Bad News, Global Warming: Some Scientists Say Earth Has Actually Been Cooling Off For 2,000 Years Now [Study]

Scientists say earth has been cooling for 2,000 years

Bad news, global warming enthusiasts. The world was actually warmer in Roman and Medieval times than it is now. In fact, the world has been on a cooling trend for the past 2,000 years, according to new research.

The study says that tree-rings hold the secret to understanding the history of climate change, and that the rings of fossilized trees show that the earth actually used to be much warmer than it is today, and has even been slowly cooling down. “Measurements stretching back to 138BC prove that the Earth is slowly cooling due to changes in the distance between the Earth and the sun,” notes the Daily Mail.

“We found that previous estimates of historical temperatures during the Roman era and the Middle Ages were too low,” says Professor-Doktor Jan Esper of the Johannes Gutenberg-Universität Mainz, one of the scientists leading the study. “Such findings are also significant with regard to climate policy.”

The science: Tree rings are actually very helpful in the reconstruction of long-term temperature trends. The assumption is that warmer summers make for wider rings. Esper thinks that some rings actually show a long-term cooling trend, where traditional assumptions show little-to-no change until relatively recently. Esper’s says that the cooling trend is thanks to reduced solar heating caused by changes to the Earth’s orbit known as Milankovitch wobbles. His results put the Roman era at 0.6 °C warmer than previously thought, making it warm enough for alleged grape vines in northern England to be a possibility.

Though the research is still new and unchallenged as of the now, the findings do support other studies in the same vein – findings such as the chemical makeup of air trapped in glaciers and the organic remains in ancient lake sediments have also suggested a cooling trend, notes New Scientist.

    Whoever wrote this is either not particularly bright, or intentionally misleading the reader.

    (Bottom line up front: this study, if valid, would prove humans are causing Global Warming at a faster rate than previously estimated).

    The earth cycles through a millennia-long climate swing, when for a few millennia it cools, and then for the same period of time it warms. Until the mid-19th century Earth was in one of its cooling periods.

    Scientists who claim human-caused CO2 emissions contribute to Climate Change say the latest cooling period was interrupted in the mid-19th century. Others think the entire cycle is more "flexible," and that the Climate Change we're seeing now is actually a function of natural causes.

    What this study, and a few others since 2008, have shown is that the earth was cooling at a faster rate than previously estimated when the interruption happened in the mid-1800s. Thus, temperatures between the Roman era and 1776, for example, show a faster cooling trend (because it was warmer in the Roman era than previously thought). This is evidence the "humans are causing it" argument is valid, and that the cooling trend interruption around 1850ish was not a function of natural causes.

    In other words, these data actually do more to prove humans (and not just natural forces) are causing Climate Change.

    Unfortunately, this story one of those things bound to be misinterpreted by many who still insist Climate Change is fiction (and can't read very well), and willfully misrepresented by others who know better.

    Inquisitr: which are you?

    Hey Phil…what's wrong with you, other than been a pathetic leftist libetard water boy parasite?
    Global Warming is a fabrication by the filthy parasites of the left and their puppets, the libetards! How many time we're going to have to prove that the miserable paid-off so called "scientist" fabricated niumbers in order to prove their marxist ideology? When was the last time the anti-American leftist loser of Al Gore told a single true? Al "the loser" Gore hates America! Even his own wife left him because he's an Anti-American, not only that, she knew about his fabricated global warming fiasco! the biggest lie in the USA is call barack Hussein obama/Barry Soetoro or whatever is his real name, the second one is global warming, of couse, Al "The Loser" Gore!

    Or it could possibly be that global warming is yet another 'scare tactic' by the left to initiate more govt involvement/policies in our lives.

    Climate Change isn't fiction…It's just 99.996% natural.

    This all stays open for debate, who ever claims to know for certain what's causing the global warming is the ONE WHO IS NOT BRIGHT! We can't be absolutely sure of what's causing the global warming, since there way too many who claim humans are causing it, and many who say it's because of natural causes… Let's just keep an open mind and consider both options, on one side it helps us try to find better solutions to our living on the other side it helps us to explore and study more to be more informed!
