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.

8 Thoughts to “National Academy of Sciences warns Earth could become ‘hothouse’”

    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.

    Sol, what you’re saying is that trained and educated scientists, who make the study of the earth’s climate their life’s work, “have no clue” but you do? What is the source of your information?

    1. Billy Bob Thorton

      Bob,

      Al Gore is one reference. That huckster..made millions on the whole global warming scam.

      Or, how about when global warming didn’t pan out from these nuts, they switched up to climate change.

      There are tons of peer review articles that say climate changes all the time, but the big money is on the nuts side, so the whole thing just bores the masses now, and it’s losing steam. Until this winter, why you ask, we’ll you see there is a big .el.nino building in the Pacific, which will bring a mild winter, here. It’s just science, the ongoing study. But the nuts, will launch off it, write their kook review articles, and be hero’s at their coffee shop worshippers circles.

    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.

      I agree with you, several years ago I watched a TV show in Chicago about cyclical cooling and heating of the earth by a local weatherman who everyone thought was a clown, who later became the founder of the Weather Channel, John Coleman. He said the earth goes through a 100 year cyclical cycle, 50 years of heating and 50 years of cooling. I can remember how cold it was back in the 50s and 60s, remember the snow storm in 1967 that dumped snow on the Midwest crippling everything. As well as other parts of the country. More recently this past winter when it was so cold everywhere, we were in south Florida with night time temperatures in the low 40’s, where snow fell in Tallahassee and Jacksonville, I asked then if this is the global warming Al Gore warned us about. A lot of scientists earn their living on federal grants, when the time limit starts to run out on their grant they have to show something for the money they took, so they come up with a theory so unbelievable that people believe it especially the lawyers in congress. Just my thoughts on the subjects.

      Skiing will be fantastic. I love this country.
