Sea Levels Drop, Himalayas Aren’t Melting

First we have this interesting detail from NASA:

NASA Satellites Detect Pothole on Road to Higher Seas

The red line in this image (above) shows the long-term increase in global sea level since satellite altimeters began measuring it in the early 1990s. Since then, sea level has risen by a little more than an inch each decade, or about 3 millimeters per year.

While most years have recorded a rise in global sea level, the recent drop of nearly a quarter of an inch, or half a centimeter, is attributable to the switch from El Niño to La Niña conditions in the Pacific

The insets show sea level changes in the Pacific Ocean caused by the recent El Niño and La Niña

Funny how this good news is not being trumpeted by our media watchdogs. You would think they would want to celebrate it, since it is rare instance of Obama fulfilling a campaign promise.

By the way, note the tacit admission that it is El Nino and La Nina who are controlling this. And not man-made global warming.

On another front, we have this from the UK’s (relentlessly green) Guardian:

The Himalayas and nearby peaks have lost no ice in past 10 years, study shows

Meltwater from Asia’s peaks is much less than previously estimated, but lead scientist says the loss of ice caps and glaciers around the world remains a serious concern

Damian Carrington

The world’s greatest snow-capped peaks, which run in a chain from the Himalayas to Tian Shan on the border of China and Kyrgyzstan, have lost no ice over the last decade, new research shows.

The discovery has stunned scientists, who had believed that around 50bn tonnes [55.1 US tons] of meltwater were being shed each year and not being replaced by new snowfall.

These global warming ‘scientists’ are surprised more often than the media’s economists.

The study is the first to survey all the world’s icecaps and glaciers and was made possible by the use of satellite data. Overall, the contribution of melting ice outside the two largest caps – Greenland and Antarctica – is much less than previously estimated, with the lack of ice loss in the Himalayas and the other high peaks of Asia responsible for most of the discrepancy.

Bristol University glaciologist Prof Jonathan Bamber, who was not part of the research team, said: "The very unexpected result was the negligible mass loss from high mountain Asia, which is not significantly different from zero."

The melting of Himalayan glaciers caused controversy in 2009 when a report from the UN’s Intergovernmental Panel on Climate Change mistakenly stated that they would disappear by 2035, instead of 2350. However, the scientist who led the new work is clear that while greater uncertainty has been discovered in Asia’s highest mountains, the melting of ice caps and glaciers around the world remains a serious concern.

"Our results and those of everyone else show we are losing a huge amount of water into the oceans every year," said Prof John Wahr of the University of Colorado. "People should be just as worried about the melting of the world’s ice as they were before."

His team’s study, published in the journal Nature, concludes that between 443-629bn tonnes of meltwater overall are added to the world’s oceans each year. This is raising sea level by about 1.5mm a year, the team reports, in addition to the 2mm a year caused by expansion of the warming ocean

And yet the sea levels went down in 2010. And, according to NASA, they seem to be determined by El Nino and La Nina.

Wahr warned that while crucial to a better understanding of ice melting, the eight years of data is a relatively short time period and that variable monsoons mean year-to-year changes in ice mass of hundreds of billions of tonnes. "It is awfully dangerous to take an eight-year record and predict even the next eight years, let alone the next century," he said.

Huh. Funny how the records are long enough when they show what they want them to show.

The reason for the radical reappraisal of ice melting in Asia is the different ways in which the current and previous studies were conducted. Until now, estimates of meltwater loss for all the world’s 200,000 glaciers were based on extrapolations of data from a few hundred monitored on the ground. Those glaciers at lower altitudes are much easier for scientists to get to and so were more frequently included, but they were also more prone to melting.

The bias was particularly strong in Asia, said Wahr: "There extrapolation is really tough as only a handful of lower-altitude glaciers are monitored and there are thousands there very high up."

And these ‘scientists’ did not take that into account?

The new study used a pair of satellites, called Grace, which measure tiny changes in the Earth’s gravitational pull. When ice is lost, the gravitational pull weakens and is detected by the orbiting spacecraft. "They fly at 500km, so they see everything," said Wahr, including the hard-to-reach, high-altitude glaciers

Well, Grace can kiss her government funding goodbye.

    Do you ever get the impression that climate scientists are playing a board game that is controlled by rolling dice?

    • Curiosity says:

      As a (the) NASA Federally Funded Research and Development Center, Jet Propulsion Laboratory is desperately trying last through low NASA funding and retain its talent by chasing whatever money is out there. It seemed like last summer a full third of their work was climate oriented.

    • tranquil.night says:

      So true Curiosity. Much of how they control the agenda in academia and science relates to how their policies intentionally pervert and incentivize the research markets. The statists help the envirofascists by doing things like declaring climate change a national security threat to manufacture paranoia, thus demand for everything from more state action, more preparation – more research, and, of course, green tech.

      Just look to Spain for answers to how well that “green” economy works.

      But who are we fooling. We know at the top it’s just another redistributionist scam from the corrupt masterminds and their cronies lookin’ for the easy buck.

  2. GetBackJack says:

    Did you know Global Warming Deniers are causing the Earth to lose 50,000 tonnes of it’s mass … every year!!

    BBC. So you know it’s true …

  3. JohnMG says:

    Every drop of water in the world is recycled over and over. It’s not like your gas tank which will eventually run dry. Nature maintains her own balance.

    But for these morons, the ocean is like your bath tub……if we don’t stop the melting it’s gonna run over. They’re still trying to figure out where it will go. I’m sure if we can just give them some more money they’ll figure it out. /s/
