ENVIRONMENT: CO2 levels at 800,000 yr high

 
555Views 33Comments Posted 05/08/2018

As temperatures bust heat records across the globe and wildfires rage from California to the Arctic, a new report produced annually by more than 500 scientists worldwide found that last year, the carbon dioxide concentrations in the Earth's atmosphere reached the highest levels "in the modern atmospheric measurement record and in ice core records dating back as far as 800,000 years."

While the most significant jump was the global average for carbon dioxide (CO2)—which, at 405.0 parts per million (ppm), saw a 2.2 ppm increase from the previous year—concentrations of other dominant planet-warming greenhouse gases, methane (CH4) and nitrous oxide (N2O), also hit "record highs," according to State of the Climate in 2017 released Wednesday, Aug 1

Greg Johnson, an oceanographer at the National Oceanic and Atmospheric Administration (NOAA) Pacific Marine Environmental Laboratory in Seattle, warned that even if humanity "stopped the greenhouse gases at their current concentrations today, the atmosphere would still continue to warm for  the next couple decades to maybe a century."

The 332-page report—which was overseen by NOAA and published as a special supplement to the Bulletin of the American Meteorological Society—also notes that 2017 was among the three hottest years ever, taking the top spot for warmest non-El Niño year since scientists began measuring in the 1800s. NOAA data released last weekend shows that 2018 is on track to set a new record.

The report details how "much-warmer-than-average conditions" across much of the world's lands and oceans has meant three years of "unprecedented" coral bleaching, Arctic air temperatures that are "warming at a pace that was twice the rate of the rest of the world," rapidly melting glaciers and ice sheets, and devastating tropical storms—such as Hurricanes Irma and Maria—that reflect "the very active state of the Atlantic basin."

In its regional analyses, the report notes that "the United States was impacted by 16 weather and climate events that each caused over $1 billion (U.S. dollars) in damages. Since records began in 1980, 2017 is tied with 2011 for the greatest number of billion-dollar disasters. Included in this total are the western U.S. wildfire season and Hurricanes Harvey, Maria, and Irma. Tornado activity in the United States in 2017 was above average for the first time since 2011, with 1,400 confirmed tornadoes."

Do you know any terms besides "rude and meaningless remark", "bullying", "name calling", "questioning ability to engage in critical thinking", "anger issues" https://media1.tenor.com/images/40647bdf9cf02b78836ad6d166bf339b/tenor.gif?itemid=5355082

Do you know any terms besides "take it on the chin" "trigger warning" or "cut the crap"???? and name calling? "Stoic individual" "tough cookies" , what are we all suppose to be prize fighters? What is your problem that you cannot enter into a intelligent verbal discourse? Your words speak for themselves. And they have said more than enough.

Ah! And here I thought commentators on this site were stoic individuals ... tough cookies who can take it on the chin. Next time I am about to express my personal conviction or belief (whether it conforms to established norms of the snowflake generation or not, or even if is flawed by someone's standards), if it is at all controversial, I'll try to give you a "trigger warning" ... </s>

Your comments on vaccines clearly shows you do not believe valid, well researched information. That makes you a member of the Flat Earth Society. I can also not help to notice anger issues in your directive “ to cut the crap out”, a rude and meaningless remark. I am playing fair, I am clearly and specifically identifying your comments as inaccurate based on factual research. Your inability to recognize that and resort to “ bullying” type behavior such as name calling and using terms such as “ cut the crap out” are clearly indicative of a questioning ability to engage in critical thinking. Therefore, I see no point in furthering this conversation.

--A member of the Flat Earth Society is not a racist remark. --. If you read carefully, I didn't say it was racist. It's all about labelling someone when there is little to no way to dispute the label; thereby intentionally shutting them down. Sort of like "when did you stop beating your wife?" Neither am I a Flat Earther anymore than I'm a racist. So cut the crap and at least try to play fair!

Yes, Banjaxed, there lies the nub. One group of scientists dispute the findings of another and on and on it goes. What it comes down to is which theory(ies) I agree with and you, likewise. I just have a problem with CO2 being the culprit for 3 reasons:. 1) CO2 is essential for Man and plants; 2) it can (and is) taxed --follow the money conspiracy! And 3) I believe the concentration of CO2 is and has always been too small in comparison with other factors to make an appreciable difference in MMGW theory despite the "concensus" BS. The alternate factors: sun, clouds, cosmic rays, dying stars, etc. influence and simply make MORE sense to ME. Therefore, despite other scientists' proclamations, that is the theory I'm sticking with. No hard feelings, I hope.

