blasted into orbit Sunday with a $364 million satellite, the latest in a series to measure the Earth’s sea levels. The satellite, dubbed Jason-3, will measure sea levels around the world, which many climate alarmists claim are rising faster even though traditional measuring devices say otherwise (see graph). Jason-3 is a combined effort of the National Oceanic and Atmospheric Administration (NOAA), the National Aeronautics and Space Administration (NASA), the French space agency CNES and EUMETSAT, and the European agency that manages weather satellite data.Just off the California coast, a SpaceX Faclon 9 rocket
Dubbed an environmental research satellite, the satellite was boosted into orbit by Elon Musk’s private SpaceX company, which has taken over many duties previously done by NASA after the long-running shuttle program was dismantled and memorialized. You may remember Elon Musk as the guy who wanted to nuke the poles on Mars to kick-start terraforming the red planet.
One goal of this recent mission was to recover the Falcon 9’s first-stage rocket, an expensive piece of equipment that is normally burned up in the atmosphere. That part was a failure; after releasing its payload, it descended back to Earth, but it failed a return landing on a giant barge floating in the Pacific Ocean. The rocket tipped over and exploded (see video).
NASA also launched satellites in 1978 to measure global temperatures and said it was the gold standard that all agencies should adopt. But when the dataset showed no statistical warming for the last two decades, it was promptly ignored. Then activists took to YouTube with a new video trying to discredit the satellite readings. Will the same fate befall Jason and his orbital brothers if sea level rise doesn’t increase as predicted by global warming activists?
The Jason-3 is the fourth in a series of satellites that uses “state-of-the-art radar altimeters to measure the distance to the ocean surface below with extraordinary accuracy, allowing researchers to calculate ocean elevation, deep ocean temperatures, the velocity of currents, wave height and wind speed.” NOAA told CBS News that the Jason-3 is “designed expressly for monitoring sea level rise” and ocean topography.
Just like on land, the ocean’s surface topography has “highs and lows, similar to the hills and valleys of Earth’s land surface.” The satellites use sophisticated mathematical equations to measure the sea surface height relative to the Earth’s geoid (the hypothetical shape of the earth). For example, if there is a large mountainous region beneath the ocean, the sea surface above that area would “bulge”, making the sea surface higher in that area. Mapping the ocean’s unseen surface is important because this topography affects the ocean currents, heights, behavior, and more.
According to the satellite’s specs, instruments will collect data to help scientists and weather forecasters improve modeling of “extreme” weather from hurricanes to tropical storms. Incidentally, there has been no increase in extreme weather based on current data, but certain areas have become heavily populated in the last 50 years, regions that should never have been developed or inhabited.
Miller, who said isolated events like “heavy rainfall, flooding, tornadoes out of season, and droughts” may seem like isolated events but many, if not all, are connected to the ongoing naturally occurring El Niño event happening in the tropical Pacific Ocean. El Niños occur every 6-8 years and can affect weather all over the world. The current El Niño has been ranked as being in the top three since recordkeeping began in the 1950s.
Over the next couple of weeks, the Jason-3 will be aligned in a nearly identical orbit as the Jason-2, launched in 2008. The two satellites will allow engineers to “precisely calibrate Jason-3’s instruments so its data are consistent with Jason-2’s.” Six months from then, the Jason-2 will be moved into a different orbit to improve global coverage.
According to Josh Willis, the Jason-3 project scientist at NASA, “Jason-3, much like its predecessor Jason-2, will be able to measure the height of the ocean in an area that’s about six miles across from 800 miles up with an accuracy of about one inch, so about the width of a quarter.” They believe that the data they get from the Jason-2 will “allow them to have accurate measures for ocean levels that are better than half a centimeter (cm).” Since 1992, NOAA says, global sea levels have risen about three millimeters (mm) per year, less than half a centimeter (10 mm = 1 cm). That’s smaller than what the satellites are able to accurately measure.
