NASA Scientists Puzzled by Global Cooling on
Land and Sea
The deep ocean
may not be hiding heat after all, raising new questions about why global
warming appears to have slowed in recent years, said the US space agency
Monday.
Scientists have
noticed that while greenhouse gases have continued to mount in the first part
of the 21st century, global average surface air temperatures have stopped
rising along with them, said NASA.
Some studies
have suggested that heat is being absorbed temporarily by the deep seas, and
that this so-called global warming hiatus is a temporary trend.
But latest data
from satellite and direct ocean temperature measurements from 2005 to 2013
"found the ocean abyss below 1.24 miles (1,995 meters) has not warmed
measurably," NASA said in a statement.
The findings
present a new puzzle to scientists, but co-author Josh Willis of NASA's Jet
Propulsion Laboratory (JPL) said the reality of climate change is not being
thrown into doubt. "The sea level is still rising," said
Willis."We're just trying to understand the nitty-gritty details."
A separate
study in August in the journal Science said the apparent slowdown in the
Earth's surface warming in the last 15 years could be due to that heat being
trapped in the deep Atlantic and Southern Ocean.
But the NASA
researchers said their approach, described in the journal Nature Climate
Change, is the first to test the idea using satellite observations, as well as
direct temperature measurements of the upper ocean. "The deep parts of the
ocean are harder to measure," said researcher William Llovel of NASA JPL.
"The
combination of satellite and direct temperature data gives us a glimpse of how
much sea level rise is due to deep warming. The answer is -- not much."

Now can we forget carbon capture
? Can we keep our coal-fired power
plants ? Can we remove carbon from the
EPA kill list ?
