Study Refutes Manmade Global Warming

by Roberta Seldon on April 2, 2012

Recently, the Intergovernmental Panel on Climate Change (IPCC) argued that the global warming that took place during medieval times was confined to Europe only and had no effect on the rest of the planet. However, researchers led by geochemist Zunli Lu from Syracuse University found that the warming had actually affected the entire planet, extending all the way down to Antarctica. This finding indicates that “the Earth has already experienced global warming without the aid of human CO2 emissions,” according to the Daily Mail.

Following that period, the Earth cooled down naturally and even experienced a “mini ice age.”

The study, published in the journal Earth and Planetary Science Letters, relied on data collected from ikaite — a rare mineral that is an icy version of limestone that forms in cold waters. The water that holds crystals of ikaite together contains information about temperatures present when the crystals were formed.

The researchers studied ikaite crystals from sediment cores drilled off the coast of Antarctica. According to the Mail, the researchers say that the crystals show that the Medieval Warm Period and Little Ice Age extended to Antarctica.

The Mail observed: “Is this finally proof we’re not causing global warming?”

BLOGGER’S NOTE: Even if the Medieval Warm Period wasn’t manmade, we’re still contributing to global warming via CO2 emissions, deforestation, urbanization and other human activities that change the atmosphere’s composition? How is this study proof that we’re not causing global warming?!? What do you think? Share your thoughts below.
