CO2 Levels Likely To Stay Above 400PPM For The Rest of Our Lives, Study Shows (inhabitat.com) 331

An anonymous reader writes: A new study from the UN's Intergovernmental Panel on Climate Change (IPCC) shows that carbon dioxide (CO2) concentrations in the atmosphere are likely to remain above 400 parts per million (ppm) for many years. Specifically, scientists forecasted that levels would not dip below 400pm in "our lifetimes." The CO2 concentrations of "about 450ppm or lower are likely to maintain warming below 2 degrees Celsius over the 21st century relative to pre-industrial levels." However, lead author on the paper Richard Betts said we could pass that number in 20 years or less. In an article on The Guardian, he said even if we reduce emissions immediately, we might be able to delay reaching 450ppm but "it is still looking like a challenge to stay below 450ppm." El Nino has played a significant role in climbing carbon dioxide levels, but it's likely we'll see higher CO2 levels than the last large El Nino storm during 1997 and 1998 because "manmade emissions" have risen by 25 percent since that storm, according to The Guardian. Met Office experts predicted in November 2015 that in May 2016 "mean concentrations of atmospheric CO2" would hit 407.57ppm -- the actual figure was 407.7ppm. The NOAA reported during 2015 that the "annual growth rate" of CO2 in the atmosphere rose by 3.05ppm. NOAA lead scientist Pieter Tans said, "Carbon dioxide levels are increasing faster than they have in hundreds of thousands of years. It's explosive compared to the natural processes."

    The science is in, the numbers are not fake, this is not a hoax. This is going to have serious global repercussions and it will never go away. We can't even yet stop contributing to the acceleration of emissions, they CONTINUE to grow year by year despite much-touted international accords. The science community agrees this will not be enough, and we are failing at this course correction necessity.

    At some point, the people being paid and those paying millions to put out the unreasonable position that this all is "no big deal" or "not certain to be a problem" or "not caused by human industry" etc, those people have to be dealt with. I make no suggestions beyond that general observation, that this is untenable.

    • It really doesn't matter, quite honestly. There is absolutely squat that people who give a damn about this can actually do that will make a difference, because there's far too many people who don't care what the world might be like in a hundred years, as long as they get to live the way they want to right now.

      I agree with you, but what you fail to accept is that the changes required to actually fix the problem are simply not acceptable... at least the average person won't accept them until it gets a LOT worse.

    Umm, but Ray Kurzweil told me if I take 200 pills per day and survive to the Singularity (which, apparently, is coming soon to a neocortex near you), then I'll live forever. And so will you.

    Does that mean CO2 levels will stay that high forever? Just wonderin'...

      Light a man a fire, and he will stay warm for a night. Set a man afire, and he will stay warm for a lifetime.

      Nothing is forever. Besides the eventual death of the planet and the loss of the atmosphere, some other process will bring CO2 levels back down long before then. Whether homo sapiens or any of its descendants will be around to see it is the actual question.

    Targeting CO2 emissions has always had a very long-term scope and we should continue to find ways to reduce them. However, in such urgent circumstances, we need to find greenhouse gas emissions that respond quickly to reducing their output. According to a UN report, 51% of greenhouse gases comes from animal agriculture, i.e. meat and dairy production. We don't all need to go vegan but we do need to stop eating such unhealthy and unsustainable amounts of meat.

    I'm not a vegetarian or vegan BTW.

      Easy now....what to do with people that cannot eat grain [like me]. Not talking about allergy - no glutamine bread is also no-no for me. However, without grain the efficiency of absorbing nutrients [at least in my case, but I have heard many similar stories] increases dramatically. My meat consumption is one or two [small, but high quality] dishes per week, two dishes per week fish and the rest is diary products and vegetables. It has become a bit of a party trick to tell people how little I eat while worki

  • El Nino has played a significant role in climbing carbon dioxide levels

    Wow, just when I thought I had heard global warming blamed on absolutely everything, and absolutely everything blamed on El Nino. But I never even considered blaming El Nino for carbon emissions.
