Global Temperatures Highest in 4,000 Years

Bad news for planet Earth, new research shows global warming is at an all-time high and things are only getting hotter.

“Global temperatures are the warmest they’ve been in some 4,000 years and although climate change is natural they say such rapid warming is a threat because we don’t have much time to adapt to it as we’ve had in the past.” (Via Good Morning America)

Researchers at Oregon State University and Harvard reconstructed Earth’s temperature history for the past 11,300 years. The results put global warming into a larger context and showed the planet is warmer now than 90 percent of that time. (Via Journal Science)

Pretty startling evidence, seeing that previous studies had only gone back around 2,000 years. The National Science Foundation reiterates what’s problematic about the finding.

“During the last 5,000 years, the Earth on average cooled about 1.3 degrees Fahrenheit — until the last 100 years, when it warmed about 1.3 degrees.

.. Climate models project that global temperatures will rise another 2 to 11.5 degrees Fahrenheit by the end of this century.”

Not to mention this rise in temperatures may be the opposite of what the Earth’s temperatures should be naturally.

A writer for NBC focused on this graphic showing the Earth was in the process of cooling off. It references a 5,000-year span where the planet’s temperature dropped 1.3 degrees. But then, it starts to increase. Why?

CNN quotes the study’s lead researcher as saying, “if not for man-made influences, the Earth would be in a very cold phase right now and getting even colder.”

Man-made influences like burning fossil fuels. And while we, humans, are aware these temperature changes are coming, The New York Times says surviving in them is another story.

“The modern spike would probably threaten the survival of many species, in addition to putting severe stresses on human civilization.
