After years of La Niña conditions in the equatorial Pacific Ocean, scientists predict that El Niño is likely coming. Recent sea level data shows Kelvin waves rippling across this region, and these waves often act as a precursor to El Niño: sealevel.nasa.gov/news/263/inter…

“This coming year is gonna be a wild ride if the El Niño really takes off," says @omgnasa go.nature.com/3I43uxm

Got to see some more of the fjords around Nuuk and collect some more data with Mike Wood and @Lorenz_Meire today. Another beautiful day here! #science #climate

Got a tour of the Greenland Institute’s amazing new ship, the Tarajoq today from @Lorenz_Meire #science

@askjervedal It was great having you along that year and great to see you again!

Visual representation showing what data can do to improve knowledge for active use in practice. I got to help a tiny little bit on one of the final fieldtrips of the OMG project in ‘21 🇬🇱#longtermmonitoring #nasa #omg

So this guy made an appearance today. #ClimateElvis

How much is the ocean causing glacier melt-back in Greenland? @NASAJPL @omgnasa Dr Josh Willis provides an update on the omg.jpl.nasa.gov project that's revealing how sea water is interacting with Greenland's largest glaciers!

@YuengP @Lorenz_Meire Yes!

@omgnasa @Lorenz_Meire Cool egg-beater ice-avoidance frame?

Float deployed! With @Lorenz_Meire !

@Lorenz_Meire running some tests before we deploy. Everything looks good so far!

Since OMG ended Mike Wood and I have been working with @Lorenz_Meire from the Greenland Institute of Natural Resources. Today we are deploying this APEX float to monitor ocean conditions in the fjord north of Nuuk #omgnasa #climate #GINR

Headed back to Greenland!

@MarkA1865 @DrWKID There are also MANY other pieces of evidence that show it's CO2: The lower atmosphere is warming, while the upper atmosphere is cooling, suggesting heat is trapped by the changing atmosphere, more heat returns to Earth, less heat escapes to space... etc.

@omgnasa @DrWKID Recorded history is short here. Also, you that didn’t answer the question. You said CO2, which increased by over 33% since 1960, is driving the rise in sea level. Neither the earth’s temp nor sea level are rising as fast as CO2, which is odd If CO2 is the driver of both.

The rising oceans measured by satellites. Sea levels have gone up globally by over 9 centimeters in 30 years and the rate of rise has more than doubled in that time. #sealevelrise #NASA

@MarkA1865 @DrWKID The ocean requires at least 2000 years to completely adjust to a new atmosphere. But long records of both show that the only thing happening that can explain the warming and sea level rise of the last 150 years is humans adding CO2.

@TXPhoever Sea Level Rise Driving Increasingly Predictable Coastal Inundation in Sydney, Australia agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

@MarkA1865 @DrWKID By any measure, both CO2 and sea level are rising faster now than any other time in recorded history.

@omgnasa @DrWKID If CO2 is the cause, shouldn’t the sea level rise be increasing at a greater rate than the CO2 increase? Don’t the graphs look similar because of your choices with respect to the axis?

@TXPhoever And as you can see in the plot you posted, from about 6000 years ago to the present, sea levels have been stable, consistent with the VERY stable record over the last 2000 years (which I linked in my earlier tweet).

@TXPhoever Nope. In fact, sea levels were stable for about 2000 years after the end of the last ice age, and only started their rapid rise after the Industrial Revolution. nca2014.globalchange.gov/sites/report/f…

@crushdTin Over the short term (like one year or less) the water exchange is large, but in the longer term the loss of ice from glaciers and ice sheets is much bigger…

@omgnasa Perhaps this is a way to monitor moisture transport changes from ocean to land over long periods due to the massive desiccation of the continents. Surely the unperturbed vegetated moisture-laden landscapes sucked (pumped) oceanic moisture inland.
