Story Highlights
New research indicates that the Earth is warmer now than it has been in
roughly 120,000 years.

It is also poised to break a 2-million-year temperature record.

A new study paints a picture of an Earth that is warmer than it has been
in about 120,000 years, and is locked into eventually hitting its hottest
mark in more than 2 million years.

As part of her doctoral dissertation at Stanford University, Carolyn
Snyder , now a climate policy official at the U.S. Environmental
Protection Agency, created a continuous 2 million year temperature record,
much longer than a previous 22,000-year record. Snyder’s temperature
reconstruction, published Monday in the journal Nature , doesn’t estimate
temperature for a single year but averages 5,000-year time periods going
back a couple million years.


Snyder based her reconstruction on 61 different sea surface temperature
proxies from across the globe, such as ratios between magnesium and
calcium, species makeup and acidity. But the further the study goes back
in time, especially after half a million years, the fewer of those proxies
are available, making the estimates less certain, she said.

These are rough estimates with large margins of errors, she said. But she
also found that the temperature changes correlated well to carbon dioxide
levels.

Temperatures averaged out over the most recent 5,000 years — which
includes the last 125 years or so of industrial emissions of heat-trapping
gases — are generally warmer than they have been since about 120,000 years
ago or so, Snyder found. And two interglacial time periods, the one
120,000 years ago and another just about 2 million years ago, were the
warmest Snyder tracked. They were about 3.6 degrees (2 degrees Celsius)
warmer than the current 5,000-year average.

With the link to carbon dioxide levels and taking into account other
factors and past trends, Snyder calculated how much warming can be
expected in the future.

Snyder said if climate factors are the same as in the past — and that’s a
big if — Earth is already committed to another 7 degrees or so (about 4
degrees Celsius) of warming over the next few thousand years.

“This is based on what happened in the past,” Snyder said. “In the past,
it wasn’t humans messing with the atmosphere.”

Scientists give various reasons for past changes in carbon dioxide and
heat levels, including regular slight shifts in Earth’s orbital tilt.

Four outside scientists praised the study’s tracking of past temperatures,
with caveats about how less certain it is as it gets deeper in the past.
Jeremy Shakun of Boston College said. “Snyder’s work is a great
contribution and future work should build on it.”

But many of the same scientists said Snyder’s estimate of future warming
seems too high. Shakun called it unrealistic and not matching historical
time periods of similar carbon dioxide levels.

A fifth scientist, Michael Mann of Pennsylvania State University, called
the study provocative and interesting but said he remains skeptical until
more research confirms it. He found the future temperature calculations
“so much higher than prevailing estimates that one has to consider it
somewhat of an outlier.”

Or maybe an "out-and-out liar".