"Not a greenhouse gas at 0.04%". At what percentage does CO2 need to be present at to enable it to absorb infrared radiation?

I have watched the video.I was aware of the cosmic ray hypothesis but had not seen this video before. Here is a list of scientific papers that refute Henrik Svenmark's claims. https://agwobserver.wordpress.com/2009/08/31/papers-on-the-non-significant-role-of-cosmic-rays-in-climate/ I haven't read the papers but I have read the synopses. Also, in this video the points you raise concerning volcanoes and solar are covered. If you jump forward to 42 minutes you will get to the part where cosmic rays are mentioned. https://www.youtube.com/watch?v=RffPSrRpq_g

CO2 is the basis of almost all life forms on Earth, including ourselves. A concentration 5 times present values would be a huge benefit to plants, trees and crops currently gasping for more of their air (carbon dioxide).

CO2 is not a greenhouse gas at 0.04%, excluding water vapor.

A member of the Flat Earth Society is not a racist remark. It describes someone, who in spite of extremely well documented data, refuses to believe the conclusion. A lot of that going on today, especially in some of these posts. BTW, as a special education teacher of 43 years I can assure you that disabled children are not a result of vaccines. There is a plethora of research available that debunks that assumption. In addition, we did a great deal of damage to children, from measles outbreaks to the resurface of some childhood diseases that had almost been eradicated when we blindly stopped vaccinating children. If you wish to give up your membership in the Flat Earth Society you will need to embrace realistic, intelligent research and stop with the name calling just because you disagree with someone's politics. In case you are unaware, thats bullying.

Being a flat earther is not a racist comment although just about mentioning any opposing view these days is dangerous as it leads to that type of response. There is indeed a large thriving community of flat earthers As to vaccines and dangers thereof i have never heard such a luddite remark. Of all the modern miracles of medical science vaccination has to be number one . you probably are not of the generation that suffered Polio . it is starting a come back unfortunately as people forget to vaccinate against it. Might i stress yet again that i am not from the US and have no idea what you imply by linking me to comments about Liberals etc. I am panamanian and would appreciate being treated as such. Though originally of european descent .

Occurs to me that this and other climate change options are dismissed because you can't TAX them and grant money for CO2 researchers is negated.

Banjaxed, this is an interesting video but only draws the conclusion that CO2 is the cause of global warming. -- Think clouds, cosmic rays, volcanic particulate, solar activity, and others. It's worth a watch to the very detailed study on how CLOUDS are a very important factor on earth's climate -- if you don't watch anything, watch Svensmark: The Cloud Mystery https://www.youtube.com/watch?v=ANMTPF1blpQ

Labelling someone a "flat-earth[er] is so beneath you to counter an opposing point of view. (Akin to Racist, or any of the other "-ists" in common use). Thought you were better than that! And vaccines are actually dangerous because they employ Mercury as a preservative. And Mercury, as you must conclude, Is a toxin to the body. How might you, oh level-headed one, explain the epidemic of children with ADHD and other new and wonderful mental and physical disorders? Maybe it's Liberalism (a newly-coined--but accurate--pejorative). Let me correct that as I no longer think this about Liberalism--"Left-Wing" thinking is the more accurate villain. So which are you? Trump Derangement Syndrome --do you suffer from it?

Yes my bad!. Another not so small, but never discussed issue is the vast amounts of oil and coal available on this planet. Without getting into a theological discussion let's just call him or her a higher power. Do you suppose that so much oil would have been placed on this planet if it was not meant to be used. That would have been poor planning on the part of the "Higher Power". Unless you believe that we were placed here in order to provide entertainment as a Higher Power watches us destroy ourselves. In due time, before the oil runs out we will develop a better and more efficient way to provide the energy we need but it certainly won't be using solar panels or wind energy. As to who profits greatly with these chicken little stories look to these two industries. As I said follow the money. The only constant source and never changing force are the tidal currents and I predict that some day, someone will find a way to utilize this poorly used source.

Data can be skewed (remember the "hockey stick" theory). Computer models:-garbage-in-garbage-out. You can submit all the YouTubes to attempt to prove one point and I could submit an equal number to counter. I DON'T think MAN is that powerful but I do believe God, or Mother Nature or whatever ultimate being is far superior to Man and will do what it wants and clean up our little messes like a parent does for a child. Man has only been on this planet for a few thousand years and will come and go but the Earth is and always has been the potent force. When the Earth overpopulates--a plague occurs or a natural disasters to keep things in equilibrium. What? you say?--Man has the power to create or stop these? I don't think so. I'm not recommending Man has the right (although has the ability) to abuse our planet but I don't think merely living a normal life should be taxed for redistribution or to fill elite pickets. I critically think on Man's assertions and you may be interested to know that the [false] claim of "preponderance of scientists conclude" regarding Man-made Global Warming is a joke and another big LIE.

