped increasing and why the current trend is down.
Or you can remain in denial of natural climate change.
Response (Part One)
ReplyDeleteFirst of all, allow me to express my appreciation for the feedback. Although we likely walk different paths on this issue, the main thing I like to see is discussion, and you have provided that. Thank you!
I have not as of yet had the chance to investigate your numbers further. For that matter, I can hardly make any claims to possessing a gifted scientific mind.
That said, take a look around you. Ice caps are melting, glaciers are receding, the world over. Earlier today, I posted the second installment of a couple of blogs about global warming, and this one shows aerial pictures of glaciers and what appears to be drastically altered landscapes that strongly point to climate change. Surely, you have seen imges and read stories about enormous ice caps breaking off in places like Antarctica and Greenland. An overwhelming majority of scientists believe that Global Warming is real. Even George W. Bush, who it can hardly be claimed was a strong believer of global warming, seemed to soften his stance against it in the wake of Katrina, and suggested that there might be something to it (although this was not reflected in his policies).
Now, you ended by suggesting I am denying natural climate change. You also mentioned that I pointe dout all of those things becasue they are in the news. Of course, they are in the news, because they are huge events, and we are trying to figure out what these things mean, and how they might impact us. That these things happened, and continue to happen, is beyond debate. The weather in the last few decades, particularly the last decade, has been more extreme than ever before. More extreme hurricanes and tornadoes and flooding and droughts. These have happened, and seem to be continuing to happen. So, it is up to us to try to understand the ramifications, and diagnose the causes.
Which is where or debate comes in. The other argument about global warming (other than if it actually exists) is whether these changes are "natural", the position you seem to be taking, or whether human activities are impacting, if not outright causing, these things (or at least hastening them).
Response (Part Two)
ReplyDeleteMost of the people that advocate that these changes are occuring naturally do so for political or economic reasons. This argumrnt suggests that we human beings are so insignificant, that we cannot possibly have such an impact on the planet.
Yet, we also know that we, in fact, have had a tremendous impact. Even outside of the possibility of global warming, we see massive oil spills (Prince William Sound in Alaska, or the Gulf Coast, are the two biggest and most obvious examples). We have unbelievable amounts of pollution, so that smog is actually visible in cities like Los Angeles and New York, to name just two. There have been accidents that have made ghost towns of entire regions, like Chernobyl and Fukishima, and that is not even getting into the mass arsenal of weapons that we have built that can literally change life on this planet as we know it forever, and that in an instant, if some mad men so chose. We have killed off, and continue to kill off, huge numbers of species, and destroyed whole natural habitats. We continue to clear forests at a very alarming rate, and this is particularly noticable in the Amazon. Factories belch huge amounts of pollution into the skies, and far too often, illegal dumping poisons our lands and our waters.
Personally, I believe that these activities, far from improving, will only grow worse. More cars, more factories, more filth and pollution, are opening up in the rest of the world, and the human population continues to explode. Malthus's argument, advanced since quite capably by Daniel Quinn, suggests that if human population continues to grow at such an alarming rate, than so will all of these problems. The stress caused as a reaction is simply too much, and too many of us are competing ever more fiercely for fewer and fewer resources. This much I know.
Do I have all the answers? No. Nor do you. Nor does anyone else.
But I am concerned, because thse problems are magnifying evry year. Global warming is challenged by a small but vocal minority of scientists, and perhaps you are among their number.
Maybe that list of detrimental, and undeniable, human activity does not affect you. It seems staggering to me, and more than a litle alarming. Certainly, it would appear as more than enough evidence to most objective people that we should at least begin to seriously do something to change our ways.
Response (Part Three)
ReplyDeleteHere is a question for you: what if you are wrong? If I am wrong, and let us say, theoretically, that human beings actually acted upon these assumptions and at least curbed the excesses, what harm could be done? But if we continue our worst activities, and your arguments prove to be false, what then? That is a tremendous gamble.
Now, I want to to ask you a more direct question here. I already mentioned that the two sides of the argument seem to be divided. Some suggest detrimental human activities need to be curtailed before it is too late, while others suggest that it does not matter what we do, since we have no impact, so let's keep on doing what we are doing. So here is the question I place to you: are you suggesting that we should go on as normal, and not do anything to try to contain carbon dioxide emissions (or other forms of pollution)? Will there ever be a time when maybe we should do something about it?
Or will you remain one of the increasingly few voices (particularly within the scientific community) in denial that we have a problem?
The link in my first post contains this link http://climatechange90.blogspot.com/2013/05/natural-climate-change-has-been.html . In it is a graph that shows average global temperatures since they have been accurately measured world wide. It also shows a simple equation that, using only sunspot numbers and natural ocean oscillations, calculates average global temperatures with 90% accuracy. Including the influence of CO2 had no significant effect.
ReplyDeleteThe temperature measurements show that the warming ended in about 2001. The equation calculates that the trend peaked in 2005.
All that ice is melting because it IS warmer than it was during the depths of the LIA when the water was freezing. The significant observation is that it stopped getting warmer more than a decade ago. The significant discovery is what caused it to get warmer and that it will result in future cooling. The huge thermal capacitance of the oceans will limit the average global cooling to only about 0.15C per decade, and about twice that over land.
The perception that CO2 is a pollutant indicates a lack of knowledge. CO2 is a tasteless, odorless gas that is absolutely necessary for all life on earth. Plants use it to make carbohydrates (and proteins and fats) which are the first link in the food chain.
As to real pollution, we have made great progress in reducing it in the developed world. Prosperity is the best weapon in the fight against pollution. It requires regulations because there is no economic incentive. But too much regulation is just another form of pollution.
We will always have problems . . .and solutions. CO2 isn't, never was, and never will be a problem.
