Global warming could suffocate life on Earth as oxygen levels fall, research shows

Falling oxygen levels caused by global warming could be a greater threat to the survival of life on planet Earth than flooding, according to researchers from the University of Leicester published in Bulletin of Mathematical Biology.

A study led by Sergei Petrovskii, Professor in Applied Mathematics from the University of Leicester’s Department of Mathematics, has shown that an increase in the water temperature of the world’s oceans of around six degrees Celsius – which some scientists predict could occur as soon as 2100 – could stop oxygen production by phytoplankton by disrupting the process of photosynthesis.

“Global warming has been a focus of attention of science and politics for about two decades now,” Professor Petrovskii explained. “A lot has been said about its expected disastrous consequences; perhaps the most notorious is the global flooding that may result from melting of Antarctic ice if the warming exceeds a few degrees compared to the pre-industrial level. However, it now appears that this is probably not the biggest danger that the warming can cause to the humanity.”

“About two-thirds of the planet’s total atmospheric oxygen is produced by ocean phytoplankton – and therefore cessation would result in the depletion of atmospheric oxygen on a global scale,” he added. “This would likely result in the mass mortality of animals and humans.”

The team developed a new model of oxygen production in the ocean that takes into account basic interactions in the plankton community, such as oxygen production in photosynthesis, oxygen consumption because of plankton breathing and zooplankton feeding on phytoplankton.

While mainstream research often focuses on the CO2 cycle, as carbon dioxide is the agent mainly responsible for global warming, few researchers have explored the effects of global warming on oxygen production.

The 2015 United Nations Climate Change Conference is currently being held in Le Bourget, Paris, from November 30 to December 11, and yesterday saw the largest gathering of world leaders in history.

It will be the 21st yearly session of the Conference of the Parties to the 1992 United Nations Framework Convention on Climate Change (UNFCCC) and the 11th session of the Meeting of the Parties to the 1997 Kyoto Protocol.

The conference objective is to achieve a legally binding and universal agreement on climate, from all the nations of the world.

    This is just great!

    Oxygen levels have been dropping WITHOUT our intervention:

    This will only accelerate our demise.

  2. Fred says:

    The only thing dropping our Oxygen levels are stupid scientists talking rubbish about global warming just trying to keep the gravy train going.

    • Stew says:

      You personally have no contact with any scientists I bet, but, have the audacity to think you know what they do.

    • ksea says:

      Yes, thousands of scientists conspired to fool teabillies, and frustrate the fossil fuel industry.
      You strain out a gnat but swallow a camel.
      Or maybe you’re just a dumb troll paid by some despicable corporate scumbags.
      Or your ignorance is your guide and you just can’t make progress.
      Or you’re in 3rd grade.

  3. Mark says:

    Deforestation is also part of the declining oxygen problem.

    Burning fossil fuels also reduces oxygen.

    We have passed the limits to growth on a round, finite planet.

  4. Hosea McAdoo says:

    Global warming is the greatest threat to animal life ever. Six degrees of warming will likely fall into the
    lifespan of your grandchildren. If nothing is done by the fools we have as leaders you probably will
    not have great grandchildren! Only plant life will remain.

    The good news is that in a few million years when the new oxygen concentrates there will likely be a new animal line to use the niche the oxygen provides. Whatever it is it will not be human as animals began as very simple organisms and it took countless millions of years for humans to arise.

    One of the commenters said, “The only thing dropping our Oxygen levels are stupid scientists talking rubbish about global warming just trying to keep the gravy train going.” What stupidity! He knows nothing of science and especially scientists. Getting two scientists to agree is rare and they are not afraid to disagree. To expect tens of thousands of scientists to hold a conspiracy is as likely as winning the lottery a thousand times in a row. The idea that science is a “gravy train” just reaffirms the complete ignorance. Maybe he will write about the flat Earth, creation, Geocentricity and why fools speak loudest.

    Global ‘warming’ is a hoax to cover what is really happening. Massive global GEOENGINEERING is occurring. Every day, all day, 24/7 jet tankers are spraying nanobits of metallic substances in the stratosphere. Sometimes much lower right into the storm clouds. This is a corporate/ military enterprise to enable the military to communicate (by using this giant plasma ‘shield’) and subjugate (by complete control of the earth’s weather. Also, by the corporate interests (need I mention names?)to dominate food and water supplies, and to heighten the profits of the pharmaceutical industry. Huge electromagnetic pulse devices and weapons are able to do all of this with extreme precision. (Note the ‘war games’ of the US Navy in the Olympic Peninsula, WA and off the entire US west coast – they are quite blatant about what they’re doing.) All of this is no secret. To see what is happening all you have to do is LOOK UP. There is an excellent book which explains everything in detail: CHEMTRAILS, HAARP AND THE FULL SPECTRUM DOMINANCE OF PLANET EARTH by Elana Freeland. I highly recommend it. You’ll come away incredibly frightened by the insanity of our ‘rulers’. Complete and total insanity. They are killing us and they are killing the entire earth…. for dominance, and profit.
