National Academy of Sciences warns Earth could become ‘hothouse’

    National Academy of Sciences warns Earth could become 'hothouse'Thinking of buying a new RV? You might want to consider adding an extra air conditioner, a larger awning complete with sunshades all around, and spending more time at campgrounds in higher altitudes.

    According to a report by the National Academy of Sciences, a domino effect will kick in if global temperatures rise more than 2°C above pre-industrial levels, leading to “hothouse” conditions and higher sea levels, reports CNN.


    And if you think some areas of the country are already uninhabitable in some seasons, just wait. It could get worse.

    The report, “Trajectories of the Earth System in the Anthropocene,” published Monday in the American Proceedings of the National Academy of Sciences, said “hothouse” temperatures could stabilize 7 to 9 degrees higher than pre-industrial levels.

    “Human greenhouse gas emissions are not the sole determinant of temperature on Earth. Our study suggests that human-induced global warming of 2°C may trigger other Earth system processes, often called ‘feedbacks,’ that can drive further warming – even if we stop emitting greenhouse gases,” lead author Will Steffen of the Australian National University said.

    Hotter temperatures could result in sea level rise up to 197 feet from today’s shorelines, swallowing coastal populations and forcing communities to relocate inland. This summer dozens of people have died in wildfires and heat waves from the U.S. to Asia, giving the world an insight into what could lie ahead.

    The report says that if the “threshold” – a theoretical point-of-no-return – is crossed, this “would lead to a much higher global average temperature than any interglacial period in the past 1.2 million years” and to sea levels significantly higher than at the end of the last ice age about 12,000 years ago.

    Willful ignorance will not change the outcome. I’ve lived through decades of “non-believers” challenging everything from effects of water pollution to limitations of miles-per-gallon obtainable by internal combustion engines. I just wish I had been one of those selling “miracle” additives and “breakthrough” mechanical gadgets that promised to double the mileage for only $19.95…….

    The fact remains that automobiles have finite efficiencies and the dead zone off the gulf of Louisiana continues to expand with no marine life able to live in those waters. Here in Minnesota we’re seeing various pests and insects that previously wouldn’t have survived the inhospitable climate. What the hell do you do with termites?

    Those of us who believe in the scientific method over what some “performance artist” radio/TV hosts present (their goal of ratings is as important as, or more important than, providing factual information) have pretty much given up on trying to educate those invested in this nonsense. We simply work harder to prevent policies and regulations that cause these problems and ignore the grumbling of those who feign injury and outrage.

    There are volumes of articles that look at this issue from a true untainted angle. I encourage all of you believers to search it out.

    When the money is on one side, be Leary.

    I yawn at these articles from so-called “experts” who have no clue. I remember back in the 70’s we were told there was a coming ice age, and we were on the brink of destruction. Well, when that didn’t happen, along came Al Gore and his movie “Inconvenient Truth” where he told us human-caused global warming was bringing us to the brink of destruction. The REAL truth is, the earth goes through phases of heating and cooling. This has been going on since before even microbes lived on earth. Man’s ‘life’ on earth doesn’t even amount to a pimple on a pimple. We’re not causing climate change, we can’t stop climate change, and it will go on forever, long after we’re wiped off the face of the earth due to, I don’t know, something else we can’t control. In the meantime, we just have to make whatever changes we can in OUR lives to cope with it.

    The scientists have no clue. We have entered a period called a Grand Solar Minimum. Meaning, we are entering a cooling/cold phase for the earth for likely until 2040s. Expect unusual to record cold in most parts of the world.
    Previous periods reveal snow falling in the middle of summer in Texas and parts near and the reforming of glaciers. The major concern will be the effect on crops, i.e., increase food prices, shortages, etc. one must remember that the Al Gore era of global warming was founded on falsified records. So summarizing for this report, literally everyone, “CHILL”. I could go on.
