A suspected 15-year lull in global warming, seized upon by climate-change
skeptics as evidence that climate change had ground to a halt, never
happened, say Stanford researchers, who blame the costly misunderstanding on
faulty statistical methods.
Their findings debunk the idea that global warming stalled or slowed down
between 1998 and 2013, despite the fact that numerous climate studies
purported otherwise.
“We find compelling evidence that recent claims of a ‘hiatus’ in global
warming lack sound scientific basis,” the authors said in the study
released Thursday in the journal Climatic Change.
The researchers performed a full analysis of statistics gathered by
scientists to measure temperature changes in the Earth, breaking down and
testing four core claims behind what was interpreted as a global warming
lull. The claims were similar but technically different, that:
•The average rate of global warming had slowed down.
The group started its research after the hiatus was a major focus of the
2013 climate change assessment by the U.N. Intergovernmental Panel on
Climate Change.
“We started to hear a lot about the hiatus in everything, from the news
media to peer-reviewed journals,” said Bala Rajaratnam, an assistant
professor of statistics and of Earth system science at Stanford.
A new approach
To test whether it was actually occurring, he and his team used a new
statistical framework designed specifically to look at processes like global
temperature fluctuations. Their intent was to examine temperature data and
the statistical tools scientists had used previously to reach their
conclusions about a lull or hiatus.
One by one, the researchers found all four claims had no statistical backing
. They found that in many cases, those scientists had used “faulty
statistical methods.”
“It doesn’t mean those studies are wrong,” said Noah Diffenbaugh, a
climate scientist in the university’s School of Earth, Energy &
Environmental Sciences and a co-author of the study. “They have generated a
lot of important understanding that look at the processes of how global
temperatures vary over a long-term period.”
And, he said, the new study should not be used to question a body of
scientific work that shows climate change is occurring.
“Our analysis shows that there hasn’t been any slowdown or pause,”
Diffenbaugh said. “Rather, it showed that global temperature is a noisy
system that goes up and down, but that the long-term trend of global warming
persists.”
He and his colleagues hope their findings go a long way toward restoring
confidence in the basic science and climate computer models that form the
foundation for future climate change.
Their study is just the latest in a number of findings that have cast doubt
on the existence of the global warming lull.
Skewed by ocean buoys
For example, a study led by Thomas Karl, a director at the National Oceanic
and Atmospheric Administration, in June showed that ocean buoys that read
cooler temperatures than their counterparts on ships accounted for false
signs of the hiatus. The researchers for that team corrected their data,
adjusting for the buoys’ cooler temperature readings, and subsequently
removed all signs of the warming hiatus.
Anthony Arguez, a climate scientist at NOAA and a co-author of that June
paper, said the new Stanford study looks at global warming in a different,
but very robust way.
“Based on the current state of the science, I would consider this to be a
significant step forward mostly because I share the authors’ bewilderment
that the scientific community has made statements about a so-called hiatus
without more rigorous statistical considerations,” Arguez said in an e-mail.
Rajaratnam wants the studies to move the debate beyond a belief in a climate
change lull. Researchers, he said, have spent countless dollars and
performed numerous studies to investigate potential causes of the hiatus.
Instead, he said, funding should be used directly for dealing with global
warming.
Allocating resources
“A lot of money has been poured into global warming mitigation efforts,”
he said. “The question is, because there was this purported slowdown, are
we spending these funds the best way possible? Did we allocate our resources
as best as possible because it didn’t seem as severe as it was at the time
?”
The release of the Stanford study coincided with a monthly climate update
from NOAA, which showed August as the warmest month on record for overall
land and ocean temperatures.