I hope during his next term President Trump will cut all grants to these professorial nut cases and you will soon discover that the "chicken little" proclamations will disappear. I suppose the U.N. will continue but hopefully the U.S. will quit supporting that useless organizations as well and that should take care of it.

was ever thus..flat earth society is still pretty active. No amount of scienevidence will convince them, so stop bothering. Vaccines had the same pushback from naysayers. Personally I go with the scientific (500 in this case) community on this one and vote for doing whatever necessary to try and control humanity”s indifference to the problem. It’s because of the attitude of some of these posters that its possibly too late ..very sad for the next generations. I dont see why its all down to money though . Most of these scientists working on the issue are cycling to university every day and are not on overseas jollies and to date very little tax has been raised from the public. I see that as a faux argument and one intended to absolve those who cant see the woods for the fires . EditReply

Here is the bottom line. If we quit messing with Mother Nature by allowing small fires to clear the underbrush, stop diverting the flow of water into the ocean to save a few fish etc., nature and the natural changing environment will take care of itself. The major problems always occur when we think we are smarter than evolution. Smart people will adjust to the changing environment and act accordingly instead of trying futilely to impact what can't be fixed. Environmentalists are the bane of the universe IMHO. Having said that I was pleased to see them ban plastic straws in California. That will allow the people of China to increase their use without impacting the environment. LOL Can you not see the idiocy of all this environmental gerrymandering?

"The forest fires alone this year have contributed more to the pollution of the atmosphere than human beings could ever hope to do." There is a flaw in this statement. You're an intelligent person, I'll let you work it out for yourself.

Complete BS. It is called “weather” and it happens. Kalipornia, other states and the thugs at EPA/USFWS fenced off millions upon millions of acres of land so no human except enviro-Nazies could go there for decades. With this new fire suppression and horrible forest management policies, the fuel loads built up unnaturally instead of being more regularly burned away by naturally occurring fires. When fires finaly did strike, it was devastation, killing the forest with intense heat and polluting the entire world. How convenient to blame the fires on the climate hoax so that heavier and new taxes, fees and oppression can be can passed. The article provides no data, uses speculation, supposition and fear mongering to scare the populace into forking over more money to the greedy and subversive perpetrators of the global cooling/warming/climate change fraud.

Simply follow the money. The goal is to eventually tax (carbon tax or similar) everyone, to fill the coffers of the people who know what is good for us. The forest fires alone this year have contributed more to the pollution of the atmosphere than human beings could ever hope to do. What these idiots would have us do is go back to living in caves depriving ourselves of the very things we all work so hard to achieve. They on the other hand will continue to benefit with the infusion of cash in their bank accounts with which they can enjoy all of life's perks, including flying around in private jets to the various "climate change" gatherings all over the world. I call BS on this whole fiasco. If naturally occurring "climate change" is causing problems with flooding, etc., I would suggest moving to higher ground because the climate will change regardless of human interference. Time to get your ducks in a row.

You should submit your data to the scientists. I'm sure that when they see it they will say that man's effect on atmospheric CO2 was all a big mistake and that we should all carry on regardless. "Without data you're just another person with an opinion." -W. Edwards Deming. Here's a video that simplifies the facts for you to ignore. https://www.youtube.com/watch?time_continue=337&amp;v=kQ9hPl9dl98

I bet that if humanity accounted for zero emissions of CO2 (which would be impossible, since we need to cook, move about by transport, keep ourselves warm or cool, and when we die, we decompose and give off gasses), "the atmosphere would still continue to warm for the next couple of decades to maybe a century" unless natural forces caused us to enter a cold phase (totally possible). Faux scientists don't want to admit that Earth is going to continue releasing greenhouse gasses by decomposing organic matter, forest fires, volcano eruptions, and others all by itself and Man is powerless to stop it. But they chose to concentrate on mankind's minor contribution since they can't put a carbon tax on Mother Nature's much larger impact and divert attention from a 400 ppm CO2 level when the biggest greenhouse gas is water vapor. So, let's perpetuate the fallacy that the sky falling is because of humans so we are made to feel guilty for living and pay money for a God-given right to existence so those behind the scare tactics can keep getting richer.
